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

channel ORA_DISK_1: starting piece 1 at 07-AUG-05
channel ORA_DISK_1: finished piece 1 at 07-AUG-05

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

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
