【RAC】rac环境下的数据库备份与还原
一.1 BLOG文档结构图
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 | rac环境 |
db version | 11.2.0.1 | 11.2.0.1 |
ORACLE_SID | orastrac1 和 orastrac2 | orastrac1 和 orastrac2 |
db_name | orastrac | orastrac |
主机IP地址： | 192.168.1.31 192.168.1.32 | 192.168.1.31 192.168.1.32 |
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：

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：

一.3.7 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。
