RMAN-在恢复目录中注册和取消数据库

创建恢复目录
1、在目录数据库中创建恢复目录所用表空间
SQL> create tablespace rman_ts datafile 'c:\oracle\oradata\cc\rmants.ora' size 20M ;
表空间已创建。

2、在目录数据库中创建RMAN 用户并授权
SQL> create user rman identified by rman default tablespace rman_ts temporary tablespace temp
quota unlimited on rmants;
用户已创建

SQL> grant recovery_catalog_owner,resource to rman;

Grant succeeded.

3、在目录数据库中创建恢复目录
[oracle@node1 ~]$ rman catalog  rman/rman@ping

Recovery Manager: Release 10.2.0.1.0 - Production on Wed Jan 7 09:52:13 2009

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

connected to recovery catalog database

RMAN> create catalog tablespace rman_ts;

recovery catalog created

4、注册目标数据库到恢复目录
目标数据库:racdb
恢复目录：ping

[oracle@node1 ~]$ rman target  sys/1@racdb

Recovery Manager: Release 10.2.0.1.0 - Production on Wed Jan 7 10:05:50 2009

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

connected to target database: RACDB (DBID=672464192)

RMAN> connect catalog  rman/rman@ping

connected to recovery catalog database

RMAN> register database;

database registered in recovery catalog
starting full resync of recovery catalog
full resync complete

二、取消数据库的注册
1．在SQLPLUS使用RMAN用户登录恢复目录

[oracle@node1 ~]$ sqlplus /nolog

SQL*Plus: Release 10.2.0.1.0 - Production on Wed Jan 7 10:50:06 2009

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

SQL> conn  rman/rman@ping 
Connected.

2．查找表DB 中的注册记录
[oracle@node1 ~]$ rman target  sys/1@racdb

Recovery Manager: Release 10.2.0.1.0 - Production on Wed Jan 7 10:49:03 2009

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

connected to target database: RACDB (DBID=672464192)

RMAN>

SQL> select db_key,db_id from db;

    DB_KEY      DB_ID
---------- ----------
         1  672464192

DBID=DB.DB_ID
## 切记一定要使用RMAN的用户登陆，不然将出现如下错误提示

SQL> conn  sys/sys@ping as sysdba
Connected.
SQL> select db_key,db_id from db;
select db_key,db_id from db
                         *
ERROR at line 1:
ORA-00942: table or view does not exist

3．注销数据库
SQL> execute dbms_rcvcat.unregisterdatabase(1,672464192);

PL/SQL procedure successfully completed.

4．验证注销动作
[oracle@node1 ~]$ rman

Recovery Manager: Release 10.2.0.1.0 - Production on Wed Jan 7 11:02:16 2009

RMAN> list backup;

using target database control file instead of recovery catalog
