Recovery catalog for RMAN
Creating the Recovery Catalog Owner
Start by creating a database schema (usually called rman). Assign an appropriate tablespace to it and grant
it the recovery_catalog_owner role. Look at this example:
% sqlplus '/ as sysdba'
SQL> CREATE USER rman IDENTIFIED BY rman
DEFAULT TABLESPACE tools
TEMPORARY TABLESPACE temp
QUOTA UNLIMITED ON tools;
SQL> GRANT CONNECT, RECOVERY_CATALOG_OWNER TO rman
Creating the Recovery Catalog
% rman catalog rman/rman@ORCL
RMAN> CREATE CATALOG;
Registering the target database
% rman TARGET / CATALOG rman/rman@ORCL
RMAN> REGISTER DATABASE;
