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~:

rac环境下的数据库备份与还原

rman恢复数据库的一般步骤

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黄色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33thread 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:

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,3rac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 /

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

9>  release channel c1;

10>  release channel c2;

11> }

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2thread

 

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。
