I. How to Create an RMAN Recovery Catalog Database

Create the rman user that will be the owner of the rman catalog, on the catalog database. The catalog database is usually a small database it contains and maintains the metadata of all rman backups performed using the catalog.

Step 0: Environment

Target Database: w148p, Version: 11.2.0.3.0
Catalog Database: cat, Version: 11.2.0.3.0 , catalog user: rman

Step 1: Create user and grant privs

SQL> select name,open_mode from v$database;

NAME      OPEN_MODE
--------- --------------------
CAT       READ WRITE

SQL> CREATE USER rman IDENTIFIED BY cat
TEMPORARY TABLESPACE temp
DEFAULT TABLESPACE users
QUOTA UNLIMITED ON users;  2    3    4

User created.

SQL> GRANT RECOVERY_CATALOG_OWNER TO rman;

Grant succeeded.

SQL>

Step 2: Create Recovery Catalog

[oracle@rac2 ~]$ . oraenv
ORACLE_SID = [cata] ? cat
The Oracle base has been set to /u01/app/oracle

[oracle@rac2 ~]$ rman catalog rman/cat

connected to recovery catalog database

RMAN> create catalog;

recovery catalog created

RMAN> exit


Recovery Manager complete.
[oracle@rac2 ~]$

Step 3: Register catalog database with target database

[oracle@rac2 ~]$ rman target sys/sys@w148p catalog rman/cat@cat

Recovery Manager: Release 11.2.0.3.0 - Production on Wed Jul 20 12:48:12 2016

connected to recovery catalog database

RMAN> REGISTER DATABASE;

database registered in recovery catalog

Step 4: Verify registration

[oracle@rac2 ~]$ rman target sys/sys@w148p catalog rman/cat@cat

II. How to do manual-backup-registration

Manual backups, made using Rman without a recovery catalog, can be cataloged and made available to the rman catalog.In this example a controlfile backup is made using rman in NOCATALOG mode, afterwards the backup is catalogued.

Step 1: Simulate the issue:

[oracle@rac2 ~]$ rman TARGET sys/sys@w148p NOCATALOG

Step 2: Verify

III. How to export the Catalog

The database holding the rman catalog should be protected against information loss, the minimum level of protection can be implemented by executing a full export of the catalog schema. In case of catalog loss an import of the schema on a new or existing database will make the catalog available again.

[oracle@rac2 ~]$ expdp \" / as sysdba\"  directory=DATA_PUMP_DIR schemas=rman dumpfile=rman_schemas.dmp logfile=rman_schemas.log

VI.Unregister database from catalog db

If a database is not longer required on the rman catalog it can be unregistered.Note that rman metadata is always stored also on the local controlfile, if a database is unregistered from the catalog, it can be afterwards registered again and all backups contained in the controlfile will be cataloged

[oracle@rac2 ~]$ rman target sys/sys@w148p catalog rman/cat@cat
