RMAN-06429: TARGET database is not compatible with this version of RMAN

In general, the rules of RMAN compatibility are as follows:

The RMAN catalog schema version should be greater than or equal to the catalog database version.
The RMAN catalog is backwards compatible with target databases from earlier releases.
The versions of the RMAN executable and the target database should be the same.

MY DB:

SQL> select * from rcver;

VERSION
------------
10.02.00.0

BD TARGET:

Oracle Database 11g Release 11.2.0.1.0 - 64bit Production


You can upgrade the catalog schema ,do the following:

1. Connect to target and catalog using the 11.2.0.1 RMAN executable.
2. Run this command two times: RMAN> upgrade catalog;
3. Run the RMAN duplication again.


RMAN> upgrade catalog;

recovery catalog owner is RMAN
enter UPGRADE CATALOG command again to confirm catalog upgrade

RMAN> upgrade catalog;
recovery catalog upgraded to version 11.02.00.01
DBMS_RCVMAN package upgraded to version 11.02.00.01
