Haven’t done it with VCS (we do RAC on Linux which uses Oracle Clusterware).  

 

As noted below the DB seen on each node is actually the same DB so you only need to back it up once.

 

I’d recommend setting up RMAN to backup via RAC’s virtual IP rather than either node’s physical IP.   Although it is one DB there is a separate instance on each node and a virtual IP associated with each of those.  On failure of a node the virtual IP for that node fails over to one of the other running nodes.  If you’re backups rely on the virtual IP you won’t have to do any adjustment for a failure of a physical node.

You back up a database, not a cluster, and the one RAC database is on two servers.  You only need to have one media server and you can run the backups through that one server.

 

If you intend to have more than one media server, you'd have to figure a way to divide the database tables of the single instance across two servers and the admin of that would probably be too much hassle.  If you've got one instance on two server, just ignore the other server for backup purposes.

 

My $.02, at least.

Subject: [Veritas-bu] configure nodes of VCS Oracle Rac cluster as mediaservers

Hi, I am configuring a 2 node VCS cluster for backup and i would like to know the recommendations for doing this. Both nodes will have access to a virtual tape library which is san connected. The cluster is running Oracle RAC.

 

I have installed the media server software on each node of the cluster and used the physical node name during the install. I want to back up each node directly to the virtual tape library.

 

DO i need to run the cluster_config script? I do not necessarily want Veritas to manage media server failover between the nodes as this is an active/active cluster.

 

Should i configure each node of the cluster as though it were an independent SAN media server?

 

Thanks for any advice!
