Preface

This manual provides reference information about database initialization parameters, static data dictionary views, dynamic performance views, database limits, and SQL scripts that are part of the Oracle Database.

Oracle Database Reference contains information that describes the features and functionality of the Oracle Database (also known as the standard edition) and the Oracle Database Enterprise Edition products. The Oracle Database and the Oracle Database Enterprise Edition have the same basic features. However, several advanced features are available only with the Enterprise Edition, and some of these are optional. For example, to use application failover, you must have the Enterprise Edition with the Real Application Clusters option.

Part I

Initialization Parameters

This part describes the database initialization parameters that can be specified in a parameter file to start or configure an instance. This part contains the following chapter:

- Chapter 1, "Initialization Parameters"

1 Initialization Parameters

This chapter contains detailed descriptions (in alphabetical order) of the database initialization parameters.

This chapter contains the following topics:

- Uses of Initialization Parameters

- Basic Initialization Parameters

- Parameter Files

- Changing Parameter Values in a Parameter File

- Reading the Parameter Descriptions

- Initialization Parameter Descriptions

Uses of Initialization Parameters

Initialization parameters fall into various functional groups. For example, parameters perform the following functions:

- Set limits for the entire database

- Set user or process limits

- Set limits on database resources

- Affect performance (these are called variable parameters)
Variable parameters are of particular interest to database administrators, because these parameters are used primarily to improve database performance.

Database administrators can use initialization parameters to:

- Optimize performance by adjusting memory structures, such as the number of database buffers in memory

- Set database-wide defaults, such as the amount of space initially allocated for a context area when it is created

- Set database limits, such as the maximum number of database users

- Specify names of files or directories required by the database

Many initialization parameters can be fine-tuned to improve database performance. Other parameters should never be altered or should be altered only under the supervision of Oracle Support Services.

All initialization parameters are optional. Oracle has a default value for each parameter. This value may be operating system-dependent, depending on the parameter.

Types of Initialization Parameters

The Oracle database server has the following types of initialization parameters:

- Derived Parameters

- Operating System-Dependent Parameters

- Variable Parameters (these can be dynamic parameters or any of the preceding ones)

Derived Parameters

Some initialization parameters are derived, meaning that their values are calculated from the values of other parameters. Normally, you should not alter values for derived parameters, but if you do, then the value you specify will override the calculated value.

For example, the default value of the SESSIONS parameter is derived from the value of the PROCESSES parameter. If the value of PROCESSES changes, then the default value of SESSIONS changes as well, unless you override it with a specified value.

Operating System-Dependent Parameters

The valid values or value ranges of some initialization parameters depend upon the host operating system. For example, the parameter DB_BLOCK_BUFFERS indicates the number of data buffers in main memory, and its maximum value depends on the operating system. The size of those buffers, set by DB_BLOCK_SIZE, has an operating system-dependent default value.

See Also:

Your operating system-specific Oracle documentation for more information on operating system-dependent Oracle parameters and operating system parameters

Variable Parameters

The variable initialization parameters offer the most potential for improving system performance. Some variable parameters set capacity limits but do not affect performance. For example, when the value of OPEN_CURSORS is 10, a user process attempting to open its eleventh cursor receives an error. Other variable parameters affect performance but do not impose absolute limits. For example, reducing the value of DB_BLOCK_BUFFERS does not prevent work even though it may slow down performance.

Increasing the values of variable parameters may improve your system's performance, but increasing most parameters also increases the system global area (SGA) size. A larger SGA can improve database performance up to a point. In virtual memory operating systems, an SGA that is too large can degrade performance if it is swapped in and out of memory. Operating system parameters that control virtual memory working areas should be set with the SGA size in mind. The operating system configuration can also limit the maximum size of the SGA.

Basic Initialization Parameters

The following is a list of the database basic initialization parameters. Most databases should only need to have basic parameters set to run properly and efficiently. Oracle advises you to become familiar with the basic parameters and only use other parameters when directed to by feature documentation or in special circumstances:

CLUSTER_DATABASE
COMPATIBLE
CONTROL_FILES
DB_BLOCK_SIZE
DB_CREATE_FILE_DEST
DB_CREATE_ONLINE_LOG_DEST_n
DB_DOMAIN
DB_NAME
DB_RECOVERY_FILE_DEST
DB_RECOVERY_FILE_DEST_SIZE
DB_UNIQUE_NAME
INSTANCE_NUMBER
LDAP_DIRECTORY_SYSAUTH
LOG_ARCHIVE_DEST_n
LOG_ARCHIVE_DEST_STATE_n
NLS_LANGUAGE
NLS_TERRITORY
OPEN_CURSORS
PGA_AGGREGATE_TARGET
PROCESSES
REMOTE_LISTENER
REMOTE_LOGIN_PASSWORDFILE
SESSIONS
SGA_TARGET
SHARED_SERVERS
STAR_TRANSFORMATION_ENABLED
UNDO_TABLESPACE

Parameter Files

A parameter file is a file that contains a list of initialization parameters and a value for each parameter. You specify initialization parameters in a parameter file that reflect your particular installation. Oracle supports the following two types of parameter files:

- Server Parameter Files

- Initialization Parameter Files

Server Parameter Files

A server parameter file is a binary file that acts as a repository for initialization parameters. The server parameter file can reside on the machine where the Oracle database server executes. Initialization parameters stored in a server parameter file are persistent, in that any changes made to the parameters while an instance is running can persist across instance shutdown and startup.

Initialization Parameter Files

An initialization parameter file is a text file that contains a list of initialization parameters. The file should be written in the client's default character set.

The following are sample entries in an initialization parameter file:

PROCESSES = 100
OPEN_LINKS = 12
GLOBAL_NAMES = true

The name of the initialization parameter file varies depending on the operating system. For example, it can be in mixed case or lowercase, or it can have a logical name or a variation of the name init.ora. Also supplied is an initdw.ora file, which contains suggested parameter settings for data warehouses and data marts. The database administrator can choose a different filename for the initialization parameter file.

Refer to your operating system-specific Oracle documentation for the default locations and filenames for initialization parameter files on your operating system. The initialization parameter file is read by the client-side tool used to start the server (such as SQL*Plus).

Sample initialization parameter files are provided on the Oracle distribution medium for each operating system. A sample file is sufficient for initial use, but you will probably want to modify the file to tune the database for best performance. Any changes will take effect after you completely shut down and restart the instance.

Specifying Values in an Initialization Parameter File

This section describes several aspects of setting parameter values in an initialization parameter file.

Rules Governing Initialization Parameter Files

The following rules govern the specification of parameters in initialization parameter files:

- An initialization parameter file should contain only parameters and comments. A pound sign (#) starts a comment line. The rest of the line is ignored.

- You can specify parameters in any order.

- Case (upper or lower) in filenames is significant only if case is significant on the host operating system.

- To enter several parameters on one line, use spaces between parameter names and values, as in the following example:

PROCESSES = 100 CPU_COUNT = 1 OPEN_CURSORS = 10

- Some parameters, such as ROLLBACK_SEGMENTS, accept multiple values. Any of the following represent valid syntax.

- Enter multiple values enclosed in parentheses and separated by commas. For example:

ROLLBACK_SEGMENTS = (SEG1, SEG2, SEG3, SEG4, SEG5)

- Enter multiple values without parentheses and commas. For example:

ROLLBACK_SEGMENTS = SEG1 SEG2 SEG3 SEG4 SEG5

- Enter multiple values, one per line. For example:

ROLLBACK_SEGMENTS = SEG1
ROLLBACK_SEGMENTS = SEG2
ROLLBACK_SEGMENTS = SEG3
ROLLBACK_SEGMENTS = SEG4
ROLLBACK_SEGMENTS = SEG5

If you enter values for one parameter on multiple lines, then the entries must be on consecutive lines. If they are not, then the first entry will not be processed properly. For example, in the following entry the setting for SEG3 and SEG4 will override the setting for SEG1 and SEG2:

ROLLBACK_SEGMENTS = SEG1 SEG2
OPEN_CURSORS = 10
ROLLBACK_SEGMENTS = SEG3 SEG4

- A backslash (\), also known as an escape character, indicates continuation of the parameter specification. If a backslash continues a line, then the continued line must have no leading spaces. For example:

ROLLBACK_SEGMENTS = (SEG1, SEG2, \
SEG3, SEG4, SEG5)

- You can use the IFILE initialization parameter to embed the contents of another initialization parameter file into the current initialization parameter file.

- Enclose in quotation marks any parameter values that contain spaces or tabs. You can use either single or double quotation marks unless otherwise indicated. For example:

NLS_TERRITORY = 'CZECH REPUBLIC'

Note:

Listing parameters in alphabetical order in the initialization parameter file can help you to find them and can help ensure that each parameter is specified only once.

- Enclose in quotation marks any parameter value that contains a special character.

See Also:

- Your operating system-specific Oracle documentation for more information on initialization parameter files

- "IFILE"

Using Special Characters in Parameter Values

If a parameter value contains a special character, then the special character must be preceded by a backslash or the entire parameter value must be enclosed in quotation marks. For example, you can specify special characters using either of the following:

DB_DOMAIN = 'JAPAN.ACME#.COM'

DB_DOMAIN = JAPAN.ACME\#.COM

Table 1-1 lists the special characters you can use in initialization parameter files.

\

Backslash

Escape character

If a special character must be treated literally in an initialization parameter file, then it must either be preceded by the backslash character, or the entire string containing the special character must be enclosed in quotation marks.

Using the Escape Character

As described in "Rules Governing Initialization Parameter Files", the backslash (\) can also signify a line continuation. If the backslash is followed by an alphanumeric character, then the backslash is treated as a normal character in the input. If it is not followed by an alphanumeric character, then the backslash is treated either as a backslash or as a continuation character.

Using Quotation Marks

Quotation marks can be nested in one of two ways. The first method is to double the quotation marks in the nested string. For example:

NLS_DATE_FORMAT = '''Today is'' MM/DD/YYYY'

The second method is to alternate single and double quotation marks. For example:

NLS_DATE_FORMAT = '"Today is" MM/DD/YYYY'

Changing Parameter Values in a Parameter File

You change the value of a parameter in a parameter file in one of the following ways:

- By editing an initialization parameter file
In most cases, the new value takes effect the next time you start an instance of the database.

- By issuing an ALTER SYSTEM SET ... SCOPE=SPFILE statement to update a server parameter file

- By issuing an ALTER SYSTEM RESET ... SCOPE=SPFILE statement to remove a parameter from a server parameter file, causing the default value to take effect the next time you start an instance of the database.

Modifiable Parameters

Some initialization parameters can be modified using the ALTER SESSION or ALTER SYSTEM statements while an instance is running. Use the following syntax to modify initialization parameters:

ALTER SESSION SET parameter_name = value
ALTER SYSTEM SET parameter_name = value [DEFERRED]

Whenever a parameter is modified using the ALTER SYSTEM statement, the Oracle Database records the statement that modifies the parameter in the alert log.

The ALTER SESSION statement changes the value of the specified parameter for the duration of the session that invokes the statement. The value of the parameter does not change for other sessions in the instance. The value of the following initialization parameters can be changed with ALTER SESSION:

The ALTER SYSTEM ... DEFERRED statement does not modify the global value of the parameter for existing sessions, but the value will be modified for future sessions that connect to the database. The value of the following initialization parameters can be changed with ALTER SYSTEM ... DEFERRED:

AUDIT_FILE_DEST
BACKUP_TAPE_IO_SLAVES

Displaying Current Parameter Values

To see the current settings for initialization parameters, use the following SQL*Plus command:

SQL> SHOW PARAMETERS

This command displays all parameters in alphabetical order, along with their current values.

Enter the following text string to display all parameters having BLOCK in their names:

SQL> SHOW PARAMETERS BLOCK

You can use the SPOOL command to write the output to a file.

Parameters You Should Not Specify in the Parameter File

You should not specify the following two types of parameters in your parameter files:

- Parameters that you never alter except when instructed to do so by Oracle to resolve a problem

- Derived parameters, which normally do not need altering because their values are calculated automatically by the Oracle database server

When Parameters Are Set Incorrectly

Some parameters have a minimum setting below which an Oracle instance will not start. For other parameters, setting the value too low or too high may cause Oracle to perform badly, but it will still run. Also, Oracle may convert some values outside the acceptable range to usable levels.

If a parameter value is too low or too high, or you have reached the maximum for some resource, then Oracle returns an error. Frequently, you can wait a short while and retry the operation when the system is not as busy. If a message occurs repeatedly, then you should shut down the instance, adjust the relevant parameter, and restart the instance.

Reading the Parameter Descriptions

The parameter descriptions in this chapter adhere to the following format.

PARAMETER_NAME

Property

Description

Parameter type

Specifies the type of the parameter:

- A Boolean parameter accepts either true or false as its value.

- A string parameter accepts any sequence of characters as its value, subject to the syntax for the parameter.

- An integer parameter accepts a 4-byte value that can range from 0 to 2^32 - 1.

- A parameter file parameter accepts an initialization parameter file specification as its value.

- A big integer parameter accepts an 8-byte value that can range from 0 to 2^64 - 1. You specify a value for a big integer as an integer together with an optional modifier such as K, M, or G, which respectively denotes kilobytes, megabytes, or gigabytes.
For example, 1000, 100 KB, 50 MB and 2 GB are valid specifications for big integers.

Syntax

For string and big integer parameters, specifies the valid syntax for specifying the parameter.

Default value

Specifies the value this parameter assumes if not explicitly specified.

Modifiable

Specifies whether the parameter can be changed for the current session (by an ALTER SESSION statement) or for all sessions in the current instance (by an ALTER SYSTEM statement):

- ALTER SESSION overrides the instance-wide setting of the parameter for the current session only. You can restore the instance-wide setting for that session only by issuing another ALTER SESSION statement.

- ALTER SYSTEM can be used to change the value in the server parameter file (SPFILE) of any initialization parameter. Such a change takes effect only in subsequent instances. The parameter descriptions indicate only those parameters that can be modified for the current instance.

Range of values

Specifies the valid range of values that this parameter can assume, shown as a minimum and maximum value. Not applicable to all parameters.

Oracle RAC

Specifies how the values for this parameter must be specified for multiple instances in an Oracle Real Application Clusters environment. Not applicable to all parameters.

For each parameter, paragraphs following these details further describe the parameter and the effects of different settings.

Initialization Parameter Descriptions

The remainder of this chapter describes the initialization parameters in alphabetical order. Initialization parameter values apply to the entire database, not to an individual user, unless otherwise specified.

Note:

Parameters that have become obsolete are not documented.

See Also:

- Oracle Database Upgrade Guide for information about obsolete parameters

- Your system release bulletins or other operating system-specific Oracle documentation

Press the "Next" button to go to the first initialization parameter.

ACTIVE_INSTANCE_COUNT

Property

Description

Parameter type

Integer

Default value

There is no default value.

Modifiable

No

Range of values

1 or >= the number of instances in the cluster. (Values other than 1 have no effect on the active or standby status of any instances.)

Basic

No

Oracle RAC

You must set this parameter for every instance, and multiple instances must have the same value.

Note:

The ACTIVE_INSTANCE_COUNT parameter is deprecated. It is retained for backward compatibility only.

ACTIVE_INSTANCE_COUNT enables you to designate one instance in a two-instance cluster as the primary instance and the other instance as the secondary instance. This parameter has no functionality in a cluster with more than two instances.

When you set this parameter to 1, the first instance you start up becomes the primary instance and accepts client connections. The second instance starts up as a secondary instance and can accept client connections only if the first instance fails. In such an event, the secondary instance becomes the primary instance.

When the failed instance can once again be started up, it starts up as the secondary instance, and will not accept client connections unless the current primary instance fails.

Note:

This parameter functions only in a cluster with only two instances.

See Also:

The Oracle Database Oracle Clusterware and Oracle Real Application Clusters Installation Guide for your operating system for more information on setting this parameter

AQ_TM_PROCESSES

Property

Description

Parameter type

Integer

Default value

1

Modifiable

ALTER SYSTEM

Range of values

0 to 40

Basic

No

AQ_TM_PROCESSES controls time monitoring on queue messages and controls processing of messages with delay and expiration properties specified.You do not need to specify a value for this parameter because Oracle Database automatically determines the number of processes and autotunes them, as necessary. Therefore, Oracle highly recommends that you leave the AQ_TM_PROCESSES parameter unspecified and let the system autotune.

The default value for AQ_TM_PROCESSES is used if the client does not explicitly set a value for the parameter in the init.ora file or using the ALTER SYSTEM command.

Note:

If you want to disable the Queue Monitor Coordinator, then you must set AQ_TM_PROCESSES to 0 in your parameter file. Oracle strongly recommends that you do NOT set AQ_TM_PROCESSES to 0. If you are using Oracle Streams, then setting this parameter to zero (which Oracle Database respects no matter what) can cause serious problems.

See Also:

Oracle Streams Advanced Queuing User's Guide for more information about this parameter and Advanced Queuing

ARCHIVE_LAG_TARGET

Property

Description

Parameter type

Integer

Default value

0 (disabled)

Modifiable

ALTER SYSTEM

Range of values

0 or any integer in [60, 7200]

Basic

No

Oracle RAC

Multiple instances should use the same value.

ARCHIVE_LAG_TARGET limits the amount of data that can be lost and effectively increases the availability of the standby database by forcing a log switch after the specified amount of time elapses.

A 0 value disables the time-based thread advance feature; otherwise, the value represents the number of seconds. Values larger than 7200 seconds are not of much use in maintaining a reasonable lag in the standby database. The typical, or recommended value is 1800 (30 minutes). Extremely low values can result in frequent log switches, which could degrade performance; such values can also make the archiver process too busy to archive the continuously generated logs.

See Also:

Oracle Data Guard Concepts and Administration for more information about criteria for setting this parameter

ASM_DISKGROUPS

Property

Description

Parameter type

String

Syntax

ASM_DISKGROUPS = diskgroup [, diskgroup ] ...

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Range of values

Comma-separated list of strings, up to 30 characters

Oracle RAC

Multiple instances can have different values.

Note:

This parameter may only be specified in an Automatic Storage Management instance.

ASM_DISKGROUPS specifies a list of names of disk groups to be mounted by an Automatic Storage Management instance at instance startup. Oracle ignores the value that you set for ASM_DISKGROUPS when you specify the NOMOUNT option at startup or when a ALTER DISKGROUP ALL MOUNT statement is issued.

Automatic Storage Management (ASM) automatically adds a disk group to this parameter when the disk group is successfully created or mounted, and automatically removes a disk group from this parameter when the disk group is dropped or dismounted.

Issuing the ALTER DISKGROUP...ALL MOUNT or ALTER DISKGROUP...ALL DISMOUNT command does not affect the value of this parameter.

ASM_DISKSTRING

Property

Description

Parameter type

String

Syntax

ASM_DISKSTRING = discovery_string [, discovery_string ] ...

Default value

The null string; Automatic Storage Management discovery finds all disks in an operating system-specific location to which the Automatic Storage Management instance has read/write access.

Modifiable

ALTER SYSTEM

Oracle RAC

Multiple instances can have different values. Different nodes might see the same disks under different names; however, each instance must be able to use its ASM_DISKSTRING to discover the same physical media as the other nodes in the cluster.

Note:

This parameter may only be specified in an Automatic Storage Management instance.

ASM_DISKSTRING specifies an operating system-dependent value used by Automatic Storage Management to limit the set of disks considered for discovery. When a new disk is added to a disk group, each Automatic Storage Management instance that has the disk group mounted must be able to discover the new disk using the value of ASM_DISKSTRING.

In most cases, the default value will be sufficient. Using a more restrictive value may reduce the time required for Automatic Storage Management to perform discovery, and thus improve disk group mount time or the time for adding a disk to a disk group. A "?" at the beginning of the string gets expanded to the Oracle home directory. Depending on the operating system, wildcard characters can be used. It may be necessary to dynamically change ASM_DISKSTRING before adding a disk so that the new disk will be discovered.

An attempt to dynamically modify ASM_DISKSTRING will be rejected and the old value retained if the new value cannot be used to discover a disk that is in a disk group that is already mounted.

ASM_POWER_LIMIT

Property

Description

Parameter type

Integer

Default value

1

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

0 to 11Foot 1

Oracle RAC

Multiple instances can have different values.

Footnote 1 Beginning with Oracle Database 11g Release 2 (11.2.0.2), if the COMPATIBLE.ASM disk group attribute is set to 11.2.0.2 or higher, then the range of values is 0 to 1024.

Note:

This parameter may only be specified in an Automatic Storage Management instance.

ASM_POWER_LIMIT specifies the maximum power on an Automatic Storage Management instance for disk rebalancing. The higher the limit, the faster rebalancing will complete. Lower values will take longer, but consume fewer processing and I/O resources.

If the POWER clause of a rebalance operation is not specified, then the default power will be the value of ASM_POWER_LIMIT.

ASM_PREFERRED_READ_FAILURE_GROUPS

Property

Description

Parameter type

String

Syntax

ASM_PREFERRED_READ_FAILURE_GROUPS = <diskgroup_name>.<failure_group_name>, ...

Default value

NULL

Modifiable

ALTER SYSTEM

Basic

No

Oracle RAC

The value is different on different nodes

ASM_PREFERRED_READ_FAILURE_GROUPS specifies the failure groups that contain preferred read disks. Preferred disks are instance specific. This parameter is only valid in ASM instances.

AUDIT_FILE_DEST

Property

Description

Parameter type

String

Syntax

AUDIT_FILE_DEST = 'directory'

Default value

The first default value is:
ORACLE_BASE/admin/ORACLE_SID/adump

The second default value, which is used if the first default value does not exist or is unusable, is:

ORACLE_HOME/rdbms/audit

Both of these default values are for Unix systems. Other platforms may have different defaults.

Modifiable

ALTER SYSTEM ... DEFERRED

Basic

No

AUDIT_FILE_DEST specifies the operating system directory into which the audit trail is written when the AUDIT_TRAIL initialization parameter is set to os, xml, or xml,extended. The audit records will be written in XML format if the AUDIT_TRAIL initialization parameter is set to xml or xml, extended. It is also the location to which mandatory auditing information is written and, if so specified by the AUDIT_SYS_OPERATIONS initialization parameter, audit records for user SYS.

AUDIT_SYS_OPERATIONS

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

Basic

No

AUDIT_SYS_OPERATIONS enables or disables the auditing of top-level operations, which are SQL statements directly issued by users when connecting with SYSDBA or SYSOPER privileges. (SQL statements run from within PL/SQL procedures or functions are not considered top-level.) The audit records are written to the operating system's audit trail. The audit records will be written in XML format if the AUDIT_TRAIL initialization parameter is set to xml or xml, extended.

On UNIX platforms, if the AUDIT_SYSLOG_LEVEL parameter has also been set, then it overrides the AUDIT_TRAIL parameter and SYS audit records are written to the system audit log using the SYSLOG utility.

AUDIT_SYSLOG_LEVEL

Property

Description

Parameter type

String

Syntax

AUDIT_SYSLOG_LEVEL = 'facility_clause.priority_clause'

facility_clause::=
{ USER | LOCAL[0 | 1 | 2 | 3 | 4 | 5 | 6 | 7] | SYSLOG | DAEMON | KERN | MAIL | AUTH | LPR | NEWS | UUCP | CRON }

priority_clause::=
{ NOTICE | INFO | DEBUG | WARNING | ERR | CRIT | ALERT | EMERG }

Default value

There is no default value.

Modifiable

No

Basic

No

Examples

AUDIT_SYSLOG_LEVEL = 'KERN.EMERG';
AUDIT_SYSLOG_LEVEL = 'LOCAL1.WARNING';

AUDIT_SYSLOG_LEVEL allows SYS and standard OS audit records to be written to the system audit log using the SYSLOG utility.

If you use this parameter, it is best to assign a file corresponding to every combination of facility and priority (especially KERN.EMERG) in syslog.conf . Sometimes these are assigned to print to the console in the default syslog.conf file. This can become annoying and will be useless as audit logs. Also, if you use this parameter, it is best to set the maximum length of syslog messages in the system to 512 bytes.

If AUDIT_SYSLOG_LEVEL is set and SYS auditing is enabled (AUDIT_SYS_OPERATIONS = TRUE), then SYS audit records are written to the system audit log.If AUDIT_SYSLOG_LEVEL is set and standard audit records are being sent to the operating system (AUDIT_TRAIL = os), then standard audit records are written to the system audit log.

Oracle Database Security Guide for more information about configuring the syslog audit trail by using the AUDIT_SYSLOG_LEVEL parameter

AUDIT_TRAIL

Property

Description

Parameter type

String

Syntax

AUDIT_TRAIL = { none | os | db [, extended] | xml [, extended] }

Default value

none

Modifiable

No

Basic

No

AUDIT_TRAIL enables or disables database auditing.

Values:

- none
Disables standard auditing. This value is the default if the AUDIT_TRAIL parameter was not set in the initialization parameter file or if you created the database using a method other than Database Configuration Assistant. If you created the database using Database Configuration Assistant, then the default is db.

- os
Directs all audit records to an operating system file. Oracle recommends that you use the os setting, particularly if you are using an ultra-secure database configuration.

- db
Directs audit records to the database audit trail (the SYS.AUD$ table), except for records that are always written to the operating system audit trail. Use this setting for a general database for manageability.

If the database was started in read-only mode with AUDIT_TRAIL set to db, then Oracle Database internally sets AUDIT_TRAIL to os. Check the alert log for details.

- db, extended
Performs all actions of AUDIT_TRAIL=db, and also populates the SQL bind and SQL text CLOB-type columns of the SYS.AUD$ table, when available. These two columns are populated only when this parameter is specified.

If the database was started in read-only mode with AUDIT_TRAIL set to db, extended, then Oracle Database internally sets AUDIT_TRAIL to os. Check the alert log for details.

- xml
Writes to the operating system audit record file in XML format. Records all elements of the AuditRecord node except Sql_Text and Sql_Bind to the operating system XML audit file.

- xml, extended
Performs all actions of AUDIT_TRAIL=xml, and populates the SQL bind and SQL text CLOB-type columns of the SYS.AUD$ table, wherever possible. These columns are populated only when this parameter is specified.

You can use the SQL AUDIT statement to set auditing options regardless of the setting of this parameter.

AWR_SNAPSHOT_TIME_OFFSET

Property

Description

Parameter type

Integer

Default value

There is no offset by default

Modifiable

ALTER SYSTEM

Range of values

0 - 3599, or the special value 1000000

Basic

No

Oracle RAC

Multiple instances should use the same value

AWR_SNAPSHOT_TIME_OFFSET specifies an offset for the AWR snapshot start time.

AWR snapshots normally start at the top of the hour (12:00, 1:00, 2:00, and so on). This parameter allows DBAs to specify an offset for the AWR snapshot start time.

This is a useful parameter to avoid CPU spikes from multiple instances all starting their AWR snapshots at the same time. If you have a large system with many instances on it (like many Exadata installations), and you are experiencing such CPU spikes, this parameter can be very useful.

The parameter is specified in seconds. Normally, you set it to a value less than 3600. If you set the special value 1000000 (1,000,000), you get an automatic mode, in which the offset is based on the database name.

The automatic mode is an effective way of getting a reasonable distribution of offset times when you have a very large number of instances running on the same node.

BACKGROUND_CORE_DUMP

Property

Description

Parameter type

String

Syntax

BACKGROUND_CORE_DUMP = { partial | full }

Default value

partial

Modifiable

No

Basic

No

BACKGROUND_CORE_DUMP specifies whether Oracle includes the SGA in the core file for Oracle background processes.

Values:

- partial
Oracle does not include the SGA in the core dump.

- full
Oracle includes the SGA in the core dump.

See Also:

"SHADOW_CORE_DUMP"

BACKGROUND_DUMP_DEST

Property

Description

Parameter type

String

Syntax

BACKGROUND_DUMP_DEST = { pathname | directory }

Default value

Operating system-dependent

Modifiable

ALTER SYSTEM

Range of values

Any valid local path, directory, or disk

Basic

No

BACKGROUND_DUMP_DEST specifies the pathname (directory or disc) where debugging trace files for the background processes (LGWR, DBWn, and so on) are written during Oracle operations.

An alert file in the directory specified by BACKGROUND_DUMP_DEST logs significant database events and messages. Anything that affects the database instance or global database is recorded here. The alert file is a normal text file. Its filename is operating system-dependent. For platforms that support multiple instances, it takes the form alert_sid.log, where sid is the system identifier. This file grows slowly, but without limit, so you might want to delete it periodically. You can delete the file even when the database is running.

Note:

This parameter is ignored by the new diagnosability infrastructure introduced in Oracle Database 11g Release 1, which places trace and core files in a location controlled by the DIAGNOSTIC_DEST initialization parameter.

See Also:

- Oracle Database Administrator's Guide for more information on setting this parameter and on alert files

- Your operating system-specific Oracle documentation for the default value of this parameter

- "USER_DUMP_DEST" for information on setting a destination for server process trace files

BACKUP_TAPE_IO_SLAVES

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SYSTEM ... DEFERRED

Range of values

true | false

Basic

No

BACKUP_TAPE_IO_SLAVES specifies whether I/O server processes (also called slaves) are used by Recovery Manager to back up, copy, or restore data to tape. When the value is set to true, Oracle uses an I/O server process to write to or read from a tape device. When the value is set to false (the default), Oracle does not use I/O server process for backups. Instead, the shadow process engaged in the backup accesses the tape device.

Note:

You cannot perform duplexed backups unless you enable this parameter. Otherwise, Oracle returns an error. When this parameter is enabled, Recovery Manager will configure as many server processes as needed for the number of backup copies requested.

See Also:

- Oracle Database Backup and Recovery User's Guide for more information on duplexed backups

- "DBWR_IO_SLAVES"

BITMAP_MERGE_AREA_SIZE

Property

Description

Parameter type

Integer

Default value

1048576 (1 MB)

Modifiable

No

Range of values

Operating system-dependent

Basic

No

Note:

Oracle does not recommend using the BITMAP_MERGE_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. BITMAP_MERGE_AREA_SIZE is retained for backward compatibility.

BITMAP_MERGE_AREA_SIZE is relevant only for systems containing bitmap indexes. It specifies the amount of memory Oracle uses to merge bitmaps retrieved from a range scan of the index. The default value is 1 MB. A larger value usually improves performance, because the bitmap segments must be sorted before being merged into a single bitmap.

See Also:

Oracle Database Performance Tuning Guide for more information on setting this parameter

BLANK_TRIMMING

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

Basic

No

BLANK_TRIMMING specifies the data assignment semantics of character datatypes.

Values:

- TRUE
Allows the data assignment of a source character string or variable to a destination character column or variable even though the source length is longer than the destination length. In this case, however, the additional length over the destination length must be all blanks, else an exception condition is raised. This value complies with the semantics of SQL-92 Transitional Level and above.

- FALSE
Disallows the data assignment if the source length is longer than the destination length and reverts to SQL92 Entry Level semantics.

CIRCUITS

Property

Description

Parameter type

Integer

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Basic

No

CIRCUITS specifies the total number of virtual circuits that are available for inbound and outbound network sessions. It is one of several parameters that contribute to the total SGA requirements of an instance.

You should not specify a value for this parameter unless you want to limit the number of virtual circuits.

CLIENT_RESULT_CACHE_LAG

Property

Description

Parameter type

Big integer

Syntax

CLIENT_RESULT_CACHE_LAG = integer [K | M | G]

Default value

3000

Modifiable

No

Range of values

0 to operating system-dependent

Basic

No

CLIENT_RESULT_CACHE_LAG specifies the maximum time (in milliseconds) since the last round trip to the server, before which the OCI client query execute makes a round trip to get any database changes related to the queries cached on the client.

See Also:

Oracle Call Interface Programmer's Guide for more information about the client query cache feature

CLIENT_RESULT_CACHE_SIZE

Property

Description

Parameter type

Big integer

Syntax

CLIENT_RESULT_CACHE_SIZE = integer [K | M | G]

Default value

0

Modifiable

No

Range of values

0 to operating system-dependent

Basic

No

CLIENT_RESULT_CACHE_SIZE specifies the maximum size of the client per-process result set cache (in bytes). All OCI client processes inherit this maximum size. Setting a nonzero value enables the client query cache feature. This can be overridden by the client configuration parameter OCI_RESULT_CACHE_MAX_SIZE.

See Also:

Oracle Call Interface Programmer's Guide for more information about the client query cache feature

CLUSTER_DATABASE

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

Basic

Yes

Oracle RAC

For all instances, the value must be set to true.

CLUSTER_DATABASE is an Oracle RAC parameter that specifies whether or not Oracle RAC is enabled.

See Also:

Oracle Real Application Clusters Administration and Deployment Guide

CLUSTER_DATABASE_INSTANCES

Property

Description

Parameter type

Integer

Default value

If CLUSTER_DATABASE is set to false, then 1
If CLUSTER_DATABASE is set to true:

- If ASM, then 4

- Otherwise, the number of configured Oracle RAC instances

Modifiable

No

Range of values

Any nonzero value

Basic

No

Oracle RAC

Multiple instances must have the same value.

CLUSTER_DATABASE_INSTANCES is an Oracle RAC parameter that specifies the number of instances that are configured as part of the cluster database. You must set this parameter for every instance. Normally you should set this parameter to the number of instances in your Oracle RAC environment. A proper setting for this parameter can improve memory use.

Oracle uses the value of this parameter to compute the default value of the LARGE_POOL_SIZE parameter when the PARALLEL_AUTOMATIC_TUNING parameter is set to true. Note that the PARALLEL_AUTOMATIC_TUNING parameter has been deprecated.

See Also:

- Oracle Database Performance Tuning Guide for more information on tuning parallel execution

CLUSTER_INTERCONNECTS

Property

Description

Parameter type

String

Syntax

CLUSTER_INTERCONNECTS = ifn [: ifn ] ...

Default value

There is no default value.

Modifiable

No

Range of values

One or more IP addresses, separated by colons

Basic

No

CLUSTER_INTERCONNECTS can be used in Oracle Real Application Clusters environments to indicate cluster interconnects available for use for the database traffic. Use this parameter if you need to override the default interconnect configured for the database traffic, which is stored in the cluster registry. This procedure also may be useful with Data Warehouse systems that have reduced availability requirements and high interconnect bandwidth demands.

CLUSTER_INTERCONNECTS specifically overrides the following:

- Network classifications stored by oifcfg in the OCR.

- The default interconnect chosen by Oracle.

If you want to load-balance the interconnect, then Oracle recommends that you use link-bonding at the operating system level, even if you have two databases on the same server, so that multiple interconnects use the same address. Note that multiple private addresses provide load balancing, but do not provide failover unless bonded. If you specify multiple addresses in init.ora using CLUSTER_INTERCONNECTS, instead of bonding multiple addresses at the operating system level, then typically availability is reduced, because each network interface card failure will take down that instance.

Refer to your vendor documentation for information about bonding interfaces. Some vendor bonding architectures may require the use of this parameter.

If you have multiple database instances on Oracle Real Application Clusters nodes and want to use a specific interface for each instance, then you can set the CLUSTER_INTERCONNECTS initialization parameter to the IP address for each database instance. For example:

hr1.init.ora.cluster_interconnects="192.0.2.111"
oltp3.init.ora.cluster_interconnects="192.0.2.112"

If the Oracle RAC interconnect is configured to run on a different interface than the Oracle Clusterware interconnect, then this configuration can cause reduced availability, as failovers or instance evictions can be delayed if the Oracle RAC interconnect fails while the Oracle Clusterware NIC remains up.

See Also:

Oracle Real Application Clusters Administration and Deployment Guide for additional platform-specific information about using CLUSTER_INTERCONNECTS

COMMIT_LOGGING

Property

Description

Parameter type

String

Syntax

COMMIT_LOGGING = { IMMEDIATE | BATCH }

Default value

There is no default value.

Modifiable

Yes (at both session-level and system-level)

Basic

No

Oracle RAC

Each instance may have its own setting

COMMIT_LOGGING is an advanced parameter used to control how redo is batched by Log Writer.

If COMMIT_LOGGING is altered after setting COMMIT_WAIT to FORCE_WAIT, then the FORCE_WAIT option is no longer valid.

COMMIT_POINT_STRENGTH

Property

Description

Parameter type

Integer

Default value

1

Modifiable

No

Range of values

0 to 255

Basic

No

COMMIT_POINT_STRENGTH is relevant only in distributed database systems. It specifies a value that determines the commit point site in a distributed transaction. The node in the transaction with the highest value for COMMIT_POINT_STRENGTH will be the commit point site.

The commit point site of a database should reflect the amount of critical shared data in the database. For example, a database on a mainframe computer typically shares more data among users than one on a personal computer. Therefore, COMMIT_POINT_STRENGTH should be set to a higher value for the mainframe computer.

The commit point site stores information about the status of transactions. Other computers in a distributed transaction require this information during Oracle's two-phase commit, so it is desirable to have machines that are always available as commit point sites. Therefore, set COMMIT_POINT_STRENGTH to a higher value on your more available machines.

See Also:

- Oracle Database Concepts and Oracle Database Administrator's Guide for information on two-phase commit

- Your operating system-specific Oracle documentation for the default value of this parameter

COMMIT_WAIT

Property

Description

Parameter type

String

Syntax

COMMIT_WAIT = { NOWAIT | WAIT | FORCE_WAIT }

Default value

There is no default value.

Modifiable

Yes (at both session-level and system-level)

Basic

No

Oracle RAC

Each instance may have its own setting

COMMIT_WAIT is an advanced parameter used to control when the redo for a commit is flushed to the redo logs.

Be aware that the NOWAIT option can cause a failure that occurs after the database receives the commit message, but before the redo log records are written. This can falsely indicate to a transaction that its changes are persistent. Also, it can violate the durability of ACID (Atomicity, Consistency, Isolation, Durability) transactions if the database shuts down unexpectedly.

If the parameter is set to FORCE_WAIT, the default behavior (immediate flushing of the redo log buffer with wait) is used. If this is a system setting, the session level and transaction level (COMMIT_WRITE) options will be ignored. If this is a session level setting, the transaction level options will be ignored. If COMMIT_WAIT is altered after it has been set to FORCE_WAIT, then the FORCE_WAIT option is no longer valid.

COMMIT_WRITE

Property

Description

Parameter type

String

Syntax

COMMIT_WRITE = '{IMMEDIATE | BATCH},{WAIT |NOWAIT}'

Default value

If this parameter is not explicitly specified, then database commit behavior defaults to writing commit records to disk before control is returned to the client.
If only IMMEDIATE or BATCH is specified, but not WAIT or NOWAIT, then WAIT mode is assumed.

If only WAIT or NOWAIT is specified, but not IMMEDIATE or BATCH, then IMMEDIATE mode is assumed.

