Ao logar em um catálogo do RMAN para registrar um novo banco de dados no catálogo, a seguinte mensagem é retornada:

PL/SQL package RMAN.DBMS_BA version 12.02.00.01.0 in RCVCAT database is too old

A correção é simples, basta fazer o upgrade do catálogo em 2 passos:

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

E incluir o mesmo comando novamente para confirmar o upgrade:

RMAN> UPGRADE CATALOG;

recovery catalog upgraded to version 12.02.00.01
DBMS_RCVMAN package upgraded to version 12.02.00.01
DBMS_RCVCAT package upgraded to version 12.02.00.01.

RMAN>

Após fazer o upgrade, basta continuar a operação:

[oracle@serverprod ~]$ rman target / catalog rman@anvsrepository
