rman 使用catalog备份的演示

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

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

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> register 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-03002: failure of list command at 06/19/2013 15:15:22

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

---------- ---------- ---------- -------- ----------------- ---------

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

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