Be aware that the NOWAIT option can cause a failure that occurs after the database receives the commit message, but before the redo log records are written. This can falsely indicate to a transaction that its changes are persistent. Also, it can violate the durability of ACID (Atomicity, Consistency, Isolation, Durability) transactions if the database shuts down unexpectedly.

Modifiable

Yes (at both session-level and system-level). Values supplied for COMMIT_WRITE in an ALTER SYSTEM or ALTER SESSION statement must be separated by a comma.

Range of values

Single-quoted, comma-separated list of either IMMEDIATE or BATCH, and either WAIT or NOWAIT.

Basic

No

Oracle RAC

Each instance may have its own setting

COMMIT_WRITE is an advanced parameter used to control how redo for transaction commits is written to the redo logs. The IMMEDIATE and BATCH options control how redo is batched by Log Writer. The WAIT and NOWAIT options control when the redo for a commit is flushed to the redo logs.

Note:

The COMMIT_WRITE parameter is deprecated. It is retained for backward compatibility only. It is replaced by the COMMIT_LOGGING and COMMIT_WAIT parameters.

COMPATIBLE

Property

Description

Parameter type

String

Syntax

COMPATIBLE = release_number

Default value

11.2.0

Modifiable

No

Range of values

10.0.0 to default release

Basic

Yes

Oracle RAC

Multiple instances must have the same value.

COMPATIBLE allows you to use a new release of Oracle, while at the same time guaranteeing backward compatibility with an earlier release. This is helpful if it becomes necessary to revert to the earlier release.

This parameter specifies the release with which Oracle must maintain compatibility. It allows you to take advantage of the maintenance improvements of a new release immediately in your production systems without testing the new functionality in your environment. Some features of the release may be restricted.

When using a standby database, this parameter must have the same value on both the primary and standby databases.

See Also:

Oracle Database Upgrade Guide for more information on setting this parameter

CONTROL_FILE_RECORD_KEEP_TIME

Property

Description

Parameter type

Integer

Default value

7 (days)

Modifiable

ALTER SYSTEM

Range of values

0 to 365 (days)

Basic

No

CONTROL_FILE_RECORD_KEEP_TIME specifies the minimum number of days before a reusable record in the control file can be reused. In the event a new record needs to be added to a reusable section and the oldest record has not aged enough, the record section expands. If this parameter is set to 0, then reusable sections never expand, and records are reused as needed.

If the number of reusable records in the control file exceeds the circular reuse record limit UB4MAXVAL, then reusable records will be overwritten even if CONTROL_FILE_RECORD_KEEP_TIME has not elapsed. UB4MAXVAL is defined in the oratypes.h header file, which is found in the public directory. Its value may vary according to the operating system you are using.

Note:

This parameter applies only to records in the control file that are circularly reusable (such as archive log records and various backup records). It does not apply to records such as datafile, tablespace, and redo thread records, which are never reused unless the corresponding object is dropped from the tablespace.

- "CONTROL_FILES"

- Oracle Database Backup and Recovery User's Guide

CONTROL_FILES

Property

Description

Parameter type

String

Syntax

CONTROL_FILES = filename [, filename ] ...
Note: The control file name can be an OMF (Oracle Managed Files) name. This occurs when the control file is re-created using the CREATE CONTROLFILE REUSE statement.

Default value

Operating system-dependent

Modifiable

No

Range of values

1 to 8 filenames

Basic

Yes

Oracle RAC

Multiple instances must have the same value.

Every database has a control file, which contains entries that describe the structure of the database (such as its name, the timestamp of its creation, and the names and locations of its datafiles and redo files). CONTROL_FILES specifies one or more names of control files, separated by commas.

Oracle recommends that you multiplex multiple control files on different devices or mirror the file at the operating system level.

- Oracle Database Performance Tuning Guide

- Oracle Database Administrator's Guide

CONTROL_MANAGEMENT_PACK_ACCESS

Property

Description

Parameter type

String

Syntax

CONTROL_MANAGEMENT_PACK_ACCESS = { NONE | DIAGNOSTIC | DIAGNOSTIC+TUNING }

Default value

Enterprise Edition: DIAGNOSTIC+TUNING
All other editions: NONE

Modifiable

ALTER SYSTEM

Basic

No

CONTROL_MANAGEMENT_PACK_ACCESS specifies which of the Server Manageability Packs should be active. The following packs are available:

- The DIAGNOSTIC pack includes AWR, ADDM, and so on.

- The TUNING pack includes SQL Tuning Advisor, SQLAccess Advisor, and so on.
A license for DIAGNOSTIC is required for enabling the TUNING pack.

Values:

- NONE
Both packs are not available.

- DIAGNOSTIC
Only the DIAGNOSTIC pack is available.

- DIAGNOSTIC+TUNING
Both packs are available. This is the default.

CORE_DUMP_DEST

Property

Description

Parameter type

String

Syntax

CORE_DUMP_DEST = directory

Default value

ORACLE_HOME/DBS

Modifiable

ALTER SYSTEM

Basic

No

CORE_DUMP_DEST is primarily a UNIX parameter and may not be supported on your platform. It specifies the directory where Oracle dumps core files.

CPU_COUNT

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0 to unlimited

Basic

No

CPU_COUNT specifies the number of CPUs available for Oracle Database to use. On core architectures, it specifies the number of available CPU cores. Various components of Oracle Database are configured based on the number of CPUs, such as the Optimizer, Parallel Query, and Resource Manager.

If CPU_COUNT is set to 0 (its default setting), then Oracle Database continuously monitors the number of CPUs reported by the operating system and uses the current count. If CPU_COUNT is set to a value other than 0, then Oracle Database will use this count rather than the actual number of CPUs, thus disabling dynamic CPU reconfiguration. When Resource Manager is enabled, setting CPU_COUNT limits the CPU utilization to approximately CPU_COUNT processors.

Note:

Setting CPU_COUNT to a value greater than the current number of CPUs results in an error. However, if CPU_COUNT is set to a value greater than the current number of CPUs in the initialization parameter file, then CPU_COUNT is capped to the current number of CPUs.

CREATE_BITMAP_AREA_SIZE

Property

Description

Parameter type

Integer

Default value

8388608 (8 MB)

Modifiable

No

Range of values

Operating system-dependent

Basic

No

Note:

Oracle does not recommend using the CREATE_BITMAP_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. CREATE_BITMAP_AREA_SIZE is retained for backward compatibility.

CREATE_BITMAP_AREA_SIZE is relevant only for systems containing bitmap indexes. It specifies the amount of memory (in bytes) allocated for bitmap creation. The default value is 8 MB. A larger value may speed up index creation.

Cardinality is the number of unique values in a column in relation to the number of rows in the table. If cardinality is very small, you can set a small value for this parameter. For example, if cardinality is only 2, then the value can be on the order of kilobytes rather than megabytes. As a general rule, the higher the cardinality, the more memory is needed for optimal performance.

See Also:

Oracle Database Performance Tuning Guide for more information on using bitmap indexes

CREATE_STORED_OUTLINES

Property

Description

Parameter type

String

Syntax

CREATE_STORED_OUTLINES = { true | false | category_name } [NOOVERRIDE]

Default value

There is no default value.

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

CREATE_STORED_OUTLINES determines whether Oracle automatically creates and stores an outline for each query submitted during the session.

Values:

- true
Enables automatic outline creation for subsequent queries in the same session. These outlines receive a unique system-generated name and are stored in the DEFAULT category. If a particular query already has an outline defined for it in the DEFAULT category, then that outline will remain and a new outline will not be created.

- false
Disables automatic outline creation during the session. This is the default.

- category_name
Enables the same behavior as true except that any outline created during the session is stored in the category_name category.

- NOOVERRIDE
NOOVERRIDE specifies that this system setting will not override the setting for any session in which this parameter was explicitly set. If you do not specify NOOVERRIDE, then this setting takes effect in all sessions.

See Also:

Oracle Database Performance Tuning Guide for more information on setting this parameter

CURSOR_BIND_CAPTURE_DESTINATION

Property

Description

Parameter type

String

Syntax

CURSOR_BIND_CAPTURE_DESTINATION = { off | memory | memory+disk }

Default value

memory+disk

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

CURSOR_BIND_CAPTURE_DESTINATION determines the location at which bind variables that are captured from SQL cursors are available.

Values:

- off
Bind variables are not captured from SQL cursors.

- memory
Bind variables are captured from SQL cursors, and are available only in memory (V$ views).

- memory+disk
Bind variables are captured from SQL cursors, and are available in memory (V$ views) and disk (Automatic Workload Repository tables, SQL Tuning Set tables, and so on).

Note:

The CURSOR_BIND_CAPTURE_DESTINATION initialization parameter is available starting with Oracle Database 11g Release 2 (11.2.0.2).

CURSOR_SHARING

Property

Description

Parameter type

String

Syntax

CURSOR_SHARING = { SIMILAR | EXACT | FORCE }

Default value

EXACT

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

CURSOR_SHARING determines what kind of SQL statements can share the same cursors.

Values:

- FORCE
Allows the creation of a new cursor if sharing an existing cursor, or if the cursor plan is not optimal.

- SIMILAR
Causes statements that may differ in some literals, but are otherwise identical, to share a cursor, unless the literals affect either the meaning of the statement or the degree to which the plan is optimized.

- EXACT
Only allows statements with identical text to share the same cursor.

Notes:

- If you set CURSOR_SHARING, then Oracle recommends the FORCE setting unless you are in a DSS environment. FORCE limits the growth of child cursors that can occur when the setting is SIMILAR.

- The value of the CURSOR_SHARING parameter has performance implications. Refer to Oracle Database Performance Tuning Guide before setting this parameter.

CURSOR_SPACE_FOR_TIME

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

Basic

No

Note:

The CURSOR_SPACE_FOR_TIME parameter is deprecated. It is retained for backward compatibility only.

CURSOR_SPACE_FOR_TIME lets you use more space for cursors in order to save time. It affects both the shared SQL area and the client's private SQL area.

Most users will not need to set this parameter because of the significantly enhanced concurrency modifications introduced in Oracle Database 10g Release 2 (10.2.0.2) and later.

Values:

- true
Shared SQL areas are kept pinned in the shared pool. As a result, shared SQL areas are not aged out of the pool as long as an open cursor references them. Because each active cursor's SQL area is present in memory, execution is faster. However, the shared SQL areas never leave memory while they are in use. Therefore, you should set this parameter to true only when the shared pool is large enough to hold all open cursors simultaneously.

In addition, a setting of true retains the private SQL area allocated for each cursor between executions instead of discarding it after cursor execution, saving cursor allocation and initialization time.

- false
Shared SQL areas can be deallocated from the library cache to make room for new SQL statements.

Note:

If this parameter is set to true, then the SERIAL_REUSE parameter is disabled.

See Also:

- Oracle Database Concepts and Oracle Database Performance Tuning Guide

- "SERIAL_REUSE"

DB_nK_CACHE_SIZE

Property

Description

Parameter type

Big integer

Syntax

DB_[2 | 4 | 8 | 16 | 32]K_CACHE_SIZE = integer [K | M | G]

Default value

0 (additional block size caches are not configured by default)

Modifiable

ALTER SYSTEM

Range of values

Minimum: 0 (values greater than zero are automatically modified to be either the granule size * number of processor groups, or 4 MB * number of CPUs, whichever is greater)
Maximum: operating system-dependent

Basic

No

DB_nK_CACHE_SIZE (where n = 2, 4, 8, 16, 32) specifies the size of the cache for the nK buffers. You can set this parameter only when DB_BLOCK_SIZE has a value other than nK. For example, if DB_BLOCK_SIZE=4096, then it is illegal to specify the parameter DB_4K_CACHE_SIZE (because the size for the 4 KB block cache is already specified by DB_CACHE_SIZE).

Do not set this parameter to zero if there are any online tablespaces with an nK block size.

Operating system-specific block size restrictions apply. For example, you cannot set DB_32K_CACHE_SIZE if the operating system's maximum block size is less than 32 KB. Also, you cannot set DB_2K_CACHE_SIZE if the minimum block size is greater than 2 KB.

See Also:

Your operating system-specific Oracle documentation for more information on block size restrictions

DB_BLOCK_BUFFERS

Property

Description

Parameter type

Integer

Default value

0

Modifiable

No

Range of values

50 to an operating system-specific maximum

Basic

No

Oracle RAC

Multiple instances can have different values, and you can change the values as needed.

Note:

DB_BLOCK_BUFFERS cannot be combined with the dynamic DB_CACHE_SIZE parameter; combining these parameters in the same parameter file will produce an error.

DB_BLOCK_BUFFERS specifies the number of database buffers in the buffer cache. It is one of several parameters that contribute to the total memory requirements of the SGA of an instance.

This parameter, together with DB_BLOCK_SIZE, determines the total size of the buffer cache. Effective use of the buffer cache can greatly reduce the I/O load on the database. DB_BLOCK_SIZE can be specified only when the database is first created, so you use DB_BLOCK_BUFFERS to control the size of the buffer cache.

DB_BLOCK_CHECKING

Property

Description

Parameter type

String

Syntax

DB_BLOCK_CHECKING = { FALSE | OFF | LOW | MEDIUM | TRUE | FULL }

Default value

FALSE

Modifiable

ALTER SYSTEM

Basic

No

DB_BLOCK_CHECKING specifies whether or not Oracle performs block checking for database blocks.

Values:

- OFF or FALSE
No block checking is performed for blocks in user tablespaces. However, semantic block checking for SYSTEM tablespace blocks is always turned on.

- LOW
Basic block header checks are performed after block contents change in memory (for example, after UPDATE or INSERT statements, on-disk reads, or inter-instance block transfers in Oracle RAC).

- MEDIUM
All LOW checks and full semantic checks are performed for all objects except indexes (whose contents can be reconstructed by a drop+rebuild on encountering a corruption).

- FULL or TRUE
All LOW and MEDIUM checks and full semantic checks are performed for all objects.

Oracle checks a block by going through the data in the block, making sure it is logically self-consistent. Block checking can often prevent memory and data corruption. Block checking typically causes 1% to 10% overhead, depending on workload and the parameter value. The more updates or inserts in a workload, the more expensive it is to turn on block checking. You should set DB_BLOCK_CHECKING to FULL if the performance overhead is acceptable.

For backward compatibility, the use of FALSE (implying OFF) and TRUE (implying FULL) is preserved.

DB_BLOCK_CHECKSUM

Property

Description

Parameter type

String

Syntax

DB_BLOCK_CHECKSUM = { OFF | FALSE | TYPICAL | TRUE | FULL }

Default value

TYPICAL

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

DB_BLOCK_CHECKSUM determines whether DBWn and the direct loader will calculate a checksum (a number calculated from all the bytes stored in the block) and store it in the cache header of every data block when writing it to disk. Checksums are verified when a block is read - only if this parameter is TYPICAL or FULL and the last write of the block stored a checksum. In FULL mode, Oracle also verifies the checksum before a change application from update/delete statements and recomputes it after the change is applied. In addition, Oracle gives every log block a checksum before writing it to the current log.

Starting with Oracle Database 11g, most of the log block checksum is done by the generating foreground processes, while the LGWR performs the rest of the work, for better CPU and cache efficiency. Prior to Oracle Database 11g, the LGWR solely performed the log block checksum. When this parameter is set to FULL, the LGWR verifies the checksum of each log block generated by the foreground processes before writing it to disk.

If this parameter is set to OFF, DBWn calculates checksums only for the SYSTEM tablespace, but not for user tablespaces. In addition, no log checksum is performed when this parameter is set to OFF.

Checksums allow Oracle to detect corruption caused by underlying disks, storage systems, or I/O systems. If set to FULL, DB_BLOCK_CHECKSUM also catches in-memory corruptions and stops them from making it to the disk. Turning on this feature in TYPICAL mode causes only an additional 1% to 2% overhead. In the FULL mode it causes 4% to 5% overhead. Oracle recommends that you set DB_BLOCK_CHECKSUM to TYPICAL.

For backward compatibility the use of TRUE (implying TYPICAL) and FALSE (implying OFF) values is preserved.

DB_BLOCK_SIZE

Property

Description

Parameter type

Integer

Default value

8192

Modifiable

No

Range of values

2048 to 32768, but your operating system may have a narrower range

Basic

Yes

Oracle RAC

You must set this parameter for every instance, and multiple instances must have the same value.

Caution:

Set this parameter at the time of database creation. Do not alter it afterward.

DB_BLOCK_SIZE specifies (in bytes) the size of Oracle database blocks. Typical values are 4096 and 8192. The value of this parameter must be a multiple of the physical block size at the device level.

The value for DB_BLOCK_SIZE in effect at the time you create the database determines the size of the blocks. The value must remain set to its initial value.

For Real Application Clusters, this parameter affects the maximum value of the FREELISTS storage parameter for tables and indexes. Oracle uses one database block for each freelist group. Decision support system (DSS) and data warehouse database environments tend to benefit from larger block size values.

Note:

- 32-bit operating systems support a maximum DB_BLOCK_SIZE value of 16384

- 64-bit operating systems support a maximum DB_BLOCK_SIZE value of 32768

DB_CACHE_ADVICE

Property

Description

Parameter type

String

Syntax

DB_CACHE_ADVICE = { ON | READY | OFF }

Default value

If STATISTICS_LEVEL is set to TYPICAL or ALL, then ON
If STATISTICS_LEVEL is set to BASIC, then OFF

Modifiable

ALTER SYSTEM

Basic

No

DB_CACHE_ADVICE enables or disables statistics gathering used for predicting behavior with different cache sizes through the V$DB_CACHE_ADVICE performance view.

Values:

- OFF
Advisory is turned off and the memory for the advisory is not allocated.

- READY
Advisory is turned off but the memory for the advisory remains allocated. Allocating the memory before the advisory is actually turned on avoids the risk of an error when you switch the parameter to ON.

If the parameter is switched to this state from ON, the contents of the view are preserved and the memory for the advisory is retained.

If the parameter is switched to this state from OFF, you may get an error.

- ON
Advisory is turned on. CPU and memory overheads are incurred. Attempting to set the parameter to this state when it is already in the OFF state may result in an error. Otherwise, the view (V$DB_CACHE_ADVICE) is reset and statistics are gathered to the newly refreshed view.

If the parameter is in the READY state, you can set it to ON without any errors because the memory is already allocated. The view is reset and statistics are displayed in the newly refreshed view.

DB_CACHE_SIZE

Property

Description

Parameter type

Big integer

Syntax

DB_CACHE_SIZE = integer [K | M | G]

Default value

If SGA_TARGET is set: If the parameter is not specified, then the default is 0 (internally determined by the Oracle Database). If the parameter is specified, then the user-specified value indicates a minimum value for the memory pool.
If SGA_TARGET is not set, then the default is either 48 MB or 4 MB * number of CPUs, whichever is greater

Modifiable

ALTER SYSTEM

Basic

No

DB_CACHE_SIZE specifies the size of the DEFAULT buffer pool for buffers with the primary block size (the block size defined by the DB_BLOCK_SIZE initialization parameter).

The value must be at least 4M * number of cpus (smaller values are automatically rounded up to this value). A user-specified value larger than this is rounded up to the nearest granule size. A value of zero is illegal because it is needed for the DEFAULT memory pool of the primary block size, which is the block size for the SYSTEM tablespace.

Oracle Database Performance Tuning Guide and Oracle Database Administrator's Guide for more information on setting this parameter

DB_CREATE_FILE_DEST

Property

Description

Parameter type

String

Syntax

DB_CREATE_FILE_DEST = directory | disk group

Default value

There is no default value.

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

Yes

DB_CREATE_FILE_DEST specifies the default location for Oracle-managed datafiles. This location is also used as the default location for Oracle-managed control files and online redo logs if none of the DB_CREATE_ONLINE_LOG_DEST_n initialization parameters are specified.

If a file system directory is specified as the default location, then the directory must already exist; Oracle does not create it. The directory must have appropriate permissions that allow Oracle to create files in it. Oracle generates unique names for the files, and a file thus created is an Oracle Managed File.

See Also:

Oracle Database Administrator's Guide for more information on setting this parameter and on Oracle Managed Files

DB_CREATE_ONLINE_LOG_DEST_n

Property

Description

Parameter type

String

Syntax

DB_CREATE_ONLINE_LOG_DEST_[1 | 2 | 3 | 4 | 5] = directory | disk group

Default value

There is no default value.

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

Yes

DB_CREATE_ONLINE_LOG_DEST_n (where n = 1, 2, 3, ... 5) specifies the default location for Oracle-managed control files and online redo logs. If more than one DB_CREATE_ONLINE_LOG_DEST_n parameter is specified, then the control file or online redo log is multiplexed across the locations of the other DB_CREATE_ONLINE_LOG_DEST_n parameters. One member of each online redo log is created in each location, and one control file is created in each location.

Specifying at least two parameters provides greater fault tolerance for the control files and online redo logs if one of the locations should fail.

If a file system directory is specified as the default location, then the directory must already exist; Oracle does not create it. The directory must have appropriate permissions that allow Oracle to create files in it. Oracle generates unique names for the files, and a file thus created is an Oracle Managed File.

See Also:

Oracle Database Administrator's Guide for more information on setting this parameter and on Oracle Managed Files

DB_DOMAIN

Property

Description

Parameter type

String

Syntax

DB_DOMAIN = domain_name

Default value

There is no default value.

Modifiable

No

Range of values

Any legal string of name components, separated by periods and up to 128 characters long (including the periods).

Basic

Yes

Oracle RAC

You must set this parameter for every instance, and multiple instances must have the same value.

In a distributed database system, DB_DOMAIN specifies the logical location of the database within the network structure. You should set this parameter if this database is or ever will be part of a distributed system. The value consists of the extension components of a global database name, consisting of valid identifiers (any alphanumeric ASCII characters), separated by periods.

Note:

Oracle recommends that you specify DB_DOMAIN as a unique string for all databases in a domain.

This parameter allows one department to create a database without worrying that it might have the same name as a database created by another department. If one sales department's DB_DOMAIN is JAPAN.ACME.COM, then their SALES database (SALES.JAPAN.ACME.COM) is uniquely distinguished from another database with DB_NAME = SALES but with DB_DOMAIN = US.ACME.COM.

If you omit the domains from the name of a database link, Oracle expands the name by qualifying the database with the domain of your local database as it currently exists in the data dictionary, and then stores the link name in the data dictionary. The characters valid in a database domain name are: alphanumeric characters, underscore (_), and number sign (#).

DB_FILE_MULTIBLOCK_READ_COUNT

Property

Description

Parameter type

Integer

Default value

The default value corresponds to the maximum I/O size that can be efficiently performed and is platform-dependent

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

Operating system-dependent

Basic

No

DB_FILE_MULTIBLOCK_READ_COUNT is one of the parameters you can use to minimize I/O during table scans. It specifies the maximum number of blocks read in one I/O operation during a sequential scan. The total number of I/Os needed to perform a full table scan depends on such factors as the size of the table, the multiblock read count, and whether parallel execution is being utilized for the operation.

As of Oracle Database 10g release 2, the default value of this parameter is a value that corresponds to the maximum I/O size that can be performed efficiently. This value is platform-dependent and is 1MB for most platforms.Because the parameter is expressed in blocks, it will be set to a value that is equal to the maximum I/O size that can be performed efficiently divided by the standard block size. Note that if the number of sessions is extremely large the multiblock read count value is decreased to avoid the buffer cache getting flooded with too many table scan buffers.

Even though the default value may be a large value, the optimizer will not favor large plans if you do not set this parameter. It would do so only if you explicitly set this parameter to a large value.

Online transaction processing (OLTP) and batch environments typically have values in the range of 4 to 16 for this parameter. DSS and data warehouse environments tend to benefit most from maximizing the value of this parameter. The optimizer is more likely to choose a full table scan over an index if the value of this parameter is high.

The maximum value is the operating system's maximum I/O size expressed as Oracle blocks ((max I/O size)/DB_BLOCK_SIZE). If you set this parameter to a value greater than the maximum, Oracle uses the maximum.

- Oracle Database Performance Tuning Guide for more information on setting this parameter

DB_FILE_NAME_CONVERT

Property

Description

Parameter type

String

Syntax

DB_FILE_NAME_CONVERT = 'string1' , 'string2' , 'string3' , 'string4' , ...
Where:

- string1 is the pattern of the primary database filename

- string2 is the pattern of the standby database filename

- string3 is the pattern of the primary database filename

- string4 is the pattern of the standby database filename

You can use as many pairs of primary and standby replacement strings as required. You can use single or double quotation marks.

The following are example settings that are acceptable:

DB_FILE_NAME_CONVERT = '/dbs/t1/','/dbs/t1/s','dbs/t2/ ','dbs/t2/s_'

Default value

There is no default value.

Modifiable

ALTER SESSION

Basic

No

DB_FILE_NAME_CONVERT is useful for creating a duplicate database for recovery purposes. It converts the filename of a new datafile on the primary database to a filename on the standby database. If you add a datafile to the primary database, you must add a corresponding file to the standby database. When the standby database is updated, this parameter converts the datafile name on the primary database to the datafile name on the standby database. The file on the standby database must exist and be writable, or the recovery process will halt with an error.

If you specify an odd number of strings (the last string has no corresponding replacement string), an error is signalled during startup. If the filename being converted matches more than one pattern in the pattern/replace string list, the first matched pattern takes effect. There is no limit on the number of pairs that you can specify in this parameter (other than the hard limit of the maximum length of multivalue parameters).

Set the value of this parameter to two strings. The first string is the pattern found in the datafile names on the primary database. The second string is the pattern found in the datafile names on the standby database.

You can also use DB_FILE_NAME_CONVERT to rename the datafiles in the clone control file when setting up a clone database during tablespace point-in-time recovery.

DB_FILES

Property

Description

Parameter type

Integer

Default value

200

Modifiable

No

Range of values

Minimum: the largest among the absolute file numbers of the datafiles in the database
Maximum: operating system-dependent

Basic

No

Oracle RAC

Multiple instances must have the same value.

DB_FILES specifies the maximum number of database files that can be opened for this database. The maximum valid value is the maximum number of files, subject to operating system constraint, that will ever be specified for the database, including files to be added by ADD DATAFILE statements.

If you increase the value of DB_FILES, then you must shut down and restart all instances accessing the database before the new value can take effect. If you have a primary and standby database, then they should have the same value for this parameter.

DB_FLASH_CACHE_FILE

Property

Description

Parameter type

String

Syntax

DB_FLASH_CACHE_FILE = filename | disk group

Default value

There is no default value.

Modifiable

No

Basic

No

DB_FLASH_CACHE_FILE filename for the flash memory or disk group representing a collection of flash memory.

Specifying this parameter without also specifying the DB_FLASH_CACHE_SIZE initialization parameter is not allowed.

See Also:

"DB_FLASH_CACHE_SIZE"

DB_FLASH_CACHE_SIZE

Property

Description

Parameter type

Big integer

Syntax

DB_FLASH_CACHE_SIZE = integer [K | M | G]

Default value

0

Modifiable

ALTER SYSTEM

Range of values

Minimum: 0
Maximum: operating system-dependent

Basic

No

DB_FLASH_CACHE_SIZE specifies the size of the Database Smart Flash Cache (flash cache). This parameter may only be specified at instance startup. You can dynamically change this parameter to 0 (disabling the flash cache) after the database is started. You can re-enable flash cache by setting this parameter to the original value when the database was started. Dynamic resizing of DB_FLASH_CACHE_SIZE or re-enabling flash cache to a different size is not supported.

See Also:

"DB_FLASH_CACHE_FILE"

DB_FLASHBACK_RETENTION_TARGET

Property

Description

Parameter type

Integer

Default value

1440 (minutes)

Modifiable

ALTER SYSTEM ... SID='*'

Range of values

0 to 2^31 - 1

Basic

No

DB_FLASHBACK_RETENTION_TARGET specifies the upper limit (in minutes) on how far back in time the database may be flashed back. How far back one can flashback a database depends on how much flashback data Oracle has kept in the fast recovery area.

DB_KEEP_CACHE_SIZE

Property

Description

Parameter type

Big integer

Syntax

DB_KEEP_CACHE_SIZE = integer [K | M | G]

Default value

0 (DB_KEEP_CACHE_SIZE is not configured by default)

Modifiable

ALTER SYSTEM

Range of values

Minimum: 0 (values greater than zero are automatically modified to be either the granule size * number of processor groups, or 4 MB * number of CPUs, whichever is greater)
Maximum: operating system-dependent

Basic

No

DB_KEEP_CACHE_SIZE specifies the size of the KEEP buffer pool. The size of the buffers in the KEEP buffer pool is the primary block size (the block size defined by the DB_BLOCK_SIZE initialization parameter).

See Also:

- "DB_RECYCLE_CACHE_SIZE"

- Oracle Database Performance Tuning Guide for information on setting these parameters and on using multiple buffer pools

DB_LOST_WRITE_PROTECT

Property

Description

Parameter type

String

Syntax

DB_LOST_WRITE_PROTECT = { NONE | TYPICAL | FULL }

Default value

NONE

Modifiable

ALTER SYSTEM

Basic

No

Oracle RAC

In Oracle RAC instances, the parameter value is system-wide.

DB_LOST_WRITE_PROTECT enables or disables lost write detection. A data block lost write occurs when an I/O subsystem acknowledges the completion of the block write, while in fact the write did not occur in the persistent storage.

When the parameter is set to TYPICAL on the primary database, the instance logs buffer cache reads for read-write tablespaces in the redo log, which is necessary for detection of lost writes.

When the parameter is set to FULL on the primary database, the instance logs reads for read-only tablespaces as well as read-write tablespaces.

When the parameter is set to TYPICAL or FULL on the standby database or on the primary database during media recovery, the instance performs lost write detection.

When the parameter is set to NONE on either the primary database or the standby database, no lost write detection functionality is enabled.

DB_NAME

Property

Description

Parameter type

String

Syntax

DB_NAME = database_name

Default value

There is no default value.

Modifiable

No

Basic

Yes

Oracle RAC

You must set this parameter for every instance. Multiple instances must have the same value, or the same value must be specified in the STARTUP OPEN SQL*Plus command or the ALTER DATABASE MOUNT SQL statement.

DB_NAME specifies a database identifier of up to 8 characters. This parameter must be specified and must correspond to the name specified in the CREATE DATABASE statement.

If you have multiple databases, the value of this parameter should match the Oracle instance identifier of each one to avoid confusion with other databases running on the system. The value of DB_NAME should be the same in both the standby and production initialization parameter files.

The database name specified in either the STARTUP command or the ALTER DATABASE ... MOUNT statement for each instance of the cluster database must correspond to the DB_NAME initialization parameter setting.

The following characters are valid in a database name: alphanumeric characters, underscore (_), number sign (#), and dollar sign ($). No other characters are valid. Oracle removes double quotation marks before processing the database name. Therefore you cannot use double quotation marks to embed other characters in the name. The database name is case insensitive.

DB_RECOVERY_FILE_DEST

Property

Description

Parameter type

String

Syntax

DB_RECOVERY_FILE_DEST = directory | disk group

Default value

There is no default value.

Modifiable

ALTER SYSTEM ... SID='*'

Basic

Yes

Oracle RAC

You must set this parameter for every instance, and multiple instances must have the same value.

DB_RECOVERY_FILE_DEST specifies the default location for the fast recovery area. The fast recovery area contains multiplexed copies of current control files and online redo logs, as well as archived redo logs, flashback logs, and RMAN backups.

Specifying this parameter without also specifying the DB_RECOVERY_FILE_DEST_SIZE initialization parameter is not allowed.

Parameter type

Big integer

Syntax

DB_RECYCLE_CACHE_SIZE = integer [K | M | G]

Default value

0 (DB_RECYCLE_CACHE_SIZE is not configured by default)

Modifiable

ALTER SYSTEM

Range of values

Minimum: 0 (values greater than zero are automatically modified to be either the granule size * number of processor groups, or 4 MB * number of CPUs, whichever is greater)
Maximum: operating system-dependent

Basic

No

DB_RECYCLE_CACHE_SIZE specifies the size of the RECYCLE buffer pool. The size of the buffers in the RECYCLE pool is the primary block size (the block size defined by the DB_BLOCK_SIZE initialization parameter).

See Also:

- "DB_KEEP_CACHE_SIZE"

- Oracle Database Performance Tuning Guide for information on setting these parameters and on using multiple buffer pools

DB_SECUREFILE

Property

Description

Parameter type

String

Syntax

DB_SECUREFILE = { NEVER | PERMITTED | ALWAYS | IGNORE }

Default value

PERMITTED

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

DB_SECUREFILE specifies whether or not to treat LOB files as SecureFiles.

Values:

- NEVER
Any LOBs that are specified as SecureFiles are created as BasicFile LOBs. All SecureFile-specific storage options and features (for example, compress, encrypt, deduplicate) will cause an exception. The BasicFile LOB defaults will be used for storage options not specified.

- PERMITTED
LOBs are allowed to be created as SecureFiles.

- ALWAYS
Attempts to create all LOBs as SecureFile LOBs but creates any LOBs not in an Automatic Segment Space Managed tablespace as BasicFile LOBs, unless SECUREFILE is explicitly specified. Any BasicFile LOB storage options that are specified will be ignored and the SecureFile defaults will be used for all storage options not specified.

- IGNORE
The SECUREFILE keyword and all SecureFile options are ignored.

If the COMPATIBLE initialization parameter is not set to 11.1.0 or higher, then LOBs are not treated as SecureFiles.

If there is a LOB column with two partitions (one that has a tablespace for which ASSM is enabled and one that has a tablespace for which ASSM is not enabled), then LOBs in the partition with the ASSM-enabled tablespace will be treated as SecureFiles and LOBs in the other partition will be treated as BasicFile LOBs.

DB_ULTRA_SAFE

Property

Description

Parameter type

String

Syntax

DB_ULTRA_SAFE = { OFF | DATA_ONLY | DATA_AND_INDEX }

Default value

DB_UNIQUE_NAME

Property

Description

Parameter type

String

Syntax

DB_UNIQUE_NAME = database_unique_name

Default value

Database instances: the value of DB_NAME
Automatic Storage Management instances: +ASM

Modifiable

No

Basic

Yes

Oracle RAC

Multiple instances must have the same value.

DB_UNIQUE_NAME specifies a globally unique name for the database. Databases with the same DB_NAME within the same DB_DOMAIN (for example, copies of a database created for reporting or a physical standby) must have a unique DB_UNIQUE_NAME. Every database's DB_UNIQUE_NAME must be unique within the enterprise.

The value of DB_UNIQUE_NAME can be up to 30 characters and is case insensitive. The following characters are valid in a database name: alphanumeric characters, underscore (_), number sign (#), and dollar sign ($).

DB_UNRECOVERABLE_SCN_TRACKING

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

Oracle RAC

Multiple instances must have the same value

DB_UNRECOVERABLE_SCN_TRACKING enables or disables the tracking of unrecoverable (NOLOGGING) direct-path insert and load operations.

When the value is set to true, updates are made to the controlfile that maintains the V$DATAFILE.UNRECOVERABLE_CHANGE# and V$DATAFILE.UNRECOVERABLE_TIME columns. When the value is set to false, updates are not made to the controlfile. Setting this parameter to false may improve performance of direct-path NOLOGGING operations.

Note:

The DB_UNRECOVERABLE_SCN_TRACKING initialization parameter is available starting with Oracle Database 11g Release 2 (11.2.0.2).

DB_WRITER_PROCESSES

Property

Description

Parameter type

Integer

Default value

1 or CPU_COUNT / 8, whichever is greater. If the number of processor groups is less than 36 but greater than the number of DB writer processes, then the number of DB writer processes is adjusted to be a multiple of the number of processor groups. If the number of DB writer processes is greater than or equal to the number of processor groups, then there is no adjustment.

Modifiable

No

Range of values

1 to 36

Basic

No

DB_WRITER_PROCESSES specifies the initial number of database writer processes (DBW0, ... DBW9 and DBWa, ... DBWz) for an instance. This parameter is useful for systems that modify data heavily.

See Also:

- Oracle Database Concepts for more information on the database writer processes

- Oracle Database Performance Tuning Guide for information on setting this parameter

DBWR_IO_SLAVES

Property

Description

Parameter type

Integer

Default value

0

Modifiable

No

Range of values

0 to operating system-dependent

Basic

No

DBWR_IO_SLAVES is relevant only on systems with only one database writer process (DBW0). It specifies the number of I/O server processes used by the DBW0 process. The DBW0 process and its server processes always write to disk. By default, the value is 0 and I/O server processes are not used.

If you set DBWR_IO_SLAVES to a nonzero value, the number of I/O server processes used by the ARCH and LGWR processes is set to 4. However, the number of I/O server processes used by Recovery Manager is set to 4 only if asynchronous I/O is disabled (either your platform does not support asynchronous I/O or disk_asynch_io is set to false).

Typically, I/O server processes are used to simulate asynchronous I/O on platforms that do not support asynchronous I/O or that implement it inefficiently. However, you can use I/O server processes even when asynchronous I/O is being used. In that case the I/O server processes will use asynchronous I/O.

I/O server processes are also useful in database environments with very large I/O throughput, even if asynchronous I/O is enabled.

"BACKUP_TAPE_IO_SLAVES"

DDL_LOCK_TIMEOUT

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SESSION

Range of values

0 to 1,000,000 (in seconds)

Basic

No

DDL_LOCK_TIMEOUT specifies a time limit for how long DDL statements will wait in a DML lock queue. The default value of zero indicates a status of NOWAIT. The maximum value of 1,000,000 seconds will result in the DDL statement waiting forever to acquire a DML lock.

If a lock is not acquired before the timeout period expires, then an error is returned.

DEFERRED_SEGMENT_CREATION

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

DEFERRED_SEGMENT_CREATION specifies the semantics of deferred segment creation. If set to true, then segments for tables and their dependent objects (LOBs, indexes) will not be created until the first row is inserted into the table.

Before creating a set of tables, if it is known that a significant number of them will not be populated, then consider setting this parameter to true. This saves disk space and minimizes install time.

DG_BROKER_CONFIG_FILEn

Property

Description

Parameter type

String

Syntax

DG_BROKER_CONFIG_FILE[1 | 2] = filename

Default value

Operating system-dependent

Modifiable

ALTER SYSTEM

Range of values

One filename

Basic

No

DG_BROKER_CONFIG_FILEn (where n = 1, 2) specifies the names for the Data Guard broker configuration files.

Every database that is part of a Data Guard broker configuration has two broker configuration files, which contain entries that describe the state and properties of the configuration (such as the sites and databases that are part of the configuration, the roles and properties of each of the databases, and the state of each of the elements of the configuration). Two files are provided so as to always maintain the last known good state of the configuration.

If DG_BROKER_CONFIG_FILEn is not explicitly defined, then it is set to an operating system-specific default value at instance startup. The parameter can only be altered when the DMON (Data Guard broker) process is not running.

