Netbackup rman script for multiple instances on same host

Hi All,

We are doing oracle agent based backups and to backup multiple Oracle instances on a same host we have to create a seperate script for each

instance and a seperate policy for each instance. 

Is it possible if we can backup all Oracle instances using one policy and this can be achieved from one RMAN script ...?

As in the rman script we mention only one Oracle SID , if somehow we can mention multiple SID.

Please if you can suggest a solution /workaround for this as creating new policy for each instance will increase the number of policies.

Regards,

Abhishek
