【IT168 服务器学院】 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

　　RMAN> connect catalog rman/rman;
　　
　　connected to recovery catalog database
　　recovery catalog is not installed
　　
　　RMAN> create catalog tablespace backup;
　　
　　RMAN-00571: ===========================================================
　　RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

　　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
　　input datafile fno=00001 name=/oracle/oracle9i/oradata/testmysiteok/system01.dbf
　　input datafile fno=00002 name=/oracle/oracle9i/oradata/testmysiteok/undotbs01.dbf

　　input datafile fno=00008 name=/oracle/oracle9i/oradata/testmysiteok/tools01.dbf
　　channel ORA_DISK_1: starting piece 1 at 07-AUG-05
　　channel ORA_DISK_1: finished piece 1 at 07-AUG-05
　　piece handle=/data/ora_backup/testmysiteok_04grgroc_4_1 comment=NONE
　　channel ORA_DISK_1: backup set complete, elapsed time: 00:00:36
　　Finished backup at 07-AUG-05
　　
　　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
　　-------------------- ------ ------------------ --------------------
　　Backup Set　　　　　 590　　16-OCT-05

　　Archive Log　　　　　424　　29-SEP-05　　　　　/oracle/OraHome/dbs/arch1_56.dbf
　　
　　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
　　Deleting the following obsolete backups and copies:
　　Type　　　　　　　　 Key　　Completion Time　　Filename/Handle
