Oralce 11g OCM之管理恢复目录(CATALOG)

oralce 11g OCM之管理恢复目录

一：11g 版本中catalog的创建以及数据库的注册方式几乎和10g一模一样，如下：

1.创建catalog存放数据的表空间

create tablespace cat_tbs datafile ‘/data01/cat_tbs01.dbf’ size 10M autoextend on next 10M maxsize 500m;

2.创建catalog用户

create user rman identified by oracle default tablespace cat_tbs quota unlimited on cat_tbs;
grant recovery_catalog_owner to rman;

3.创建catalog并注册数据库

[oracle@luda 21:40:23|/oracle/product/11.2/network/admin]rman catalog rman/oracle@luda

二：11g新特性 虚拟恢复目录

《Backup and Recovery User’s Guide》第13章 — Creating and Managing Virtual Private Catalogs

Catalog用来管理存储多个数据库的备份信息，Rman脚本等，在11g中ORACLE推出关于RMAN catalog的一个新特性Virtual Private Catalogs，相对catalog用来管理多个数据库备份等相关信息，Virtual Private Catalogs的主要作用是一个Virtual Private Catalogs对应一个数据库的DBA，在管理的时候可以避免catalog恢复时候导致其他数据库的相关备份信息，脚本等丢失，而每一个Virtual Private Catalogs可以把变动只会针对对应管理员管理的数据库，而不是所有的数据库。一个catalog下不限制Virtual Private Catalog的个数，Virtual Private Catalogs的归属用户和Catalog的归属用户必须不同。

创建虚拟私有目录服务步骤

1.创建相关表空间

SQL> create tablespace vptbs datafile ‘/data01/vptbs01.dbf’ size 50M;

Tablespace created.

2.创建相关用户

SQL> create user luda_vp identified by oracle default tablespace vptbs quota unlimited on vptbs;

User created.

3.给予用户以及catalog权限

给予用户数据库权限

SQL> grant recovery_catalog_owner to luda_vp;

Grant succeeded.

赋予catalog权限

[oracle@luda 23:03:24|~]rman catalog rman/oracle@luda

Recovery Manager: Release 11.2.0.1.0 – Production on Tue Nov 20 23:03:43 2012

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to recovery catalog database

RMAN> grant catalog for database luda to luda_vp;

Grant succeeded.

RMAN> grant register database to luda_vp;

Grant succeeded.

RMAN>

4.使用虚拟目录用户登陆rman创建虚拟目录

[oracle@luda 23:06:18|~]rman catalog luda_vp/oracle@luda

Recovery Manager: Release 11.2.0.1.0 – Production on Tue Nov 20 23:06:35 2012

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to recovery catalog database

RMAN> create virtual catalog;

found eligible base catalog owned by RMAN
created virtual catalog against base catalog owned by RMAN

5.移除虚拟目录用户权限

使用catalog用户登陆rman

[oracle@luda 23:10:28|~]rman catalog rman/oracle@luda

Recovery Manager: Release 11.2.0.1.0 – Production on Tue Nov 20 23:10:45 2012

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to recovery catalog database

RMAN>

使用revoke命令移除相关权限

RMAN> revoke catalog for database luda from luda_vp
2> ;

Revoke succeeded.

RMAN> revoke register database from luda_vp;

Revoke succeeded.

RMAN>

6.删除虚拟目录

使用虚拟目录用户登陆rman，执行删除操作

[oracle@luda 23:14:39|~]rman catalog luda_vp/oracle@luda

Recovery Manager: Release 11.2.0.1.0 – Production on Tue Nov 20 23:14:53 2012

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to recovery catalog database
recovery catalog is not installed

RMAN> drop catalog;

recovery catalog owner is LUDA_VP
enter DROP CATALOG command again to confirm catalog removal

RMAN> drop catalog;

virtual catalog dropped

三.catalog的迁移以及删除

catalog的信息可以在用户之间进行迁移，可以是同库的用户也可以是不同库的用户。
通过import catalog相关命令，可以指定需要导入信息的实例的DBID，DB_NAME等。

1.首先测试为同库用户：

在luda实例下创建另外一个catalog用户：

[oracle@luda 21:58:08|~]sq

SQL*Plus: Release 11.2.0.1.0 Production on Wed Nov 21 21:58:10 2012

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 – Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> create user rman1 identified by oracle default tablespace cat_tbs quota unlimited on  cat_tbs;

User created.

SQL> grant recovery_catalog_owner to rman1;

Grant succeeded.

使用rman1用户创建catalog

[oracle@luda 22:02:59|~]rman catalog rman1/oracle@luda

Recovery Manager: Release 11.2.0.1.0 – Production on Wed Nov 21 22:03:10 2012

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to recovery catalog database

RMAN> create catalog;

recovery catalog created

导入rman用户管理的catalog 指定数据库实例为luda

[oracle@luda 22:06:35|~]rman catalog rman1/oracle@luda

Recovery Manager: Release 11.2.0.1.0 – Production on Wed Nov 21 22:06:42 2012

Copyright (c) 1982, 2009, Oracle and/or its affiliates.  All rights reserved.

connected to recovery catalog database

RMAN> import catalog rman/oracle@luda db_name=luda;

Starting import catalog at 21-NOV-12
connected to source recovery catalog database
import validation complete
database unregistered from the source recovery catalog
Finished import catalog at 21-NOV-12

查询导入后rman和rman1用户catalog信息

[oracle@luda 22:11:28|~]rman target/ catalog rman/oracle@luda

Recovery Manager: Release 11.2.0.1.0 – Production on Wed Nov 21 22:11:48 2012

connected to target database: LUDA (DBID=518309061)
connected to recovery catalog database

RMAN> report schema;

RMAN> exit

List of Permanent Datafiles
===========================
File Size(MB) Tablespace           RB segs Datafile Name
—- ——– ——————– ——- ————————
1    700      SYSTEM               YES     /data01/system01.dbf
2    500      SYSAUX               NO      /data01/sysaux01.dbf
3    90       UNDOTBS1             YES     /data01/undotbs01.dbf
4    5        USERS                NO      /data01/users01.dbf
5    100      EXAMPLE              NO      /data01/example01.dbf
6    10       CAT_TBS              NO      /data01/cat_tbs01.dbf
7    50       VPTBS                NO      /data01/vptbs01.dbf

List of Temporary Files
=======================
File Size(MB) Tablespace           Maxsize(MB) Tempfile Name
—- ——– ——————– ———– ——————–
1    29       TEMP                 32767       /oracle/oradata/LUDA/datafile/o1_mf_temp_8b3t8vw4_.tmp

通过测试可以发现rman用户的catalog信息导入rman1用户的catalog之后，rman用户的catalog信息就清除掉了；而实际在使用过程中可以使用NO UNREGISTER参数来指定不删除源用户（这里指RMAN用户）的catalog信息。

2.不同数据库之间的用户的catalog迁移

不同用户数据库用户之间的catalog迁移参考测试1中的用户连接

import catalog rman/oracle@luda db_name=luda;

比如是把rman用户下OMR数据库的catalog信息迁移到rman1
命令如下：

rman catalog rman1/oracle@luda 登陆rman
import catalog rman/oracle@omr db_name=omr;