See Also:

Oracle Data Guard Broker for more information about setting this parameter

DG_BROKER_START

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SYSTEM

Range of values

true | false

Basic

No

DG_BROKER_START enables Oracle to determine whether or not the Data Guard broker (DMON) process should be started. DMON is a non-fatal Oracle background process and exists as long as the instance exists, whenever this parameter is set to true.

If the site is never going to be configured in a Data Guard broker configuration, then you can leave the parameter unspecified and accept the default value of false. If the site is part of a Data Guard broker configuration, then automatic startup of the DMON process is simplified by setting DG_BROKER_START to true in the initialization parameter file.

DIAGNOSTIC_DEST

Property

Description

Parameter type

String

Syntax

DIAGNOSTIC_DEST = { pathname | directory }

Default value

Derived from the value of the $ORACLE_BASE environment variable. If $ORACLE_BASE is not set, then derived from ORACLE_BASE as set by the Oracle Universal Installer. If ORACLE_BASE is not set, then $ORACLE_HOME/rdbms/log is used.

Modifiable

ALTER SYSTEM

Basic

No

Oracle RAC

This parameter can be set on each instance. Oracle recommends that each instance in a cluster specify a DIAGNOSTIC_DEST directory location that is located on shared disk and that the same value for DIAGNOSTIC_DEST be specified for each instance.

As of Oracle Database 11g Release 1, the diagnostics for each database instance are located in a dedicated directory, which can be specified through the DIAGNOSTIC_DEST initialization parameter. The structure of the directory specified by DIAGNOSTIC_DEST is as follows:

<diagnostic_dest>/diag/rdbms/<dbname>/<instname>

This location is known as the Automatic Diagnostic Repository (ADR) Home. For example, if the database name is proddb and the instance name is proddb1, the ADR home directory would be <diagnostic_dest>/diag/rdbms/proddb/proddb1.

The following files are located under the ADR home directory:

- Trace files - located in subdirectory <adr-home>/trace

- Alert logs - located in subdirectory <adr-home>/alert. In addition, the alert.log file is now in XML format, which conforms to the Oracle ARB logging standard.

- Core files - located in the subdirectory <adr-home>/cdumd

- Incident files - the occurrence of each serious error (for example, ORA-600, ORA-1578, ORA-7445) causes an incident to be created. Each incident is assigned an ID and dumping for each incident (error stack, call stack, block dumps, and so on) is stored in its own file, separated from process trace files. Incident dump files are located in <adr-home>/incident/<incdir#>. You can find the incident dump file location inside the process trace file.

DISK_ASYNCH_IO

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

No

Range of values

true | false

Basic

No

DISK_ASYNCH_IO controls whether I/O to datafiles, control files, and logfiles is asynchronous (that is, whether parallel server processes can overlap I/O requests with CPU processing during table scans). If your platform supports asynchronous I/O to disk, Oracle recommends that you leave this parameter set to its default value. However, if the asynchronous I/O implementation is not stable, you can set this parameter to false to disable asynchronous I/O. If your platform does not support asynchronous I/O to disk, this parameter has no effect.

If you set DISK_ASYNCH_IO to false, then you should also set DBWR_IO_SLAVES to a value other than its default of zero in order to simulate asynchronous I/O.

See Also:

- "DBWR_IO_SLAVES"

- Oracle Database Performance Tuning Guide for more information on asynchronous I/O and on setting this parameter

DISPATCHERS

Property

Description

Parameter type

String

Syntax

DISPATCHERS = 'dispatch_clause'

dispatch_clause::=
(PROTOCOL = protocol) |

(ADDRESS = address) |

(DESCRIPTION = description )

[options_clause]

options_clause::=
(DISPATCHERS = integer |

SESSIONS = integer |

CONNECTIONS = integer |

TICKS = seconds |

POOL = {1 | ON | YES | TRUE | BOTH |

({IN | OUT} = ticks) | 0 | OFF | NO | FALSE |

ticks} |

MULTIPLEX = {1 | ON | YES | TRUE |

0 | OFF | NO | FALSE | BOTH | IN | OUT} |

LISTENER = tnsname |

SERVICE = service |

INDEX = integer)

Default value

If SHARED_SERVERS is greater than 0, then DISPATCHERS defaults to '(PROTOCOL=tcp)', causing 1 TCP/IP dispatcher to be created.

Modifiable

ALTER SYSTEM

Basic

No

DISPATCHERS configures dispatcher processes in the shared server architecture. The parsing software supports a name-value syntax to enable the specification of attributes in a position-independent, case-insensitive manner. For example:

DISPATCHERS = '(PROTOCOL=TCP)(DISPATCHERS=3)'

Attributes may be specified using the full attribute name or any substring beginning with the first 3 characters. For example, SESSIONS can be specified as SES, SESS, SESSI, and so on.

Specify only one of the following attributes: PROTOCOL, ADDRESS, or DESCRIPTION. If you specify either ADDRESS or DESCRIPTION, then you can specify additional network attributes. Doing so supports multi-homed hosts.

dispatch_clause

- PROTOCOL
The network protocol for which the dispatcher generates a listening endpoint.

- ADDRESS
The network protocol address of the endpoint on which the dispatchers listen.

- DESCRIPTION
The network description of the endpoint on which the dispatchers listen, including the protocol address.

options_clause

- DISPATCHERS
The initial number of dispatchers to start. The default is 1.

- SESSIONS
The maximum number of network sessions to allow for each dispatcher. The default is operating system-specific. Most operating systems have a default of 16 KB.

- CONNECTIONS
The maximum number of network connections to allow for each dispatcher. The default is operating system-specific.

- TICKS
The length of a network tick in seconds. The default is 1 second.

- POOL
Enables Connection Pooling.

- An integer indicates that Connection Pooling is enabled for both incoming and outgoing network connections. The number specified is the timeout in ticks for both incoming and outgoing network connections.

- ON, YES, TRUE, and BOTH indicate that Connection Pooling is enabled for both incoming and outgoing network connections. A default timeout of 10 ticks is used for both incoming and outgoing network connections.

- IN indicates that Connection Pooling is enabled for incoming network connections and the default timeout of 10 ticks is used for incoming network connections.

- OUT indicates that Connection Pooling is enabled for outgoing network connections and the default timeout of 10 ticks is used for outgoing network connections.

- NO, OFF, and FALSE indicate that Connection Pooling is disabled for both incoming and outgoing network connections. This is the default.

POOL can also be assigned a name-value string such as: "(IN=10)", "(OUT=20)", or "(IN=10)(OUT=20)". In such cases:

- If an IN numeric value is specified, then Connection Pooling is enabled for incoming connections, and the number specified is the timeout in ticks for incoming network connections.

- If an OUT numeric value is specified, then Connection Pooling is enabled for outgoing network connections, and the number specified is the timeout in ticks for outgoing network connections.

- If the numeric value of a specified timeout is 1, then the default value of 10 ticks is used. If the numeric value is 0, then pooling is not on.

- MULTIPLEX
Enables the Oracle Connection Manager session multiplexing feature.

- The values 1, ON, YES, TRUE, and BOTH indicate that Network Session Multiplex is enabled for both incoming and outgoing network connections.

- The value IN indicates that Network Session Multiplex is enabled for incoming network connections.

- The value OUT indicates that Network Session Multiplexing is enabled for outgoing network connections.

- The values 0, NO, OFF, and FALSE indicate that Network Session Multiplexing is disabled for both incoming and outgoing network connections. This is the default.

- LISTENER
Specifies the network name of an address or address list of the Oracle Net listeners with which the dispatchers will register.

The LISTENER attribute facilitates administration of multi-homed hosts. This attribute specifies the appropriate listeners with which the dispatchers will register. The LISTENER attribute takes precedence over the LOCAL_LISTENER and REMOTE_LISTENER parameters. See "LOCAL_LISTENER" and "REMOTE_LISTENER".

- SERVICE
Specifies one or more names by which clients can connect to the dispatchers. The SERVICE attribute takes precedence over the SERVICE_NAMES parameter.

- INDEX
Use this attribute in an ALTER SYSTEM SET DISPATCHERS statement to indicate which dispatcher configuration you want to modify. (If you specify INDEX in the initialization parameter file, the Oracle Database ignores it.) In an ALTER SYSTEM statement, INDEX specifies the order in which the parameter's values were initialized. The value ranges from 0 (for the first dispatcher configuration) to one less than the total number of dispatcher configurations you define.

For example, if you specify 3 dispatcher configurations in the initialization parameter file, you would modify the third dispatcher configuration by specifying INDEX=2 in the ALTER SYSTEM statement. You could also add an additional dispatcher configuration in the ALTER SYSTEM statement by specifying INDEX=3.

If INDEX is not specified in the ALTER SYSTEM statement, then the PROTOCOL, ADDRESS, or DESCRIPTION attributes must be specified, and if a dispatcher configuration matching this PROTOCOL, ADDRESS, or DESCRIPTION exists, then that configuration will be modified. Otherwise, a new configuration will be added.

DISTRIBUTED_LOCK_TIMEOUT

Property

Description

Parameter type

Integer

Default value

60

Modifiable

No

Range of values

1 to unlimited

Basic

No

DISTRIBUTED_LOCK_TIMEOUT specifies the amount of time (in seconds) for distributed transactions to wait for locked resources.

See Also:

Oracle Database Concepts and Oracle Database Administrator's Guide for more information on data concurrency

DML_LOCKS

Property

Description

Parameter type

Integer

Default value

Derived: 4 * TRANSACTIONS

Modifiable

No

Range of values

20 to unlimited; a setting of 0 disables enqueues

Basic

No

Oracle RAC

You must set this parameter for every instance, and all instances must have positive values or all must be 0.

A DML lock is a lock obtained on a table that is undergoing a DML operation (insert, update, delete). DML_LOCKS specifies the maximum number of DML locks—one for each table modified in a transaction. The value should equal the grand total of locks on tables currently referenced by all users. For example, if three users are modifying data in one table, then three entries would be required. If three users are modifying data in two tables, then six entries would be required.

The default value assumes an average of four tables referenced for each transaction. For some systems, this value may not be enough.

Enqueues are shared memory structures that serialize access to database resources. If you set the value of DML_LOCKS to 0, enqueues are disabled and performance is slightly increased. However, you should be aware of the following restrictions when you set you DML_LOCKS to 0:

- You cannot use DROP TABLE, CREATE INDEX statements

- You cannot use explicit lock statements such as LOCK TABLE IN EXCLUSIVE MODE

- Enterprise Manager cannot run on any instances for which DML_LOCKS is set to 0

Oracle holds more locks during parallel DML than during serial execution. Therefore, if your database supports a lot of parallel DML, you may need to increase the value of this parameter.

See Also:

- Oracle Database Concepts for a discussion of lock and enqueue resources needed for parallel DML

- Oracle Real Application Clusters Administration and Deployment Guide, Oracle Database Concepts, and Oracle Database Administrator's Guide for more information on data concurrency

DST_UPGRADE_INSERT_CONV

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

DST_UPGRADE_INSERT_CONV specifies whether or not internal operators will be allocated on top of TIMESTAMP WITH TIME ZONE (TSTZ) columns of tables which have not been upgraded during the upgrade window of daylight saving time patching for TIMESTAMP WITH TIME ZONE data.

Values:

- true
Internal operators will be allocated on top of TSTZ columns of tables which have not been upgraded. This is the default.

- false
Internal operators will not be allocated on top of TSTZ columns of tables which have not been upgraded.

When DST_UPGRADE_INSERT_CONV is set to true during the upgrade window of the daylight saving time patching process:

- SELECT queries on tables with TSTZ data which have not been upgraded will use internal operators on top of TSTZ columns to present TSTZ data as if they were recorded using the new time zone translation rules.

- DML on tables with TSTZ data which have not been upgraded will use internal operators on top of TSTZ columns to ensure that the TSTZ data is recorded using the old time zone translation rules in order to be consistent with the existing TSTZ data in the same tables.

Note:

Oracle strongly recommends that this parameter is set to true throughout the upgrade window of the daylight saving time patching process. This parameter reduces the performance impact since indexes on TSTZ columns will be disabled whenever internal operators are allocated. If the parameter is set to false, then indexes will be used and this may affect performance of queries against TSTZ data during the DST upgrade window. Turning off this parameter during the upgrade window may corrupt data on disk when DMLs occur for tables with TSTZ data which have not yet been upgraded.

ENABLE_DDL_LOGGING

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

ENABLE_DDL_LOGGING enables or disables the writing of a subset of DDL statements to the alert log.

Note:

The DDL statement written to the alert log may be truncated. You can use DDL triggers to view the entire DDL statement. See Oracle Database PL/SQL Language Reference for more information about DDL triggers.

EVENT

Property

Description

Parameter type

String

Default value

There is no default value.

Modifiable

FAST_START_MTTR_TARGET

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0 to 3600 seconds

Basic

No

Oracle RAC

Multiple instances can have different values, and you can change the values at runtime.

FAST_START_MTTR_TARGET enables you to specify the number of seconds the database takes to perform crash recovery of a single instance. When specified, FAST_START_MTTR_TARGET is overridden by LOG_CHECKPOINT_INTERVAL.

FAST_START_PARALLEL_ROLLBACK

Property

Description

Parameter type

String

Syntax

FAST_START_PARALLEL_ROLLBACK = { HI | LO | FALSE }

Default value

LOW

Modifiable

ALTER SYSTEM

Basic

No

FAST_START_PARALLEL_ROLLBACK specifies the degree of parallelism used when recovering terminated transactions. Terminated transactions are transactions that are active before a system failure. If a system fails when there are uncommitted parallel DML or DDL transactions, then you can speed up transaction recovery during startup by using this parameter.

Values:

- FALSE
Parallel rollback is disabled

- LOW
Limits the maximum degree of parallelism to 2 * CPU_COUNT

- HIGH
Limits the maximum degree of parallelism to 4 * CPU_COUNT

If you change the value of this parameter, then transaction recovery will be stopped and restarted with the new implied degree of parallelism.

FILE_MAPPING

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SYSTEM

Range of values

true | false

Basic

No

FILE_MAPPING specifies whether or not file mapping is enabled. The FMON background process is started to manage the mapping information when file mapping is enabled.

See Also:

Oracle Database Administrator's Guide for more information about the file mapping feature

FILEIO_NETWORK_ADAPTERS

Property

Description

Parameter type

String

Syntax

FILEIO_NETWORK_ADAPTERS = adapter_name [, adapter_name ] ...

Default value

There is no default value.

Modifiable

No

Range of values

One or more network adapter names, separated by commas

Basic

No

FILEIO_NETWORK_ADAPTERS specifies a list of network adapters that can be used to access the disk storage. On platforms where the database files reside in network attached storage, this parameter provides the storage access library the list of network adapters that can be used to access the storage.

The network adapter name is a fully qualified address name of the network card that can be accessed through the host name database or using the Network Information Service. The components of the adapter name are separated by periods. For example, the following is a fully qualified adapter name:

ib1.oracle.com

FILESYSTEMIO_OPTIONS

Property

Description

Parameter type

String

Syntax

FILESYSTEMIO_OPTIONS = { none | setall | directIO | asynch }

Default value

There is no default value.

Modifiable

FILESYSTEMIO_OPTIONS specifies I/O operations for file system files.

FIXED_DATE

Property

Description

Parameter type

String

Syntax

FIXED_DATE = [YYYY-MM-DD-HH24:MI:SS (or the default Oracle date format) | NONE]

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Basic

No

FIXED_DATE enables you to set a constant date that SYSDATE will always return instead of the current date. To undo a fixed date setting, specify FIXED_DATE=NONE. This parameter is useful primarily for testing. The value can be in the format shown above or in the default Oracle date format, without a time.

GCS_SERVER_PROCESSES

Property

Description

Parameter type

Integer

Default value

If 1 - 3 CPUS, then 1
If 4 - 15 CPUs, then 2

If 16 or more CPUs, then 2 + (CPUs / 32). If the result includes a fraction, then the fraction is disregarded. For example, if you had 20 CPUs, then 2 + (20 / 32) would equal 2 GCS processes.

If CLUSTER_DATABASE is set to false, then 0

If ASM, then 1

Modifiable

No

Range of values

1 to 36

Basic

No

Oracle RAC

Multiple instances can have different values.

GCS_SERVER_PROCESSES specifies the number of background GCS server processes (LMS0, ... LMS9 and LMSa, ... LMSz) to serve the inter-instance traffic among Oracle RAC instances. GCS server processes are only seen in an Oracle RAC environment.

GLOBAL_CONTEXT_POOL_SIZE

Property

Description

Parameter type

String

Default value

NULL

Modifiable

No

Range of values

Any integer value in MB

Basic

No

Note:

The GLOBAL_CONTEXT_POOL_SIZE parameter is deprecated. It is retained for backward compatibility only.

GLOBAL_CONTEXT_POOL_SIZE specifies the amount of memory to allocate in the SGA for storing and managing global application context.

GLOBAL_NAMES

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

GLOBAL_NAMES specifies whether a database link is required to have the same name as the database to which it connects.

If the value of GLOBAL_NAMES is false, then no check is performed. If you use or plan to use distributed processing, then Oracle recommends that you set this parameter to true to ensure the use of consistent naming conventions for databases and links in a networked environment.

See Also:

Oracle Database Administrator's Guide for more information on setting this parameter

GLOBAL_TXN_PROCESSES

Property

Description

Parameter type

Integer

Default value

1

Modifiable

ALTER SYSTEM

Range of values

0 to 20

Basic

No

Oracle RAC

Multiple instances can have different values.

GLOBAL_TXN_PROCESSES specifies the initial number of GTXn background processes (GTX0, ... GTX9 and GTXa, ... GTXj) per instance to support global (XA) transactions in an Oracle RAC environment.

If you want to disable the GTXn background processes, then you must set GLOBAL_TXN_PROCESSES to 0 in your parameter file. Setting this parameter to 0 will disable the XA support on an Oracle RAC database. Error ORA-55712 will be returned if you try to run XA transactions on an Oracle RAC database with this parameter set to zer0. You can change the setting to a nonzero value at runtime to turn on the support for XA.

GLOBAL_TXN_PROCESSES is useful for systems that process global (XA) transactions heavily. You do not need to specify a value for this parameter since Oracle Database automatically determines the number of processes and autotunes them, as necessary. GTXn background processes are only seen in an Oracle RAC environment.

See Also:

Oracle Database Advanced Application Developer's Guide for more information about this parameter and Oracle XA

HASH_AREA_SIZE

Property

Description

Parameter type

Integer

Default value

Derived: 2 * SORT_AREA_SIZE

Modifiable

ALTER SESSION

Range of values

0 to operating system-dependent

Basic

No

Note:

Oracle does not recommend using the HASH_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. HASH_AREA_SIZE is retained for backward compatibility.

HASH_AREA_SIZE is relevant to parallel execution operations and to the query portion of DML or DDL statements. It specifies the maximum amount of memory, in bytes, to be used for hash joins.

See Also:

- Oracle Database Concepts for information on hash joins in general

- Oracle Database Performance Tuning Guide for information on calculating an appropriate value for this parameter

HI_SHARED_MEMORY_ADDRESS

Property

Description

Parameter type

Integer

Default value

0

Modifiable

No

Basic

No

HI_SHARED_MEMORY_ADDRESS specifies the starting address at runtime of the system global area (SGA). It is ignored on platforms that specify the SGA's starting address at linktime.

On 64-bit platforms, use HI_SHARED_MEMORY_ADDRESS to specify the high-order 32 bits of a 64-bit address. Use SHARED_MEMORY_ADDRESS to specify the low-order 32 bits of the address (see "SHARED_MEMORY_ADDRESS"). If both parameters are 0 or unspecified, the SGA address defaults to a platform-specific location.

HS_AUTOREGISTER

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SYSTEM

Range of values

true | false

Basic

No

HS_AUTOREGISTER enables or disables automatic self-registration of Heterogeneous Services (HS) agents. When enabled, information is uploaded into the server's data dictionary to describe a previously unknown agent class or a new agent version.

Oracle recommends that you set this parameter to true. Oracle incurs less overhead when establishing subsequent connections through the same agent if self-registered information is available in the server's data dictionary.

See Also:

Oracle Database Heterogeneous Connectivity User's Guide for more information on HS agents

IFILE

Property

Description

Parameter type

Parameter file

Syntax

IFILE = parameter_file_name

Default value

There is no default value.

Modifiable

No

Range of values

Valid parameter filenames

Basic

No

Oracle RAC

Multiple instances can have different values.

Use IFILE to embed another parameter file within the current parameter file. For example:

IFILE = COMMON.ORA

You can have up to three levels of nesting. In this example, the file COMMON.ORA could contain a second IFILE parameter for the file COMMON2.ORA, which could contain a third IFILE parameter for the file GCPARMS.ORA. You can also include multiple parameter files in one parameter file by listing IFILE several times with different values:

IFILE = DBPARMS.ORA
IFILE = GCPARMS.ORA
IFILE = LOGPARMS.ORA

Note:

You must list multiple entries on contiguous lines of the parameter file.

INSTANCE_GROUPS

Property

Description

Parameter type

String

Syntax

INSTANCE_GROUPS = group_name [, group_name ] ...

Default value

There is no default value.

Modifiable

No

Range of values

One or more instance group names, separated by commas

Basic

No

Oracle RAC

Multiple instances can have different values.

Note:

The INSTANCE_GROUPS parameter is deprecated. It is retained for backward compatibility only.

INSTANCE_GROUPS is an Oracle RAC parameter that you can specify only in parallel mode. Used in conjunction with the PARALLEL_INSTANCE_GROUP parameter, it lets you restrict parallel query operations to a limited number of instances.

This parameter specifies one or more instance groups and assigns the current instance to those groups. If one of the specified groups is also specified in the PARALLEL_INSTANCE_GROUP parameter, then Oracle allocates query processes for a parallel operation from this instance.

See Also:

- Oracle Real Application Clusters Administration and Deployment Guide for more information on parallel query execution in a Real Application Clusters environment

- "PARALLEL_INSTANCE_GROUP"

INSTANCE_NAME

Property

Description

Parameter type

String

Syntax

INSTANCE_NAME = instance_id

Default value

The instance's SID
Note: The SID identifies the instance's shared memory on a host, but may not uniquely distinguish this instance from other instances.

Modifiable

No

Range of values

Any alphanumeric characters and the underscore (_) character

Basic

No

In a Real Application Clusters environment, multiple instances can be associated with a single database service. Clients can override Oracle's connection load balancing by specifying a particular instance by which to connect to the database. INSTANCE_NAME specifies the unique name of this instance.

In a single-instance database system, the instance name is usually the same as the database name.

See Also:

Oracle Real Application Clusters Administration and Deployment Guide and Oracle Database Net Services Administrator's Guide for more information

INSTANCE_NUMBER

Property

Description

Parameter type

Integer

Default value

0 (zero)

Modifiable

No

Range of values

1 to maximum number of instances specified when the database was created

Basic

Yes

Oracle RAC

You must set this parameter for every instance, and all instances must have different values.

INSTANCE_NUMBER is an Oracle RAC parameter that can be specified in parallel mode or exclusive mode. It specifies a unique number that maps the instance to one free list group for each database object created with storage parameter FREELIST GROUPS.

The INSTANCE parameter of the ALTER TABLE ... ALLOCATE EXTENT statement assigns an extent to a particular free list group. If you set INSTANCE_NUMBER to the value specified for the INSTANCE parameter, the instance uses that extent for inserts and for updates that expand rows.

The practical maximum value of this parameter is the maximum number of instances specified in the CREATE DATABASE statement. The absolute maximum is operating system-dependent.

See Also:

Oracle Real Application Clusters Administration and Deployment Guide for more information

INSTANCE_TYPE

Property

Description

Parameter type

String

Syntax

INSTANCE_TYPE = { RDBMS | ASM }

Default value

RDBMS

Modifiable

JAVA_MAX_SESSIONSPACE_SIZE

Property

Description

Parameter type

Integer

Default value

0

Modifiable

No

Range of values

0 to 2 GB - 1

Basic

No

Java session space is the memory that holds Java state from one database call to another. JAVA_MAX_SESSIONSPACE_SIZE specifies (in bytes) the maximum amount of session space made available to a Java program executing in the server. When a user's session-duration Java state attempts to exceed this amount, the Java virtual machine kills the session with an out-of-memory failure.

See Also:

- Oracle Database Java Developer's Guide

- "JAVA_SOFT_SESSIONSPACE_LIMIT"

JAVA_POOL_SIZE

Property

Description

Parameter type

Big integer

Syntax

JAVA_POOL_SIZE = integer [K | M | G]

Default value

If SGA_TARGET is set: If the parameter is not specified, then the default is 0 (internally determined by the Oracle Database). If the parameter is specified, then the user-specified value indicates a minimum value for the memory pool.
If SGA_TARGET is not set: 24 MB, rounded up to the nearest granule size

Modifiable

ALTER SYSTEM

Range of values

Minimum: 0 (values greater than zero are rounded up to the nearest granule size)
Maximum: operating system-dependent

Basic

No

JAVA_POOL_SIZE specifies (in bytes) the size of the Java pool, from which the Java memory manager allocates most Java state during runtime execution. This memory includes the shared in-memory representation of Java method and class definitions, as well as the Java objects that are migrated to the Java session space at end-of-call.

See Also:

Oracle Database Java Developer's Guide for information on adjusting this parameter

JAVA_SOFT_SESSIONSPACE_LIMIT

Property

Description

Parameter type

Integer

Default value

0

Modifiable

No

Range of values

0 to 2 GB - 1

Basic

No

Java session space is the memory that holds Java state from one database call to another. JAVA_SOFT_SESSIONSPACE_LIMIT specifies (in bytes) a soft limit on Java memory usage in a session, as a means to warn you if a user's session-duration Java state is using too much memory. When a user's session-duration Java state exceeds this size, Oracle generates a warning that goes into the trace files.

See Also:

- Oracle Database Java Developer's Guide for more information on this parameter

- "JAVA_MAX_SESSIONSPACE_SIZE"

JOB_QUEUE_PROCESSES

Property

Description

Parameter type

Integer

Default value

1000

Modifiable

ALTER SYSTEM

Range of values

0 to 1000

Basic

No

Oracle RAC

Multiple instances can have different values.

JOB_QUEUE_PROCESSES specifies the maximum number of job slaves per instance that can be created for the execution of DBMS_JOB jobs and Oracle Scheduler (DBMS_SCHEDULER) jobs. DBMS_JOB and Oracle Scheduler share the same job coordinator and job slaves, and they are both controlled by the JOB_QUEUE_PROCESSES parameter.

If the value of JOB_QUEUE_PROCESSES is set to 0, then DBMS_JOB jobs and Oracle Scheduler jobs will not run on the instance.

If JOB_QUEUE_PROCESSES is set to a value in the range of 1 to 1000, then DBMS_JOB jobs and Oracle Scheduler jobs will run. The actual number of job slaves created for Oracle Scheduler jobs is auto-tuned by the Scheduler depending on several factors, including available resources, Resource Manager settings, and currently running jobs. However, the combined total number of job slaves running DBMS_JOB jobs and Oracle Scheduler jobs on an instance can never exceed the value of JOB_QUEUE_PROCESSES for that instance.

Advanced replication uses Oracle Scheduler for data refreshes. Oracle Streams Advanced Queuing uses Oracle Scheduler for message propagation. Materialized views use Oracle Scheduler for automatic refreshes. Setting JOB_QUEUE_PROCESS to 0 will disable these features as well as any other features that use Oracle Scheduler or DBMS_JOB.

See Also:

- Oracle Database PL/SQL Packages and Types Reference for more information on the DBMS_SCHEDULER package

LARGE_POOL_SIZE

Property

Description

Parameter type

Big integer

Syntax

LARGE_POOL_SIZE = integer [K | M | G]

Default value

If SGA_TARGET is set, but a value is not specified for LARGE_POOL_SIZE, then the default is 0 (internally determined by the Oracle database). If LARGE_POOL_SIZE is specified, then the user-specified value indicates a minimum value for the memory pool.
If SGA_TARGET is not set, 0 if both of the following are true:

- The pool is not required by parallel execution

- DBWR_IO_SLAVES is not set

Otherwise, derived from the values of PARALLEL_MAX_SERVERS, PARALLEL_THREADS_PER_CPU, CLUSTER_DATABASE_INSTANCES, DISPATCHERS, and DBWR_IO_SLAVES.

Note that a value derived in this way does not take into account the requirements used for Automatic Storage Management files. As a general guideline, you should add 600K to the size of the SGA on a database instance using ASM.

Modifiable

ALTER SYSTEM

Range of values

Minimum: the granule size
Maximum: operating system-dependent

Basic

No

LARGE_POOL_SIZE specifies (in bytes) the size of the large pool allocation heap. The large pool allocation heap is used in shared server systems for session memory, by parallel execution for message buffers, and by backup processes for disk I/O buffers. Parallel execution allocates buffers out of the large pool only when SGA_TARGET is set.

Caution:

When Oracle derives a default value, it adds 250K for each session for the shared server if DISPATCHERS is configured. The final derived value also includes a port-specific amount of memory for backup I/O buffers. The total derived default value can either be too large to allocate or can cause performance problems. In that case, set LARGE_POOL_SIZE to a number sufficiently small so that the database can start.

You can specify the value of this parameter using a number, optionally followed by K or M to specify kilobytes or megabytes, respectively. If you do not specify K or M, then the number is taken as bytes.

LDAP_DIRECTORY_ACCESS

Property

Description

Parameter type

String

Syntax

LDAP_DIRECTORY_ACCESS = { NONE | PASSWORD | SSL }

Default value

NONE

Modifiable

ALTER SYSTEM

Basic

No

LDAP_DIRECTORY_ACCESS specifies whether Oracle refers to Oracle Internet Directory for user authentication information. If directory access is turned on, then this parameter also specifies how users are authenticated.

Values:

- NONE
Oracle does not refer to Oracle Internet Directory for Enterprise User Security information.

- PASSWORD
Oracle tries to connect to the enterprise directory service using the database password stored in the database wallet. If that fails, then the Oracle Internet Directory connection fails and the database will not be able to retrieve enterprise roles and schema mappings upon enterprise user login.

- SSL
Oracle tries to connect to Oracle Internet Directory using SSL.

LDAP_DIRECTORY_SYSAUTH

Property

Description

Parameter type

String

Syntax

LDAP_DIRECTORY_SYSAUTH = { yes | no }

Default value

no

Modifiable

No

Basic

Yes

LDAP_DIRECTORY_SYSAUTH enables or disables directory-based authorization for SYSDBA and SYSOPER.

LICENSE_MAX_SESSIONS

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0 to number of session licenses

Basic

No

Oracle RAC

Multiple instances can have different values, but the total for all instances mounting a database should be less than or equal to the total number of sessions licensed for that database.

LICENSE_MAX_SESSIONS specifies the maximum number of concurrent user sessions allowed. When this limit is reached, only users with the RESTRICTED SESSION privilege can connect to the database. Users who are not able to connect receive a warning message indicating that the system has reached maximum capacity.

A zero value indicates that concurrent usage (session) licensing is not enforced. If you set this parameter to a nonzero number, you might also want to set LICENSE_SESSIONS_WARNING (see "LICENSE_SESSIONS_WARNING").

Do not enable both concurrent usage licensing and user licensing. Set either LICENSE_MAX_SESSIONS or LICENSE_MAX_USERS to zero.

See Also:

Oracle Database Administrator's Guide for more information on setting this parameter

LICENSE_MAX_USERS

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0 to number of user licenses

Basic

No

Oracle RAC

Oracle recommends that multiple instances have the same value.

LICENSE_MAX_USERS specifies the maximum number of users you can create in the database. When you reach this limit, you cannot create more users. You can, however, increase the limit.

Do not enable both concurrent usage (session) licensing and user licensing. Set either LICENSE_MAX_SESSIONS or LICENSE_MAX_USERS to zero.

See Also:

Oracle Database Administrator's Guide for more information on setting this parameter

LICENSE_SESSIONS_WARNING

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0 to value of LICENSE_MAX_SESSIONS parameter

Basic

No

Oracle RAC

Multiple instances can have different values.

LICENSE_SESSIONS_WARNING specifies a warning limit on the number of concurrent user sessions. When this limit is reached, additional users can connect, but Oracle writes a message in the alert file for each new connection. Users with RESTRICTED SESSION privilege who connect after the limit is reached receive a warning message stating that the system is nearing its maximum capacity.

If this parameter is set to zero, no warning is given as you approach the concurrent usage (session) limit. If you set this parameter to a nonzero number, you should also set LICENSE_MAX_SESSIONS (see "LICENSE_MAX_SESSIONS").

LISTENER_NETWORKS

Property

Description

Parameter type

String

Syntax

LISTENER_NETWORKS =

'((NAME=network_name)
(LOCAL_LISTENER=["]listener_address[,...]["])
[(REMOTE_LISTENER=["]listener_address[,...]["])])'
[,...]

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Basic

No

LISTENER_NETWORKS specifies one or more sets of local & remote listeners for cross-registration. All listeners within the same network_name will cross-register.

If a network_name is specified multiple times, then the resulting listener set is the union of each specification. This can be used to specify sets that require more than 255 characters, which is the per element limit.

The listener_address specifies a string that is an address, address list, or an alias that resolves to an address or address list of Oracle Net listeners. If an alias, the address or address list is specified in the TNSNAMES.ORA file or another address repository as configured for your system.

If a comma is used to specify a listener_address list, then the set of addresses must be surrounded by double quotes.

See Also:

Oracle Database Net Services Administrator's Guide for more information on setting this parameter

LOCAL_LISTENER

Property

Description

Parameter type

String

Syntax

LOCAL_LISTENER = network_name

Default value

(ADDRESS = (PROTOCOL=TCP)(HOST=hostname)(PORT=1521)) where hostname is the network name of the local host.

Modifiable

ALTER SYSTEM

Basic

No

LOCAL_LISTENER specifies a network name that resolves to an address or address list of Oracle Net local listeners (that is, listeners that are running on the same machine as this instance). The address or address list is specified in the TNSNAMES.ORA file or other address repository as configured for your system.

See Also:

LOCK_NAME_SPACE

Property

Description

Parameter type

String

Syntax

LOCK_NAME_SPACE = namespace

Default value

There is no default value.

Modifiable

No

Range of values

Up to 8 alphanumeric characters. No special characters allowed.

Basic

No

Note:

The LOCK_NAME_SPACE parameter is deprecated. It is retained for backward compatibility only.

LOCK_NAME_SPACE specifies the namespace that the distributed lock manager (DLM) uses to generate lock names. Consider setting this parameter if a standby or clone database has the same database name on the same cluster as the primary database.

If the standby database resides on the same file system as the primary database, then set LOCK_NAME_SPACE in the standby parameter file to a distinct value such as the following:

LOCK_NAME_SPACE = standby

LOCK_SGA

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

Basic

No

LOCK_SGA locks the entire SGA into physical memory. It is usually advisable to lock the SGA into real (physical) memory, especially if the use of virtual memory would include storing some of the SGA using disk space. This parameter is ignored on platforms that do not support it.

LOG_ARCHIVE_CONFIG

Property

Description

Parameter type

String

Syntax

LOG_ARCHIVE_CONFIG =

{
[ SEND | NOSEND ]
[ RECEIVE | NORECEIVE ]
[ DG_CONFIG=(remote_db_unique_name1 [, ... remote_db_unique_name9) | NODG_CONFIG ]
}

Default value

'SEND, RECEIVE, NODG_CONFIG'

Modifiable

ALTER SYSTEM

Basic

No

LOG_ARCHIVE_CONFIG enables or disables the sending of redo logs to remote destinations and the receipt of remote redo logs, and specifies the unique database names (DB_UNIQUE_NAME) for each database in the Data Guard configuration.

Values:

- SEND
Enables the sending of redo logs to remote destinations

- NOSEND
Disables the sending of redo logs to remote destinations

- RECEIVE
Enables the receipt of remotely archived redo logs

- NORECEIVE
Disables the receipt of remotely archived redo logs

- DG_CONFIG
Specifies a list of up to 9 unique database names (defined with the DB_UNIQUE_NAME initialization parameter) for all of the databases in the Data Guard configuration.

- NODG_CONFIG
Eliminates the list of service provider names previously specified with the DG_CONFIG option.

LOG_ARCHIVE_DEST

Property

Description

Parameter type

String

Syntax

LOG_ARCHIVE_DEST = filespec

Default value

Null

Modifiable

ALTER SYSTEM

Range of values

Any valid path or device name, except raw partitions

Basic

No

Oracle RAC

Multiple instances can have different values.

Note:

For Enterprise Edition users, this parameter has been deprecated in favor of the LOG_ARCHIVE_DEST_n parameters. If Oracle Enterprise Edition is not installed or it is installed, but you have not specified any LOG_ARCHIVE_DEST_n parameters, this parameter is valid.

LOG_ARCHIVE_DEST is applicable only if you are running the database in ARCHIVELOG mode or are recovering a database from archived redo logs. LOG_ARCHIVE_DEST is incompatible with the LOG_ARCHIVE_DEST_n parameters, and must be defined as the null string ("") or (' ') when any LOG_ARCHIVE_DEST_n parameter has a value other than a null string. Use a text string to specify the default location and root of the disk file or tape device when archiving redo log files. (Archiving to tape is not supported on all operating systems.) The value cannot be a raw partition.

If LOG_ARCHIVE_DEST is not explicitly defined and all the LOG_ARCHIVE_DEST_n parameters have null string values, LOG_ARCHIVE_DEST is set to an operating system-specific default value on instance startup.

To override the destination that this parameter specifies, either specify a different destination for manual archiving or use the SQL*Plus statement ARCHIVE LOG START filespec for automatic archiving, where filespec is the new archive destination. To permanently change the destination, use the statement ALTER SYSTEM SET LOG_ARCHIVE_DEST = filespec, where filespec is the new archive destination.

Neither LOG_ARCHIVE_DEST nor LOG_ARCHIVE_FORMAT have to be complete file or directory specifiers themselves; they only need to form a valid file path after the variables are substituted into LOG_ARCHIVE_FORMAT and the two parameters are concatenated together.

Modifiable

Most attributes are modifiable by ALTER SESSION and ALTER SYSTEM, but some are not. See Oracle Data Guard Concepts and Administration for further information.

Basic

Yes

The LOG_ARCHIVE_DEST_n initialization parameter defines up to 31 (where n = 1, 2, 3, ... 31) destinations, each of which must specify either the LOCATION or the SERVICE attribute to specify where to archive the redo data. All other attributes are optional. Note that whether you are specifying the LOCATION attribute or the SERVICE attribute, it must be the first attribute supplied in the list of attributes.

If you choose not to enter any attributes, then you can specify a NULL string by entering the following:

LOG_ARCHIVE_DEST_n=' ';

You set the attributes for the LOG_ARCHIVE_DEST_n initialization parameter to control different aspects of how redo transport services transfer redo data from a production or primary database destination to another (standby) database destination. You can query the V$ARCHIVE_DEST view to see the current attribute settings for each destination (n).

