前言部分

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 单实例环境的备份集如何恢复到rac环境(重点)

② rman恢复数据库的一般步骤

③ rac环境的简单操作

实验环境介绍

源库：11.2.0.1 RHEL6.5 单实例

目标库：11.2.0.1 RHEL6.5 rac环境

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 dbtarget db
db 类型单实例rac环境
db version11.2.0.111.2.0.1
ORACLE_SIDorastracorastrac1 和 orastrac2
db_nameorastracorastrac
主机IP地址：192.168.59.129192.168.1.31 192.168.1.32

先描述下大致步骤：

  • 源端创建备份集；
  • 目标端安装数据库软件和集群件，并配置好共享存储（安装rac的时候一般已经配置好了）；
  • 复制源端备份集到目标端；
  • 目录端任意节点执行正常恢复，恢复时注意要将 spfile,controlfile,datafile,redofile 等路径改到共享存储上，恢复完后这会儿仍然是个单实例数据库；
  • 修改初始化参数、增加 UNDO 表空间、增加 REDOLOG 线程组，重建密钥文件，目标端任意节点执行；
  • 目标端各个节点配置监听及网络服务名；
  • 将新建的数据库配置到 crs，目标端任意节点执行即可。

实验部分

实验目标

将单实例的备份集成功的恢复到rac环境下，并添加数据库到crs环境。

源库操作

source库上需要做的操作主要是备份和创建测试用户。

静默创建一个单实例的测试库

首先修改归档模式，这样创建的数据库默认为归档模式，然后我们在源库上静默创建一个单实例的库，sid为orastrac，为oracle single instance to rac，关于静默安装数据库参考：

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：

run

{

allocate channel c1 type disk;

allocate channel c2 type disk;

backup database format '/home/oracle/rmanback/full%n%T%t%s%p.bak';

sql 'alter system archive log current';

backup archivelog all format '/home/oracle/rmanback/arch%d%T%s_%p.bak' delete input;

backup current controlfile format '/home/oracle/rmanback/ctl%d%T%s_%p.bak';

release channel c1;

release channel c2;

}

执行过程如下：

[oracle@orcltest ~]$ rman target /

插曲：注意，这里如果想让控制文件的格式为ASM格式，可以这样设置控制文件的路径：

pfile文件中的control_files这样写： *.control_files='+DATA','+ARCH'，然后还原的时候就可以直接还原为asm格式的文件了，我这里由于是后边补上的，所以就不采用如下的形式了，如下：

RMAN> restore controlfile from '/home/oracle/rman_back/ctl_ORASTRAC_20150601_7_1.bak';

Starting restore at 01-JUN-2015 17:59:39

创建os文件路径，注意在节点一和节点二都执行：

[oracle@node1 ~]$ mkdir -p /u01/app/oracle/admin/orastrac/adump

[oracle@node1 ~]$

注意哟，创建的 spfile 可是要放到共享存储上去的：
