介绍了如何使用catalog方式做RMAN备份，以及如何取消以catalog方式做备份。
第一步：创建RMAN CATALOG表空间及用户。
[oracle@oel-01 ~]$ sqlplus / as sysdba
SQL> create tablespace catalog1 datafile '/u01/app/oracle/oradata/bys001/catalog1.dbf' size 50m ;
Tablespace created.
SQL> create user rmanuser identified by rmanuser default tablespace catalog1;
User created.
SQL> grant connect,resource,recovery_catalog_owner to rmanuser;
Grant succeeded.
SQL> select * from role_sys_privs where role='RECOVERY_CATALOG_OWNER';
ROLE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
RECOVERY_CATALOG_OWNER CREATE SYNONYM NO
RECOVERY_CATALOG_OWNER CREATE CLUSTER NO
RECOVERY_CATALOG_OWNER ALTER SESSION NO
RECOVERY_CATALOG_OWNER CREATE DATABASE LINK NO
RECOVERY_CATALOG_OWNER CREATE SESSION NO
RECOVERY_CATALOG_OWNER CREATE TABLE NO
RECOVERY_CATALOG_OWNER CREATE SEQUENCE NO
RECOVERY_CATALOG_OWNER CREATE PROCEDURE NO
RECOVERY_CATALOG_OWNER CREATE VIEW NO
RECOVERY_CATALOG_OWNER CREATE TYPE NO
RECOVERY_CATALOG_OWNER CREATE TRIGGER NO
11 rows selected.
第二步：注册数据库到RMAN CATALOG
[oracle@oel-01 ~]$ rman target
sys/sys@192.168.1.212:1521/bys001 catalog rmanuser/rmanuser
Recovery Manager: Release 11.2.0.1.0 - Production on Wed Jun 19 14:28:59 2013

connected to recovery catalog database
RMAN>
register database;
database registered in recovery catalog
starting full resync of recovery catalog
full resync complete
第三步：查看是否注册
SQL> conn rmanuser/rmanuser
Connected.
SQL> select * from rc_database;
DB_KEY DBINC_KEY DBID NAME RESETLOGS_CHANGE# RESETLOGS
---------- ---------- ---------- -------- ----------------- ---------
2 4 2041679290 BYS001 1143629 16-JUN-13
第四步：到RMAN中执行全备备份
[oracle@oel-01 ~]$ rman target
sys/sys@192.168.1.212:1521/bys001
catalog rmanuser/rmanuser

RMAN> backup database;

第五步：取消使用CATALOG备份
这是使用list backup 查出来的信息，信息太多，只截了此次使用CATALOG备份的两个备份集。

RMAN> unregister database; 取消当前登陆的数据库注册到catalog
database name is "BYS001" and DBID is 2041679290
Do you really want to unregister the database (enter YES or NO)? y
database unregistered from the recovery catalog
RMAN> list backup;
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

RMAN-06004: ORACLE error from recovery catalog database: RMAN-20001: target database not found in recovery catalog
RMAN> exit
Recovery Manager complete.
报错是因为登陆时是以指定catalog方式登陆，退出重新查询就可以了。
在SQLPLUS中查询
SQL> conn rmanuser/rmanuser
Connected.
SQL> select * from rc_database;
DB_KEY DBINC_KEY DBID NAME RESETLOGS_CHANGE# RESETLOGS
---------- ---------- ---------- -------- ----------------- ---------
2 4 2041679290 BYS001 1143629 16-JUN-13
SQL> select * from rc_database;
no rows selected
第六步：重新登陆RMAN查看备份集信息：
[oracle@oel-01 ~]$ rman target /
Recovery Manager: Release 11.2.0.1.0 - Production on Wed Jun 19 15:15:48 2013

connected to target database: BYS001 (DBID=2041679290)
RMAN> list backup;
