一.2 前言部分

一.2.1 导读

各位技术爱好者，看完本文后，你可以掌握如下的技能，也可以学到一些其它你所不知道的知识，~O(∩_∩)O~：

① rac环境下的数据库备份与还原

② rman恢复数据库的一般步骤

③ rac环境的简单操作

注意：本篇BLOG中代码部分需要特别关注的地方我都用***背景和红色字体来表示，比如下边的例子中，thread 1的最大归档日志号为33，thread 2的最大归档日志号为43是需要特别关注的地方。

一.2.4 本文简介

本文基于如何将单实例的数据库备份恢复到rac环境下，至于rac环境的备份集如何恢复到单实例及rac环境的备份集恢复到rac环境的实验请参考相关文章链接部分。

实验的一些数据库环境参考如下表格：

项目

source db

target db

db 类型

rac环境

db version

11.2.0.1

ORACLE_SID

orastrac1 和 orastrac2

db_name

orastrac

一.3 实验部分

一.3.1 实验目标

验证rac数据库环境下的备份和恢复操作。

一.3.2 查看rac环境

target库已经有4个库，3个rac库处于close状态，orastrac处于online状态。

一.3.4 source库执行备份操作

备份脚本如下，注意控制文件需要最后备份，在节点2上执行备份：

run

{

allocate channel c1 type disk;

allocate channel c2 type disk;

backup database format '/home/oracle/rman_back/full_%n_%T_%t_%s_%p.bak';

sql 'alter system archive log current';

backup archivelog all format '/home/oracle/rman_back/arch_%d_%T_%s_%p.bak' delete input;

backup current controlfile format '/home/oracle/rman_back/ctl_%d_%T_%s_%p.bak';

release channel c1;

release channel c2;

}

执行过程如下：

[oracle@node2 ~]$ rman target /

Recovery Manager: Release 11.2.0.1.0 - Production on Tue Jun 2 13:36:21 2015

connected to target database: ORASTRAC (DBID=1317814272)

using target database control file instead of recovery catalog

3> allocate channel c1 type disk;

4> allocate channel c2 type disk;

5> backup database format '/home/oracle/rman_back/full_%n_%T_%t_%s_%p.bak';

6> sql 'alter system archive log current';

7> backup archivelog all format '/home/oracle/rman_back/arch_%d_%T_%s_%p.bak' delete input;

8> backup current controlfile format '/home/oracle/rman_back/ctl_%d_%T_%s_%p.bak';

9> release channel c1;

10> release channel c2;

11> }

db_recovery_file_dest_size of 3882 MB is 4.43% used. This is a

user-specified limit on the amount of space that will be used by this

database for recovery-related files, and does not reflect the amount of

space available in the underlying filesystem or ASM diskgroup.

可以看到数据已经恢复，但是实例只启动了一个，我们来启动第二个实例：一.3.6.5 修复另一个节点的pfile

[oracle@node1 dbs]$ more initorastrac1.ora

SPFILE='+DATA/orastrac/parameterfile/spfileorastrac.ora'

[oracle@node1 dbs]$

[oracle@node1 dbs]$ srvctl modify database -d orastrac -p +DATA/orastrac/parameterfile/spfileorastrac.ora

[oracle@node1 dbs]$ srvctl start database -d orastrac

[oracle@node1 dbs]$

[oracle@node1 dbs]$ srvctl status database -d orastrac

Instance orastrac1 is running on node node1

Instance orastrac2 is running on node node2

[oracle@node1 dbs]$

一.3.7 实验总结

采用asm来存储的rac环境下的数据库备份和还原与单实例下os文件系统的备份和还原基本一样，不同的是recover的时候，需要设置2个thread。

一.4 总结

到此所有的处理算是基本完毕，过程很简单，但是不同的场景处理方式有很多种，我们应该学会灵活变通。
