Less know features: Alternate Archive Log Destination

October 5th, 2010 No comments

Oracle offers the ability to specify so called ‘alternative’ archive log destinations in case the primary archive log destination gets full. You can enable this feature by setting:

log_archive_dest_1='location=+FRA REOPEN=0 MANDATORY alternate=log_archive_dest_2'
log_archive_dest_2='location=/some_path MANDATORY'

A configuration often used involved using the flash recovery area as primary destination and a nfs destination as alternative archive log destination.
