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
Copyright (c) 1982, 2005, Oracle. All rights reserved.
RMAN> list backup;
using target database control file instead of recovery catalog
