Cause:  trying you register the standby database to perform/configure backup?

OPEN_MODE CONTROL

MOUNTED      STANDBY


Solution:

If yes then register the primary database instead of a standby database. Once you register the primary database, you can use the same catalog schema for the backup of physical standby database since the DBID of both the databases is same.
