Oracle RMAN Interview Question:

How to identify what are the all the target databases that are being backed-up with RMAN database?

Submitted by: Administrator

You only can get information about one particular database at a time, after connecting with RMAN using target as that particular database.
Suppose there are three db A,B,C.

RMAN> connect target userA/pwd

Now whatever query you will execute will only give information about that database A only.
