（RMAN）使用恢复目录数据库执行RMAN步骤 推荐

我想建立一个RMAN备份机制，本机为目标数据库，sid为orcl10的数据库为恢复目录来做备份，但总不成功，以下是我的执行步骤：
SQL> conn sys/e2000jl@orcl10 as sysdba
Connected.
SQL> create user rman
2 identified by rman123;
User created.
SQL> grant dba to rman;
Grant succeeded.

C:\Documents and Settings\zouyang>rman target sys/system catalog rman/rman123@orcl10
Recovery Manager: Release 10.1.0.2.0 - Production
Copyright (c) 1995, 2004, Oracle. All rights reserved.
connected to target database: ORCL (DBID=1227672490)
connected to recovery catalog database
recovery catalog is not installed

RMAN> show channel for device type disk;
recovery catalog is not installed
recovery catalog is not installed
RMAN-00571: ===============================================
RMAN-00569: =========ERROR MESSAGE STACK FOLLOWS ========
RMAN-00571: ===============================================

可以连接上恢复目录数据库，但是无法使用这个恢复目录，Oracle报错“recovery catalog is not installed”。

在网上搜了下，重新建立步骤如下：
第一步：Create Recovery Catalog
First create a user to hold the recovery catalog:
-- Create tablepsace to hold repository
SQL> create tablespace rman_tools
2 datafile
3 'D:\ORACLE\PRODUCT\10.1.0\ORADATA\ORCL10\rman01.dbf'
4 size 100m;
Tablespace created
-- Create rman schema owner
SQL> create user rman
2 identified by rman123
3 default tablespace rman_tools
4 quota unlimited on rman_tools;
User created

C:\Documents and Settings\zouyang>rman catalog rman/rman123@orcl10
Recovery Manager: Release 10.1.0.2.0 - Production
Copyright (c) 1995, 2004, Oracle. All rights reserved.
RMAN-00571: ===============================================
RMAN-00569: ====== ERROR MESSAGE STACK FOLLOWS ==========
RMAN-00571: ===============================================
RMAN-00554: initialization of internal recovery manager package failed
RMAN-04004: error from recovery catalog database: ORA-01045: user RMAN lacks CREATE SESSION privilege; logon denied
-- 报错！要给rman用户分配一定的权限！
SQL> grant connect,resource,create session,recovery_catalog_owner
2 to rman;
Grant succeeded

C:\Documents and Settings\zouyang>rman catalog rman/rman123@orcl10
Recovery Manager: Release 10.1.0.2.0 - Production
Copyright (c) 1995, 2004, Oracle. All rights reserved.
connected to recovery catalog database
recovery catalog is not installed

RMAN> create catalog tablespace rman_tools;
recovery catalog created ——很好！！建立了！！

可是，当我重新连接，显示RMAN设置信息时又报错了！！
C:\Documents and Settings\zouyang>rman target sys/system catalog rman/rman123@orcl10
Recovery Manager: Release 10.1.0.2.0 - Production
Copyright (c) 1995, 2004, Oracle. All rights reserved.
connected to target database: ORCL (DBID=1227672490)
connected to recovery catalog database
RMAN> show channel for device type disk;
RMAN configuration parameters are:
RMAN-00571: ===============================================
RMAN-00569: ========= ERROR MESSAGE STACK FOLLOWS =======
RMAN-00571: ===============================================
RMAN-03002: failure of show command at 10/14/2009 10:32:36
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20001: target database not found in recovery catalog
RMAN>

又在网上查找原因，原来还需要注册数据库！！
第二步：Register Database
Each database to be backed up by RMAN must be registered！
RMAN> register database;
database registered in recovery catalog
starting full resync of recovery catalog
full resync complete
RMAN> show channel for device type disk;
RMAN configuration parameters are:CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'D:\BACKUP\RMAN\%d_%s.bak';
RMAN>

成功啦！！！
