  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
  --------------------------------------------------------------------------------
  //9i/oradata/testmysiteok/system01.dbf
  //9i/oradata/testmysiteok/undotbs01.dbf
  //9i/oradata/testmysiteok/cwmlite01.dbf
  //9i/oradata/testmysiteok/drsys01.dbf
  //9i/oradata/testmysiteok/example01.dbf
  //9i/oradata/testmysiteok/indx01.dbf
  //9i/oradata/testmysiteok/odm01.dbf
  //9i/oradata/testmysiteok/tools01.dbf
  //9i/oradata/testmysiteok/users01.dbf
  //9i/oradata/testmysiteok/xdb01.dbf
  //oradata/webdb_file1.dbf
  
  NAME
  --------------------------------------------------------------------------------
  //oradata/webdb_file2.dbf
  //oradata/webdb_file3.dbf
  //oradata/webdb_file4.dbf
  
  14 rows selected.
  
  2. 建立catalog表空间为back_up
  
  SQL> create tablespace back_up datafile '//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-00571: ===========================================================
  RMAN-00558: error encountered while parsing input commands
  RMAN-01005: syntax error: found "backup": expecting one of: "double-quoted-string, identifier, single-quoted-string"
  RMAN-01007: at line 1 column 27 file: standard input
  
  RMAN-00571: ===========================================================
  RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

  RMAN-01005: syntax error: found ";": expecting one of: "allocate, alter, backup, beginline, blockrecover, catalog, change, connect, copy, create, crosscheck, configure, duplicate, debug, delete, drop, exit, endinline, host, {, library, list, mount, open, print, quit, recover, register, release, replace, report, renormalize, reset, restore, resync, rman, run, rpctest, set, setlimit, sql, spool, startup, shutdown, send, show, test, upgrade, validate"
  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
  input datafile fno=00001 name=//9i/oradata/testmysiteok/system01.dbf
  input datafile fno=00002 name=//9i/oradata/testmysiteok/undotbs01.dbf
  input datafile fno=00005 name=//9i/oradata/testmysiteok/example01.dbf

  input datafile fno=00008 name=//9i/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
   Backup Piece    591  16-OCT-05     //testmysiteok20051016.dbf
  Archive Log     424  29-SEP-05     //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
  -------------------- ------ ------------------ --------------------
  Backup Set      590  16-OCT-05
