|Component||Release Number Refers to ...|
|RMAN client||Version of RMAN client (displayed when you start RMAN)|
|Recovery catalog database||Version of Oracle database|
|Recovery catalog schema in recovery catalog database||Version of RMAN client used to create the recovery catalog|
|Target database||Version of Oracle database|
|Auxiliary database||Version of Oracle database|
For example, you can use a release 9.0.1 RMAN client with:
A release 9.0.1 target database
A release 9.0.1 duplicate database
A release 8.1.7 recovery catalog database whose catalog tables were created with RMAN release 9.0.1
To determine the current release of the catalog schema, you must run a SQL query.
Use SQL*Plus to connect to the recovery catalog database as the catalog owner. For example, enter:
% sqlplus rman/rman@catdb
rcver catalog table. For example, run this query:
SQL> SELECT * FROM rcver; VERSION ------------ 08.01.05.00 09.00.01.00 10.02.01.00
If multiple versions are listed, then the last row is the current version, and the rows before it are prior versions. In the preceding example, the current catalog schema version is 09.00.01.00 and the previous version was 08.01.05.00.
Note that for releases 10.2 and later, the last two digits indicate patch level. For earlier releases, they are always zeros.