Note:

Some of the attributes for this parameter are deprecated, but are being retained for backward compatibility. See "Deprecated Attributes for LOG_ARCHIVE_DEST_n".

For every LOG_ARCHIVE_DEST_n initialization parameter that you define, you must specify a corresponding LOG_ARCHIVE_DEST_STATE_n parameter. The LOG_ARCHIVE_DEST_STATE_n (where n is an integer from 1 to 31) initialization parameter specifies whether the corresponding destination is currently enabled or disabled.

See Also:

"LOG_ARCHIVE_DEST_STATE_n"

Destinations LOG_ARCHIVE_DEST_11 through LOG_ARCHIVE_DEST_31 do not support the SYNC, ARCH, LOCATION, MANDATORY, or ALTERNATE attributes, and cannot be specified as the target of the ALTERNATE attribute.

LOG_ARCHIVE_DEST_11 through LOG_ARCHIVE_DEST_31 can only be used when the COMPATIBLE initialization parameter is set to 11.2.0 or higher.

Values:

See Also:

Oracle Data Guard Concepts and Administration for detailed descriptions of all the values listed in this section

- AFFIRM and NOAFFIRM
Control whether a redo transport destination acknowledges received redo data before or after writing it to the standby redo log. The default is NOAFFIRM.

- ALTERNATE=LOG_ARCHIVE_DEST_n
Specifies an alternate archiving destination to be used when the original destination fails. There is no default value; if an alternate destination is not specified, then archiving does not automatically change to another destination if the original destination fails.

- ASYNC
The redo data generated by a transaction need not have been received at a destination which has this attribute before that transaction can commit. This is the default behavior if neither SYNC nor ASYNC is specified.

- COMPRESSION
Indicates whether network compression is enabled or disabled.

The COMPRESSION attribute is ignored if the Advanced Compression option has not been enabled.

- DB_UNIQUE_NAME=name
Specifies a unique name for the database at this destination. You must specify a name; there is no default value.

- DELAY[=minutes]
Specifies a minimum time lag between when redo data is archived on a standby site and when the archived redo log file is applied to the standby database. If you specify the DELAY attribute without a time interval, the default is 30 minutes.

- LOCATION=local_disk_directory or USE_DB_RECOVERY_FILE_DEST
Specifies either a local file system destination or the directory, file system, or Automatic Storage Manager disk group that will serve as the fast recovery area. You must specify this attribute for at least one destination. You can specify either a local disk directory or fast recovery area with the LOCATION attribute. You must include either the LOCATION or the SERVICE attribute for each destination to specify where to archive the redo data.

- MANDATORY
Specifies that the transmission of redo data to the destination must succeed before the local online redo log file can be made available for reuse. If the MANDATORY attribute is not specified, then the destination is optional.

- MAX_CONNECTIONS
Specifies the maximum number of network connections that can be used to transmit redo data to this destination. The default is 1.

- MAX_FAILURE
Controls the consecutive number of times redo transport services attempt to reestablish communication and transmit redo data to a failed destination before the primary database permanently gives up on the standby database.

- NET_TIMEOUT=seconds
Specifies the number of seconds the log writer process on the primary system waits for status from the network server (LNSn) process before terminating the network connection. The default is 30 seconds.

- NOREGISTER
Indicates that the location of the archived redo log file is not to be recorded at the corresponding destination.

- REOPEN[=seconds]
Specifies the minimum number of seconds before the archiver processes (ARCn) or the log writer process (LGWR) should try again to access a previously failed destination. The default is 300 seconds.

- SERVICE=net_service_name
Specifies a valid Oracle Net service name (SERVICE=net_service_name) that identifies the remote Oracle database instance to which redo data will be sent. Each destination must specify either the LOCATION or the SERVICE attribute. There is no default net service name.

- SYNC
The redo data generated by a transaction must have been received by every enabled destination which has this attribute before that transaction can commit.

- TEMPLATE=filename_template_%t_%s_%r
Specifies a pathname and a filename template for archived redo log files created at a redo transport destination that contain redo data from the database where this attribute is specified. This attribute overrides the value of the LOG_ARCHIVE_FORMAT initialization parameter at a redo transport destination. This attribute does not have a default value.

- VALID_FOR=(redo_log_type, database_role)
Identifies when redo transport services can transmit redo data to destinations based on the following factors:

- redo_log_type—whether online redo log files, standby redo log files, or both are currently being archived on the database at this destination

- database_role—whether the database is currently running in the primary or the standby role

Deprecated Attributes for LOG_ARCHIVE_DEST_n

The following attributes are deprecated for the LOG_ARCHIVE_DEST_n parameter. They are retained for backward compatibility only.

Table 1-2 Deprecated Attributes on the LOG_ARCHIVE_DEST_n Initialization Parameter

Deprecated Attribute

Alternative

ARCH

Specify SYNC or ASYNC. ASYNC is the default if neither attribute is specified.

LGWR

Specify SYNC or ASYNC. ASYNC is the default if neither attribute is specified.

OPTIONAL

Destinations are optional by default.

VERIFY

None. This attribute is only used with the deprecated ARCH attribute.

In addition, note the following changes to the ASYNC and SYNC attributes:

- The BLOCKS keyword on the ASYNC attribute is no longer needed.
It is no longer necessary to set this keyword because Data Guard dynamically adjusts the block count up or down to an appropriate number of blocks, as necessary.

- The PARALLEL and NOPARALLEL keywords on the SYNC attribute are no longer needed.

LOG_ARCHIVE_DEST_STATE_n

Property

Description

Parameter type

String

Syntax

LOG_ARCHIVE_DEST_STATE_[1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31] = { enable | defer | alternate }

Default value

enable

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

Yes

The LOG_ARCHIVE_DEST_STATE_n parameters (where n = 1, 2, 3, ... 31) specify the availability state of the corresponding destination. The parameter suffix (1 through 31) specifies one of the corresponding LOG_ARCHIVE_DEST_n destination parameters.

Values:

- enable
Specifies that a valid log archive destination can be used for a subsequent archiving operation (automatic or manual). This is the default.

- defer
Specifies that valid destination information and attributes are preserved, but the destination is excluded from archiving operations until re-enabled.

- alternate
Specifies that a log archive destination is not enabled but will become enabled if communications to another destination fail.

The LOG_ARCHIVE_DEST_STATE_n parameters have no effect on the ENABLE state for the LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST parameters.

The V$ARCHIVE_DEST dynamic performance view shows values in use for the current session. The DEST_ID column of that view corresponds to the archive destination suffix n.

LOG_ARCHIVE_DUPLEX_DEST

Property

Description

Parameter type

String

Syntax

LOG_ARCHIVE_DUPLEX_DEST = filespec

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Range of values

Either a null string or any valid path or device name, except raw partitions

Basic

No

Note:

If you are using Oracle Enterprise Edition, this parameter is deprecated in favor of the LOG_ARCHIVE_DEST_n parameters. If Oracle Enterprise Edition is not installed or it is installed but you have not specified any LOG_ARCHIVE_DEST_n parameters, this parameter is valid.

LOG_ARCHIVE_DUPLEX_DEST is similar to the initialization parameter LOG_ARCHIVE_DEST. This parameter specifies a second archive destination: the duplex archive destination. This duplex archive destination can be either a must-succeed or a best-effort archive destination, depending on how many archive destinations must succeed (as specified in the LOG_ARCHIVE_MIN_SUCCEED_DEST parameter).

The default setting of a null string ("") or (' ') indicates that a duplex archive destination does not exist.

See Also:

- "LOG_ARCHIVE_DEST_n"

- "LOG_ARCHIVE_MIN_SUCCEED_DEST"

- "V$ARCHIVE_DEST"

LOG_ARCHIVE_FORMAT

Property

Description

Parameter type

String

Syntax

LOG_ARCHIVE_FORMAT = filename

Default value

Operating system-dependent

Modifiable

No

Range of values

Any string that resolves to a valid filename

Basic

No

Oracle RAC

Multiple instances can have different values, but identical values are recommended.

LOG_ARCHIVE_FORMAT is applicable only if you are using the redo log in ARCHIVELOG mode. Use a text string and variables to specify the default filename format when archiving redo log files. The string generated from this format is appended to the string specified in the LOG_ARCHIVE_DEST parameter.

The following variables can be used in the format:

%s log sequence number

%S log sequence number, zero filled

%t thread number

%T thread number, zero filled

%a activation ID

%d database ID

%r resetlogs ID that ensures unique names are constructed for the archived log files across multiple incarnations of the database

Using uppercase letters for the variables (for example, %S) causes the value to be fixed length and padded to the left with zeros. An example of specifying the archive redo log filename format follows:

LOG_ARCHIVE_FORMAT = 'log%t_%s_%r.arc'

Archive log file names must contain each of the elements %s (sequence), %t (thread), and %r (resetlogs ID) to ensure that all archive log file names are unique. If the LOG_ARCHIVE_FORMAT initialization parameter is set in the parameter file, then make sure the parameter value contains the %s, %t, and %r elements. Otherwise, the following error is displayed at the time of instance startup:

ORA-19905: log_archive_format must contain %s, %t and %r

Neither LOG_ARCHIVE_DEST nor LOG_ARCHIVE_FORMAT have to be complete file or directory specifiers themselves; they only need to form a valid file path after the variables are substituted into LOG_ARCHIVE_FORMAT and the two parameters are concatenated together.

See Also:

- Oracle Database Backup and Recovery User's Guide, Oracle Data Guard Concepts and Administration, and Oracle Real Application Clusters Administration and Deployment Guide for more information on setting this parameter

LOG_ARCHIVE_LOCAL_FIRST

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SYSTEM

Range of values

true | false

Basic

No

Note:

The LOG_ARCHIVE_LOCAL_FIRST parameter is deprecated. It is retained for backward compatibility only.

LOG_ARCHIVE_LOCAL_FIRST specifies when the archiver processes (ARCn) transmit redo data to remote standby database destinations.

Values:

- true
Directs the ARCn process to transmit redo data after the online redo log file has been completely and successfully archived to at least one local destination. This is the default value.

Because the online redo log files are archived locally first, the LGWR process reuses the online redo log files much earlier than would be possible if the ARCn processes archived to the standby database concurrently with the local destination. This behavior is useful when archiving to remote destinations that use a slow network connection, such as a long-distance wide area network (WAN).

- false
Directs the ARCn process to transmit redo data at the same time the online redo log file is archived to the local destinations. This results in redo data being promptly dispatched to the remote standby database destination.

Setting LOG_ARCHIVE_LOCAL_FIRST to false is most useful for faster network connections, such as high-speed local area networks (LAN).

If LOG_ARCHIVE_LOCAL_FIRST is set to true, then it is not used on a physical standby database and any database for which the following attributes have been specified in the LOG_ARCHIVE_DEST_n initialization parameter:

- MANDATORY

- LOCAL

If LOG_ARCHIVE_LOCAL_FIRST is set to true, then it is ignored during certain operations, such as during a switchover, which requires synchronized archival operations. If the destination was explicitly configured to use the log writer process (by specifying the LGWR attribute in the LOG_ARCHIVE_DEST_n initialization parameter), but for some reason the log writer process becomes unable to archive to the destination, then Data Guard will revert to using the ARCn process to complete archival operations using the default behavior, even if LOG_ARCHIVE_LOCAL_FIRST is set to false.

For example, if a standby database problem or a network problem causes the LGWR process to fail, then the ARCn process will complete the archival. Data Guard minimizes the effect on the primary database as much as possible by archiving to the local destination first to ensure the online redo log files are available to the LGWR process as quickly as possible.

LOG_ARCHIVE_MAX_PROCESSES

Property

Description

LOG_ARCHIVE_MIN_SUCCEED_DEST

Property

Description

Parameter type

Integer

Default value

1

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

1 to 10 if you are using LOG_ARCHIVE_DEST_n
1 or 2 if you are using LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST

Basic

No

LOG_ARCHIVE_MIN_SUCCEED_DEST defines the minimum number of destinations that must succeed in order for the online logfile to be available for reuse.

- If you are using the LOG_ARCHIVE_DEST_n parameters and automatic archiving is enabled, then the value of this parameter cannot exceed the number of enabled, valid destinations specified as MANDATORY plus the number of enabled, valid destinations that are configured with the OPTIONAL and LOCATION attributes.

- If you are using LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST and automatic archiving is enabled, a value of 1 specifies that the destination specified in LOG_ARCHIVE_DEST must succeed. A value of 2 specifies that the destinations specified in both parameters must succeed.

If the value of this parameter is less than the number of enabled, valid MANDATORY destinations, this parameter is ignored in favor of the MANDATORY destination count. If the value is more than the number of enabled, valid MANDATORY destinations, then some of the enabled, valid destinations configured with the OPTIONAL and LOCATION attributes are treated as MANDATORY.

You can switch dynamically from using the older parameters to the LOG_ARCHIVE_DEST_n parameter using ALTER SYSTEM, as follows:

1. Set LOG_ARCHIVE_MIN_SUCCEED_DEST to 1.

2. Set the value of LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST to the null string.

3. Set the desired number of destinations for the LOG_ARCHIVE_DEST_n parameters.

4. Reset LOG_ARCHIVE_MIN_SUCCEED_DEST to the desired value.

LOG_ARCHIVE_TRACE

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0, 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192

Basic

No

Oracle RAC

Multiple instances can have different values.

LOG_ARCHIVE_TRACE controls output generated by the archivelog process.

This process can be initiated by any of the following:

- An ARCn background process (designated as ARCn in the output logs)

- An explicit session-invoked foreground process (designated as ARCH in the output logs)

The valid values have the following meanings:

- 0: Disable archivelog tracing (this is the default)

- 1: Track archival of redo log file

- 2: Track archival status of each archivelog destination

- 4: Track archival operational phase

- 8: Track archivelog destination activity

- 16: Track detailed archivelog destination activity

- 32: Track archivelog destination parameter modifications

- 64: Track ARCn process state activity

- 128: Track FAL (fetch archived log) server related activities

- 256: Track RFS Logical Client

- 512: Track LGWR redo shipping network activity

- 1024: Track RFS Physical Client

- 2048: Track RFS/ARCn Ping Heartbeat

- 4096: Track Real Time Apply

- 8192: Track Redo Apply (Media Recovery or Physical Standby)

You can combine tracing levels by adding together the values of the desired tracing levels. For example, a setting of 3 will generate level 1 and level 2 trace output. You can set different values for the primary and standby database.

When this parameter is set to the default value of 0, Oracle will still generate appropriate alert and trace entries in response to error conditions. If you change the value of this parameter dynamically in an ALTER SYSTEM statement, the changes will take effect at the start of the next archivelog operation.

LOG_BUFFER

Property

Description

Parameter type

Integer

Default value

5 MB to 32 MB, depending on the size of the SGA, CPU count, and whether the operating system is 32-bit or 64-bit

Modifiable

No

Range of values

2 MB to 64 MB (32-bit operating systems)
2 MB to 256 MB (64-bit operating systems)

Basic

No

LOG_BUFFER specifies the amount of memory (in bytes) that Oracle uses when buffering redo entries to a redo log file. Redo log entries contain a record of the changes that have been made to the database block buffers. The LGWR process writes redo log entries from the log buffer to a redo log file.

The log buffer size depends on the number of redo strands in the system. One redo strand is allocated for every 16 CPUs and has a default size of 2 MB. Oracle allocates a minimum of 2 redo strands per instance. When the log buffer size is not specified, any remaining memory in the redo granules is given to the log buffer.

LOG_CHECKPOINT_INTERVAL

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0 to 2^31 - 1

Basic

No

Oracle RAC

Multiple instances can have different values.

LOG_CHECKPOINT_INTERVAL specifies the frequency of checkpoints in terms of the number of redo log file blocks that can exist between an incremental checkpoint and the last block written to the redo log. This number refers to physical operating system blocks, not database blocks.

Regardless of this value, a checkpoint always occurs when switching from one online redo log file to another. Therefore, if the value exceeds the actual redo log file size, checkpoints occur only when switching logs. Checkpoint frequency is one of the factors that influence the time required for the database to recover from an unexpected failure.

Notes:

- Specifying a value of 0 (zero) for LOG_CHECKPOINT_INTERVAL has the same effect as setting the parameter to infinity and causes the parameter to be ignored. Only nonzero values of this parameter are considered meaningful.

- Recovery I/O can also be limited by setting the LOG_CHECKPOINT_TIMEOUT parameter or by the size specified for the smallest redo log. For information on which mechanism is controlling checkpointing behavior, query the V$INSTANCE_RECOVERY view.

LOG_CHECKPOINT_TIMEOUT

Property

Description

Parameter type

Integer

Default value

1800

Modifiable

ALTER SYSTEM

Range of values

0 to 2^31 - 1

Basic

No

Oracle RAC

Multiple instances can have different values.

LOG_CHECKPOINT_TIMEOUT specifies (in seconds) the amount of time that has passed since the incremental checkpoint at the position where the last write to the redo log (sometimes called the tail of the log) occurred. This parameter also signifies that no buffer will remain dirty (in the cache) for more than integer seconds.

Specifying a value of 0 for the timeout disables time-based checkpoints. Hence, setting the value to 0 is not recommended unless FAST_START_MTTR_TARGET is set.

Notes:

- A checkpoint scheduled to occur because of this parameter is delayed until the completion of the previous checkpoint if the previous checkpoint has not yet completed.

- Recovery I/O can also be limited by setting the LOG_CHECKPOINT_INTERVAL parameter or by the size specified for the smallest redo log. For information on which mechanism is controlling checkpointing behavior, query the V$INSTANCE_RECOVERY view.

LOG_CHECKPOINTS_TO_ALERT

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SYSTEM

Range of values

true | false

Basic

No

LOG_CHECKPOINTS_TO_ALERT lets you log your checkpoints to the alert file. Doing so is useful for determining whether checkpoints are occurring at the desired frequency.

LOG_FILE_NAME_CONVERT

Property

Description

Parameter type

String

Syntax

LOG_FILE_NAME_CONVERT = 'string1' , 'string2' , 'string3' , 'string4' , ...
Where:

- string1 is the pattern of the primary database filename

- string2 is the pattern of the standby database filename

- string3 is the pattern of the primary database filename

- string4 is the pattern of the standby database filename

You can use as many pairs of primary and standby replacement strings as required. You can use single or double quotation marks.

The following are example settings that are acceptable:

LOG_FILE_NAME_CONVERT = '/dbs/t1/','/dbs/t1/s','dbs/t2/ ','dbs/t2/s_'

Default value

There is no default value.

Modifiable

ALTER SESSION

Basic

No

LOG_FILE_NAME_CONVERT converts the filename of a new log file on the primary database to the filename of a log file on the standby database. If you add a log file to the primary database, you must add a corresponding file to the standby database.

If you specify an odd number of strings (the last string has no corresponding replacement string), an error is signalled during startup. If the filename being converted matches more than one pattern in the pattern/replace string list, the first matched pattern takes effect. There is no limit on the number of pairs that you can specify in this parameter (other than the hard limit of the maximum length of multivalue parameters).

When the standby database is updated, this parameter converts the log file name on the primary database to the log file name on the standby database. The file must exist on the standby database and must be writable or the recovery process will halt with an error.

The first string is the pattern found in the log file names on the primary database. The second string is the pattern found in the log file names on the standby database.

You should also use LOG_FILE_NAME_CONVERT to rename the logfiles in the clone control file when setting up the clone database during tablespace point-in-time recovery.

MAX_DISPATCHERS

Property

Description

Parameter type

Integer

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Range of values

If MAX_DISPATCHERS is specified, then it should be greater than or equal to the number of dispatchers specified by the DISPATCHERS parameter and less than the number of processes specified by the PROCESSES parameter.

Basic

No

MAX_DISPATCHERS specifies the maximum number of dispatcher processes allowed to be running simultaneously. It can be overridden by the DISPATCHERS parameter and is maintained for backward compatibility with older releases.

See Also:

- Oracle Database Administrator's Guide for more information on setting this parameter

- Your operating system-specific Oracle documentation for the default value and range of values

MAX_DUMP_FILE_SIZE

Property

Description

Parameter type

String

Syntax

MAX_DUMP_FILE_SIZE = { integer [K | M | G] | UNLIMITED }

Default value

UNLIMITED

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

0 to unlimited, or UNLIMITED

Basic

No

MAX_DUMP_FILE_SIZE specifies the maximum size of trace files (excluding the alert file). Change this limit if you are concerned that trace files may use too much space.

- A numerical value for MAX_DUMP_FILE_SIZE specifies the maximum size in operating system blocks.

- A number followed by a K or M suffix specifies the file size in kilobytes or megabytes.

- The special value string UNLIMITED means that there is no upper limit on trace file size. Thus, dump files can be as large as the operating system permits.

See Also:

Oracle Database Administrator's Guide and Oracle Database Performance Tuning Guide for more information on setting this parameter

MAX_ENABLED_ROLES

Property

Description

Parameter type

Integer

Default value

30

Modifiable

No

Range of values

0 to 148

Basic

No

Note:

The MAX_ENABLED_ROLES parameter is deprecated. It is retained for backward compatibility only.

MAX_ENABLED_ROLES specifies the maximum number of database roles that users can enable, including roles contained within other roles. The actual number of roles that users can enable is 2 plus the value of MAX_ENABLED_ROLES, because each user has two additional roles, PUBLIC and the user's own role.

For example, if MAX_ENABLED_ROLES is set to 5, then user HR can have seven roles enabled (the five enabled by MAX_ENABLED_ROLES, plus PUBLIC and HR).

MAX_SHARED_SERVERS

Property

Description

Parameter type

Integer

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Range of values

If MAX_SHARED_SERVERS is specified, then it should be greater than or equal to SHARED_SERVERS and less than PROCESSES.

Basic

No

MAX_SHARED_SERVERS specifies the maximum number of shared server processes allowed to be running simultaneously. Setting this parameter enables you to reserve process slots for other processes, such as dedicated servers.

When you want to reduce the range of shared servers, you can reduce MAX_SHARED_SERVERS before reducing SHARED_SERVERS. If MAX_SHARED_SERVERS is lower than SHARED_SERVERS, then the number of shared servers will not vary but will remain at the constant level specified by SHARED_SERVERS. If MAX_SHARED_SERVERS is not specified, then a shared server process may be spawned as long as the number of free process slots is greater than 1 / 8 the maximum number of processes, or 2 if PROCESSES is less than 24.

MEMORY_MAX_TARGET

Property

Description

Parameter type

Big integer

Syntax

MEMORY_MAX_TARGET = integer [K | M | G]

Default value

0

Modifiable

No

Range of values

0 to the physical memory size available to the Oracle Database

Basic

No

MEMORY_MAX_TARGET specifies the maximum value to which a DBA can set the MEMORY_TARGET initialization parameter. See the description of MEMORY_TARGET for more information about how the settings of MEMORY_MAX_TARGET and MEMORY_TARGET affect each other.

See Also:

Oracle Database Administrator's Guide for more information about managing memory

MEMORY_TARGET

Property

Description

Parameter type

Big integer

Syntax

MEMORY_TARGET = integer [K | M | G]

Default value

0 (SGA autotuning is disabled for DEFERRED mode autotuning requests, but allowed for IMMEDIATE mode autotuning requests)

Modifiable

ALTER SYSTEM

Range of values

152 MB to MEMORY_MAX_TARGET

Basic

No

MEMORY_TARGET specifies the Oracle system-wide usable memory. The database tunes memory to the MEMORY_TARGET value, reducing or enlarging the SGA and PGA as needed.

In a text-based initialization parameter file, if you omit MEMORY_MAX_TARGET and include a value for MEMORY_TARGET, then the database automatically sets MEMORY_MAX_TARGET to the value of MEMORY_TARGET. If you omit the line for MEMORY_TARGET and include a value for MEMORY_MAX_TARGET, the MEMORY_TARGET parameter defaults to zero. After startup, you can then dynamically change MEMORY_TARGET to a nonzero value, provided that it does not exceed the value of MEMORY_MAX_TARGET.

Total memory usage can grow beyond the value of MEMORY_TARGET. For example, memory is allocated to PL/SQL tables and varrays regardless of the value of MEMORY_TARGET as long as memory is available at the operating system level.

In the Default value field, IMMEDIATE mode autotuning requests are necessary to avoid ORA-04031 errors. The DEFERRED and IMMEDIATE modes are reflected in the OPER_MODE column of the V$MEMORY_RESIZE_OPS view.

Note:

The default value of SGA_MAX_SIZE depends on the values of MEMORY_TARGET and MEMORY_MAX_TARGET.

Oracle Database Administrator's Guide for more information about managing memory

NLS_CALENDAR

Property

Description

Parameter type

String

Syntax

NLS_CALENDAR = "calendar_system"

Default value

None

Modifiable

ALTER SESSION

Range of values

Any valid calendar format name

Basic

No

NLS_CALENDAR specifies which calendar system Oracle uses. It can have one of the following values:

- Arabic Hijrah

- English Hijrah

- Gregorian

- Japanese Imperial

- Persian

- ROC Official (Republic of China)

- Thai Buddha

For example, suppose NLS_CALENDAR is set to "Japanese Imperial", the date format is "E YY-MM-DD". ("E" is the date format element for the abbreviated era name.) If the date is May 15, 1997, then the SYSDATE is displayed as follows:

SELECT SYSDATE FROM DUAL;
SYSDATE
--------
H 09-05-15

Note:

The value of this initialization parameter NLS_CALENDER is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined.

See Also:

NLS_COMP

Property

Description

Parameter type

String

Syntax

NLS_COMP = { BINARY | LINGUISTIC | ANSI }

Default value

BINARY

Modifiable

ALTER SESSION

Basic

No

NLS_COMP specifies the collation behavior of the database session.

Values:

- BINARY
Normally, comparisons in the WHERE clause and in PL/SQL blocks is binary unless you specify the NLSSORT function.

- LINGUISTIC
Comparisons for all SQL operations in the WHERE clause and in PL/SQL blocks should use the linguistic sort specified in the NLS_SORT parameter. To improve the performance, you can also define a linguistic index on the column for which you want linguistic comparisons.

- ANSI
A setting of ANSI is for backwards compatibility; in general, you should set NLS_COMP to LINGUISTIC

Note:

Unless you explicitly set the value for NLS_COMP in your initialization parameter file, a default value of NULL is shown in the following views: V$PARAMETER, V$SYSTEM_PARAMETER, V$PARAMETER2, V$SYSTEM_PARAMETER2, and NLS_INSTANCE_PARAMETERS. However, the actual default value, and behavior, is BINARY. Note that you cannot change the default to NULL, because NULL is not among the valid values.

Note:

The value of this initialization parameter NLS_COMP is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

Parameter type

String

Syntax

NLS_DATE_FORMAT = "format"

Default value

Derived from NLS_TERRITORY

Modifiable

ALTER SESSION

Range of values

Any valid date format mask but not exceeding a fixed length

Basic

No

NLS_DATE_FORMAT specifies the default date format to use with the TO_CHAR and TO_DATE functions. The default value of this parameter is determined by NLS_TERRITORY.

The value of this parameter can be any valid date format mask, and the value must be surrounded by double quotation marks. For example:

NLS_DATE_FORMAT = "MM/DD/YYYY"

Note:

The value of this initialization parameter NLS_DATE_FORMAT is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

Description

Parameter type

String

Syntax

NLS_DUAL_CURRENCY = currency_symbol

Default value

Derived from NLS_TERRITORY

Modifiable

ALTER SESSION

Range of values

Any valid format name up to 10 characters

NLS_DUAL_CURRENCY specifies the dual currency symbol (such as "Euro") for the territory. The default is the dual currency symbol defined in the territory of your current language environment.

Note:

The value of this initialization parameter NLS_DUAL_CURRENCY is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

NLS_ISO_CURRENCY

Property

Description

Parameter type

String

Syntax

NLS_ISO_CURRENCY = territory

Default value

Derived from NLS_TERRITORY

Modifiable

ALTER SESSION

Range of values

Any valid NLS_TERRITORY value

NLS_ISO_CURRENCY specifies the string to use as the international currency symbol for the C number format element.

Local currency symbols can be ambiguous. For example, a dollar sign ($) can refer to U.S. dollars or Australian dollars. ISO Specification 4217 1987-07-15 defines unique "international" currency symbols for the currencies of specific territories or countries.

Note:

The value of this initialization parameter NLS_ISO_CURRENCY is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

Parameter type

String

Syntax

NLS_LANGUAGE = language

Default value

Operating system-dependent, derived from the NLS_LANG environment variable

Modifiable

ALTER SESSION

Range of values

Any valid language name

Basic

Yes

NLS_LANGUAGE specifies the default language of the database. This language is used for messages, day and month names, symbols for AD, BC, a.m., and p.m., and the default sorting mechanism. This parameter also determines the default values of the parameters NLS_DATE_LANGUAGE and NLS_SORT.

Note:

The value of this initialization parameter NLS_LANGUAGE is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

NLS_LENGTH_SEMANTICS

Property

Description

Parameter type

String

Syntax

NLS_LENGTH_SEMANTICS = string
Example: NLS_LENGTH_SEMANTICS = 'CHAR'

Default value

BYTE

Modifiable

ALTER SESSION

Range of values

BYTE | CHAR

The session-level value of NLS_LENGTH_SEMANTICS specifies the default length semantics to use for VARCHAR2 and CHAR table columns, user-defined object attributes, and PL/SQL variables in database objects created in the session. This default may be overridden by the explicit length semantics qualifiers BYTE and CHAR in column, attribute, and variable definitions.

The instance-level value of NLS_LENGTH_SEMANTICS provides a default for the session-level value if NLS_LENGTH_SEMANTICS it is not set explicitly by the database client through the NLS_LENGTH_SEMANTICS client environment variable (does not apply to JDBC Thin clients), or the ALTER SESSION SET NLS_LENGTH_SEMANTICS statement.

NCHAR, NVARCHAR2, CLOB, and NCLOB columns are always character-based.

Sessions logged in as SYS do not use the NLS_LENGTH_SEMANTICS parameter. They use BYTE length semantics for all created objects unless overridden by the explicit BYTE and CHAR qualifiers in object definitions (SQL DDL statements).

Caution:

Oracle strongly recommends that you do NOT set the NLS_LENGTH_SEMANTICS parameter to CHAR in the instance or server parameter file. This may cause many existing installation scripts to unexpectedly create columns with character length semantics, resulting in runtime errors, including buffer overflows.

NLS_NCHAR_CONV_EXCP

Property

Description

Parameter type

String

Syntax

NLS_NCHAR_CONV_EXCP = { TRUE | FALSE }

Default value

FALSE

Modifiable

ALTER SESSION

NLS_NCHAR_CONV_EXCP determines whether an error is reported when there is data loss during an implicit or explicit character type conversion between NCHAR/NVARCHAR and CHAR/VARCHAR2. The default value results in no error being reported.

See Also:

Oracle Database Globalization Support Guide for more information on setting this parameter

NLS_NUMERIC_CHARACTERS

Property

Description

Parameter type

String

Syntax

NLS_NUMERIC_CHARACTERS =
"decimal_character group_separator"

Default value

Derived from NLS_TERRITORY

Modifiable

ALTER SESSION

NLS_NUMERIC_CHARACTERS specifies the characters to use as the group separator and decimal character. It overrides those characters defined implicitly by NLS_TERRITORY. The group separator separates integer groups (that is, thousands, millions, billions, and so on). The decimal separates the integer portion of a number from the decimal portion.

You can specify any character as the decimal or group separator. The two characters specified must be single-byte and must be different from each other. The characters cannot be any numeric character or any of the following characters: plus (+), minus sign (-), less than sign (<), greater than sign (>). Either character can be a space.

For example, if you wish to specify a comma as the decimal character and a space as the group separator, you would set this parameter as follows:

NLS_NUMERIC_CHARACTERS = ", "

Note:

The value of this initialization parameter NLS_NUMERIC_CHARACTERS is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

Oracle Database Globalization Support Guide for more information on setting this parameter

NLS_SORT

Property

Description

Parameter type

String

Syntax

NLS_SORT = { BINARY | linguistic_definition }

Default value

Derived from NLS_LANGUAGE

Modifiable

ALTER SESSION

Range of values

BINARY or any valid linguistic definition name

NLS_SORT specifies the collating sequence for character value comparison in various SQL operators and clauses, for example, ORDER BY, GROUP BY, comparison conditions (=, <>, <=, >=), IN, BETWEEN, LIKE, MIN/MAX, GREATEST/LEAST, and INSTR.

- If the value is BINARY, then comparison is based directly on byte values in the binary encoding of the character values being compared. The ordering depends on the character set of the compared values, which is either the database character set (for VARCHAR2, CHAR, LONG, and CLOB) or the national character set (for NVARCHAR2, NCHAR, and NCLOB).

- If the value is a named linguistic sort, then comparison is defined by this sort. A linguistic sort uses various rules to achieve ordering expected by speakers of one or more natural languages. This is usually the same ordering that is used in dictionaries and/or telephone directories in those languages.

The exact operators and query clauses that obey the NLS_SORT parameter depend on the value of the NLS_COMP parameter. If an operator or clause does not obey the NLS_SORT value, as determined by NLS_COMP, the collation used is BINARY.

The BINARY comparison is faster and uses less resources than any linguistic comparison but for text in a natural language, it does not provide ordering expected by users.

The value of NLS_SORT affects execution plans of queries. Because a standard index cannot be used as a source of values sorted in a linguistic order, an explicit sort operation must usually be performed instead of an index range scan. A functional index on the NLSSORT function may be defined to provide values sorted in a linguistic order and reintroduce the index range scan to the execution plan.

Note:

The value of the initialization parameter NLS_SORT is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overriden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

NLS_TERRITORY

Property

Description

Parameter type

String

Syntax

NLS_TERRITORY = territory

Default value

Operating system-dependent

Modifiable

ALTER SESSION

Range of values

Any valid territory name

Basic

Yes

NLS_TERRITORY specifies the name of the territory whose conventions are to be followed for day and week numbering.

This parameter also establishes the default date format, the default decimal character and group separator, and the default ISO and local currency symbols.

For information on these settings, see "NLS_DATE_FORMAT", "NLS_NUMERIC_CHARACTERS", "NLS_CURRENCY", and "NLS_ISO_CURRENCY".

Note:

The value of this initialization parameter NLS_TERRITORY is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

NLS_TIMESTAMP_FORMAT

Property

Description

Parameter type

String

Syntax

NLS_TIMESTAMP_FORMAT = "format"

Default value

Derived from NLS_TERRITORY

Modifiable

ALTER SESSION

Range of values

Any valid datetime format mask

NLS_TIMESTAMP_FORMAT defines the default timestamp format to use with the TO_CHAR and TO_TIMESTAMP functions.

The value must be surrounded by quotation marks as follows:

NLS_TIMESTAMP_FORMAT = 'YYYY-MM-DD HH:MI:SS.FF'

You can specify the value of NLS_TIMESTAMP_FORMAT by setting it in the initialization parameter file. You can specify its value for a client as a client environment variable.

You can also alter the value of NLS_TIMESTAMP_FORMAT by changing its value in the initialization parameter and then restarting the instance. To alter the value during a session use the ALTER SESSION SET statement.

Note:

The value of this initialization parameter NLS_TIMESTAMP_FORMAT is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

NLS_TIMESTAMP_TZ_FORMAT

Property

Description

Parameter type

String

Syntax

NLS_TIMESTAMP_TZ_FORMAT = "format"

Default value

Derived from NLS_TERRITORY

Modifiable

ALTER SESSION

Range of values

Any valid datetime format mask

NLS_TIMESTAMP_TZ_FORMAT defines the default timestamp with time zone format to use with the TO_CHAR and TO_TIMESTAMP_TZ functions.

The value must be surrounded by quotation marks as follows:

NLS_TIMESTAMP_TZ_FORMAT = 'YYYY-MM-DD HH:MI:SS.FF TZH:TZM'

You can specify the value of NLS_TIMESTAMP_TZ_FORMAT by setting it in the initialization parameter file. You can specify its value for a client as a client environment variable.

You can also alter the value of NLS_TIMESTAMP_TZ_FORMAT by changing its value in the initialization parameter and then restarting the instance. To alter the value during a session use the ALTER SESSION SET statement.

Note:

The value of this initialization parameter NLS_TIMESTAMP_TZ_FORMAT is used to initialize the session value of this parameter, which is the actual value referenced by the SQL query processing. This initial value is overridden by a client-side value if the client uses the Oracle JDBC driver or if the client is OCI-based and the NLS_LANG client setting (environment variable) is defined. The initialization parameter value is, therefore, usually ignored.

O7_DICTIONARY_ACCESSIBILITY

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

O7_DICTIONARY_ACCESSIBILITY controls restrictions on SYSTEM privileges. If the parameter is set to true, access to objects in the SYS schema is allowed (Oracle7 behavior). The default setting of false ensures that system privileges that allow access to objects in "any schema" do not allow access to objects in the SYS schema.

For example, if O7_DICTIONARY_ACCESSIBILITY is set to false, then the SELECT ANY TABLE privilege allows access to views or tables in any schema except the SYS schema (data dictionary tables cannot be accessed). The system privilege EXECUTE ANY PROCEDURE allows access on the procedures in any schema except the SYS schema.

If this parameter is set to false and you need to access objects in the SYS schema, then you must be granted explicit object privileges. The following roles, which can be granted to the database administrator, also allow access to dictionary objects:

- SELECT_CATALOG_ROLE

- EXECUTE_CATALOG_ROLE

- DELETE_CATALOG_ROLE

See Also:

- Oracle Database Upgrade Guide for more information on this parameter and the roles mentioned here

- Oracle Database SQL Language Reference for information on granting roles

OBJECT_CACHE_MAX_SIZE_PERCENT

Property

Description

Parameter type

Integer

Default value

10

Modifiable

ALTER SESSION, ALTER SYSTEM ... DEFERRED

Range of values

0 to operating system-dependent maximum

The object cache is a memory block on the client that allows applications to store entire objects and to navigate among them without round trips to the server. OBJECT_CACHE_MAX_SIZE_PERCENT specifies the percentage of the optimal cache size that the session object cache can grow past the optimal size. The maximum size is equal to the optimal size plus the product of this percentage and the optimal size. When the cache size exceeds this maximum size, the system will attempt to shrink the cache to the optimal size.

OBJECT_CACHE_OPTIMAL_SIZE

Property

Description

Parameter type

Integer

Default value

102400 (100K)

Modifiable

ALTER SESSION, ALTER SYSTEM ... DEFERRED

Range of values

10 KB to operating system-dependent maximum

The object cache is a memory block on the client that allows applications to store entire objects and to navigate among them without round trips to the server. OBJECT_CACHE_OPTIMAL_SIZE specifies (in bytes) the size to which the session object cache is reduced when the size of the cache exceeds the maximum size.

