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-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-00558: error encountered while parsing input commands

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-00558: error encountered while parsing input commands

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$ rmantarget '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=00005 name=/oracle/oracle9i/oradata/testmysiteok/example01.dbf

input datafile fno=00007 name=/oracle/oracle9i/oradata/testmysiteok/odm01.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 KeyCompletion TimeFilename/Handle

-------------------- ------ ------------------ --------------------

Backup Set 59016-OCT-05

Backup Piece 59116-OCT-05/oracle/testmysiteok20051016.dbf

Archive Log42429-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:
