1.首先查看一下Oracle的数据文件
SQL> select name from v$datafile；
NAME
/dev/rora_system
/dev/rora_undo1
/dev/rora_sysaux
/dev/rora_users
/dev/rora_example
2.建立RMAN所需的表空间，这里采用裸设备“/dev/rora_backup”
SQL> create tablespace ora_backup datafile'/dev/rora_backup' size 500M；
Tablespace created.
进行查看确认
SQL> select name from v$datafile；
NAME
/dev/rora_system
/dev/rora_undo1
/dev/rora_sysaux
/dev/rora_users
/dev/rora_example
/dev/rora_backup
6 rows selected.
已经发现ora_backup表空间
3.建立RMAN用户以及设定密码和用户表空间
SQL> create user rman identified by rman default tablespace ora_backup temporay tablespace temp
2 ；
create user rman identified by rman default tablespace ora_backup temporay tablespace temp
*
ERROR at line 1：
ORA-00922： missing or invalid option
在此处出错，原来是temporay打错，继续。
SQL> create user rman identified by rman default tablespace ora_backup temporary tablespace temp；
User created.
呵呵，成功
4.给用户授权
SQL> grant connect，resource，recovery_catalog_owner to rman
2 ；
Grant succeeded.
5.连接到数据库
SQL> rman target 'zhirui' catalog rman/rman
SP2-0734： unknown command beginning "rman targe……" - rest of line ignored.
呵呵，又出错了，没退出SQL.
SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning， OLAP and Data Mining options
$ rman target 'zhirui'catalog rman/rman
这下应该可以了吧
