We have several DB's running as single instance but we also have  a lot of RAC Clusters.
Both installations are based on Linux. The experience we got with oracle on netapp is quite good, but with our RAC's we didn't make the best experiences.
Backing up Oracle DB's on NFS with snapshot technology is very handsome. As mentioned recovering a full DB under a minute is nearly unbeatable.
We use self written scripts to backup DB's and their archive logs.
 
What are your experiences with rac clusters over gigabit nfs? What kind of filers do you use?
I would be interested in some details of you environement with Oracle RAC on Linux and NetApp.
Today we are in discussion of response times and throughput rates. I would like to share some experiences.
 
Regards
Andreas

We have over 30 oracle database instances running on both linux and solaris over gigabit nfs.  Some are standalone and others raq clusters.  There is a product from netapp called snapmanager for oracle but we currently do not use it, instead we just utilize scripts that either put the instance in hot backup mode or brings the db down for cold backup and then initiates a snapshot on the filer.  We snapvault the primary snapshot data to a secondary R200 as well.

This scenario works flawlessly and anything from single file restores to entire volume restores take seconds and always work.  There was a bit of hesitation implementing this at first but the first time you recover a database completely in under a minute your DBA's will be on board.

Looking for someone out there with some experience with pSeries +
Oracle. Is SnapVault, SnapMirror, Snapshot used as common replication
tools for Oracle in the General Public versus native Oracle Replication
or Snapshots? Long ago we also looked at Native clustering / replication
tools at the P-Series level. Just curious on how many companies use the
SAN replication tools for Oracle. I'd appreciate any insight you might
have and I'll try and do some research on this.

From a storage admin side I was assuming it's as simple as creating a
shell script that quiesces Oracle, takes a snapshot and then lets Oracle
move on with it's life, am I missing something?
