Recent Changes

The target database has been recently upgrade to 11.2.0.3 and so RMAN executable is upgraded but catalog database is not aware of this upgrade.

Cause of the Problem
The problem happened due to version mismatch between the RMAN-executable and the RMAN-catalog SCHEMA.

Solution of the Problem
Solution 01:
Upgrade the RMAN catalog SCHEMA. Start the RMAN-executable from the ORACLE_HOME which has been upgraded. There is only a connection to the CATALOG required.
A connection to the TARGET is optional.

For example issue,

$ rman catalog $RMAN_USERID/$RMAN_PASSWD@$RMAN_CONN_STR
RMAN> upgrade catalog;

Solution 02:
Don't use catalog for backup information. So run backup without connecting catalog database.

$ rman target /
$ backup database;