OLAP_PAGE_POOL_SIZE

Property

Description

Parameter type

Big integer

Syntax

OLAP_PAGE_POOL_SIZE = integer [K | M | G]

Default value

0

Modifiable

ALTER SESSION, ALTER SYSTEM ... DEFERRED

Range of values

0 to 2 GB

OLAP_PAGE_POOL_SIZE specifies (in bytes) the size of the OLAP page pool.

See Also:

OPEN_CURSORS

Property

Description

Parameter type

Integer

Default value

50

Modifiable

ALTER SYSTEM

Range of values

0 to 65535

Basic

Yes

OPEN_CURSORS specifies the maximum number of open cursors (handles to private SQL areas) a session can have at once. You can use this parameter to prevent a session from opening an excessive number of cursors.

It is important to set the value of OPEN_CURSORS high enough to prevent your application from running out of open cursors. The number will vary from one application to another. Assuming that a session does not open the number of cursors specified by OPEN_CURSORS, there is no added overhead to setting this value higher than actually needed.

- Your operating system-specific Oracle documentation for the range of values

OPEN_LINKS

Property

Description

Parameter type

Integer

Default value

4

Modifiable

No

Range of values

0 to 255

OPEN_LINKS specifies the maximum number of concurrent open connections to remote databases in one session. These connections include database links, as well as external procedures and cartridges, each of which uses a separate process.

Oracle counts one open link for the following:

- For each user that references a public or private database link

- For each external procedure or cartridge connection when it is executed for the first time

Both types of connections close when the session ends. You can also close a database link connection explicitly by issuing an ALTER SESSION CLOSE DATABASE LINK statement.

You should set this parameter to allow for the external procedure and cartridge connections expected during the session plus the number of databases referred to in typical distributed transactions (that is, a single SQL statement that references multiple databases), so that all the databases can be open to execute the statement. For example, if queries alternately access databases A, B, and C, and OPEN_LINKS is set to 2, time will be lost waiting while one connection is broken and another made. Increase the value if many different databases are accessed over time.

This parameter refers only to connections used for distributed transactions. Direct connections to a remote database specified as an application connects are not counted.

If you set OPEN_LINKS to 0, then no distributed transactions are allowed.

See Also:

"OPEN_LINKS_PER_INSTANCE" for information on setting open connections globally for a database instance

OPEN_LINKS_PER_INSTANCE

Property

Description

Parameter type

Integer

Default value

4

Modifiable

No

Range of values

0 to 4294967295 (4 GB -1)

Oracle RAC

Multiple instances can have different values.

OPEN_LINKS_PER_INSTANCE specifies the maximum number of migratable open connections globally for each database instance. XA transactions use migratable open connections so that the connections are cached after a transaction is committed. Another transaction can use the connection, provided the user who created the connection is the same as the user who owns the transaction.

OPEN_LINKS_PER_INSTANCE is different from OPEN_LINKS, which indicates the number of connections from a session. The OPEN_LINKS parameter is not applicable to XA applications.

OPTIMIZER_FEATURES_ENABLE

Property

Description

Parameter type

String

Syntax

OPTIMIZER_FEATURES_ENABLE = { 8.0.0 | 8.0.3 | 8.0.4 | 8.0.5 | 8.0.6 | 8.0.7 | 8.1.0 | 8.1.3 | 8.1.4 | 8.1.5 | 8.1.6 | 8.1.7 | 9.0.0 | 9.0.1 | 9.2.0 | 9.2.0.8 | 10.1.0 | 10.1.0.3 | 10.1.0.4 | 10.1.0.5 | 10.2.0.1 | 10.2.0.2 | 10.2.0.3 | 10.2.0.4 | 10.2.0.5 | 11.1.0.6 | 11.1.0.7 | 11.2.0.1 }

Default value

11.2.0.1

Modifiable

ALTER SESSION, ALTER SYSTEM

OPTIMIZER_FEATURES_ENABLE acts as an umbrella parameter for enabling a series of optimizer features based on an Oracle release number.

For example, if you upgrade your database from release 10.1 to release 11.1, but you want to keep the release 10.1 optimizer behavior, you can do so by setting this parameter to 10.1.0. At a later time, you can try the enhancements introduced in releases up to and including release 11.1 by setting the parameter to 11.1.0.6.

Table 1-3 describes some of the optimizer features that are enabled when you set the OPTIMIZER_FEATURES_ENABLE parameter to a 9.0 release or a 9.2 release.

Table 1-4 describes some of the optimizer features that are enabled when you set the OPTIMIZER_FEATURES_ENABLE parameter to a 10.1 release or a 10.2 release.

Table 1-5 describes some of the optimizer features that are enabled when you set the OPTIMIZER_FEATURES_ENABLE parameter to a 11.1 release.

OPTIMIZER_INDEX_CACHING

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

0 to 100

OPTIMIZER_INDEX_CACHING lets you adjust the behavior of cost-based optimization to favor nested loops joins and IN-list iterators.

The cost of executing an index using an IN-list iterator or of executing a nested loops join when an index is used to access the inner table depends on the caching of that index in the buffer cache. The amount of caching depends on factors that the optimizer cannot predict, such as the load on the system and the block access patterns of different users.

You can modify the optimizer's assumptions about index caching for nested loops joins and IN-list iterators by setting this parameter to a value between 0 and 100 to indicate the percentage of the index blocks the optimizer should assume are in the cache. Setting this parameter to a higher value makes nested loops joins and IN-list iterators look less expensive to the optimizer. As a result, it will be more likely to pick nested loops joins over hash or sort-merge joins and to pick indexes using IN-list iterators over other indexes or full table scans. The default for this parameter is 0, which results in default optimizer behavior.

Oracle Database Performance Tuning Guide for more information on setting this parameter

OPTIMIZER_INDEX_COST_ADJ

Property

Description

Parameter type

Integer

Default value

100

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

1 to 10000

OPTIMIZER_INDEX_COST_ADJ lets you tune optimizer behavior for access path selection to be more or less index friendly—that is, to make the optimizer more or less prone to selecting an index access path over a full table scan.

The default for this parameter is 100 percent, at which the optimizer evaluates index access paths at the regular cost. Any other value makes the optimizer evaluate the access path at that percentage of the regular cost. For example, a setting of 50 makes the index access path look half as expensive as normal.

Note:

The adjustment does not apply to user-defined cost functions for domain indexes.

Oracle Database Performance Tuning Guide for more information on setting this parameter, and on its relationship to "OPTIMIZER_INDEX_CACHING"

OPTIMIZER_MODE

Property

Description

Parameter type

String

Syntax

OPTIMIZER_MODE =
{ first_rows_[1 | 10 | 100 | 1000] | first_rows | all_rows }

Default value

all_rows

Modifiable

ALTER SESSION, ALTER SYSTEM

OPTIMIZER_MODE establishes the default behavior for choosing an optimization approach for the instance.

Values:

- first_rows_n
The optimizer uses a cost-based approach and optimizes with a goal of best response time to return the first n rows (where n = 1, 10, 100, 1000).

- first_rows
The optimizer uses a mix of costs and heuristics to find a best plan for fast delivery of the first few rows.

- all_rows
The optimizer uses a cost-based approach for all SQL statements in the session and optimizes with a goal of best throughput (minimum resource use to complete the entire statement).

OPTIMIZER_SECURE_VIEW_MERGING

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SYSTEM

Range of values

true | false

Basic

No

Oracle RAC

Multiple instances can have different values

OPTIMIZER_SECURE_VIEW_MERGING enables the optimizer to use view merging to improve query performance without performing the checks that would otherwise be performed to ensure that view merging does not violate any security intentions of the view creator.

Values:

- false
Oracle does not perform security checks that may prevent view merging and predicate move-around.

- true
Oracle performs checks to ensure that view merging and predicate move-around do not violate any security intentions of the view creator.

To take advantage of query rewrite for a particular query, you must disable the OPTIMIZER_SECURE_VIEW_MERGING parameter.

OPTIMIZER_USE_INVISIBLE_INDEXES

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

OPTIMIZER_USE_INVISIBLE_INDEXES enables or disables the use of invisible indexes.

Values:

- true
Invisible indexes are treated as visible (normal) indexes.

- false
Invisible indexes will not be considered by the optimizer but will still be maintained by DML operations.

OPTIMIZER_USE_PENDING_STATISTICS

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

OPTIMIZER_USE_PENDING_STATISTICS specifies whether or not the optimizer uses pending statistics when compiling SQL statements.

See Also:

Oracle Database Performance Tuning Guide for more information on setting this parameter

OPTIMIZER_USE_SQL_PLAN_BASELINES

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

OPTIMIZER_USE_SQL_PLAN_BASELINES enables or disables the use of SQL plan baselines stored in SQL Management Base. When enabled, the optimizer looks for a SQL plan baseline for the SQL statement being compiled. If one is found in SQL Management Base, then the optimizer will cost each of the baseline plans and pick one with the lowest cost.

OS_AUTHENT_PREFIX

Property

Description

Parameter type

String

Syntax

OS_AUTHENT_PREFIX = authentication_prefix

Default value

OPS$

Modifiable

No

OS_AUTHENT_PREFIX specifies a prefix that Oracle uses to authenticate users attempting to connect to the server. Oracle concatenates the value of this parameter to the beginning of the user's operating system account name and password. When a connection request is attempted, Oracle compares the prefixed username with Oracle usernames in the database.

The default value of this parameter is OPS$ for backward compatibility with previous versions. However, you might prefer to set the prefix value to "" (a null string), thereby eliminating the addition of any prefix to operating system account names.

Note:

The text of the OS_AUTHENT_PREFIX parameter is case sensitive on some operating systems.

See Also:

- Oracle Database Advanced Security Administrator's Guide for more information on setting this parameter

- Your operating system-specific Oracle documentation for the default value

OS_ROLES

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

OS_ROLES determines whether Oracle or the operating system identifies and manages the roles of each username.

Values:

- TRUE
The operating system completely manages the role grants for all database usernames. When a user attempts to create a session, the username's security domain is initialized using the roles identified by the operating system. A user can subsequently enable as many roles identified by the operating system as specified by the parameter MAX_ENABLED_ROLES.

Revocation by Oracle of roles granted by the operating system is ignored, as are any roles previously granted by Oracle.

- FALSE
Oracle identifies and manages the roles.

- Oracle Database Administrator's Guide and Oracle Database Advanced Security Administrator's Guide for more information on roles and on setting this parameter

- "REMOTE_OS_ROLES"

PARALLEL_ADAPTIVE_MULTI_USER

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SYSTEM

Range of values

true | false

PARALLEL_ADAPTIVE_MULTI_USER, when set to true, enables an adaptive algorithm designed to improve performance in multiuser environments that use parallel execution. The algorithm automatically reduces the requested degree of parallelism based on the system load at query startup time. The effective degree of parallelism is based on the default degree of parallelism, or the degree from the table or hints, divided by a reduction factor.

The algorithm assumes that the system has been tuned for optimal performance in a single-user environment.

Tables and hints use the default degree of parallelism.

See Also:

Oracle Database Performance Tuning Guide for more information on tuning parallel execution and on the algorithm described here

PARALLEL_AUTOMATIC_TUNING

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

Note:

The PARALLEL_AUTOMATIC_TUNING parameter is deprecated. It is retained for backward compatibility only.

When PARALLEL_AUTOMATIC_TUNING is set to true, Oracle determines the default values for parameters that control parallel execution. In addition to setting this parameter, you must specify the PARALLEL clause for the target tables in the system. Oracle then tunes all subsequent parallel operations automatically.

If you used parallel execution in a previous release and are now enabling PARALLEL_AUTOMATIC_TUNING, then you should reduce the amount of memory allocated from the shared pool to account for the decreased demand on that pool. This memory will now be allocated from the large pool, and will be computed automatically if LARGE_POOL_SIZE is not specified.

As part of the automatic tuning, Oracle will enable the PARALLEL_ADAPTIVE_MULTI_USER parameter. You can override any of the system-provided defaults if desired.

PARALLEL_DEGREE_LIMIT

Property

Description

Parameter type

String

Syntax

PARALLEL_DEGREE_LIMIT = { CPU | IO | integer }

Default value

CPU

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

With automatic degree of parallelism, Oracle automatically decides whether or not a statement should execute in parallel and what degree of parallelism the statement should use. The optimizer automatically determines the degree of parallelism for a statement based on the resource requirements of the statement. However, the optimizer will limit the degree of parallelism used to ensure parallel server processes do not flood the system. This limit is enforced by PARALLEL_DEGREE_LIMIT.

Values:

- CPU
The maximum degree of parallelism is limited by the number of CPUs in the system. The formula used to calculate the limit is PARALLEL_THREADS_PER_CPU * CPU_COUNT * the number of instances available (by default, all the opened instances on the cluster but can be constrained using PARALLEL_INSTANCE_GROUP or service specification). This is the default.

- IO
The maximum degree of parallelism the optimizer can use is limited by the I/O capacity of the system. The value is calculated by dividing the total system throughput by the maximum I/O bandwidth per process. You must run the DBMS_RESOURCE_MANAGER.CALIBRATE_IO procedure on the system in order to use the IO setting. This procedure will calculate the total system throughput and the maximum I/O bandwidth per process.

- integer
A numeric value for this parameter specifies the maximum degree of parallelism the optimizer can choose for a SQL statement when automatic degree of parallelism is active. Automatic degree of parallelism is only enabled if PARALLEL_DEGREE_POLICY is set to AUTO or LIMITED.

See Also:

- Oracle Database VLDB and Partitioning Guide for information about automatic degree of parallelism

- Oracle Database PL/SQL Packages and Types Reference for information on the DBMS_RESOURCE_MANAGER.CALIBRATE_IO procedure

PARALLEL_DEGREE_POLICY

Property

Description

Parameter type

String

Syntax

PARALLEL_DEGREE_POLICY = { MANUAL | LIMITED | AUTO }

Default value

MANUAL

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

PARALLEL_DEGREE_POLICY specifies whether or not automatic degree of Parallelism, statement queuing, and in-memory parallel execution will be enabled.

Values:

- MANUAL
Disables automatic degree of parallelism, statement queuing, and in-memory parallel execution. This reverts the behavior of parallel execution to what it was prior to Oracle Database 11g Release 2 (11.2). This is the default.

- LIMITED
Enables automatic degree of parallelism for some statements but statement queuing and in-memory Parallel Execution are disabled. Automatic degree of parallelism is only applied to those statements that access tables or indexes decorated explicitly with the DEFAULT degree of parallelism using the PARALLEL clause. Statements that do not access any tables or indexes decorated with the DEFAULT degree of parallelism will retain the MANUAL behavior.

- AUTO
Enables automatic degree of parallelism, statement queuing, and in-memory parallel execution.

See Also:

Oracle Database VLDB and Partitioning Guide for information about automatic degree of parallelism, statement queuing, and in-memory parallel execution

PARALLEL_EXECUTION_MESSAGE_SIZE

Property

Description

Parameter type

Integer

Default value

Operating system-dependent

Modifiable

No

Range of values

Minimum: 2148
Maximum: 32768, but some operating systems may have a smaller value

Oracle RAC

Multiple instances must have the same value.

PARALLEL_EXECUTION_MESSAGE_SIZE specifies the size of messages used for parallel execution (formerly referred to as parallel query, PDML, Parallel Recovery, replication).

On most platforms, the default value is as follows:

- 16384 bytes if COMPATIBLE is set to 11.2.0 or higher

- 4096 bytes if COMPATIBLE is less than 11.2.0 and PARALLEL_AUTOMATIC_TUNING is set to true

- 2148 bytes if COMPATIBLE is less than 11.2.0 and PARALLEL_AUTOMATIC_TUNING is set to false

The default value is adequate for most applications. Larger values require a larger shared pool. Larger values result in better performance at the cost of higher memory use. For this reason, replication gets no benefit from increasing the size.

Note:

When PARALLEL_AUTOMATIC_TUNING is set to TRUE, message buffers are allocated out of the large pool. In this case, the default is generally higher. Note that the PARALLEL_AUTOMATIC_TUNING parameter has been deprecated.

PARALLEL_FORCE_LOCAL

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

PARALLEL_FORCE_LOCAL controls parallel execution in an Oracle RAC environment. By default, the parallel server processes selected to execute a SQL statement can operate on any or all Oracle RAC nodes in the cluster. By setting PARALLEL_FORCE_LOCAL to true, the parallel server processes are restricted so that they can only operate on the same Oracle RAC node where the query coordinator resides (the node on which the SQL statement was executed on).

PARALLEL_INSTANCE_GROUP

Property

Description

Parameter type

String

Syntax

PARALLEL_INSTANCE_GROUP = service_name | group_name

Default value

There is no default value; parallel execution is enabled across all currently active instances.

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

Any service name or any group name specified in the INSTANCE_GROUPS parameter of any active instance

Oracle RAC

Multiple instances can have different values.

PARALLEL_INSTANCE_GROUP is an Oracle RAC parameter that you can specify in parallel mode only. Used in conjunction with services or with the INSTANCE_GROUPS parameter, it lets you restrict parallel query operations to a limited number of instances. Note that the INSTANCE_GROUPS parameter has been deprecated.

This parameter identifies the parallel instance group Oracle will use for spawning parallel execution processes. If used in conjunction with services, then parallel operations will spawn parallel execution processes only on instances defined in the service. If used in conjunction with INSTANCE_GROUPS, then parallel operations will spawn parallel execution processes only on instances that specify a matching group in their INSTANCE_GROUPS parameter.

If the value assigned to PARALLEL_INSTANCE_GROUP is the name of a service or group that does not exist, then the operation runs serially. No parallelism is used.

See Also:

Oracle Real Application Clusters Administration and Deployment Guide for more information on parallel query execution in a Real Application Clusters environment

PARALLEL_IO_CAP_ENABLED

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Basic

No

Oracle RAC

Multiple instances can have different values.

Note:

The PARALLEL_IO_CAP_ENABLED parameter is deprecated. It is retained for backward compatibility only. It is replaced by the PARALLEL_DEGREE_LIMIT parameter when set to IO.

PARALLEL_IO_CAP_ENABLED specifies whether or not Oracle caps the default degree of parallelism to no greater than what the I/O system can support. This new value is calculated based on the results of the resource manager's I/O calibration package.

If PARALLEL_IO_CAP_ENABLED is set to true and the database I/O capacity has been calibrated, then Oracle will reduce the default degree of parallelism if the I/O capacity cannot support the available number of CPUs. To calibrate the I/O capacity, use the DBMS_RESOURCE_MANAGER.CALIBRATE_IO procedure to measure the system's I/O capacity. Oracle then computes the degree of parallelism so as not to exceed the system's I/O capacity.

See Also:

Oracle Database Data Warehousing Guide for information on initializing and tuning parameters for parallel execution

PARALLEL_MAX_SERVERS

Property

Description

Parameter type

Integer

Default value

PARALLEL_THREADS_PER_CPU * CPU_COUNT * concurrent_parallel_users * 5

Modifiable

ALTER SYSTEM

Range of values

0 to 3600

Oracle RAC

Multiple instances can have different values.

Note:

This parameter applies to parallel execution in exclusive mode as well as in a Real Application Clusters environment.

PARALLEL_MAX_SERVERS specifies the maximum number of parallel execution processes and parallel recovery processes for an instance. As demand increases, Oracle Database increases the number of processes from the number created at instance startup up to this value.

In the formula, the value assigned to concurrent_parallel_users running at the default degree of parallelism on an instance is dependent on the memory management setting. If automatic memory management is disabled (manual mode), then the value of concurrent_parallel_users is 1. If PGA automatic memory management is enabled, then the value of concurrent_parallel_users is 2. If global memory management or SGA memory target is used in addition to PGA automatic memory management, then the value of concurrent_parallel_users is 4.

If you set this parameter too low, then some queries may not have a parallel execution process available to them during query processing. If you set it too high, then memory resource shortages may occur during peak periods, which can degrade performance.

See Also:

Oracle Database Performance Tuning Guide for more information on tuning parallel execution

PARALLEL_MIN_PERCENT

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SESSION

Range of values

0 to 100

Oracle RAC

Multiple instances can have different values.

PARALLEL_MIN_PERCENT lets you specify the minimum percentage of the requested number of parallel execution processes required for parallel execution. Setting this parameter ensures that parallel operations will not execute unless adequate resources are available. The default value of 0 means that no minimum percentage of processes has been set.

Consider the following settings:

PARALLEL_MIN_PERCENT = 50
PARALLEL_MIN_SERVERS = 5
PARALLEL_MAX_SERVERS = 10

If 8 of the 10 parallel execution processes are busy, only 2 processes are available. If you then request a query with a degree of parallelism of 8, the minimum 50% will not be met.

You can use this parameter in conjunction with PARALLEL_ADAPTIVE_MULTI_USER. In a multi-user environment, an individual user or application can set PARALLEL_MIN_PERCENT to a minimum value until sufficient resources are available on the system and an acceptable degree of parallelism is returned.

See Also:

- Oracle Database Performance Tuning Guide for more information on tuning parallel execution

- "PARALLEL_MAX_SERVERS", "PARALLEL_MIN_SERVERS", and "PARALLEL_ADAPTIVE_MULTI_USER"

PARALLEL_MIN_SERVERS

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SYSTEM

Range of values

0 to value of PARALLEL_MAX_SERVERS

Oracle RAC

Multiple instances can have different values.

Note:

This parameter applies to parallel execution in exclusive mode as well as in a Real Application Clusters environment.

PARALLEL_MIN_SERVERS specifies the minimum number of parallel execution processes for the instance. This value is the number of parallel execution processes Oracle creates when the instance is started.

See Also:

Oracle Database Performance Tuning Guide for more information on tuning parallel execution

PARALLEL_MIN_TIME_THRESHOLD

Property

Description

Parameter type

String

Syntax

PARALLEL_MIN_TIME_THRESHOLD = { AUTO | integer }

Default value

AUTO

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

PARALLEL_MIN_TIME_THRESHOLD specifies the minimum execution time a statement should have before the statement is considered for automatic degree of parallelism. By default, this is set to 10 seconds. Automatic degree of parallelism is only enabled if PARALLEL_DEGREE_POLICY is set to AUTO or LIMITED.

See Also:

Oracle Database VLDB and Partitioning Guide for information about automatic degree of parallelism

PARALLEL_SERVERS_TARGET

Property

Description

Parameter type

Integer

Default value

PARALLEL_THREADS_PER_CPU * CPU_COUNT * concurrent_parallel_users * 2

Modifiable

ALTER SYSTEM

Range of values

0 to PARALLEL_MAX_SERVERS

Basic

No

PARALLEL_SERVERS_TARGET specifies the number of parallel server processes allowed to run parallel statements before statement queuing will be used. When the parameter PARALLEL_DEGREE_POLICY is set to AUTO, Oracle will queue SQL statements that require parallel execution, if the necessary parallel server processes are not available. Statement queuing will begin once the number of parallel server processes active on the system is equal to or greater than PARALLEL_SERVERS_TARGET.

By default, PARALLEL_SERVERS_TARGET is set lower than the maximum number of parallel server processes allowed on the system (PARALLEL_MAX_SERVERS) to ensure each parallel statement will get all of the parallel server resources required and to prevent overloading the system with parallel server processes.

The number of concurrent parallel users running at default degree of parallelism on an instance is dependent on the memory management setting. If automatic memory management is disabled (manual mode), then the number of concurrent parallel users is 1. If PGA automatic memory management is enabled, the number of concurrent parallel users is 2. If global memory management or SGA memory target is used in addition to PGA automatic memory management, then the number of concurrent parallel users is 4.

Note that all serial (non-parallel) statements will execute immediately even if statement queuing has been activated.

PARALLEL_THREADS_PER_CPU

Property

Description

Parameter type

Integer

Default value

Operating system-dependent, usually 2

Modifiable

ALTER SYSTEM

Range of values

Any nonzero number

Note:

This parameter applies to parallel execution in exclusive mode as well as in a Real Application Clusters environment.

PARALLEL_THREADS_PER_CPU specifies the default degree of parallelism for the instance and determines the parallel adaptive and load balancing algorithms. The parameter describes the number of parallel execution processes or threads that a CPU can handle during parallel execution.

The default is platform-dependent and is adequate in most cases. You should decrease the value of this parameter if the machine appears to be overloaded when a representative parallel query is executed. You should increase the value if the system is I/O bound.

PGA_AGGREGATE_TARGET

Property

Description

Parameter type

Big integer

Syntax

PGA_AGGREGATE_TARGET = integer [K | M | G]

Default value

10 MB or 20% of the size of the SGA, whichever is greater

Modifiable

ALTER SYSTEM

Range of values

Minimum: 10 MB
Maximum: 4096 GB - 1

Basic

Yes

PGA_AGGREGATE_TARGET specifies the target aggregate PGA memory available to all server processes attached to the instance.

Setting PGA_AGGREGATE_TARGET to a nonzero value has the effect of automatically setting the WORKAREA_SIZE_POLICY parameter to AUTO. This means that SQL working areas used by memory-intensive SQL operators (such as sort, group-by, hash-join, bitmap merge, and bitmap create) will be automatically sized. A nonzero value for this parameter is the default since, unless you specify otherwise, Oracle sets it to 20% of the SGA or 10 MB, whichever is greater.

Setting PGA_AGGREGATE_TARGET to 0 automatically sets the WORKAREA_SIZE_POLICY parameter to MANUAL. This means that SQL workareas are sized using the *_AREA_SIZE parameters.

Oracle attempts to keep the amount of private memory below the target specified by this parameter by adapting the size of the work areas to private memory. When increasing the value of this parameter, you indirectly increase the memory allotted to work areas. Consequently, more memory-intensive operations are able to run fully in memory and less will work their way over to disk.

See Also:

Oracle Database Performance Tuning Guide for more information about setting and tuning the PGA_AGGREGATE_TARGET parameter

PLSCOPE_SETTINGS

Property

Description

Parameter type

String

Syntax

PLSCOPE_SETTINGS = IDENTIFIERS:{ NONE | ALL }

Default value

IDENTIFIERS:NONE

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

PLSCOPE_SETTINGS controls the compile time collection, cross reference, and storage of PL/SQL source code identifier data.

Values:

- IDENTIFIERS:NONE
Disables collection of identifier data. This is the default.

- IDENTIFIERS:ALL
Enables the collection of all source code identifier data.

PLSCOPE_SETTINGS can be set on a session, system, or per-library unit (ALTER COMPILE) basis. The current setting of PLSCOPE_SETTINGS for any library unit can be attained by querying the *_PLSQL_OBJECT_SETTINGS views. Any identifier data collected by setting this parameter can be accessed using the *_IDENTIFIERS views.

See Also:

- "ALL_PLSQL_OBJECT_SETTINGS", "DBA_PLSQL_OBJECT_SETTINGS", and "USER_PLSQL_OBJECT_SETTINGS"

- "ALL_IDENTIFIERS", "DBA_IDENTIFIERS", and "USER_IDENTIFIERS"

PLSQL_CCFLAGS

Property

Description

Parameter type

String

Syntax

PLSQL_CCFLAGS = '<v1>:<c1>,<v2>:<c2>,...,<vn>:<cn>'

Default value

Empty string

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

Any string literal that satisfies the internal syntax

Examples

ALTER SESSION SET PLSQL_CCFLAGS = 'DeBug:TruE';
ALTER SESSION SET PLSQL_CCFLAGS = 'debug:TRUE';

PLSQL_CCFLAGS provides a mechanism that allows PL/SQL programmers to control conditional compilation of each PL/SQL library unit independently.

Values:

- <vi> has the form of an unquoted PL/SQL identifier. It is unrestricted and can be a reserved word or a keyword. The text is insensitive to case. Each one is known as a flag or flag name. Each <vi> can occur more than once in the string, each occurrence can have a different flag value, and the flag values can be of different kinds.

- <ci> is one of the following: a PL/SQL boolean literal, a PLS_INTEGER literal, or the literal NULL. The text is insensitive to case. Each one is known as a flag value and corresponds to a flag name.

You can define any allowable value for PLSQL_CCFLAGS. However, Oracle recommends that this parameter be used for controlling the conditional compilation of debugging or tracing code. It is recommended that the following identifiers not be used as flag name values:

- Names of Oracle parameters (for example, NLS_LENGTH_SEMANTICS)

- Identifiers with any of the following prefixes: PLS_, PLSQL_, PLSCC_, ORA_, ORACLE_, DBMS_, SYS_

PLSQL_CODE_TYPE

Property

Description

Parameter type

String

Syntax

PLSQL_CODE_TYPE = { INTERPRETED | NATIVE }

Default value

INTERPRETED

Modifiable

ALTER SESSION, ALTER SYSTEM

PLSQL_CODE_TYPE specifies the compilation mode for PL/SQL library units.

Values:

- INTERPRETED
PL/SQL library units will be compiled to PL/SQL bytecode format. Such modules are executed by the PL/SQL interpreter engine.

- NATIVE
PL/SQL library units (with the possible exception of top-level anonymous PL/SQL blocks) will be compiled to native (machine) code. Such modules will be executed natively without incurring any interpreter overhead.

When the value of this parameter is changed, it has no effect on PL/SQL library units that have already been compiled. The value of this parameter is stored persistently with each library unit.

If a PL/SQL library unit is compiled native, all subsequent automatic recompilations of that library unit will use native compilation.

PLSQL_DEBUG

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Note:

The PLSQL_DEBUG parameter is deprecated. It is retained for backward compatibility only.

PLSQL_DEBUG specifies whether or not PL/SQL library units will be compiled for debugging.

Values:

- true
PL/SQL library units will be compiled for debugging

- false
PL/SQL library units will be compiled for normal execution

When PLSQL_DEBUG is set to true, PL/SQL library units are always compiled INTERPRETED in order to be debuggable.

When the value of this parameter is changed, it has no effect on PL/SQL library units that have already been compiled. The value of this parameter is stored persistently with each library unit.

PLSQL_OPTIMIZE_LEVEL

Property

Description

Parameter type

Integer

Default value

2

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

0 to 3

PLSQL_OPTIMIZE_LEVEL specifies the optimization level that will be used to compile PL/SQL library units. The higher the setting of this parameter, the more effort the compiler makes to optimize PL/SQL library units.

Values:

- 0
Maintains the evaluation order and hence the pattern of side effects, exceptions, and package initializations of Oracle9i and earlier releases. Also removes the new semantic identity of BINARY_INTEGER and PLS_INTEGER and restores the earlier rules for the evaluation of integer expressions. Although code will run somewhat faster than it did in Oracle9i, use of level 0 will forfeit most of the performance gains of PL/SQL in Oracle Database 10g.

- 1
Applies a wide range of optimizations to PL/SQL programs including the elimination of unnecessary computations and exceptions, but generally does not move source code out of its original source order.

- 2
Applies a wide range of modern optimization techniques beyond those of level 1 including changes which may move source code relatively far from its original location.

- 3
Applies a wide range of optimization techniques beyond those of level 2, automatically including techniques not specifically requested.

Generally, setting this parameter to 2 pays off in better execution performance. If, however, the compiler runs slowly on a particular source module or if optimization does not make sense for some reason (for example, during rapid turnaround development), then setting this parameter to 1 will result in almost as good a compilation with less use of compile-time resources.

The value of this parameter is stored persistently with the library unit.

PLSQL_V2_COMPATIBILITY

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

Note:

The PLSQL_V2_COMPATIBILITY parameter is deprecated. It is retained for backward compatibility only.

PL/SQL Version 2 allows some abnormal behavior that Version 8 disallows. If you want to retain that behavior for backward compatibility, set PLSQL_V2_COMPATIBILITY to true. If you set it to false, then PL/SQL Version 8 behavior is enforced and Version 2 behavior is not allowed.

See Also:

Oracle Database PL/SQL Language Reference for a description of the differences between PL/SQL Version 2 and Version 8, and for more information on setting this parameter

PLSQL_WARNINGS

Property

Description

Parameter type

String

Syntax

PLSQL_WARNINGS = 'value_clause' [, 'value_clause' ] ...

value_clause::=
{ ENABLE | DISABLE | ERROR }:

{ ALL

| SEVERE

| INFORMATIONAL

| PERFORMANCE

| { integer

| (integer [, integer ] ...)

}

}

Default value

'DISABLE:ALL'

Modifiable

ALTER SESSION, ALTER SYSTEM

Examples

PLSQL_WARNINGS = 'ENABLE:SEVERE', 'DISABLE:INFORMATIONAL';
PLSQL_WARNINGS = 'DISABLE:ALL';
PLSQL_WARNINGS = 'DISABLE:5000', 'ENABLE:5001', 'ERROR:5002';
PLSQL_WARNINGS = 'ENABLE:(5000,5001,5002)', 'DISABLE:(6000,6001)';

PLSQL_WARNINGS enables or disables the reporting of warning messages by the PL/SQL compiler, and specifies which warning messages to show as errors.

value_clause

Multiple value clauses may be specified, enclosed in quotes and separated by commas. Each value clause is composed of a qualifier, a colon (:), and a modifier.

Qualifier values:

- ENABLE
Enable a specific warning or a set of warnings

- DISABLE
Disable a specific warning or a set of warnings

- ERROR
Treat a specific warning or a set of warnings as errors

Modifier values:

- ALL
Apply the qualifier to all warning messages

- SEVERE
Apply the qualifier to only those warning messages in the SEVERE category

- INFORMATIONAL
Apply the qualifier to only those warning messages in the INFORMATIONAL category

- PERFORMANCE
Apply the qualifier to only those warning messages in the PERFORMANCE category

PRE_PAGE_SGA

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

PRE_PAGE_SGA determines whether Oracle reads the entire SGA into memory at instance startup. Operating system page table entries are then prebuilt for each page of the SGA. This setting can increase the amount of time necessary for instance startup, but it is likely to decrease the amount of time necessary for Oracle to reach its full performance capacity after startup.

Note:

This setting does not prevent your operating system from paging or swapping the SGA after it is initially read into memory.

PRE_PAGE_SGA can increase the process startup duration, because every process that starts must access every page in the SGA. The cost of this strategy is fixed; however, you might simply determine that 20,000 pages must be touched every time a process starts. This approach can be useful with some applications, but not with all applications. Overhead can be significant if your system frequently creates and destroys processes by, for example, continually logging on and logging off.

The advantage that PRE_PAGE_SGA can afford depends on page size. For example, if the SGA is 80 MB in size and the page size is 4 KB, then 20,000 pages must be touched to refresh the SGA (80,000/4 = 20,000).

If the system permits you to set a 4 MB page size, then only 20 pages must be touched to refresh the SGA (80,000/4,000 = 20). The page size is operating system-specific and generally cannot be changed. Some operating systems, however, have a special implementation for shared memory whereby you can change the page size.

PROCESSES

Property

Description

Parameter type

Integer

Default value

100

Modifiable

No

Range of values

6 to operating system dependent

Basic

Yes

Oracle RAC

Multiple instances can have different values.

PROCESSES specifies the maximum number of operating system user processes that can simultaneously connect to Oracle. Its value should allow for all background processes such as locks, job queue processes, and parallel execution processes.

The default values of the SESSIONS and TRANSACTIONS parameters are derived from this parameter. Therefore, if you change the value of PROCESSES, you should evaluate whether to adjust the values of those derived parameters.

QUERY_REWRITE_ENABLED

Property

Description

Parameter type

String

Syntax

QUERY_REWRITE_ENABLED = { false | true | force }

Default value

If OPTIMIZER_FEATURES_ENABLE is set to 10.0.0 or higher, then true
If OPTIMIZER_FEATURES_ENABLE is set to 9.2.0 or lower, then false

Modifiable

ALTER SESSION, ALTER SYSTEM

Oracle RAC

Multiple instances can have different values.

QUERY_REWRITE_ENABLED allows you to enable or disable query rewriting globally for the database.

Values:

- false
Oracle does not use rewrite.

- true
Oracle costs the query with rewrite and without rewrite and chooses the method with the lower cost.

- force
Oracle always uses rewrite and does not evaluate the cost before doing so. Use force when you know that the query will always benefit from rewrite and when reduction in compile time is important.

To take advantage of query rewrite for a particular materialized view, you must enable query rewrite for that materialized view, and you must enable cost-based optimization.

See Also:

- Oracle Database Data Warehousing Guide for information on query rewrite of materialized views

- Oracle Database Performance Tuning Guide and "OPTIMIZER_MODE" for information on cost-based optimization

QUERY_REWRITE_INTEGRITY

Property

Description

Parameter type

String

Syntax

QUERY_REWRITE_INTEGRITY = { enforced | trusted | stale_tolerated }

Default value

enforced

Modifiable

ALTER SESSION, ALTER SYSTEM

Oracle RAC

Multiple instances can have different values.

QUERY_REWRITE_INTEGRITY determines the degree to which Oracle must enforce query rewriting. At the safest level, Oracle does not use query rewrite transformations that rely on unenforced relationships.

Values:

- enforced
Oracle enforces and guarantees consistency and integrity.

- trusted
Oracle allows rewrites using relationships that have been declared, but that are not enforced by Oracle.

- stale_tolerated
Oracle allows rewrites using unenforced relationships. Materialized views are eligible for rewrite even if they are known to be inconsistent with the underlying detail data.

RDBMS_SERVER_DN

Property

Description

Parameter type

X.500 Distinguished Name

Default value

There is no default value.

Modifiable

No

Range of values

All X.500 Distinguished Name format values

RDBMS_SERVER_DN specifies the Distinguished Name (DN) of the Oracle server. It is used for retrieving Enterprise Roles from an enterprise directory service.

If you do not want to use a directory for enterprise user and privilege management, but prefer to use SSL authentication alone, do not set this parameter.

See Also:

Oracle Database Advanced Security Administrator's Guide for more information on enterprise roles and the enterprise directory service

READ_ONLY_OPEN_DELAYED

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

READ_ONLY_OPEN_DELAYED determines when datafiles in read-only tablespaces are accessed.

Values:

- true
The datafiles are accessed for the first time only when an attempt is made to read data stored within them.

- false
The datafiles are accessed at database open time.

You can use this parameter to speed up some operations (primarily opening the database) for very large databases when substantial portions of the database are stored in read-only tablespaces. Consider setting this parameter to true for such databases, especially if portions of the read-only data are stored on slow-access devices or hierarchical storage.

See Also:

Oracle Database Administrator's Guide for information on the consequences of delaying access of datafiles in read-only tablespaces

RECOVERY_PARALLELISM

Property

Description

Parameter type

Integer

Default value

System-determined parallel recovery

Modifiable

No

Range of values

System-determined, but cannot exceed PARALLEL_MAX_SERVERS initialization parameter setting

RECOVERY_PARALLELISM specifies the number of processes to participate in instance or crash recovery. To force serial crash and instance recovery, set the RECOVERY_PARALLELISM parameter to 0 or 1. 0 or 1 disable parallel instance and crash recovery on a system that has multiple CPUs. An alert log displays the degree of parallelism that was chosen when the database instance/recovery starts.

