I'm not sure what OIA is but you can backup Oracle RAC using Oracle RMAN in 
tandem with the NetBackup Oracle agent.   With RMAN you don't have to take the 
database online.   Our DBAs here set their backup to the node but I've 
suggested more than once that they use the VIP instead because that will float 
to another node if the one they're backing up would go down.

I don't think you'd be able to ever backup from multiple nodes at the same time 
for the same RAC cluster since each node is mounting the SAME disks as the 
other nodes in that cluster.

For larger databases we do disk array copying (e.g. EMC BCV or SRDF or Hitachi 
Shadow Images) to mirror each disk (or LUN) from the Production server to other 
disks (or LUNs) within the array.   When that is fully synchronized we put 
Oracle into  hot backup (or shut it down completely once a week for "cold" 
backup), split the mirror off, take Oracle out of hot backup (or restart it) on 
Production.   We then mount the mirror copy on a separate media server and do  
standard (i.e. flat file, not Oracle/RMAN) backup.   Most of the shops I've 
worked in did this.

One place I worked instead setup separate servers that had a cloned database 
mounted in standby mode.   We had full redo logging turned on and copied 
Production logs from there to the standby node then applied the logs to that 
standby database.   That meant you could get Production back online by taking 
the standby out of standby and making it the Production node.   (We did 
however, put in a 6 hour delay between shipping the logs to the standby server 
and actually applying them to help prevent any faux pas that took down 
Production from getting immediately applied to standby.)

Subject: [Veritas-bu] NetBackup Oracle Intelegent Agent

We have NetBackup 7.6.0.4 running on Red Hat Linux 6.6 as our master server 
with a requirement to backup a number of Oracle 12c Databases (also running on 
RHEL 6.6) using the new Symantec OIA product. The databases are all RAC 
clusters, which the agent cannot cope with, so we are backing each database up 
as a single node.

Does anybody have any experience of this and if so were any issues encountered.
