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

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: ===============================================
RMAN-03002: failure of show command at 10/14/2009 09:30:02
RMAN-06429: RCVCAT database is not compatible with this version of RMAN

RMAN>

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

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

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

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！！！