RECYCLEBIN

Property

Description

Parameter type

String

Syntax

RECYCLEBIN = { on | off }

Default value

on

Modifiable

ALTER SESSION, ALTER SYSTEM ... DEFERRED

Basic

No

RECYCLEBIN is used to control whether the Flashback Drop capability is turned on or off. If the parameter is set to off, then dropped tables do not go into the recycle bin. If this parameter is set to on, then dropped tables go into the recycle bin and can be recovered.

REDO_TRANSPORT_USER

Property

Description

Parameter type

String

Syntax

REDO_TRANSPORT_USER = user_name

Default value

There is no default value.

Range of values

Any character string that matches the name of a user who has been granted the SYSDBA or SYSOPER privilege

Modifiable

ALTER SYSTEM

Basic

No

Oracle RAC

Every instance should use the same value

REDO_TRANSPORT_USER specifies the name of the user whose password verifier is used when a remote login password file is used for redo transport authentication. This user must have the SYSDBA or SYSOPER privilege and must have the same password in the database that initiates the redo transport session and in the database that is the target of the redo transport session.

The value of this parameter is case sensitive and must exactly match the value of the USERNAME column of a row in the V$PWFILE_USERS view. The value of the SYSDBA or SYSOPER column of the row must also be TRUE.

If this parameter is not specified, then the password verifier of the SYS user will be used when a remote login password file is used for redo transport authentication.

REMOTE_DEPENDENCIES_MODE

Property

Description

Parameter type

String

Syntax

REMOTE_DEPENDENCIES_MODE = { TIMESTAMP | SIGNATURE }

Default value

TIMESTAMP

Modifiable

ALTER SESSION, ALTER SYSTEM

REMOTE_DEPENDENCIES_MODE specifies how Oracle should handle dependencies upon remote PL/SQL stored procedures.

Values:

- TIMESTAMP
The client running the procedure compares the timestamp recorded on the server-side procedure with the current timestamp of the local procedure and executes the procedure only if the timestamps match.

- SIGNATURE
Oracle allows the procedure to execute as long as the signatures are considered safe. This setting allows client PL/SQL applications to be run without recompilation.

See Also:

Oracle Database Advanced Application Developer's Guide for information about the consequences of the settings of this parameter

REMOTE_LISTENER

Property

Description

Parameter type

String

Syntax

REMOTE_LISTENER = network_name

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Basic

Yes

REMOTE_LISTENER specifies a network name that resolves to an address or address list of Oracle Net remote listeners (that is, listeners that are not running on the same machine as this instance). The address or address list is specified in the TNSNAMES.ORA file or other address repository as configured for your system.

See Also:

- Oracle Database Concepts for more information about instances, listener processes, and dispatcher processes

- Oracle Database Net Services Administrator's Guide and your operating system-specific Oracle documentation for more information about specifying network addresses for the protocols on your system

REMOTE_LOGIN_PASSWORDFILE

Property

Description

Parameter type

String

Syntax

REMOTE_LOGIN_PASSWORDFILE = { shared | exclusive | none }

Default value

exclusive

Modifiable

No

Basic

Yes

Oracle RAC

Multiple instances must have the same value.

REMOTE_LOGIN_PASSWORDFILE specifies whether Oracle checks for a password file.

Values:

- shared
One or more databases can use the password file. The password file can contain SYS as well as non-SYS users.

- exclusive
The password file can be used by only one database. The password file can contain SYS as well as non-SYS users.

- none
Oracle ignores any password file. Therefore, privileged users must be authenticated by the operating system.

Notes:

- When REMOTE_LOGIN_PASSWORDFILE is set to either exclusive or shared, but the password file does not exist, then the behavior is the same as setting REMOTE_LOGIN_PASSWORDFILE to none.

- If you change REMOTE_LOGIN_PASSWORDFILE to exclusive or shared from none, then ensure that the password file is in sync with the dictionary passwords. See Oracle Database Administrator's Guide for more information.

REMOTE_OS_AUTHENT

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

REMOTE_OS_AUTHENT specifies whether remote clients will be authenticated with the value of the OS_AUTHENT_PREFIX parameter.

RESOURCE_MANAGER_CPU_ALLOCATION

Property

Description

Parameter type

Integer

Default value

The number of logical CPUs reported by the operating system.

Modifiable

ALTER SYSTEM

Range of values

0 to operating system-specific

Basic

No

Note:

The RESOURCE_MANAGER_CPU_ALLOCATION parameter is deprecated. It is retained for backward compatibility only.

RESOURCE_MANAGER_CPU_ALLOCATION specifies the number of CPUs that the Resource Manager should utilize. The Resource Manager controls how a system's CPUs are utilized by its database's sessions.

The Resource Manager schedules database sessions on the CPUs according to a Resource Plan that has been configured and enabled by the DBA. Normally, the Resource Manager schedules enough database sessions to keep all CPUs utilized. However, in some scenarios, a DBA may only want to schedule enough database sessions to keep a subset of the CPUs utilized.

RESOURCE_MANAGER_PLAN

Parameter type

String

Syntax

RESOURCE_MANAGER_PLAN = plan_name

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Range of values

Any valid character string

RESOURCE_MANAGER_PLAN specifies the top-level resource plan to use for an instance. The resource manager will load this top-level plan along with all its descendants (subplans, directives, and consumer groups). If you do not specify this parameter, the resource manager is off by default.

You can change the setting of this parameter using the ALTER SYSTEM statement to turn on the resource manager (if it was previously off) or to turn off the resource manager or change the current plan (if it was previously on). If you specify a plan that does not exist in the data dictionary, Oracle returns an error message.

Syntax

RESULT_CACHE_MAX_SIZE = integer [K | M | G]

Default value

Derived from the values of SHARED_POOL_SIZE, SGA_TARGET, and MEMORY_TARGET

Modifiable

ALTER SYSTEM

Range of values

0 to operating system-dependent

Basic

No

Oracle RAC

You must either set this parameter to 0 on all instances to disable the result cache, or use a nonzero value on all instances. Disabling the result cache on some instances may lead to incorrect results.

RESULT_CACHE_MAX_SIZE specifies the maximum amount of SGA memory (in bytes) that can be used by the Result Cache. Values of this parameter greater than 0 are rounded up to the next multiple of 32 KB. If the value of this parameter is 0, then the feature is disabled.

RESULT_CACHE_MODE

Property

Description

Parameter type

String

Syntax

RESULT_CACHE_MODE = { MANUAL | FORCE }

Default value

MANUAL

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

RESULT_CACHE_MODE specifies when a ResultCache operator is spliced into a query's execution plan.

Values:

- MANUAL
The ResultCache operator is added only when the query is annotated (that is, hints).

- FORCE
The ResultCache operator is added to the root of all SELECT statements (provided that it is valid to do so).

For the FORCE setting, if the statement contains a NO_RESULT_CACHE hint, then the hint takes precedence over the parameter setting.

RESULT_CACHE_REMOTE_EXPIRATION

Property

Description

Parameter type

Integer

Default value

0

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

0 to operating system-dependent

Basic

No

RESULT_CACHE_REMOTE_EXPIRATION specifies the number of minutes that a result using a remote object is allowed to remain valid. Setting this parameter to 0 implies that results using remote objects should not be cached. Setting this parameter to a nonzero value can produce stale answers (for example, if the remote table used by a result is modified at the remote database).

RESUMABLE_TIMEOUT

Property

Description

Parameter type

Integer

Default value

0 (seconds)

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

0 to 2^31 - 1 (in seconds)

Oracle RAC

Multiple instances can have different values.

RESUMABLE_TIMEOUT enables or disables resumable statements and specifies resumable timeout at the system level.

See Also:

Oracle Database Administrator's Guide for more information about enabling resumable space allocation, what conditions are correctable, and what statements can be made resumable

ROLLBACK_SEGMENTS

Property

Description

Parameter type

String

Syntax

ROLLBACK_SEGMENTS =
(segment_name [, segment_name] ... )

Default value

If you do not specify this parameter, the instance uses public rollback segments by default, unless the UNDO_MANAGEMENT initialization parameter is set to AUTO. In that case, the ROLLBACK_SEGMENTS parameter is ignored and automatic undo management is used.

Modifiable

No

Range of values

Any rollback segment names listed in DBA_ROLLBACK_SEGS except SYSTEM

Basic

No

Oracle RAC

Multiple instances must have different values.

ROLLBACK_SEGMENTS allocates one or more rollback segments by name to this instance. If you set this parameter, the instance acquires all of the rollback segments named in this parameter, even if the number of rollback segments exceeds the minimum number required by the instance (calculated as TRANSACTIONS / TRANSACTIONS_PER_ROLLBACK_SEGMENT).

You cannot change the value of this parameter dynamically, but you can change its value and then restart the instance. Although this parameter usually specifies private rollback segments, it can also specify public rollback segments if they are not already in use.

To find the name, segment ID number, and status of each rollback segment in the database, query the data dictionary view DBA_ROLLBACK_SEGS.

When UNDO_MANAGEMENT is set to AUTO, ROLLBACK_SEGMENTS is ignored.

See Also:

- Oracle Database Administrator's Guide for more information on setting this parameter

- Oracle Real Application Clusters Administration and Deployment Guide for information on setting this parameter in an Oracle RAC environment

Property

Description

Parameter type

String

Syntax

SEC_PROTOCOL_ERROR_FURTHER_ACTION = { CONTINUE | (DELAY,integer) | (DROP,integer) }

Default value

CONTINUE

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

SEC_PROTOCOL_ERROR_FURTHER_ACTION specifies the further execution of a server process when receiving bad packets from a possibly malicious client.

Values:

- CONTINUE
The server process continues execution. The database server may be subject to a Denial of Service (DoS) if bad packets continue to be sent by a malicious client.

- (DELAY,integer)
The client experiences a delay of integer seconds before the server process accepts the next request from the same client connection. Malicious clients are prevented from excessive consumption of server resources while legitimate clients experience a degradation in performance but can continue to function.

- (DROP,integer)
The server forcefully terminates the client connection after integer cumulative bad packets. The server protects itself at the expense of the client (for example, a client transaction may be lost). The client may reconnect and attempt the same operation.

SEC_PROTOCOL_ERROR_TRACE_ACTION

Property

Description

Parameter type

String

Syntax

SEC_PROTOCOL_ERROR_TRACE_ACTION = { NONE | TRACE | LOG | ALERT }

Default value

TRACE

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

SEC_RETURN_SERVER_RELEASE_BANNER specifies whether or not the server returns complete database software information to unauthenticated clients.

Values:

- true
Returns complete database version information to the client.

- false
Returns a generic version string to the client.

See Also:

Oracle Call Interface Programmer's Guide and Oracle Database Security Guide for more information on controlling the display of the database version banner.

SERIAL_REUSE

Property

Description

Parameter type

String

Syntax

SERIAL_REUSE = { disable | all | select | dml | plsql | force }

Default value

disable

Modifiable

No

Basic

No

Note:

The SERIAL_REUSE parameter is deprecated. It is retained for backward compatibility only.

SERIAL_REUSE specifies which types of cursors make use of the serial-reusable memory feature. This feature allocates private cursor memory in the SGA so that it can be reused (serially, not concurrently) by sessions executing the same cursor.

Values:

- disable
Disables the option for all SQL statement types. This value overrides any other values included in the list.

- all
Enables the option for both DML and SELECT statements. Equivalent to setting select, dml, and plsql.

- select
Enables the option for SELECT statements.

- dml
Enables the option for DML statements.

- plsql
Currently has no effect (although PLSQL packages do support the serial-reuse memory option using PLSQL pragmas).

Note:

If CURSOR_SPACE_FOR_TIME is set to true, then the value of SERIAL_REUSE is ignored and treated as if it were set to disable.

See Also:

"CURSOR_SPACE_FOR_TIME"

SERVICE_NAMES

Property

Description

Parameter type

String

Syntax

SERVICE_NAMES =
db_service_name [, db_service_name [ ... ] ]

Default value

DB_UNIQUE_NAME.DB_DOMAIN if defined

Modifiable

ALTER SYSTEM

Range of values

Any ASCII string or comma-separated list of string names

Basic

No

Oracle RAC

Do not set the SERVICE_NAMES parameter for Oracle RAC environments. Instead, define services using Oracle Enterprise Manager and manage those services using Server Control (SRVCTL) utility.

SERVICE_NAMES specifies one or more names by which clients can connect to the instance. The instance registers its service names with the listener. When a client requests a service, the listener determines which instances offer the requested service and routes the client to the appropriate instance.

You can specify multiple service names in order to distinguish among different uses of the same database. For example:

SERVICE_NAMES = sales.acme.com, widgetsales.acme.com

You can also use service names to identify a single service that is available from two different databases through the use of replication.

If you do not qualify the names in this parameter with a domain, Oracle qualifies them with the value of the DB_DOMAIN parameter. If DB_DOMAIN is not specified, then no domain will be applied to the non-qualified SERVICE_NAMES values.

SESSION_CACHED_CURSORS

Property

Description

Parameter type

Integer

Default value

50

Modifiable

ALTER SESSION

Range of values

0 to operating system-dependent

Oracle RAC

Multiple instances can have different values.

SESSION_CACHED_CURSORS specifies the number of session cursors to cache. Repeated parse calls of the same SQL (including recursive SQL) or PL/SQL statement cause the session cursor for that statement to be moved into the session cursor cache. Subsequent parse calls will find the cursor in the cache and do not need to reopen the cursor. Oracle uses a least recently used algorithm to remove entries in the session cursor cache to make room for new entries when needed.

See Also:

Oracle Database Performance Tuning Guide for more information on setting this parameter and its uses

SESSION_MAX_OPEN_FILES

Property

Description

Parameter type

Integer

Default value

10

Modifiable

No

Range of values

1 to either 50 or the value of MAX_OPEN_FILES defined at the operating system level, whichever is less

SESSION_MAX_OPEN_FILES specifies the maximum number of BFILEs that can be opened in any session. Once this number is reached, subsequent attempts to open more files in the session by using DBMS_LOB.FILEOPEN() or OCILobFileOpen() will fail. The maximum value for this parameter depends on the equivalent parameter defined for the underlying operating system.

See Also:

- Oracle Database SecureFiles and Large Objects Developer's Guide for information on LOBs in general and BFILEs in particular

- Oracle Database PL/SQL Packages and Types Reference for information on the DBMS_LOB.FILEOPEN() procedure

- Oracle Call Interface Programmer's Guide for information on the OCILobFileOpen() procedure

SESSIONS

Property

Description

Parameter type

Integer

Default value

Derived: (1.5 * PROCESSES) + 22

Modifiable

No

Range of values

1 to 2^31

Basic

Yes

SESSIONS specifies the maximum number of sessions that can be created in the system. Because every login requires a session, this parameter effectively determines the maximum number of concurrent users in the system. You should always set this parameter explicitly to a value equivalent to your estimate of the maximum number of concurrent users, plus the number of background processes, plus approximately 10% for recursive sessions.

Oracle uses the default value of this parameter as its minimum. Values between 1 and the default do not trigger errors, but Oracle ignores them and uses the default instead.

The default values of the ENQUEUE_RESOURCES and TRANSACTIONS parameters are derived from SESSIONS. Therefore, if you increase the value of SESSIONS, you should consider whether to adjust the values of ENQUEUE_RESOURCES and TRANSACTIONS as well. (Note that ENQUEUE_RESOURCES is obsolete as of Oracle Database 10g release 2 (10.2).)

In a shared server environment, the value of PROCESSES can be quite small. Therefore, Oracle recommends that you adjust the value of SESSIONS to approximately 1.1 * total number of connections.

- Oracle Database Concepts for more information on memory structures and processes

SGA_MAX_SIZE

Property

Description

Parameter type

Big integer

Syntax

SGA_MAX_SIZE = integer [K | M | G]

Default value

Initial size of SGA at startup, dependent on the sizes of different pools in the SGA, such as buffer cache, shared pool, large pool, and so on.

Modifiable

No

Range of values

0 to operating system-dependent

SGA_MAX_SIZE specifies the maximum size of the SGA for the lifetime of the instance.

On 64-bit platforms and non-Windows 32-bit platforms, when either MEMORY_TARGET or MEMORY_MAX_TARGET is specified, the default value of SGA_MAX_SIZE is set to the larger of the two parameters. This causes more address space to be reserved for expansion of the SGA.

On Windows 32-bit platforms, the default value of SGA_MAX_SIZE is the largest of the following values:

- 60% of MEMORY_TARGET, if specified

- 60% of MEMORY_MAX_TARGET, if specified

- 25% of the total available virtual address space

SGA_TARGET

Property

Description

Parameter type

Big integer

Syntax

SGA_TARGET = integer [K | M | G]

Default value

0 (SGA autotuning is disabled for DEFERRED mode autotuning requests, but allowed for IMMEDIATE mode autotuning requests)

Modifiable

ALTER SYSTEM

Range of values

64 MB to operating system-dependent

Basic

Yes

SGA_TARGET specifies the total size of all SGA components. If SGA_TARGET is specified, then the following memory pools are automatically sized:

- Buffer cache (DB_CACHE_SIZE)

- Shared pool (SHARED_POOL_SIZE)

- Large pool (LARGE_POOL_SIZE)

- Java pool (JAVA_POOL_SIZE)

- Streams pool (STREAMS_POOL_SIZE)

If these automatically tuned memory pools are set to nonzero values, then those values are used as minimum levels by Automatic Shared Memory Management. You would set minimum values if an application component needs a minimum amount of memory to function properly.

The following pools are manually sized components and are not affected by Automatic Shared Memory Management:

- Log buffer

- Other buffer caches, such as KEEP, RECYCLE, and other block sizes

- Fixed SGA and other internal allocations

The memory allocated to these pools is deducted from the total available for SGA_TARGET when Automatic Shared Memory Management computes the values of the automatically tuned memory pools.

In the Default value field, IMMEDIATE mode autotuning requests are necessary to avoid ORA-04031 errors. The DEFERRED and IMMEDIATE modes are reflected in the OPER_MODE column of the V$MEMORY_RESIZE_OPS view.

See Also:

- Oracle Database Concepts for information on automatic SGA management

- Oracle Database Administrator's Guide for information on managing the SGA

SHADOW_CORE_DUMP

Property

Description

Parameter type

String

Syntax

SHADOW_CORE_DUMP = { partial | full | none }

Default value

partial

Modifiable

No

SHADOW_CORE_DUMP specifies whether Oracle includes the SGA in the core file for foreground (client) processes.

Values:

- partial
Oracle does not include the SGA in the core dump.

- full
Oracle includes the SGA in the core dump.

- none
No core files will be generated for foreground processes.

See Also:

"BACKGROUND_CORE_DUMP"

SHARED_MEMORY_ADDRESS

Property

Description

Parameter type

Integer

Default value

0

Modifiable

No

SHARED_MEMORY_ADDRESS and HI_SHARED_MEMORY_ADDRESS specify the starting address at runtime of the system global area (SGA). This parameter is ignored on the many platforms that specify the SGA's starting address at linktime.

Use this parameter to specify the entire address on 32-bit platforms and to specify the low-order 32 bits of a 64-bit address on 64-bit platforms. Use HI_SHARED_MEMORY_ADDRESS to specify the high-order 32 bits of a 64-bit address on 64-bit platforms. If both parameters are 0 or unspecified, the SGA address defaults to a platform-specific location.

See Also:

"HI_SHARED_MEMORY_ADDRESS"

SHARED_POOL_RESERVED_SIZE

Property

Description

Parameter type

Big integer

Syntax

SHARED_POOL_RESERVED_SIZE = integer [K | M | G]

Default value

5% of the value of SHARED_POOL_SIZE

Modifiable

No

Range of values

Minimum: 5000
Maximum: one half of the value of SHARED_POOL_SIZE

SHARED_POOL_RESERVED_SIZE specifies (in bytes) the shared pool space that is reserved for large contiguous requests for shared pool memory.

You can use this parameter to avoid performance degradation in the shared pool in situations where pool fragmentation forces Oracle to search for and free chunks of unused pool to satisfy the current request.

See Also:

- Oracle Database Performance Tuning Guide for more information on setting this parameter

- "SHARED_POOL_SIZE"

SHARED_POOL_SIZE

Property

Description

Parameter type

Big integer

Syntax

SHARED_POOL_SIZE = integer [K | M | G]

Default value

If SGA_TARGET is set: If the parameter is not specified, then the default is 0 (internally determined by the Oracle Database). If the parameter is specified, then the user-specified value indicates a minimum value for the memory pool.
If SGA_TARGET is not set (32-bit platforms): 64 MB, rounded up to the nearest granule size.

If SGA_TARGET is not set (64-bit platforms): 128 MB, rounded up to the nearest granule size.

For considerations when dealing with database instances using ASM, see "SHARED_POOL_SIZE and Automatic Storage Management".

Modifiable

ALTER SYSTEM

Range of values

Minimum: the granule size
Maximum: operating system-dependent

SHARED_POOL_SIZE specifies (in bytes) the size of the shared pool. The shared pool contains shared cursors, stored procedures, control structures, and other structures. If you set PARALLEL_AUTOMATIC_TUNING to false, then Oracle also allocates parallel execution message buffers from the shared pool. Larger values improve performance in multi-user systems. Smaller values use less memory.

You can monitor utilization of the shared pool by querying the view V$SGASTAT.

See Also:

- Oracle Database Performance Tuning Guide for more information on setting this parameter

- Oracle Database Upgrade Guide for information on parallel execution message buffers

- "PARALLEL_AUTOMATIC_TUNING" and "V$SGASTAT"

SHARED_POOL_SIZE and Automatic Storage Management

On a database instance using ASM, additional memory is required to store extent maps. As a general guideline, you can aggregate the values from the following queries to obtain current database storage size that is either already on ASM or will be stored in ASM. Then determine the redundancy type that is used (or will be used), and calculate the value for SHARED_POOL_SIZE, using the aggregated value as input.

SELECT SUM(BYTES)/(1024*1024*1024) FROM V$DATAFILE;
SELECT SUM(BYTES)/(1024*1024*1024) FROM V$LOGFILE a, V$LOG b
WHERE a.group#=b.group#;
SELECT SUM(BYTES)/(1024*1024*1024) FROM V$TEMPFILE WHERE
status='ONLINE';

Additionally, keep the following guidelines in mind:

- For diskgroups using external redundancy:
(Every 100G of space needs 1M of extra shared pool) + 2M

- For diskgroups using normal redundancy:
(Every 50G of space needs 1M of extra shared pool) + 4M

- For diskgroups using high redundancy:
(Every 33G of space needs 1M of extra shared pool) + 6M

SHARED_SERVER_SESSIONS

Property

Description

Parameter type

Integer

Default value

There is no default value.

Modifiable

ALTER SYSTEM

Range of values

If SHARED_SERVER_SESSIONS is specified, then it should be less than SESSIONS. If SHARED_SERVER_SESSIONS is not specified, then a shared server session may be created as long as there is a free session slot.

SHARED_SERVER_SESSIONS specifies the total number of shared server sessions to allow. Setting this parameter enables you to reserve user sessions for dedicated servers.

See Also:

Oracle Database Concepts for more information on sessions

SHARED_SERVERS

Property

Description

Parameter type

Integer

Default value

0, meaning that shared server is not on.
If you are using shared server architecture or if the DISPATCHERS parameter is set such that the total number of dispatchers is more than 0, then the default value is 1.

Modifiable

ALTER SYSTEM

Range of values

The value of this parameter should be less than MAX_SHARED_SERVERS. If it is greater than or equal to MAX_SHARED_SERVERS, then the number of servers will not be self-tuned but will remain constant, as specified by SHARED_SERVERS.

Basic

Yes

SHARED_SERVERS specifies the number of server processes that you want to create when an instance is started. If system load decreases, then this minimum number of servers is maintained. Therefore, you should take care not to set SHARED_SERVERS too high at system startup.

See Also:

Oracle Database Administrator's Guide for more information on setting this parameter

SKIP_UNUSABLE_INDEXES

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

SKIP_UNUSABLE_INDEXES enables or disables the use and reporting of tables with unusable indexes or index partitions. If a SQL statement uses a hint that forces the usage of an unusable index, then this hint takes precedence over initialization parameter settings, including SKIP_UNUSABLE_INDEXES. If the optimizer chooses an unusable index, then an ORA-01502 error will result. (See Oracle Database Administrator's Guide for more information about using hints.)

Values:

- true
Disables error reporting of indexes and index partitions marked UNUSABLE. This setting allows all operations (inserts, deletes, updates, and selects) on tables with unusable indexes or index partitions.

Note:

If an index is used to enforce a UNIQUE constraint on a table, then allowing insert and update operations on the table might violate the constraint. Therefore, this setting does not disable error reporting for unusable indexes that are unique.

- false
Enables error reporting of indexes marked UNUSABLE. This setting does not allow inserts, deletes, and updates on tables with unusable indexes or index partitions.

SMTP_OUT_SERVER

Property

Description

Parameter type

String

Syntax

SMTP_OUT_SERVER = server_clause [, server_clause ] ...

server_clause::=
host_name[:port]

Default value

There is no default value.

Modifiable

ALTER SESSION, ALTER SYSTEM

SMTP_OUT_SERVER specifies the SMTP host and port to which UTL_MAIL delivers out-bound E-mail. Multiple servers may be specified, separated by commas.

If the first server in the list is unavailable, then UTL_MAIL tries the second server, and so on.

If SMTP_OUT_SERVER is not specified, then the SMTP server name defaults to the value of DB_DOMAIN, the port number defaults to 25, and the SMTP domain defaults to the suffix of DB_DOMAIN.

See Also:

Oracle Database PL/SQL Packages and Types Reference for information on the UTL_MAIL package

SORT_AREA_RETAINED_SIZE

Property

Description

Parameter type

Integer

Default value

Derived from SORT_AREA_SIZE

Modifiable

ALTER SESSION, ALTER SYSTEM ... DEFERRED

Range of values

From the value equivalent of two database blocks to the value of SORT_AREA_SIZE

Note:

Oracle does not recommend using the SORT_AREA_RETAINED_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_RETAINED_SIZE is retained for backward compatibility.

SORT_AREA_RETAINED_SIZE specifies (in bytes) the maximum amount of the user global area (UGA) memory retained after a sort run completes. The retained size controls the size of the read buffer, which Oracle uses to maintain a portion of the sort in memory. This memory is released back to the UGA, not to the operating system, after the last row is fetched from the sort space.

Oracle may allocate multiple sort spaces of this size for each query. Usually, only one or two sorts occur at one time, even for complex queries. In some cases, however, additional concurrent sorts are required, and each sort keeps its own memory area. If the shared server is used, allocation is to the SGA until the value in SORT_AREA_RETAINED_SIZE is reached. The difference between SORT_AREA_RETAINED_SIZE and SORT_AREA_SIZE is allocated to the PGA.

Note:

The default value as reflected in the V$PARAMETER dynamic performance view is 0. However, if you do not explicitly set this parameter, Oracle actually uses the value of the SORT_AREA_SIZE parameter.

See Also:

- Oracle Database Performance Tuning Guide for more information on setting this parameter

- "SORT_AREA_SIZE"

SORT_AREA_SIZE

Property

Description

Parameter type

Integer

Default value

65536

Modifiable

ALTER SESSION, ALTER SYSTEM ... DEFERRED

Range of values

Minimum: the value equivalent of six database blocks
Maximum: operating system-dependent

Note:

Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_SIZE is retained for backward compatibility.

SORT_AREA_SIZE specifies (in bytes) the maximum amount of memory Oracle will use for a sort. After the sort is complete, but before the rows are returned, Oracle releases all of the memory allocated for the sort, except the amount specified by the SORT_AREA_RETAINED_SIZE parameter. After the last row is returned, Oracle releases the remainder of the memory.

Increasing SORT_AREA_SIZE size improves the efficiency of large sorts.

Each sort in a query can consume memory up to the amount specified by SORT_AREA_SIZE, and there can be multiple sorts in a query. Also, if a query is executed in parallel, each PQ slave can consume memory up to the amount specified by SORT_AREA_SIZE for each sort it does.

SORT_AREA_SIZE is also used for inserts and updates to bitmap indexes. Setting this value appropriately results in a bitmap segment being updated only once for each DML operation, even if more than one row in that segment changes.

Larger values of SORT_AREA_SIZE permit more sorts to be performed in memory. If more space is required to complete the sort than will fit into the memory provided, then temporary segments on disk are used to hold the intermediate sort runs.

The default is adequate for most OLTP operations. You might want to adjust this parameter for decision support systems, batch jobs, or large CREATE INDEX operations.

See Also:

- Oracle Database Performance Tuning Guide for more information on setting this parameter

- Oracle Database Concepts for information on logical storage structures such as sort areas

SPFILE

Property

Description

Parameter type

String

Syntax

SPFILE = spfile_name

Default value

ORACLE_HOME/dbs/spfile.ora

Modifiable

No

Range of values

Any valid SPFILE

Oracle RAC

Multiple instances should have the same value.

The value of this parameter is the name of the current server parameter file (SPFILE) in use. This parameter can be defined in a client side PFILE to indicate the name of the server parameter file to use.

When the default server parameter file is used by the server, the value of SPFILE is internally set by the server.

The SPFILE resides in the ORACLE_HOME/dbs directory; however, users can place it anywhere on their machine as long as it is specified in an initialization parameter file.

See Also:

Oracle Database Administrator's Guide for more information about creating the server parameter file

SQL_TRACE

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

SQL_TRACE enables or disables the SQL trace facility. Setting this parameter to true provides information on tuning that you can use to improve performance.

Caution:

Using this initialization parameter to enable the SQL trace facility for the entire instance can have a severe performance impact. Enable the facility for specific sessions using the ALTER SESSION statement. If you must enable the facility on an entire production environment, then you can minimize performance impact by:

- Maintaining at least 25% idle CPU capacity

- Maintaining adequate disk space for the USER_DUMP_DEST location

- Striping disk space over sufficient disks

See Also:

Oracle Database Performance Tuning Guide for more information about performance diagnostic tools

Note:

The SQL_TRACE parameter is deprecated. Oracle recommends that you use the DBMS_MONITOR and DBMS_SESSION packages instead. SQL_TRACE is retained for backward compatibility only.

SQL92_SECURITY

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

The SQL standard specifies that security administrators should be able to require that users have SELECT privilege on a table when executing an UPDATE or DELETE statement that references table column values in a WHERE or SET clause. SQL92_SECURITY specifies whether users must have been granted the SELECT object privilege in order to execute such UPDATE or DELETE statements.

Values:

- true
The user must have SELECT privilege on a column in order to reference it in the WHERE clause of a DELETE or UPDATE statement, on the right hand side of an assignment in the SET clause of an UPDATE statement.

- false
A user with DELETE privilege on the target table of a DELETE statement may reference any column of that target table in the WHERE clause. A user with UPDATE privilege on the target table of an UPDATE statement may reference any column of that target in the WHERE clause or on the right hand side of any assignment in the SET clause of the UPDATE statement.

SQLTUNE_CATEGORY

Property

Description

Parameter type

String

Syntax

SQLTUNE_CATEGORY = category_name

Default value

DEFAULT

Modifiable

ALTER SESSION, ALTER SYSTEM

SQLTUNE_CATEGORY specifies the category name for use by sessions to qualify the lookup of SQL profiles during SQL compilation.

See Also:

Oracle Database PL/SQL Packages and Types Reference for information on the DBMS_SQLTUNE package

STANDBY_ARCHIVE_DEST

Property

Description

Parameter type

String

Syntax

STANDBY_ARCHIVE_DEST = filespec

Default value

Operating system-specific

Modifiable

ALTER SYSTEM

Range of values

A valid path or device name other than RAW

Note:

The STANDBY_ARCHIVE_DEST parameter is deprecated. It is retained for backward compatibility only.

STANDBY_ARCHIVE_DEST can be used to specify where archived logs received from a primary database are stored on a standby database. It is no longer necessary to set this parameter, because an appropriate location is automatically chosen.

See Also:

Oracle Data Guard Concepts and Administration for more information

STANDBY_FILE_MANAGEMENT

Property

Description

Parameter type

String

Syntax

STANDBY_FILE_MANAGEMENT = { MANUAL | AUTO }

Default value

MANUAL

Modifiable

ALTER SYSTEM

STANDBY_FILE_MANAGEMENT enables or disables automatic standby file management. When automatic standby file management is enabled, operating system file additions and deletions on the primary database are replicated on the standby database. STANDBY_FILE_MANAGEMENT is only applicable to physical standby databases.

Values:

- MANUAL
disables automatic standby file management

- AUTO
enables automatic standby file management

Setting STANDBY_FILE_MANAGEMENT to AUTO causes Oracle to automatically create files on the standby database and, in some cases, overwrite existing files. Care must be taken when setting STANDBY_FILE_MANAGEMENT and DB_FILE_NAME_CONVERT so that existing standby files will not be accidentally overwritten.

If the standby database is on the same system as the primary database, then ensure that the primary and standby systems do not point to the same files.

See Also:

Oracle Data Guard Concepts and Administration for more information about setting this parameter

STAR_TRANSFORMATION_ENABLED

Property

Description

Parameter type

String

Syntax

STAR_TRANSFORMATION_ENABLED = { FALSE | TRUE | TEMP_DISABLE }

Default value

FALSE

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

Yes

STAR_TRANSFORMATION_ENABLED determines whether a cost-based query transformation will be applied to star queries.

Values:

- FALSE
The transformation will not be applied.

- TRUE
The optimizer will consider performing a cost-based query transformation on the star query.

- TEMP_DISABLE
The optimizer will consider performing a cost-based query transformation on the star query but will not use temporary tables in the star transformation.

See Also:

- Oracle Database Concepts for information on star queries

- Oracle Database Performance Tuning Guide for information on enabling star query

STATISTICS_LEVEL

Property

Description

Parameter type

String

Syntax

STATISTICS_LEVEL = { ALL | TYPICAL | BASIC }

Default value

TYPICAL

Modifiable

ALTER SESSION, ALTER SYSTEM

STATISTICS_LEVEL specifies the level of collection for database and operating system statistics. The Oracle Database collects these statistics for a variety of purposes, including making self-management decisions.

The default setting of TYPICAL ensures collection of all major statistics required for database self-management functionality and provides best overall performance. The default value should be adequate for most environments.

When the STATISTICS_LEVEL parameter is set to ALL, additional statistics are added to the set of statistics collected with the TYPICAL setting. The additional statistics are timed OS statistics and plan execution statistics.

Setting the STATISTICS_LEVEL parameter to BASIC disables the collection of many of the important statistics required by Oracle Database features and functionality, including:

- Automatic Workload Repository (AWR) Snapshots

- Automatic Database Diagnostic Monitor (ADDM)

- All server-generated alerts

- Automatic SGA Memory Management

- Automatic optimizer statistics collection

- Object level statistics

- End to End Application Tracing (V$CLIENT_STATS)

- Database time distribution statistics (V$SESS_TIME_MODEL and V$SYS_TIME_MODEL)

- Service level statistics

- Buffer cache advisory

- MTTR advisory

- Shared pool sizing advisory

- Segment level statistics

- PGA Target advisory

- Timed statistics

- Monitoring of statistics

Note:

Oracle strongly recommends that you do not disable these important features and functionality.

When the STATISTICS_LEVEL parameter is modified by ALTER SYSTEM, all advisories or statistics are dynamically turned on or off, depending on the new value of STATISTICS_LEVEL. When modified by ALTER SESSION, the following advisories or statistics are turned on or off in the local session only. Their system-wide state is not changed:

- Timed statistics

- Timed OS statistics

- Plan execution statistics

The V$STATISTICS_LEVEL view displays information about the status of the statistics or advisories controlled by the STATISTICS_LEVEL parameter. See "V$STATISTICS_LEVEL".

STREAMS_POOL_SIZE

Property

Description

Parameter type

Big integer

Syntax

STREAMS_POOL_SIZE = integer [K | M | G]

Default value

0

Modifiable

ALTER SYSTEM

Range of values

Minimum: 0 (values greater than zero are rounded up to the nearest granule size)
Maximum: operating system-dependent

Oracle's Automatic Shared Memory Management feature manages the size of the Streams pool when the SGA_TARGET initialization parameter is set to a nonzero value. If the STREAMS_POOL_SIZE initialization parameter also is set to a nonzero value, then Automatic Shared Memory Management uses this value as a minimum for the Streams pool.

If the STREAMS_POOL_SIZE initialization parameter is set to a nonzero value, and the SGA_TARGET parameter is set to 0 (zero), then the Streams pool size is the value specified by the STREAMS_POOL_SIZE parameter, in bytes.

If both the STREAMS_POOL_SIZE and the SGA_TARGET initialization parameters are set to 0 (zero), then, by default, the first use of Streams in a database transfers an amount of memory equal to 10% of the shared pool from the buffer cache to the Streams pool.

See Also:

Oracle Streams Replication Administrator's Guide

TAPE_ASYNCH_IO

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

No

Range of values

true | false

TAPE_ASYNCH_IO controls whether I/O to sequential devices (for example, backup or restore of Oracle data to or from tape) is asynchronous—that is, whether parallel server processes can overlap I/O requests with CPU processing during table scans. If your platform supports asynchronous I/O to sequential devices, Oracle recommends that you leave this parameter set to its default. However, if the asynchronous I/O implementation is not stable, you can set TAPE_ASYNCH_IO to false to disable asynchronous I/O. If your platform does not support asynchronous I/O to sequential devices, this parameter has no effect.

See Also:

Oracle Database Performance Tuning Guide for more information on asynchronous I/O and on setting this parameter

THREAD

Property

Description

Parameter type

Integer

Default value

0

Modifiable

No

Range of values

0 to the maximum number of enabled threads

Oracle RAC

If specified, multiple instances must have different values.

THREAD has been superseded by the INSTANCE_NAME and INSTANCE_NUMBER parameters, and will be made obsolete in a future release of the Oracle Database.

See Also:

"INSTANCE_NAME" and "INSTANCE_NUMBER"

TIMED_OS_STATISTICS

Property

Description

Parameter type

Integer

Default value

If STATISTICS_LEVEL is set to ALL, then 5
If STATISTICS_LEVEL is set to BASIC or TYPICAL, then 0

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

Unlimited

TIMED_OS_STATISTICS specifies (in seconds) the interval at which Oracle collects operating system statistics when a request is made from the client to the server or when a request completes.

- On dedicated servers, Oracle collects operating system statistics at user logon and after each subsequent client invocation through the OCI into the Oracle server as a remote procedure call message.

- On shared servers, Oracle collects statistics when client calls to Oracle are processed.

A value of zero specifies that operating system statistics are not gathered. To collect statistics, set a value meaningful for your application and site needs.

