RMAN 11g/12c Client compatibility

Posted on

Question :

I’m having a Recovery catalog database 12c version. While I’m trying to register the target database (11g) with the catalog I get the following error:

Recovery Manager: Release - Production on Fri Aug 14 13:03:44 2015

RMAN-06618: RMAN client and database release mismatch; indicated database release is

I have checked the compatibility matrix, it says the RMAN client and the target database has to be the same version. But I’m using Catalog as 12c database therefore the client is 12 as well. Should I use RMAN 11g client to connect to the target? If yes, How should I do that?

Answer :

As per compatibility matrix, the target and the RMAN client version has to be the same. The workaround is connect to the catalog database from the target database ( whose version is lower than that of the RMAN client) and register the database in the catalog.


You must use the RMAN executable that is in the classpath that is used to run (or how would you say that) your database. That is the one from 11g. Just do . oraenv <database> (note space between . and oraenv) to set the correct path and then execute rman.
