Database Software

Hi:

Have 2 node RAC. My Shared storage is on openfiler.

Oracle 11g Grid was successfully installed and all the services was working fine. When i restarted the system I found CRS was not coming up. Remaining processes were up and running.

Let me explain what I did: (O/s RHEL 5.4 & oracle 11g R2 grid)

I have a partition in shared disk /dev/sdc1 (I have other partitions, but thought of using only one for OCR and voting disk). (did not define it as raw partition as I used to do in 10g RAC).

While installing Oracle grid and when it prompted to enter the Diskgroup for OCR and Voting disk I gave a name DGDATA and choose only one (external redundancy) disk “/dev/sdc1″ (it does not ask for one for OCR and one for Voting as it used to do in 10g clusterware installation). As per my assumption both OCR and Voting disk were created within /dev/sdc1 (after installation when I queried I got the same info)

The Oracle grid installation has gone through successfully. when I restart the system I find CRS not starting.

The log says: “Error PROC:26: Error while accessing the physical storage ASM……..
ORA-01034: oracle not available...
Could not init OCR, code:26….
Linux permission denied".

For your information….ASM instance is up (check in both the nodes) and I find the diskgroup mounted.

Can anyone help on this.

Also let me know how to uninstall Oracle 11g Grid software and configuration. If I have to reinstall the Oracle 11g grid software and config once again is it possible without reinstalling RHEL. Let me know the steps or any link please. don't want to get into a mess again.

Thanks in advance.