Note:

Gathering operating system statistics is very expensive. Oracle recommends that you set this parameter in an ALTER SYSTEM statement rather than in the initialization parameter file, and that you reset the value to zero as soon as the needed statistics have been gathered.

TIMED_STATISTICS

Property

Description

Parameter type

Boolean

Default value

If STATISTICS_LEVEL is set to TYPICAL or ALL, then true
If STATISTICS_LEVEL is set to BASIC, then false

Modifiable

ALTER SESSION, ALTER SYSTEM

Range of values

true | false

TIMED_STATISTICS specifies whether or not statistics related to time are collected.

Values:

- true
The statistics are collected and stored in trace files or displayed in the V$SESSTATS and V$SYSSTATS dynamic performance views.

- false
The value of all time-related statistics is set to zero. This setting lets Oracle avoid the overhead of requesting the time from the operating system.

Starting with release 11.1.0.7.0, the value of the TIMED_STATISTICS parameter cannot be set to false if the value of STATISTICS_LEVEL is set to TYPICAL or ALL.

On some systems with very fast timer access, Oracle might enable timing even if this parameter is set to false. On these systems, setting the parameter to true can sometimes produce more accurate statistics for long-running operations.

See Also:

- Oracle Database Performance Tuning Guide for more information on setting this parameter and on performance diagnostic tools in general

- Appendix E, "Statistics Descriptions" indicates which statistics depend on the setting of this parameter.

TRACE_ENABLED

Property

Description

Parameter type

Boolean

Default value

true

Modifiable

ALTER SYSTEM

Range of values

true | false

Oracle RAC

The default value is TRUE. Oracle recommends that multiple instances have the same value.

TRACE_ENABLED controls tracing of the execution history, or code path, of Oracle. Oracle Support Services uses this information for debugging.

When TRACE_ENABLED is set to true, Oracle records information in specific files when errors occur.

Oracle records this information for all instances, even if only one instance terminates. This allows Oracle to retain diagnostics for an entire cluster.

Although the overhead incurred from this processing is not excessive, you can improve performance by setting TRACE_ENABLED to false. You might do this, for example, to meet high-end benchmark requirements. However, if you leave this parameter set to false, you may lose valuable diagnostic information. Therefore, always set TRACE_ENABLED to true to trace system problems and to reduce diagnostic efforts in the event of unexplained instance failures.

TRACEFILE_IDENTIFIER

Property

Description

Parameter type

String

Syntax

TRACEFILE_IDENTIFIER = "traceid"

Default value

There is no default value.

Modifiable

ALTER SESSION

Range of values

Any characters that can occur as part of a file name on the customer platform

TRACEFILE_IDENTIFIER specifies a custom identifier that becomes part of the Oracle Trace file name. Such a custom identifier is used to identify a trace file simply from its name and without having to open it or view its contents.

Each time this parameter is dynamically modified, the next trace dump will be written to a trace file which has the new parameter value embedded in its name. Trace file continuity information is automatically added to both the old and new trace files to indicate that these trace files belong to the same process.

This parameter can only be used to change the name of the foreground process' trace file; the background processes continue to have their trace files named in the regular format. For foreground processes, the TRACEID column of the V$PROCESS view contains the current value of the TRACEFILE_IDENTIFIER parameter. When this parameter value is set, the trace file name has the following format:

sid_ora_pid_traceid.trc

In this example, sid is the Oracle instance ID, pid is the process ID, and traceid is the value of the TRACEFILE_IDENTIFIER parameter.

See Also:

This parameter is not supported on all operating systems. See your operating system-specific Oracle documentation for more information.

TRANSACTIONS

Property

Description

Parameter type

Integer

Default value

Derived: (1.1 * SESSIONS)

Modifiable

No

Range of values

4 to 2^32

Oracle RAC

Multiple instances can have different values.

TRANSACTIONS specifies how many rollback segments to online when UNDO_MANAGEMENT = MANUAL. The maximum number of concurrent transactions is now restricted by undo tablespace size (UNDO_MANAGEMENT = AUTO) or the number of online rollback segments (UNDO_MANAGEMENT = MANUAL).

See Also:

- Oracle Database Administrator's Guide for information on setting this parameter

- Oracle Real Application Clusters Administration and Deployment Guide for the relationship of this parameter to the number of rollback segments

TRANSACTIONS_PER_ROLLBACK_SEGMENT

Property

Description

Parameter type

Integer

Default value

5

Modifiable

No

Range of values

1 to operating system-dependent

Oracle RAC

Multiple instances can have different values.

TRANSACTIONS_PER_ROLLBACK_SEGMENT specifies the number of concurrent transactions you expect each rollback segment to have to handle. The minimum number of rollback segments acquired at startup is TRANSACTIONS divided by the value for this parameter. For example, if TRANSACTIONS is 101 and this parameter is 10, then the minimum number of rollback segments acquired would be the ratio 101/10, rounded up to 11.

You can acquire more rollback segments by naming them in the parameter ROLLBACK_SEGMENTS.

See Also:

- Oracle Database Administrator's Guide for information on setting this parameter.

- Oracle Real Application Clusters Administration and Deployment Guide for how Oracle acquires rollback segments.

- Your operating system-specific Oracle documentation for the range of values for this parameter.

UNDO_MANAGEMENT

Property

Description

Parameter type

String

Syntax

UNDO_MANAGEMENT = { MANUAL | AUTO }

Default value

AUTO

Modifiable

No

Basic

No

Oracle RAC

Multiple instances must have the same value.

UNDO_MANAGEMENT specifies which undo space management mode the system should use. When set to AUTO, the instance starts in automatic undo management mode. In manual undo management mode, undo space is allocated externally as rollback segments.

UNDO_RETENTION

Property

Description

Parameter type

Integer

Default value

900

Modifiable

ALTER SYSTEM

Range of values

0 to 2^31 - 1

Oracle RAC

Oracle recommends that multiple instances have the same value.

UNDO_RETENTION specifies (in seconds) the low threshold value of undo retention. For AUTOEXTEND undo tablespaces, the system retains undo for at least the time specified in this parameter, and automatically tunes the undo retention period to satisfy the undo requirements of the queries. For fixed- size undo tablespaces, the system automatically tunes for the maximum possible undo retention period, based on undo tablespace size and usage history, and ignores UNDO_RETENTION unless retention guarantee is enabled.

The setting of this parameter should account for any flashback requirements of the system. Automatic tuning of undo retention is not supported for LOBs. The RETENTION value for LOB columns is set to the value of the UNDO_RETENTION parameter.

The UNDO_RETENTION parameter can only be honored if the current undo tablespace has enough space. If an active transaction requires undo space and the undo tablespace does not have available space, then the system starts reusing unexpired undo space. This action can potentially cause some queries to fail with a "snapshot too old" message.

The amount of time for which undo is retained for the Oracle Database for the current undo tablespace can be obtained by querying the TUNED_UNDORETENTION column of the V$UNDOSTAT dynamic performance view.

See Also:

- Oracle Database SQL Language Reference for more information about creating undo tablespaces

- Oracle Database Administrator's Guide for more information about managing undo data

UNDO_TABLESPACE

Property

Description

Parameter type

String

Syntax

UNDO_TABLESPACE = undoname

Default value

The first available undo tablespace in the database.

Modifiable

ALTER SYSTEM

Range of values

Legal name of an existing undo tablespace

Basic

Yes

Oracle RAC

Each instance must have a unique value for this parameter, when it is set.

UNDO_TABLESPACE specifies the undo tablespace to be used when an instance starts up. If this parameter is specified when the instance is in manual undo management mode, then an error will occur and startup will fail.

If the UNDO_TABLESPACE parameter is omitted, the first available undo tablespace in the database is chosen. If no undo tablespace is available, the instance will start without an undo tablespace. In such cases, user transactions will be executed using the SYSTEM rollback segment. You should avoid running in this mode under normal circumstances.

You can replace an undo tablespace with another undo tablespace while the instance is running.

See Also:

Oracle Database SQL Language Reference.

USE_INDIRECT_DATA_BUFFERS

Property

Description

Parameter type

Boolean

Default value

false

Modifiable

No

Range of values

true | false

USE_INDIRECT_DATA_BUFFERS controls how the system global area (SGA) uses memory. It enables or disables the use of the extended buffer cache mechanism for 32-bit platforms that can support more than 4 GB of physical memory. On platforms that do not support this much physical memory, this parameter is ignored.

See Also:

- "LOCK_SGA", "SHARED_MEMORY_ADDRESS", and "HI_SHARED_MEMORY_ADDRESS", which are other parameters that control how the SGA uses memory.

- Oracle Database Concepts for more information about the SGA.

USER_DUMP_DEST

Property

Description

Parameter type

String

Syntax

USER_DUMP_DEST = { pathname | directory }

Default value

Operating system-dependent

Modifiable

ALTER SYSTEM

Range of values

Any valid local path, directory, or disk

USER_DUMP_DEST specifies the pathname for a directory where the server will write debugging trace files on behalf of a user process.

For example, this directory might be set as follows:

- On MS-DOS: C:\ORACLE\UTRC

- On UNIX: /oracle/utrc

- On VMS: DISK$UR3:[ORACLE.UTRC]

Note:

This parameter is ignored by the new diagnosability infrastructure introduced in Oracle Database 11g Release 1, which places trace and core files in a location controlled by the DIAGNOSTIC_DEST initialization parameter.

See Also:

- Oracle Database Performance Tuning Guide for more information about the use of trace files

- Your operating system-specific Oracle documentation for the range of values

UTL_FILE_DIR

Property

Description

Parameter type

String

Syntax

UTL_FILE_DIR = pathname

Default value

There is no default value.

Modifiable

No

Range of values

Any valid directory path

UTL_FILE_DIR lets you specify one or more directories that Oracle should use for PL/SQL file I/O. If you are specifying multiple directories, you must repeat the UTL_FILE_DIR parameter for each directory on separate lines of the initialization parameter file.

All users can read or write to all files specified by this parameter. Therefore all PL/SQL users must be trusted with the information in the directories specified by this parameter.

Note:

If you list multiple values, all entries of this parameter must be on contiguous lines of the parameter file. If you separate them with other parameters, Oracle will read only the last (contiguous) lines.

WORKAREA_SIZE_POLICY

Property

Description

Parameter type

String

Syntax

WORKAREA_SIZE_POLICY = { AUTO | MANUAL }

Default value

AUTO

Modifiable

ALTER SESSION, ALTER SYSTEM

WORKAREA_SIZE_POLICY specifies the policy for sizing work areas. This parameter controls the mode in which working areas are tuned.

Values:

- AUTO
Work areas used by memory-intensive operators are sized automatically, based on the PGA memory used by the system, the target PGA memory set in PGA_AGGREGATE_TARGET, and the requirement of each individual operator.

- MANUAL
The sizing of work areas is manual and based on the values of the *_AREA_SIZE parameter corresponding to the operation (for example, a sort uses SORT_AREA_SIZE). Specifying MANUAL may result in sub-optimal performance and poor PGA memory utilization.

XML_DB_EVENTS

Property

Description

Parameter type

String

Syntax

XML_DB_EVENTS = { enable | disable }

Default value

enable

Modifiable

ALTER SESSION, ALTER SYSTEM

Basic

No

XML_DB_EVENTS enables or disables XML DB Events.

Changing this parameter through an ALTER SESSION statement affects only the current session. Only users with the XDBADMIN role are allowed to change this parameter in a session.

Changing this parameter through an ALTER SYSTEM statement will make a system-wide change of this parameter; however, the change is only registered by new sessions started after the change. Currently running sessions need to be restarted to pick up the new change. Users must have the ALTER SYSTEM privilege to make a system-wide change.

Part II

Static Data Dictionary Views

This part describes data dictionary tables and views. These tables and views are called static, because they change only when a change is made to the data dictionary (for example, when a new table is created or when a user is granted new privileges). This part contains the following chapters:

- Chapter 2, "Static Data Dictionary Views: ALL_ALL_TABLES to ALL_OUTLINES"

- Chapter 3, "Static Data Dictionary Views: ALL_PART_COL_STATISTICS to DATABASE_PROPERTIES"

- Chapter 4, "Static Data Dictionary Views: DBA_2PC_NEIGHBORS to DBA_HIST_JAVA_POOL_ADVICE"

- Chapter 5, "Static Data Dictionary Views: DBA_HIST_LATCH to DBA_STORED_SETTINGS"

- Chapter 6, "Static Data Dictionary Views: DBA_STREAMS_ADD_COLUMN to XS_SESSION_ROLES"

Note:

Oracle also maintains tables that monitor ongoing database activity. These dynamic performance tables are described in Part III, "Dynamic Performance Views".

2 Static Data Dictionary Views: ALL_ALL_TABLES to ALL_OUTLINES

This chapter describes the first set (in alphabetical order) of static data dictionary views.The remaining static data dictionary views appear in alphabetical order in Chapter 3 through Chapter 6.

This chapter contains the following topics:

- About Static Data Dictionary Views

- Static Data Dictionary View Descriptions

About Static Data Dictionary Views

Data dictionary tables are not directly accessible, but you can access information in them through data dictionary views. To list the data dictionary views available to you, query the view DICTIONARY.

Many data dictionary tables have three corresponding views:

- An ALL_ view displays all the information accessible to the current user, including information from the current user's schema as well as information from objects in other schemas, if the current user has access to those objects by way of grants of privileges or roles.

- A DBA_ view displays all relevant information in the entire database. DBA_ views are intended only for administrators. They can be accessed only by users with the SELECT ANY TABLE privilege. This privilege is assigned to the DBA role when the system is initially installed.

- A USER_ view displays all the information from the schema of the current user. No special privileges are required to query these views.

The columns of the ALL_, DBA_, and USER_ views corresponding to a single data dictionary table are usually nearly identical. Therefore, these views are described in full only once in this chapter, at their first occurrence alphabetically, and are listed without full descriptions at their other occurrences.

A number of data dictionary views are relevant only if you are using Oracle Replication. Table 2-1 lists these views.

ARGUMENT_NAME

VARCHAR2(30)

If the argument is a scalar type, then the argument name is the name of the argument. A null argument name is used to denote a function return. If the function return or argument is a composite type, this view will have one row for each attribute of the composite type. Attributes are recursively expanded if they are composite.
The meanings of ARGUMENT_NAME, POSITION, SEQUENCE, and DATA_LEVEL are interdependent. Together, as a tuple, they represent a node of a flattened tree.

ARGUMENT_NAME can refer to any of the following:

- Return type, if ARGUMENT_NAME is null and DATA_LEVEL = 0

- The argument that appears in the argument list if ARGUMENT_NAME is not null and DATA_LEVEL = 0

- Attribute name of the composite type if ARGUMENT_NAME is not null and DATA_LEVEL > 0;

- A collection element type if ARGUMENT_NAME is null and DATA_LEVEL > 0;

POSITION

NUMBER

NOT NULL

If DATA_LEVEL is zero, then this column holds the position of this item in the argument list, or zero for a function return value.If DATA_LEVEL is greater than zero, then this column holds the position of this item with respect to its siblings at the same DATA_LEVEL. So, for a referenced record field, this is the index of the field within the record. For a referenced collection element, this is 1 (because collection elements do not have siblings.)

SEQUENCE

NUMBER

NOT NULL

Defines the sequential order of the argument and its attributes. Argument sequence starts from 1. Return type and its recursively expanded (preorder tree walk) attributes will come first, and each argument with its recursively expanded (preorder tree walk) attributes will follow.

DATA_LEVEL

NUMBER

NOT NULL

VARCHAR2(19)

Relationship between the contents of the materialized view and the contents of the materialized view's masters:

- FRESH - Materialized view is a read-consistent view of the current state of its masters

- STALE - Materialized view is out of date because one or more of its masters has changed. If the materialized view was FRESH before it became STALE, then it is a read-consistent view of a former state of its masters.

- UNUSABLE - Materialized view is not a read-consistent view of its masters from any point in time

- UNKNOWN - Oracle Database does not know whether the materialized view is in a read-consistent view of its masters from any point in time (this is the case for materialized views created on prebuilt tables)

- UNDEFINED - Materialized view has remote masters. The concept of staleness is not defined for such materialized views.

AFTER_FAST_REFRESH

VARCHAR2(19)

Specifies the staleness value that will occur if a fast refresh is applied to this materialized view. Its values are the same as for the STALENESS column, plus the value NA, which is used when fast refresh is not applicable to this materialized view.

UNKNOWN_TRUSTED_FD

VARCHAR2(1)

Indicates whether the materialized view uses trusted constraints for refresh (Y) or not (N)

COMPILE_STATE

VARCHAR2(19)

Validity of the materialized view with respect to the objects upon which it depends:

- VALID - Materialized view has been validated without error, and no object upon which it depends has changed since the last validation

- NEEDS_COMPILE - Some object upon which the materialized view depends has changed. An ALTER MATERIALIZED VIEW...COMPILE statement is required to validate this materialized view.

- ERROR - Materialized view has been validated with one or more errors

USE_NO_INDEX

VARCHAR2(1)

Indicates whether the materialized view was created using the USING NO INDEX clause (Y) or the materialized view was created with the default index (N). The USING NO INDEX clause suppresses the creation of the default index.

STALE_SINCE

ALL_SYNONYMS

ALL_SYNONYMS describes the synonyms accessible to the current user. The following criteria determine the list of synonyms that ALL_SYNONYMS shows:

- All private synonyms owned by the logged-in user, even if the base object pointed to is not accessible.

- All public synonyms, even if the base object pointed to is not accessible.

- All private synonyms owned by a different user, where the ultimate base object pointed to by that synonym or by any chain of nested synonyms, is know to be accessible because of a grant to the logged-in user, or a grant to a role in effect for this session.

- If the current session has any of the following privileges, then all synonyms that point directly to local objects are shown because it is assumed that the session can access those objects:

- LOCK ANY TABLE

- SELECT ANY TABLE

- INSERT ANY TABLE

- UPDATE ANY TABLE

- DELETE ANY TABLE

Synonyms that point to remote objects are excluded because the system privileges just listed do not automatically convey access to those remote objects. Also, if the synonyms point to objects other than tables and views (such as sequences, PL/SQL procedures, and so on) then this rule may show synonyms that ultimately resolve to objects that this session cannot access.

- All private synonyms owned by a different user, where the synonym is via a database link, are excluded.

Number of redo blocks that need to be processed during recovery to satisfy the LOG_CHECKPOINT_TIMEOUT parameter. The value displayed is not meaningful unless LOG_CHECKPOINT_TIMEOUT has been set.

LOG_CHKPT_INTERVAL_REDO_BLKS

NUMBER

Number of redo blocks that need to be processed during recovery to satisfy the LOG_CHECKPOINT_INTERVAL parameter. The value displayed is not meaningful unless LOG_CHECKPOINT_INTERVAL has been set.

FAST_START_IO_TARGET_REDO_BLKS

NUMBER

This column is obsolete and maintained for backward compatibility. The value of this column is always null.

TARGET_MTTR

NUMBER

Effective MTTR (mean time to recover) target value in seconds. The TARGET_MTTR value is calculated based on the value of the FAST_START_MTTR_TARGET parameter (the TARGET_MTTR value is used internally), and is usually an approximation of the parameter's value. However, if the FAST_START_MTTR_TARGET parameter value is very small (for example, one second), or very large (for example, 3600 seconds), then the calculation will produce a target value dictated by system limitations.
In such cases, the TARGET_MTTR value will be the shortest calculated time, or the longest calculated time that recovery is expected to take. If FAST_START_MTTR_TARGET is not specified, then the value of this field is the current estimated MTTR.

ESTIMATED_MTTR

NUMBER

Current estimated mean time to recover (MTTR) based on the number of dirty buffers and log blocks (0 if FAST_START_MTTR_TARGET is not specified). This value tells you how long you can expect recovery to take based on the work the system is doing right now.

CKPT_BLOCK_WRITES

NUMBER

Number of blocks written by checkpoint writes

OPTIMAL_LOGFILE_SIZE

NUMBER

Redo log file size (in megabytes) that is considered optimal based on the current setting of FAST_START_MTTR_TARGET. It is recommended that all online redo logs be configured to be at least this value.

ESTD_CLUSTER_AVAILABLE_TIME

NUMBER

Estimated time (in seconds) that the cluster would become partially available should the instance fail. This column is only meaningful in an Oracle Real Application Clusters (Oracle RAC) environment. In a non-Oracle RAC environment, the value of this column is null.

WRITES_MTTR

NUMBER

Number of writes driven by the FAST_START_MTTR_TARGET parameter

WRITES_LOGFILE_SIZE

NUMBER

Number of writes driven by the smallest redo log file size

WRITES_LOG_CHECKPOINT_SETTINGS

NUMBER

NUMBER

Number of writes driven by other reasons (such as the deprecated FAST_START_IO_TARGET parameter)

WRITES_AUTOTUNE

NUMBER

Number of writes due to auto-tune checkpointing

WRITES_FULL_THREAD_CKPT

NUMBER

Number of writes due to full thread checkpoints

DBA_HIST_INTERCONNECT_PINGS

DBA_HIST_INTERCONNECT_PINGS displays information about measured latency of interconnect messages (round-trip) from instance to instance. In Oracle Database 11g, the PING process assesses the latencies associated with communications for each pair of instances.

Every few seconds, the process in one instance (INSTANCE_NUMBER value) sends two messages to each instance (TARGET_INSTANCE value). One message has a size of 500 bytes and the other has a size of 8 KB. The message is received by the PING process on the target instance and is immediately acknowledged. The time for the round-trip is measured and collected.

Part III

Dynamic Performance Views

This part describes the dynamic performance views, which are often referred to as V$ views. This part contains the following chapters:

- Chapter 7, "Dynamic Performance (V$) Views: V$ACCESS to V$HVMASTER_INFO"

- Chapter 8, "Dynamic Performance (V$) Views: V$INDEXED_FIXED_COLUMN to V$RULE_SET_AGGREGATE_STATS"

- Chapter 9, "Dynamic Performance (V$) Views: V$SCHEDULER_RUNNING_JOBS to V$XSTREAM_TRANSACTION"

7 Dynamic Performance (V$) Views: V$ACCESS to V$HVMASTER_INFO

This chapter describes the first set (in alphabetical order) of dynamic performance views. The remaining dynamic performance views appear in alphabetical order in Chapter 8 through Chapter 9.

This chapter contains the following topics:

- About Dynamic Performance Views

- Dynamic Performance View Descriptions

About Dynamic Performance Views

Oracle contains a set of underlying views that are maintained by the database server and accessible to the database administrator user SYS. These views are called dynamic performance views because they are continuously updated while a database is open and in use, and their contents relate primarily to performance.

Although these views appear to be regular database tables, they are not. These views provide data on internal disk structures and memory structures. You can select from these views, but you can never update or alter them.

Note:

- You can query the dynamic performance views to extract information from them. However, only simple queries are supported. If sorts, joins, GROUP BY clauses and the like are needed, then you should copy the information from each V$ view into a table (for example, using a CREATE TABLE ... AS SELECT statement), and then query from those tables.

- Because the information in the V$ views is dynamic, read consistency is not guaranteed for SELECT operations on these views.

The catalog.sql script contains definitions of the views and public synonyms for the dynamic performance views. You must run catalog.sql to create these views and synonyms. After installation, only user SYS or anyone with SYSDBA role has access to the dynamic performance tables. See Oracle Database Administrator's Guide for more information about running catalog.sql.

V$ Views

The actual dynamic performance views are identified by the prefix V_$. Public synonyms for these views have the prefix V$. Database administrators and other users should access only the V$ objects, not the V_$ objects.

The dynamic performance views are used by Oracle Enterprise Manager, which is the primary interface for accessing information about system performance. After an instance is started, the V$ views that read from memory are accessible. Views that read data from disk require that the database be mounted, and some require that the database be open.

GV$ Views

For almost every V$ view described in this chapter, Oracle has a corresponding GV$ (global V$) view. In Real Application Clusters, querying a GV$ view retrieves the V$ view information from all qualified instances. In addition to the V$ information, each GV$ view contains an extra column named INST_ID of datatype NUMBER. The INST_ID column displays the instance number from which the associated V$ view information was obtained. The INST_ID column can be used as a filter to retrieve V$ information from a subset of available instances. For example, the following query retrieves the information from the V$LOCK view on instances 2 and 5:

SQL> SELECT * FROM GV$LOCK WHERE INST_ID = 2 OR INST_ID = 5;

STATE

VARCHAR2(8)

Global state of the disk with respect to the disk group:

- UNKNOWN - Automatic Storage Management disk state is not known (typically the disk is not mounted)

- NORMAL - Disk is online and operating normally

- ADDING - Disk is being added to a disk group, and is pending validation by all instances that have the disk group mounted

Indicates whether this corruption was not previously detected by the Oracle Database (YES) or the Oracle Database had already discovered this corrupt block and marked it as corrupt (NO). Note that when a corrupt block is encountered in a backup, and was not already marked corrupt by the Oracle Database, then the backup process does not mark the block as corrupt in the production datafile. Thus, this field may be YES for the same block in more than one backup set.

CORRUPTION_TYPE

VARCHAR2(9)

Type of block corruption in the datafile:

- ALL ZERO - Block header on disk contained only zeros. The block may be valid if it was never filled and if it is in an Oracle7 file. The buffer will be reformatted to the Oracle8 standard for an empty block.

- FRACTURED - Block header looks reasonable, but the front and back of the block are different versions.

- CHECKSUM - optional check value shows that the block is not self-consistent. It is impossible to determine exactly why the check value fails, but it probably fails because sectors in the middle of the block are from different versions.

- CORRUPT - Block is wrongly identified or is not a data block (for example, the data block address is missing)

- LOGICAL - Block is logically corrupt

- NOLOGGING - Block does not have redo log entries (for example, NOLOGGING operations on primary database can introduce this type of corruption on a physical standby)

Current statistics use samples collected over the most recent time-to-live interval.

- Historical statistics (AVG_ and most of the MAX_ columns)
Historical statistics make use of all samples that are no longer current.

At the time of collection, a sample is current. After the time-to-live has elapsed, the sample becomes historical. Each type of activity has a specific scale (represented by the SCALE_* columns) at which the statistics are reported.

V$INSTANCE_CACHE_TRANSFER

V$INSTANCE_CACHE_TRANSFER displays statistics for the cache blocks transferred among instances.

Oracle keeps multiple versions of data buffered in the buffer cache. The current buffer (or block), CURRENT_BLOCK, is the most up-to-date copy, containing all recent modifications. A consistent read buffer (or block), CR_BLOCK, contains the version of the data at a particular time prior to the current buffer. It is read-consistent (that is, all the data shown in that buffer are consistent for the start time of a query).

Therefore, for the same data block there can be multiple copies in the buffer cache: one current copy, and one or more consistent read copies with data consistent as of different snapshot times.

- Set the FAST_START_MTTR_TARGET initialization parameter

- Set the size of the smallest redo log

Column

Datatype

Description

RECOVERY_ESTIMATED_IOS

NUMBER

Number of dirty buffers in the buffer cache. In the Standard Edition, this column is always null.

ACTUAL_REDO_BLKS

NUMBER

Current actual number of redo blocks required for recovery

TARGET_REDO_BLKS

NUMBER

Current target number of redo blocks that must be processed for recovery. This value is the minimum value of the following 3 columns, and identifies which of the 3 user-defined limits determines checkpointing.

LOG_FILE_SIZE_REDO_BLKS

LOG_CHKPT_INTERVAL_REDO_BLKS

NUMBER

Number of redo blocks that need to be processed during recovery to satisfy the LOG_CHECKPOINT_INTERVAL parameter. The value displayed is not meaningful unless that parameter has been set.

FAST_START_IO_TARGET_REDO_BLKS

NUMBER

This column is obsolete and maintained for backward compatibility. The value of this column is always null.

TARGET_MTTR

NUMBER

Effective MTTR (mean time to recover) target value in seconds. The TARGET_MTTR value is calculated based on the value of the FAST_START_MTTR_TARGET parameter (the TARGET_MTTR value is used internally), and is usually an approximation of the parameter's value. However, if the FAST_START_MTTR_TARGET parameter value is very small (for example, one second), or very large (for example, 3600 seconds), the calculation will produce a target value dictated by system limitations. In such cases, the TARGET_MTTR value will be the shortest calculated time, or the longest calculated time that recovery is expected to take.
If FAST_START_MTTR_TARGET is not specified, the value of this field is the current estimated MTTR.

ESTIMATED_MTTR

NUMBER

Current estimated mean time to recover (MTTR) based on the number of dirty buffers and log blocks (0 if FAST_START_MTTR_TARGET is not specified). Basically, this value tells you how long you could expect recovery to take based on the work your system is doing right now.

CKPT_BLOCK_WRITES

NUMBER

Number of blocks written by checkpoint writes

OPTIMAL_LOGFILE_SIZE

NUMBER

Redo log file size (in megabytes) that is considered optimal based on the current setting of FAST_START_MTTR_TARGET. It is recommended that the user configure all online redo logs to be at least this value. Note that redo log files must be at least 4 megabytes in size; otherwise an error is generated.

ESTD_CLUSTER_AVAILABLE_TIME

NUMBER

Estimated time (in seconds) that the cluster would become partially available should this instance fail. This column is only meaningful in an Oracle Real Application Clusters (Oracle RAC) environment. In a non-Oracle RAC environment, the value of this column is null.

WRITES_MTTR

NUMBER

Number of writes driven by the FAST_START_MTTR_TARGET initialization parameter

WRITES_LOGFILE_SIZE

NUMBER

Number of writes driven by the smallest redo log file size

WRITES_LOG_CHECKPOINT_SETTINGS

NUMBER

Number of writes driven by the LOG_CHECKPOINT_INTERVAL or LOG_CHECKPOINT_TIMEOUT initialization parameter

WRITES_OTHER_SETTINGS

WRITES_AUTOTUNE

NUMBER

Number of writes due to auto-tune checkpointing

WRITES_FULL_THREAD_CKPT

V$MTTR_TARGET_ADVICE

V$MTTR_TARGET_ADVICE displays rows that predict the number of physical I/Os for the MTTR corresponding to each row. The rows also compute a physical I/O factor, which is the ratio of the number of estimated I/Os to the number of I/Os actually performed by the current MTTR setting during the measurement interval.

The content of the view is empty if MTTR advisory has not been turned on since database startup. Otherwise, it returns the advisory information collected. If advisory is currently off, then this information comes from the last time MTTR advisory was on. FAST_START_MTTR_TARGET must be set to a nonzero value if the STATISTICS_LEVEL parameter is dynamically modified to turn MTTR advisory on.

If the FAST_START_MTTR_TARGET parameter is changed while MTTR advisory is on, then MTTR advisory is temporarily turned off until the new FAST_START_MTTR_TARGET setting takes effect. During this transition period, the contents of V$MTTR_TARGET_ADVICE reflect the simulation result for the old MTTR setting.

V$PGA_TARGET_ADVICE

V$PGA_TARGET_ADVICE predicts how the cache hit percentage and over allocation count statistics displayed by the V$PGASTAT performance view would be impacted if the value of the PGA_AGGREGATE_TARGET parameter is changed. The prediction is performed for various values of the PGA_AGGREGATE_TARGET parameter, selected around its current value. The advice statistic is generated by simulating the past workload run by the instance.

The content of the view is empty if PGA_AGGREGATE_TARGET is not set. In addition, the content of this view is not updated if the STATISTICS_LEVEL parameter is set to BASIC. Base statistics for this view are reset at instance startup and when the value of the PGA_AGGREGATE_TARGET initialization parameter is dynamically modified.

Column

PGA_TARGET_FACTOR

NUMBER

PGA_TARGET_FOR_ESTIMATE / the current value of the PGA_AGGREGATE_TARGET parameter

ADVICE_STATUS

Total bytes processed by all the work areas considered by this advice (in bytes)

ESTD_TIME

NUMBER

Time (in seconds) required to process the bytes

ESTD_EXTRA_BYTES_RW

NUMBER

Estimated number of extra bytes which would be read or written if PGA_AGGREGATE_TARGET was set to the value of the PGA_TARGET_FOR_ESTIMATE column. This number is derived from the estimated number and size of work areas which would run in one-pass (or multi-pass) for that value of PGA_AGGREGATE_TARGET.

ESTD_PGA_CACHE_HIT_PERCENTAGE

NUMBER

Estimated value of the cache hit percentage statistic when PGA_AGGREGATE_TARGET equals PGA_TARGET_FOR_ESTIMATE. This column is derived from the above two columns and is equal to BYTES_PROCESSED / (BYTES_PROCESSED + ESTD_EXTRA_BYTES_RW)

ESTD_OVERALLOC_COUNT

NUMBER

Estimated number of PGA memory over-allocations if the value of PGA_AGGREGATE_TARGET is set to PGA_TARGET_FOR_ESTIMATE. A nonzero value means that PGA_TARGET_FOR_ESTIMATE is not large enough to run the work area workload. Hence, the DBA should not set PGA_AGGREGATE_TARGET to PGA_TARGET_FOR_ESTIMATE since Oracle will not be able to honor that target.

Table 8-4 V$PGASTAT Statistics

Statistic Name

Description

aggregate PGA auto target

Amount of PGA memory the Oracle Database can use for work areas running in automatic mode. This amount is dynamically derived from the value of the PGA_AGGREGATE_TARGET initialization parameter and the current work area workload, and continuously adjusted by the Oracle Database.

If this value is small compared to the value of PGA_AGGREGATE_TARGET, then a large amount of PGA memory is used by other components of the system (for example, PL/SQL or Java memory) and little is left for work areas. The DBA must ensure that enough PGA memory is left for work areas running in automatic mode.

aggregate PGA target parameter

Current value of the PGA_AGGREGATE_TARGET initialization parameter. If this parameter is not set, then its value is 0 and automatic management of PGA memory is disabled.

bytes processed

Number of bytes processed by memory intensive SQL operators, cumulated since instance startup.

cache hit percentage

A metric computed by the Oracle Database to reflect the performance of the PGA memory component, cumulative since instance startup. A value of 100% means that all work areas executed by the system since instance startup have used an optimal amount of PGA memory.

When a work area cannot run optimal, one or more extra passes is performed over the input data. This will reduce the cache hit percentage in proportion to the size of the input data and the number of extra passes performed.

extra bytes read/written

Number of bytes processed during extra passes of the input data, cumulated since instance startup. When a work area cannot run optimal, one or more of these extra passes is performed.

global memory bound

Maximum size of a work area executed in automatic mode. This value is continuously adjusted by the Oracle Database to reflect the current state of the work area workload. The global memory bound generally decreases when the number of active work areas is increasing in the system.

If the value of the global bound decreases below 1 MB, then the value of PGA_AGGREGATE_TARGET should be increased.

max processes count

Maximum number of processes active at any one time since instance startup.

maximum PGA allocated

Maximum number of bytes of PGA memory allocated at one time since instance startup.

maximum PGA used for auto workareas

Maximum amount of PGA memory consumed at one time by work areas running under the automatic memory management mode since instance startup.

maximum PGA used for manual workareas

Maximum amount of PGA memory consumed at one time by work areas running under the manual memory management mode since instance startup.

over allocation count

This statistic is cumulative since instance startup. Over allocating PGA memory can happen if the value of PGA_AGGREGATE_TARGET is too small. When this happens, the Oracle Database cannot honor the value of PGA_AGGREGATE_TARGET and extra PGA memory needs to be allocated.

If over allocation occurs, then increase the value of PGA_AGGREGATE_TARGET using the information provided by the V$PGA_TARGET_ADVICE view.

PGA memory freed back to OS

Number of bytes of PGA memory freed back to the operating system, cumulated since instance startup.

process count

Number of processes active within up to the last 3 seconds.

recompute count (total)

Number of times the instance bound, which is a cap on the maximum size of each active work area, has been recomputed since instance startup. Generally, the instance bound is recomputed in the background every 3 seconds, but it could be recomputed by a foreground process when the number of work areas changes rapidly in a short period of time.

total freeable PGA memory

Number of bytes of PGA memory in all processes that could be freed back to the operating system.

total PGA allocated

Current amount of PGA memory allocated by the instance. The Oracle Database attempts to keep this number below the value of the PGA_AGGREGATE_TARGET initialization parameter. However, it is possible for the PGA allocated to exceed that value by a small percentage and for a short period of time when the work area workload is increasing very rapidly or when PGA_AGGREGATE_TARGET is set to a small value.

total PGA inuse

Indicates how much PGA memory is currently consumed by work areas. This number can be used to determine how much memory is consumed by other consumers of the PGA memory (for example, PL/SQL or Java).

total PGA used for auto workareas

Indicates how much PGA memory is currently consumed by work areas running under the automatic memory management mode. This number can be used to determine how much memory is consumed by other consumers of the PGA memory (for example, PL/SQL or Java).

total PGA used for manual workareas

Indicates how much PGA memory is currently consumed by work areas running under the manual memory management mode. This number can be used to determine how much memory is consumed by other consumers of the PGA memory (for example, PL/SQL or Java).

Use this view to determine which transactions are currently being propagated, the number of calls propagated in each transaction, and the current activity of the parallel propagation slave processes or parallel propagation coordinator process.

Column

Datatype

Description

SID

NUMBER

Session identifier

SERIAL#

NUMBER

Session serial number. Used to identify uniquely a session's objects. Guarantees that session-level commands are applied to the correct session objects if the session ends with, and another session begins with, the same session ID.

NAME

VARCHAR2(71)

Name of the propagation session:

- Replication Parallel Prop Slaven - Slave process n is active, either waiting, pushing deferred transactions, purging metadata, or creating an error transaction

- Replication Parallel Prop Coordinator - Coordinator process is active, and either waiting, sleeping, or scheduling slaves to perform operations

The coordinator process reads transactions from the deferred transaction queue and assigns them to the slave processes. Then, the slaves propagate the transactions to the destination site. When the slaves push transactions in a push session, the slaves remain active until the push session completes, even if there are no more transactions to push.

DBLINK

VARCHAR2(128)

Database link on which this replication session is propagating

STATE

VARCHAR2(12)

State of the propagation session:

- WAIT - Slave processes or the coordinator process is waiting for an event (that is, a message)

- SLEEP - Coordinator process is sleeping for the duration of the delay_seconds setting.
Note: delay_seconds is set with the DBMS_DEFER_SYS.SCHEDULE_PUSH procedure.

- PUSH - Slave processes are pushing transactions from the deferred transaction queue to the remote site

- PURGE - Slave processes are purging metadata related to successfully applied transactions from the remote site

- CREATE ERROR - Slave processes are creating an error transaction. In this case, an error or a conflict occurred while the slaves were pushing deferred transactions to the remote site.

- SCHEDULE TXN - Coordinator process is determining the order that transactions are applied and assigning slave processes to execute the transactions

XID

VARCHAR2(22)

If the session is a slave session, then indicates the transaction id of the transaction that the slave is currently propagating.

