This issue has been solved. See solution.

Hi All,

 

Needs some feedback on this configuration's support/compatibility as a netbackup client with the oracle agent.

 

NBU 6.5.x

AIX 5.3 TL 11

Oracle 10g RAC

GPFS 3.2.0.29

 

Can I back it up using RMAN (via oracle agent) or is the FS a delimiting factor?

Looking at the DB agent support list (http://www.symantec.com/business/support/index?page=content&id=TECH43684) it suggests support for Oracle 10g (and R2) on AIX 5.3.

The file system is not of importance as NBU will not interact with the file system directly, unless you try snapshot backups. And GPFS/NBU combination is not supported as far as I know when doing snapshots...

So if RMAN can pull a decent I/O rate, you should be good to go.

GPFS is a funny file system, as it is fairly decent to serve few, but very large files, whereas it definately comes short when you have many files of mainly small files. The concurrency checking for access  is the problem I guess. For Oracle, I imagine you would see acceptable performance.

I have a GPFS file system with 100+ million files, we get ~2.3MB/s using standard policy... :-(

Thanks for the clarification!

You need an OpenVision to see the truth about Backups. Restores are a plus. But that's just Semantics ;)

ITs easy :)
