Oracle Error Message
RMAN-06441: cannot upgrade catalog – catalog is already newer than this RMAN
Reason for the Error
The recovery catalog is already at a version level that is greater than this version of the Recovery Manager. The UPGRADE CATALOG command is not needed.
Solution
Either upgrade to a more recent Recovery Manager, or continue to use the current version. Message 6191 will be issued if the recovery catalog is too new to work with this version of Recovery Manager.