SEQUENCE

NUMBER

If the process is a slave process, then indicates the sequence number of the calls propagated in the current operation, if relevant. Each transaction must process one or more calls, and the value of SEQUENCE starts at zero and increases as each call is processed. The SEQUENCE value shows the call that is currently being processed in each transaction. This value increases until the slave has processed all of the calls in a transaction.

Note:

This view only contains data when deferred transactions are being pushed using parallel propagation at the current site. The parallelism parameter must be set to 1 or higher in the DBMS_DEFER_SYS.PUSH function for a push to use parallel propagation. Otherwise, the push uses serial propagation, and no data appears in this view during the push.

V$RESOURCE_LIMIT

V$RESOURCE_LIMIT displays information about global resource use for some of the system resources. Use this view to monitor the consumption of resources so that you can take corrective action, if necessary. Many of the resources correspond to initialization parameters listed in Table 8-5.

Some resources, those used by DLM for example, have an initial allocation (soft limit), and the hard limit, which is theoretically infinite (although in practice it is limited by SGA size). During SGA reservation/initialization, a place is reserved in SGA for the INITIAL_ALLOCATION of resources, but if this allocation is exceeded, additional resources are allocated up to the value indicated by LIMIT_VALUE. The CURRENT_UTILIZATION column indicates whether the initial allocation has been exceeded. When the initial allocation value is exceeded, the additional required resources are allocated from the shared pool, where they must compete for space with other resources.

A good choice for the value of INITIAL_ALLOCATION will avoid the contention for space. For most resources, the value for INITIAL_ALLOCATION is the same as the LIMIT_VALUE. Exceeding LIMIT_VALUE results in an error.

repeated bind elapsed time

Amount of elapsed time spent giving new values to bind variables (rebinding).

The relationships between the statistics listed in Table 9-1 form two trees in which all the time reported by a child in the tree is contained within the parent in the tree. The following are the relationship trees; the number is the level in the given tree.

1) background elapsed time
2) background cpu time
3) RMAN cpu time (backup/restore)
1) DB time
2) DB CPU
2) connection management call elapsed time
2) sequence load elapsed time
2) sql execute elapsed time
2) parse time elapsed
3) hard parse elapsed time
4) hard parse (sharing criteria) elapsed time
5) hard parse (bind mismatch) elapsed time
3) failed parse elapsed time
4) failed parse (out of shared memory) elapsed time
2) PL/SQL execution elapsed time
2) inbound PL/SQL rpc elapsed time
2) PL/SQL compilation elapsed time
2) Java execution elapsed time
2) repeated bind elapsed time

The relationship between a parent and a child in the tree indicates containment only. Keep the following in mind with regard to the tree:

- Children do not necessarily add up to the parent.

- Children are not necessarily exclusive (that is, it is possible that they overlap).

- The union of children does not necessarily cover the whole of the parent.

V$SQL_MONITOR

V$SQL_MONITOR displays SQL statements whose execution have been (or are being) monitored by Oracle. An entry is created in V$SQL_MONITOR every time the execution of a SQL statement is being monitored. SQL monitoring is automatically started when a SQL statement runs parallel or when it has consumed at least 5 seconds of CPU or I/O time.

When the SQL statement being monitored is executing, statistics in V$SQL_MONITOR are generally refreshed in near real time, once every second. Once the execution ends, monitoring information is not deleted immediately. Instead, it is kept in V$SQL_MONITOR for at least one minute. The entry will eventually be deleted to reclaim its space as new statements are monitored.

V$SQL_PLAN_MONITOR

V$SQL_PLAN_MONITOR displays plan level monitoring statistics for each SQL statement found in V$SQL_MONITOR. Each row in V$SQL_PLAN_MONITOR corresponds to an operation of the execution plan being monitored. As with V$SQL_MONITOR, statistics exposed in V$SQL_PLAN_MONITOR are generally updated every second when the statement executes. These statistics are recycled on the same basis as V$SQL_MONITOR.

To eliminate the overhead of SQL plan monitoring, statistics collected for each operation of the plan don't record timing information such as elapsed time, CPU time, or I/O time. Instead, this timing information can be estimated quite accurately by joining V$SQL_PLAN_MONITOR with V$ACTIVE_SESSION_HISTORY on SQL_ID, SQL_EXEC_START, SQL_EXEC_ID, and SQL_PLAN_LINE_ID (simply named PLAN_LINE_ID in V$SQL_PLAN_MONITOR). The result of that join is a sample of the activity performed by each operation in the plan, from which an estimate of CPU time and wait time can be derived. This can be achieved by breaking statement level monitoring time statistics found in V$SQL_MONITOR in proportion to the number of samples found in V$ACTIVE_SESSION_HISTORY for the corresponding activity type.

V$SYS_OPTIMIZER_ENV

V$SYS_OPTIMIZER_ENV displays the contents of the optimizer environment for the instance. The optimizer environment stores the value of the main parameters used by the Oracle optimizer when building the execution plan of a SQL statement. Hence, modifying the value of one or more of these parameters (for example, by issuing an ALTER SYSTEM statement) could lead to plan changes.

The parameters displayed by this view are either regular initialization parameters (such as OPTIMIZER_FEATURES_ENABLE) or pseudo parameters (such as ACTIVE_INSTANCE_COUNT).

V$SYS_TIME_MODEL

V$SYS_TIME_MODEL displays the system-wide accumulated times for various operations. The time reported is the total elapsed or CPU time (in microseconds). Any timed operation will buffer at most 5 seconds of time data. Specifically, this means that if a timed operation (such as SQL execution) takes a long period of time to perform, the data published to this view is at most missing 5 seconds of the time accumulated for the operation.

The time values are 8-byte integers and can therefore hold approximately 580,000 years worth of time before wrapping. Background process time is not included in a statistic value unless the statistic is specifically for background processes.

V$UNDOSTAT

V$UNDOSTAT displays a histogram of statistical data to show how well the system is working. The available statistics include undo space consumption, transaction concurrency, and length of queries executed in the instance. You can use this view to estimate the amount of undo space required for the current workload. Oracle uses this view to tune undo usage in the system. The view returns NULL values if the system is in manual undo management mode.

Each row in the view keeps statistics collected in the instance for a 10-minute interval. The rows are in descending order by the BEGIN_TIME column value. Each row belongs to the time interval marked by (BEGIN_TIME, END_TIME). Each column represents the data collected for the particular statistic in that time interval. The first row of the view contains statistics for the (partial) current time period. The view contains a total of 576 rows, spanning a 4 day cycle.

- LOADING (step X of Y) - Processing information from a dictionary build and currently at step X in a process that involves Y steps, where X and Y are numbers.

- CAPTURING CHANGES - Scanning the redo log for changes that satisfy the capture process rule sets.

- WAITING FOR REDO - Waiting for new redo log files to be added to the capture process session. The capture process has finished processing all of the redo log files added to its session. This state is possible if there is no activity at a source database. For a downstream capture process, this state is possible if the capture process is waiting for new log files to be added to its session.

- EVALUATING RULE - Evaluating a change against a capture process rule set.

- CREATING LCR - Converting a change into an LCR.

- ENQUEUING MESSAGE - Enqueuing an LCR that satisfies the capture process rule sets into the capture process queue.

- PAUSED FOR FLOW CONTROL - Unable to enqueue LCRs either because of low memory or because propagations and outbound servers are consuming messages slower than the capture process is creating them. This state indicates flow control that is used to reduce spilling of captured LCRs when propagation or apply has fallen behind or is unavailable.

- WAITING FOR THE BUFFERED QUEUE TO SHRINK - Waiting for the buffered queue to change to a smaller size. The buffered queue shrinks when there is a memory limitation or when an administrator reduces its size.

- WAITING FOR n SUBSCRIBER(S) INITIALIZING - Waiting for outbound servers that receive LCRs from the capture process to start, where n is the number of apply processes.

- WAITING FOR TRANSACTION - Waiting for LogMiner to provide more transactions.

- WAITING FOR INACTIVE DEQUEUERS - Waiting for the capture process's queue subscribers to start. The capture process stops enqueuing LCRs if there are no active subscribers to the queue.

- SUSPENDED FOR AUTO SPLIT/MERGE - Waiting for a merge operation to complete.

- SHUTTING DOWN - Stopping.

- ABORTING - Aborting.

Column

Datatype

Description

SID

NUMBER

Session ID of the outbound server's session

SERIAL#

NUMBER

Serial number of the outbound server's session

SPID

VARCHAR2(12)

Process identification number of the operating-system process that sends LCRs to the client application

SERVER_NAME

VARCHAR2(30)

Name of the outbound server

STARTUP_TIME

DATE

STATE

VARCHAR2(37)

State of the outbound server
When the COMMITTED_DATA_ONLY column shows YES, the following states are possible:

- INITIALIZING - Starting up the outbound server.

- IDLE - Performing no work because there are no LCRs to send to the XStream client application.

- GET TRANSACTIONS - Receiving transactions from the outbound server's apply coordinator.

- SEND TRANSACTION - Sending a transaction to an XStream client application.

- WAIT FOR NEXT CHUNK - Waiting for the next set of LCRs for a large transaction.

- TRANSACTION CLEANUP - Cleaning up an applied transaction, which includes removing LCRs from the outbound server's queue.

- WAIT FOR CLIENT - Waiting for an XStream client application to request more LCRs.

When the COMMITTED_DATA_ONLY column shows NO, the following states are possible:

- INITIALIZING - Starting up the outbound server.

- INITIALIZING RULE EVALUATION CONTEXT - Initializing the context to evaluate the outbound server's rules.

- IDLE - Performing no work because there is no LCR to send to the XStream client application.

- BROWSING LCR - Browsing the outbound server's queue for next LCR.

- EVALUATING RULES - Evaluating an LCR against a rule set.

- DEQUEUING LCR - Dequeuing an LCR from the outbound server's queue.

- SENDING LCR - Sending an LCR to an XStream client application.

- WAITING FOR CAPTURE TO TERMINATE - Waiting for the capture process to become disabled.

- SUSPENDED DUE TO A DROPPED SUBSCRIBER - Suspended because a connected subscriber was dropped. For example, a subscriber can be dropped during a split or merge operation.

- SUSPENDED FOR AUTO SPLIT/MERGE - Suspended because an automatic split or merge operation is being performed.

- WAITING ON EMPTY QUEUE - Waiting for more LCRs from the capture process.

- WAITING FOR CLIENT - Waiting for the XStream client application to request more LCRs.

- WAITING FOR CAPTURE TO INITIALIZE - Waiting for the capture process to finish the data dictionary build.

- WAITING TO ATTACH TO CAPTURE - Waiting for the outbound server to attach to the capture process.

When a state refers to a capture process, it is the capture process that captures changes for the outbound server. When a state refers to a propagation, it is the outbound server that sends LCRs to the XStream client application.

A Database Limits

This appendix lists the limits of values associated with database functions and objects. Limits exist on several levels in the database. There is usually a hard-coded limit in the database that cannot be exceeded. This value may be further restricted for any given operating system.

Database limits are divided into four categories:

- Datatype Limits

- Physical Database Limits

- Logical Database Limits

- Process and Runtime Limits

Footnote 1 The absolute maximum number of columns in a table is 1000. However, when you create an object table (or a relational table with columns of object, nested table, varray, or REF type), Oracle maps the columns of the user-defined types to relational columns, creating in effect hidden columns that count toward the 1000-column limit. For details on how Oracle calculates the total number of columns in such a table, refer to Oracle Database Administrator's Guide.

B SQL Scripts

This appendix describes SQL scripts that are required for optimal operation of the Oracle Database.

The SQL scripts are described in the following sections:

- Creating the Data Dictionary

- Creating Additional Data Dictionary Structures

- The "NO" Scripts

- Upgrade and Downgrade Scripts

- Java Scripts

Note:

Comments within the SQL scripts themselves contain more detailed information and examples.

Creating the Data Dictionary

When you use the Database Configuration Assistant to create a database, Oracle automatically creates the data dictionary. Thereafter, whenever the database is in operation, Oracle updates the data dictionary in response to every DDL statement.

The data dictionary base tables are the first objects created in any Oracle database. They are created in the SYSTEM tablespace and must remain there. The data dictionary base tables store information about all user-defined objects in the database.

Table B-1 lists required scripts, which are run automatically when you create a database using the Database Configuration Assistant. They are described here because you might need to run them if you create a database manually. To run these scripts, you must be connected to Oracle as a user with SYSDBA privileges.

C Oracle Wait Events

This appendix contains the following topics:

- Classes of Wait Events

- Descriptions of Common Wait Event Parameters

- Descriptions of Wait Events

Information about wait events is displayed in three dynamic performance views:

- V$SESSION_WAIT displays the events for which sessions have just completed waiting or are currently waiting.

- V$SYSTEM_EVENT displays the total number of times all the sessions have waited for the events in that view.

- V$SESSION_EVENT is similar to V$SYSTEM_EVENT, but displays all waits for each session.

See Also:

"V$SESSION_EVENT", "V$SESSION_WAIT", and "V$SYSTEM_EVENT"

Many of these wait events are tied to the internal implementation of Oracle and therefore are subject to change or deletion without notice. Application developers should be aware of this and write their code to tolerate missing or extra wait events.

The following SQL statement displays an alphabetical list of all Oracle wait events and the wait class to which they belong:

SQL> SELECT name, wait_class FROM V$EVENT_NAME ORDER BY name;

Classes of Wait Events

Every wait event belongs to a class of wait event. The following list describes each of the wait classes.

Administrative

Waits resulting from DBA commands that cause users to wait (for example, an index rebuild)

Application

Waits resulting from user application code (for example, lock waits caused by row level locking or explicit lock commands)

Cluster

Waits related to Real Application Clusters resources (for example, global cache resources such as 'gc cr block busy')

Commit

This wait class only comprises one wait event - wait for redo log write confirmation after a commit (that is, 'log file sync')

Concurrency

Waits for internal database resources (for example, latches)

Configuration

Waits caused by inadequate configuration of database or instance resources (for example, undersized log file sizes, shared pool size)

Idle

Waits that signify the session is inactive, waiting for work (for example, 'SQL*Net message from client')

Network

Waits related to network messaging (for example, 'SQL*Net more data to dblink')

Other

Waits which should not typically occur on a system (for example, 'wait for EMON to spawn')

Queue

Contains events that signify delays in obtaining additional data in a pipelined environment. The time spent on these wait events indicates inefficiency or other problems in the pipeline. It affects features such as Oracle Streams, parallel queries, or DBMS_PIPE PL/SQL packages.

Scheduler

Resource Manager related waits (for example, 'resmgr: become active')

System I/O

Waits for background process I/O (for example, DBWR wait for 'db file parallel write')

User I/O

Waits for user I/O (for example 'db file sequential read')

Descriptions of Common Wait Event Parameters

This section provides descriptions of some of the more common wait event parameters.

block#

This is the block number of the block for which Oracle needs to wait. The block number is relative to the start of the file. To find the object to which this block belongs, issue the following SQL statement:

select segment_name, segment_type, owner, tablespace_name
from dba_extents
where file_id = file#
and block#
between block_id and block_id + blocks - 1;

blocks

The number of blocks that is being either read from or written to the file. The block size is dependent on the file type:

- Database files have a block size of DB_BLOCK_SIZE

- Logfiles and control files have a block size that is equivalent to the physical block size of the platform

break?

If the value for this parameter equals 0, a reset was sent to the client. A nonzero value indicates that a break was sent to the client.

class

The class of the block describes how the contents of the block are used. For example, class 1 represents data block, and class 4 represents segment header.

dba

The initials "dba" represents the data block address, which consists of a file number and a block number.

driver id

The address of the disconnect function of the driver that is currently being used.

file#

The following query returns the name of the database file:

select *
from v$datafile
where file# = file#;

id1

The first identifier (id1) of the enqueue or global lock takes its value from P2 or P2RAW. The meaning of the identifier depends on the name (P1).

id2

The second identifier (id2) of the enqueue or global lock takes its value from P3 or P3RAW. The meaning of the identifier depends on the name (P1).

broadcast mesg queue transition

Processes enter "wait for broadcast mesg queue transition" when cleaning up a publisher channel handle to a RELIABLE broadcast channel. The publisher is responsible for moving the message to the free queue, but it cannot do so until the message is in the done queue. If the message is still not in the done queue, process enters this wait. This wait event will most likely show up when an Oracle process is about to exit normally, or when PMON cleans up a dead process.

Wait Time: Varies

Parameter

Description

channel handle

publisher channel handle pointer

message

broadcast message pointer

location

A number indicating the function in KSR where the process is waiting

broadcast mesg recovery queue transition

Processes enter "wait for broadcast mesg recovery queue transition" when cleaning up a publisher channel handle to a RELIABLE broadcast channel. The broadcasted message is in the recovery queue of another channel handle (for example, ch2). Process enters this wait, if the message is yet to be removed from the recovery queue of the ch2 channel handle. This wait event will most likely show up when an Oracle process is about to exit normally, or when PMON cleans up a dead process.

Wait Time: Varies

Parameter

Description

channel handle

Publisher channel handle pointer

message

Broadcast message pointer

location

A number indicating the function in KSR where the process is waiting

buffer busy waits

Wait until a buffer becomes available. This event happens because a buffer is either being read into the buffer cache by another session (and the session is waiting for that read to complete) or the buffer is the buffer cache, but in a incompatible mode (that is, some other session is changing the buffer).

Wait Time: Normal wait time is 1 second. If the session was waiting for a buffer during the last wait, then the next wait will be 3 seconds.

Parameter

Description

file#

See "file#"

block#

See "block#"

id

The buffer busy wait event is called from different places in the session

buffer deadlock

Oracle does not really wait on this event; the foreground only yields the CPU. Thus, the chances of catching this event are very low. This is not an application induced deadlock, but an assumed deadlock by the cache layer. The cache layer cannot get a buffer in a certain mode within a certain amount of time.

Wait Time: 0 seconds. The foreground process only yields the CPU and will usually be placed at the end of the CPU run queue.

Parameter

Description

class

See "class"

mode

See "mode"

flag

The flag points to the internal flags used by the session to get this block

dba

See "dba"

buffer latch

The session waits on the buffer hash chain latch. Primarily used in the dump routines.

Wait Time: 1 second

Parameter

Description

latch addr

The virtual address in the SGA where this latch is located. Use the following statement to find the name of this latch:

select *
from v$latch a, v$latchname b
where addr = latch addr
and a.latch# = b.latch#;

chain#

The index into array of buffer hash chains. When the chain is 0xfffffff, the foreground waits on the LRU latch.

buffer read retry

This event occurs only if the instance is mounted in shared mode (Oracle Real Application Cluster). During the read of the buffer, the contents changed. This means that either:

- The version number, dba, or the incarnation and sequence number stored in the block no longer match

- The checksum on the block does not match the checksum in the block

The block will be re-read (this may fail up to 3 times), then corruption is assumed and the corrupt block is dumped in the trace file.

Wait Time: The wait time is the elapsed time of the read

Parameter

Description

file#

See "file#"

block#

See "block#"

checkpoint completed

A session waits for a checkpoint to complete. This could happen, for example, during a close database or a local checkpoint.

Wait Time: 5 seconds

Parameters: None

cleanup of aborted processes

Wait Time: Usually 3 seconds

Parameter

Description

location

Location of the wait

control file parallel write

This event occurs while the session is writing physical blocks to all control files. This happens when:

- The session starts a control file transaction (to make sure that the control files are up to date in case the session crashes before committing the control file transaction)

- The session commits a transaction to a control file

- Changing a generic entry in the control file, the new value is being written to all control files

Wait Time: The wait time is the time it takes to finish all writes to all control files

Parameter

Description

files

The number of control files to which the session is writing

blocks

The number of blocks that the session is writing to the control file

requests

- Reading the header block

Wait Time: The wait time is the elapsed time of the read

Parameter

Description

file#

The control file from which the session is reading

block#

Block number in the control file from where the session starts to read. The block size is the physical block size of the port (usually 512 bytes, some UNIX ports have 1 or 2 Kilobytes).

blocks

The number of blocks that the session is trying to read

control file single write

This wait is signaled while the control file's shared information is written to disk. This is an atomic operation protected by an enqueue (CF), so that only one session at a time can write to the entire database.

Wait Time: The wait time is the elapsed time of the write

Parameter

Description

file#

This identifies the control file to which the session is currently writing

block#

Block number in the control file where the write begins. The block size is the as the physical block size of the port (usually 512 bytes, some UNIX ports have 1 or 2 Kilobytes).

blocks

Parameter

Description

P1

Hash value of cursor

P2

Mutex value (top 2 bytes contain SID holding mutex in exclusive mode, and bottom two bytes usually hold the value 0)

P3

Mutex where (an internal code locator) OR'd with Mutex Sleeps

cursor: mutex X

The session requests the mutex for a cursor object in exclusive mode, and it must wait because the resource is busy. The mutex is busy because either the mutex is being held in exclusive mode by another session or the mutex is being held shared by one or more sessions. The existing mutex holder(s) must release the mutex before the mutex can be granted exclusively.

Parameter

Description

P1

Hash value of cursor

P2

Mutex value (top 2 bytes contain SID holding mutex in exclusive mode, and bottom two bytes usually hold the value 0)

P3

Mutex where (an internal code locator) OR'd with Mutex Sleeps

cursor: pin S

A session waits on this event when it wants to update a shared mutex pin and another session is currently in the process of updating a shared mutex pin for the same cursor object.  This wait event should rarely be seen because a shared mutex pin update is very fast.

Wait Time: Microseconds

Parameter

Description

P1

Hash value of cursor

P2

Mutex value (top 2 bytes contains SID holding mutex in exclusive mode, and bottom two bytes usually hold the value 0)

P3

Mutex where (an internal code locator) OR'd with Mutex Sleeps

cursor: pin X

A session waits on this event when it is requesting an exclusive mutex pin for a cursor object and it must wait because the resource is busy. The mutex pin for a cursor object can be busy either because a session is already holding it exclusive, or there are one or more sessions which are holding shared mutex pin(s). The exclusive waiter must wait until all holders of the pin for that cursor object have released it, before it can be granted.

Wait Time: Microseconds

Parameter

Description

P1

Hash value of cursor

P2

Mutex value (top 2 bytes contains SID holding mutex in exclusive mode, and bottom two bytes usually hold the value 0)

P3

Mutex where (an internal code locator) OR'd with Mutex Sleeps

DFS db file lock

This event occurs only for the DBWR in Real Application Clusters. Each DBWR of every instance holds a global lock on each file in shared mode. The instance that is trying to offline the file will escalate the global lock from shared to exclusive. This signals the other instances to synchronize their SGAs with the control file before the file can be taken offline. The name of this lock is DF (see Appendix D, "Oracle Enqueue Names" for more information).

Wait Time: 1 second in loop. The DBWR is waiting in a loop (sleep, check) for the other instances to downgrade to NULL mode. During this time, the DBWR cannot perform other tasks such as writing buffers.

Parameter

Description

file

See "file#"

DFS lock handle

The session waits for the lock handle of a global lock request. The lock handle identifies a global lock. With this lock handle, other operations can be performed on this global lock (to identify the global lock in future operations such as conversions or release). The global lock is maintained by the DLM.

Wait Time: The session waits in a loop until it has obtained the lock handle from the DLM. Inside the loop there is a wait of 0.5 seconds.

Parameter

The session needs to get the lock handle.

direct path read

During Direct Path operations the data is asynchronously read from the database files. At some stage the session needs to make sure that all outstanding asynchronous I/O have been completed to disk. This can also happen if during a direct read no more slots are available to store outstanding load requests (a load request could consist of multiple I/Os).

Wait Time: 10 seconds. The session will be posted by the completing asynchronous I/O. It will never wait the entire 10 seconds. The session waits in a tight loop until all outstanding I/Os have completed.

On Unix the fsync command, which synchronizes data to disk, is issued to confirm that all the writes have completed and the data is all on disk.

Wait Time: The time taken for the fsync operation to complete, which normally is the time taken to complete the outstanding I/Os.

Parameters

Description

file#

See "file#"

flags

Flags used for debugging purposes

Wait Time: 1 second

Parameter

Description

waited

Indicates the cumulative wait time. After 5 minutes, the session writes to the alert and trace files to indicate that there might be a problem.

dispatcher timer

This basically means that the dispatcher is idle and waiting for some work to arrive.

Wait Time: 60 seconds

Parameter

Description

sleep time

The intended sleep time. The dispatcher will return to work sooner if it is posted by either data arriving on the network or by a post from a shared server process to send data back to the client.

duplicate cluster key

It is possible for a race condition to occur when creating a new cluster key. If it is found that another process has put the cluster key into the data/index block, then the session waits and retries. The retry should then find a valid cluster key.

Wait Time: 0.01 seconds

Parameter

Description

dba

The dba of the block into which the session is trying to insert a cluster key

flashback buf free by RVWR

This wait event only occurs when Flashback Database is turned on. A session waits for recovery writer (RVWR) to write flashback data to the flashback logs on disk because the buffers are full. Until RVWR can free up the buffers, the session may need to wait.

If this event becomes a top wait event for the database, it is typically because the file system or storage system for the Fast Recovery Area does not support enough bandwidth for Oracle to write the flashback database logs. Refer to the Flashback Database section in Oracle Database Backup and Recovery User's Guide for tuning considerations.

Wait Time: 1 second

Parameters: None

flashback logfile sync

Waits for flashback database data to be written to disk.

Wait Time: Includes RVWR writing the flashback database data and posting this process

Parameters: None

free buffer waits

This will happen if:

- All buffer gets have been suspended. This could happen when a file was read-only and is now read-write. All the existing buffers need to be invalidated since they are not linked to lock elements (needed when mounted parallel (shared)). So cache buffers are not assigned to data block addresses until the invalidation is finished.

- The session moved some dirty buffers to the dirty queue and now this dirty queue is full. The dirty queue needs to be written first. The session will wait on this event and try again to find a free buffer

- This also happens after inspecting free buffer inspected buffers. If no free buffer is found, Oracle waits for one second, and then tries to get the buffer again (depends on the context). For more information, see free buffer inspected.

Wait Time: 1 second

Parameter

Description

file#

See "file#"

block#

See "block#"

free global transaction table entry

The session is waiting for a free slot in the global transaction table (used by the Distributed Database option). It will wait for 1 second and try again.

Wait Time: 1 second

Parameter

Description

tries

free process state object

Used during the creation of a process. The session will scan the process table and look for a free process slot. If none can be found, PMON is posted to check if all the processes currently in the process table are still alive. If there are dead processes, then PMON will clean them and make the process slot available to new processes. The waiting process will then rescan the process table to find the new slot.

Wait Time: 1 second

- One client can prevent other clients from accessing the same object

- The client can maintain a dependency for a long time (for example, no other client can change the object)

This lock is also obtained to locate an object in the library cache.

Wait Time: 3 seconds (1 second for PMON)

Parameter

Description

handle address

Address of the object being loaded

lock address

Address of the load lock being used. This is not the same thing as a latch or an enqueue, it is a State Object.

mode

Indicates the data pieces of the object which need to be loaded

This event manages library cache concurrency. Pinning an object causes the heaps to be loaded into memory. If a client wants to modify or examine the object, the client must acquire a pin after the lock.

Wait Time: 3 seconds (1 second for PMON)

Parameter

Description

handle address

Address of the object being loaded

pin address

Address of the load lock being used. This is not the same thing as a latch or an enqueue, it is basically a State Object.

The V$SESSTAT view displays statistics on a per-session basis and is valid only for the session currently connected. When a session disconnects, all statistics for the session are updated in V$SYSSTAT. The values for the statistics are cleared until the next session uses them.

The V$STATNAME view contains all of the statistics for an Oracle release.

Many of these statistics are tied to the internal implementation of Oracle and therefore are subject to change or deletion without notice, even between patch releases. Application developers should be aware of this and write their code to tolerate missing or extra statistics.

See Also:

"V$SESSTAT", "V$STATNAME", and "V$SYSSTAT" for more information on these views

Statistics Descriptions

This section describes the statistics stored in the V$SESSTAT and V$SYSSTAT views. The statistics are listed here in alphabetical order.

The CLASS column contains a number representing one or more statistics classes. The following class numbers are additive:

- 1, User

- 2, Redo

- 4, Enqueue

- 8, Cache

- 16, OS

- 32, Real Application Clusters

- 64, SQL

- 128, Debug

For example, a class value of 72 represents a statistic that relates to SQL statements and caching.

Some statistics are populated only if the TIMED_STATISTICS initialization parameter is set to true. Those statistics are flagged in the right-hand column.

Table E-1 Database Statistics Descriptions

Name

Class

Description

TIMED_STATISTICS

background checkpoints completed

8

Number of checkpoints completed by the background process. This statistic is incremented when the background process successfully advances the thread checkpoint.

background checkpoints started

8

Number of checkpoints started by the background process. This statistic can be larger than "background checkpoints completed" if a new checkpoint overrides an incomplete checkpoint or if a checkpoint is currently under way. This statistic includes only checkpoints of the redo thread. It does not include:

- Individual file checkpoints for operations such as offline or begin backup

- Foreground (user-requested) checkpoints (for example, performed by ALTER SYSTEM CHECKPOINT LOCAL statements)

background timeouts

128

This is a count of the times where a background process has set an alarm for itself and the alarm has timed out rather than the background process being posted by another process to do some work.

branch node splits

128

Number of times an index branch block was split because of the insertion of an additional value

CPU used by this session

1

Closely related to "consistent changes", this statistic counts the total number of changes that were part of an update or delete operation that were made to all blocks in the SGA. Such changes generate redo log entries and hence become permanent changes to the database if the transaction is committed.

This approximates total database work. It statistic indicates the rate at which buffers are being dirtied (on a per-transaction or per-second basis, for example).

8

Number of requests to DBWR to make some free buffers for the LRU

DBWR revisited being-written buffer

8

Number of times that DBWR tried to save a buffer for writing and found that it was already in the write batch. This statistic measures the amount of "useless" work that DBWR had to do in trying to fill the batch.

Many sources contribute to a write batch. If the same buffer from different sources is considered for adding to the write batch, then all but the first attempt will be "useless" because the buffer is already marked as being written.

DBWR summed scan depth

8

The current scan depth (number of buffers examined by DBWR) is added to this statistic every time DBWR scans the LRU for dirty buffers. Divide by "DBWR lru scans" to find the average scan depth.

Total number of data blocks written to disk from the buffer cache. This is a subset of "physical writes" statistic.

physical writes non checkpoint

8

Number of times a buffer is written for reasons other than advancement of the checkpoint. Used as a metric for determining the I/O overhead imposed by setting the FAST_START_IO_TARGET parameter to limit recovery I/Os. (Note that FAST_START_IO_TARGET is a deprecated parameter.) Essentially this statistic measures the number of writes that would have occurred had there been no checkpointing. Subtracting this value from "physical writes" gives the extra I/O for checkpointing.

pinned buffers inspected

8

Number of times a user process, when scanning the tail of the replacement list looking for a buffer to reuse, encountered a cold buffer that was pinned or had a waiter that was about to pin it. This occurrence is uncommon, because a cold buffer should not be pinned very often.

Number of redo blocks that were checksummed by the LGWR.

redo blocks written

2

Total number of redo blocks written. This statistic divided by "redo writes" equals number of blocks per write.

redo buffer allocation retries

2

Total number of retries necessary to allocate space in the redo buffer. Retries are needed either because the redo writer has fallen behind or because an event such as a log switch is occurring.

redo entries

2

Number of times a redo entry is copied into the redo log buffer

redo entries for lost write detection

2

Number of times a Block Read Record is copied into the log buffer.

redo log space requests

2

Number of times the active log file is full and Oracle must wait for disk space to be allocated for the redo log entries. Such space is created by performing a log switch.

Log files that are small in relation to the size of the SGA or the commit rate of the work load can cause problems. When the log switch occurs, Oracle must ensure that all committed dirty buffers are written to disk before switching to a new log file. If you have a large SGA full of dirty buffers and small redo log files, a log switch must wait for DBWR to write dirty buffers to disk before continuing.

Also examine the log file space and log file space switch wait events in V$SESSION_WAIT

table fetch by rowid

64

Number of rows that are fetched using a ROWID (usually recovered from an index)

This occurrence of table scans usually indicates either non-optimal queries or tables without indexes. Therefore, this statistic should increase as you optimize queries and provide indexes in the application.

table fetch continued row

64

Number of times a chained or migrated row is encountered during a fetch

Retrieving rows that span more than one block increases the logical I/O by a factor that corresponds to the number of blocks than need to be accessed. Exporting and re-importing may eliminate this problem. Evaluate the settings for the storage parameters PCTFREE and PCTUSED. This problem cannot be fixed if rows are larger than database blocks (for example, if the LONG datatype is used and the rows are extremely large).

table scan blocks gotten

64

During scanning operations, each row is retrieved sequentially by Oracle. This statistic counts the number of blocks encountered during the scan.

This statistic tells you the number of database blocks that you had to get from the buffer cache for the purpose of scanning. Compare this value with the value of "consistent gets" to determine how much of the consistent read activity can be attributed to scanning.

Database and ASM instances

ASnn

Logical Standby / Streams Apply Process Reader Server or Apply Server

- Computes dependencies between logical change records (LCRs) and assembles messages into transactions (Reader Server)

- Applies LCRs to database objects or passes LCRs and user messages to their appropriate apply handlers (Apply Server)

When the reader server finishes computing dependencies between LCRs and assembling transactions, it returns the assembled transactions to the coordinator process. Query V$STREAMS_APPLY_READER for information about the reader server background process.

An apply server receives the transactions from the coordinator background process, and either applies database changes in LCRs or sends LCRs or messages to apply handlers. Apply servers can also enqueue a queue. If an apply server encounters an error, then it then tries to resolve the error with a user-specified conflict handler or error handler. If an apply server cannot resolve an error, then it rolls back the transaction and places the entire transaction, including all of its messages, in the error queue. When an apply server commits a completed transaction, this transaction has been applied. When an apply server places a transaction in the error queue and commits, this transaction also has been applied. Query V$STREAMS_APPLY_SERVER for information about the apply server background process.

The coordinator process name is ASnn, where nn can include letters and numbers.

Database instance

DBWn

Database Writer Process

Writes modified blocks from the database buffer cache to the data files

The primary responsibility of DBWn is to write data blocks to disk. DBWn also handles checkpoints, file open synchronization, and logging of Block Written records.

In many cases the blocks that DBWn writes are scattered throughout the disk. Thus, the writes tend to be slower than the sequential writes performed by LGWR. DBWn performs multiblock writes when possible to improve efficiency. The number of blocks written in a multiblock write varies by operating system.

The DB_WRITER_PROCESSES initialization parameter specifies the number of DBWn processes (DBW0-DBW9 and DBWa-DBWz). The database selects an appropriate default setting for this parameter or adjusts a user-specified setting based on the number of CPUs and processor groups.

When you start the Data Guard broker, a DMON process is created. DMON runs for every database instance that is managed by the broker. DMON interacts with the local database and the DMON processes of the other databases to perform the requested function. DMON also monitors the health of the broker configuration and ensures that every database has a consistent description of the configuration.

DMON maintains profiles about all database objects in the broker configuration in a binary configuration file. A copy of this file is maintained by the DMON process for each of the databases that belong to the broker configuration. The process is created when the DG_BROKER_START initialization parameter is set to true.

Dnnn

Dispatcher Process

Performs network communication in the shared server architecture

In the shared server architecture, clients connect to a dispatcher process, which creates a virtual circuit for each connection. When the client sends data to the server, the dispatcher receives the data into the virtual circuit and places the active circuit on the common queue to be picked up by an idle shared server. The shared server then reads the data from the virtual circuit and performs the database work necessary to complete the request. When the shared server must send data to the client, the server writes the data back into the virtual circuit and the dispatcher sends the data to the client. After the shared server completes the client request, the server releases the virtual circuit back to the dispatcher and is free to handle other clients.

Several initialization parameters relate to shared servers. The principal parameters are: DISPATCHERS, SHARED_SERVERS, MAX_SHARED_SERVERS, LOCAL_LISTENER, REMOTE_LISTENER.

Pnnn

Parallel Query Slave Process

Perform parallel execution of a SQL statement (query, DML, or DDL)

Parallel Query has two components: a foreground process that acts as query coordinator and a set of parallel slaves (Pnnn) that are background processes. These background processes are spawned or reused during the start of a parallel statement. They receive and carry out units of work sent from the query coordinator.

The maximum number of Pnnn processes is controlled by the initialization parameter PARALLEL_MAX_SERVERS. Slave processes are numbered from 0 to the PARALLEL_MAX_SERVERS setting. If the query is a GV$ query, then these background processes are numbered backward, starting from PZ99.

RPnn

Capture Processing Worker Process

Processes a set of workload capture files

RPnn are worker processes spawned by calling DBMS_WORKLOAD_REPLAY.PROCESS_CAPTURE(capture_dir,parallel_level). Each worker process is assigned a set of workload capture files to process.

Worker processes execute in parallel without needing to communicate with each other. After each process is finished processing its assigned files, it exits and informs its parent process.

The number of worker processes is controlled by the parallel_level parameter of DBMS_WORKLOAD_REPLAY.PROCESS_CAPTURE. By default, parallel_level is null. Then, the number of worker processes is computed as follows:

SELECT VALUE
FROM   V$PARAMETER
WHERE  NAME='cpu_count';

When parallel_level is 1, no worker processes are spawned.

Database instance

SMON

System Monitor Process

Performs critical tasks such as instance recovery and dead transaction recovery, and maintenance tasks such as temporary space reclamation, data dictionary cleanup, and undo tablespace management

SMON performs many database maintenance tasks, including the following:

- Creates and manages the temporary tablespace metadata

- Reclaims space used by orphaned temporary segments

- Maintains the undo tablespace by onlining, offlining, and shrinking the undo segments based on undo space usage statistics

- Cleans up the data dictionary when it is in a transient and inconsistent state

- Maintains the SCN to time mapping table used to support Oracle Flashback features

In an Oracle RAC database, the SMON process of one instance can perform instance recovery for other instances that have failed.

SMON is resilient to internal and external errors raised during background activities.

Snnn

Shared Server Process

Handles client requests in the shared server architecture

In the shared server architecture, clients connect to a dispatcher process, which creates a virtual circuit for each connection. When the client sends data to the server, the dispatcher receives the data into the virtual circuit and places the active circuit on the common queue to be picked up by an idle shared server. The shared server then reads the data from the virtual circuit and performs the database work necessary to complete the request. When the shared server must send data to the client, the server writes the data back into the virtual circuit and the dispatcher sends the data to the client. After the shared server completes the client request, the server releases the virtual circuit back to the dispatcher and is free to handle other clients.

Several initialization parameters relate to shared servers. The principal parameters are: DISPATCHERS, SHARED_SERVERS, MAX_SHARED_SERVERS, LOCAL_LISTENER, REMOTE_LISTENER.
