rman的简单使用: catalog的建立，全备份，保留备份策略，删除过期备份。
1. 查看当前数据库的数据文件
SQL> select name from V$datafile;
NAME
--------------------------------------------------------------------------------
/Oracle/oracle9i/oradata/testmysiteok/system01.dbf
/oracle/oracle9i/oradata/testmysiteok/undotbs01.dbf
/oracle/oracle9i/oradata/testmysiteok/cwmlite01.dbf
/oracle/oracle9i/oradata/testmysiteok/drsys01.dbf
/oracle/oracle9i/oradata/testmysiteok/example01.dbf
/oracle/oracle9i/oradata/testmysiteok/indx01.dbf
/oracle/oracle9i/oradata/testmysiteok/odm01.dbf
/oracle/oracle9i/oradata/testmysiteok/tools01.dbf
/oracle/oracle9i/oradata/testmysiteok/users01.dbf
/oracle/oracle9i/oradata/testmysiteok/xdb01.dbf
/oracle/oradata/webdb_file1.dbf
NAME
--------------------------------------------------------------------------------
/oracle/oradata/webdb_file2.dbf
/oracle/oradata/webdb_file3.dbf
/oracle/oradata/webdb_file4.dbf
14 rows selected.
2. 建立catalog表空间为back_up
SQL> create tablespace back_up datafile '/oracle/oradata/catalog.dbf' size 50m;
Tablespace created.
3. 建立rman用户密码为rman,rman默认的表空间为back_up,使用临时表空间temp
SQL> create user rman identified by rman default tablespace back_up temmporary tablespace temp;
create user rman identified by rman default tablespace back_up temmporary tablespace temp
*
ERROR at line 1:
ORA-00922: missing or invalid option
SQL> create user rman identified by rman default tablespace back_up temporary tablespace temp;
User created.
4. 给rman用户授权
SQL> grant connect,resource,recovery_catalog_owner to rman;
Grant sUCceeded.
SQL> quit
Disconnected from Oracle9i Enterprise Edition Release 9.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production
5. 连接或者创建catalog到表空间 back_up
bash-2.05$ rman
Recovery Manager: Release 9.2.0.1.0 - 64bit Production
Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.
RMAN> connect catalog rman/rman;
connected to recovery catalog database
recovery catalog is not installed
RMAN> create catalog tablespace backup;

RMAN-01007: at line 1 column 33 file: standard input
RMAN> create catalog tablespace back_up;
recovery catalog created
RMAN> quit
Recovery Manager complete.
6. 连接到sid 为testmysiteok的 catalog上 ，并注册testmysiteok数据库
bash-2.05$ rman target 'testmysiteok' catalog rman/rman
Recovery Manager: Release 9.2.0.1.0 - 64bit Production
Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.
target database PassWord:
connected to target database: testmysiteOK (DBID=3999769622)
connected to recovery catalog database
RMAN> register database;
database registered in recovery catalog
starting full resync of recovery catalog
full resync complete
7. 全备份testmysiteok数据库
RMAN> backup full tag 'testmysiteok' format '/data/ora_backup/testmysiteok_%u_%s_%p' database;
Starting backup at 07-AUG-05
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=31 devtype=DISK
channel ORA_DISK_1: starting full datafile backupset
channel ORA_DISK_1: specifying datafile(s) in backupset
including current SPFILE in backupset
including current controlfile in backupset

8. 设置保留最近的3次备份
RMAN> configure retention policy to redundancy 3;
old RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;
new RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO REDUNDANCY 3;
new RMAN configuration parameters are successfully stored
starting full resync of recovery catalog
full resync complete
9. 查看过期的备份
RMAN> report obsolete;
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 2
Report of obsolete backups and copies
Type Key Completion Time Filename/Handle
-------------------- ------ ------------------ --------------------

10. 查看所有备份
RMAN> list backup;
11. 删除过期备份
RMAN> delete obsolete;
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 2
using channel ORA_DISK_1
