介紹了如何使用catalog方式做RMAN備份，以及如何取消以catalog方式做備份。

第一步：創建RMAN CATALOG表空間及用戶。

[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：注冊數據庫到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 target database: BYS001 (DBID=2041679290)
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：查看是否注冊

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中執行全備備份

[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
Copyright (c) 1982, 2009, Oracle and/or its affiliates.??All rights reserved.
connected to target database: BYS001 (DBID=2041679290)
connected to recovery catalog database
RMAN> register database;
database registered in recovery catalog
starting full resync of recovery catalog
full resync complete
RMAN> backup database;

channel ORA_DISK_1: backup set complete, elapsed time: 00:12:38

piece handle=/backup/ctl_c-2041679290-20130619-08 comment=NONE
Finished Control File and SPFILE Autobackup at 19-JUN-13

第五步：取消使用CATALOG備份

這是使用list backup 查出來的信息，信息太多，只截了此次使用CATALOG備份的兩個備份集。

RMAN> unregister database;? ?? ?取消當前登陸的數據庫注冊到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> exit

Recovery Manager complete.
報錯是因為登陸時是以指定catalog方式登陸，退出重新查詢就可以了。

在SQLPLUS中查詢
SQL> conn rmanuser/rmanuser
Connected.
SQL> select * from rc_database;
? ? DB_KEY??DBINC_KEY? ?? ? DBID NAME? ???RESETLOGS_CHANGE# RESETLOGS
---------- ---------- ---------- -------- ----------------- ---------

SQL> select * from rc_database;
no rows selected

第六步：重新登陸RMAN查看備份集信息：

[oracle@oel-01 ~]$ rman target /
Recovery Manager: Release 11.2.0.1.0 - Production on Wed Jun 19 15:15:48 2013
Copyright (c) 1982, 2009, Oracle and/or its affiliates.??All rights reserved.
connected to target database: BYS001 (DBID=2041679290)
RMAN> list backup;
using target database control file instead of recovery catalog
List of Backup Sets
