As a follow-on from my 10g RAC on NFS article, I thought it would be nice to have an 11g RAC on NFS article. The process is very similar, with a couple of exceptions:
- The Virtual IP Configuration Assistant (vipca) runs in silent mode without any problems now. Under 10g, you had to use a “real” public IP address for this to work. Under 11g it now works with private IPs like “192.168.x.x” etc.
- Oracle 11g includes a Direct NFS Client for “optimized” Oracle over NFS performance. I don’t have the relevant kit to do a performance comparison, so I don’t know if it’s worth it or not. If someone has some figures for this I would be interested to hear them.
Cheers
Tim…
Update: For information on Direct NFS Client performance look here.

Could DBMS_RESOURCE_MANAGER.CALIBRATE_IO() (New 11g function) be used to do a performance comparision?

Hi.
It certainly could. In my case it wasn’t so much a problem of how, it was that I’m running this on really ropey kit, so any performance comparison is flawed to say the least.
