I´d start checking if both disks can be seen from all nodes.

Comment on Storing Oracle database connection strings in OpenLDAP instead of OID by fs111 (@fs111)

Thanks a ton for this guide! This solved a problem I was having, where I was moving a legacy app to the amazon cloud and I needed to store the oracle connections somewhere without going crazy.

You should add a flattr button to your blog, I would totally click it. :-) Keep up the good work!

I also have problems while installing on 2 VMware nodes, eachone is running on a different vmware server.

It seems that there is an issue during installation with the hdd on node 2

on each node there is a online Raw disk with 15GB, they have both the same location (bus and id), what have i done wrong?

Comment on ext4 file systems and the 16 TB limit – how to solve it by Roman

Doesn’t seem like the lates git pull tune2fs will let you set -O 64bit on an existing FS.

“Setting filesystem feature ’64bit’ not supported.”

There seems to be a patch in there to allow resize2fs to go beyond 16TB, but it won’t do it @ 32 bit, and yet you can’t modify it to 64bit with tune.

I had a similar problem (unable to configure grid infrastructure) and it was a simple fix. The setup:
Windows 2008R2 running on Hyper-V
Oracle 11.2.0.3 grid infrastructure single instance setup

The error messages in the install log indicated that my user did not have administrative privileges. The privilege was granted through a group. I added my domain user directly to the Administrators group on the server and I was able to successfully configure Grid & ASM.

HTH!

Comment on MEMORY_TARGET (SGA_TARGET) or HugePages – which to choose? by Ronny Egner

Ronny Egner — Sun, 20 Nov 2011 12:32:41 +0000

Looks good from what i can tell. Maybe you have some kind of wild running user process using a lot of memory. Huge Pages are by default not swappable.

Regadring the process which did not start: This might be a side effect of a heavy loaded system.

My recommendation is to monitor the system using OSWatcher and look at the memory indicators.

One further question: Did you reboot the system to allocate the huge pages? Allocating them on a system which was running for some time might also cause heavy swapping.

I implemeted huge pages on linux and start getting error:-
1)I am getting ORA-00445: background process “J000″ did not start after 120 seconds
kkjcre1p: unable to spawn jobq slave process
I’m running 2 oracle 11.2 databases on SUSE Linux Enterprise Server (SLES) having total 16 gb physical
memory.
1) sga_target 6gb sga_max_size =8g
2) sga_target=sga_max_size=1536 mb
I configured huges pages and
I run hugepages_settings.sh as per the document
Document 401749.1 and it s giving
Recommended setting: vm.nr_hugepages = 4868
which is looking wrong to me.
and also getting following message via OEM
