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 rac数据库的备份集是如何恢复到单实例的数据库

② ASM文件系统到OS文件系统的转换

③ 一般的备份恢复过程

实验环境介绍

源库：11.2.0.1 rac库 2个节点

目标库：11.2.0.1 RHEL6.5

本文也可以理解成rac环境下的如何数据库迁移到单实例的数据库环境下，默认目标库已经安装好了同源库一样的数据库版本。

实验部分

实验目标

将11.2.0.1下的rac库备份并恢复到11.2.0.1下的单实例环境下。

源rac库执行

rac库需要执行备份并传递到目标库。

查看rac环境及创建测试表

我后续将在192.168.1.32即rac的第二个节点上执行操作，db_name为jmrac，数据库为归档模式，创建测试表lhr.rac_to_single_test，数据量为72510 行，其中有个crsstat命令，可以参考：【RAC】如何让Oracle RAC crs_stat 命令显示完整 http://blog.itpub.net/26736162/viewspace-1610957/

执行备份操作

备份脚本如下：

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@node2 ~]$ rman target /

Recovery Manager: Release 11.2.0.1.0 - Production on Fri May 29 11:12:51 2015

connected to target database: JMRAC (DBID=1916705604)

2> {

3> allocate channel c1 type disk;

4> allocate channel c2 type disk;

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

6> sql 'alter system archive log current';

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

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

9> release channel c1;

10> release channel c2;

11> }

using target database control file instead of recovery catalog

[oracle@node2 rman_back]$

将备份传递到target库

这个方法就多了，可以采用ftp上传下载，也可以采用NFS网络文件系统，或者scp命令都可以，这里我们采用scp直接传递。

源库：

[oracle@node2 rman_back]$ scp -r /home/oracle/rman_back oracle@192.168.59.129:/home/oracle

ssh: connect to host 192.168.59.129 port 22: Network is unreachable

lost connection

由于source db的IP为192.168.1.32，而目标库的IP为192.168.59.129，不在同一个网段，所以我对目标库再添加一块网卡，所以目标库的IP配置如下：

目标库再添加一块网卡后：

至此，源库rac上需要操作的内容已完成。

target库上执行

修改pfile文件生成spfile文件、生成pfile中的文件路径

主要有两方面的修改：

修改含文件路径的参数，达到符合当前服务器环境的实际情况，如audit_file_dest，control_files，db_recovery_file_dest
修改多实例相关的参数,如 cluster_database，带有实例名的前缀

源pfile文件内容：

这里需要注意的是，数据文件的转换，由于原rac库是asm存储的，所以到新环境需要采用set newname来转换一下，相关的可以参考哥的blog：【oracle官网】 Restoring a Database on a New Host http://blog.itpub.net/26736162/viewspace-1548104/，这里就直接操作了。

先得到转换的脚本：

2 from v$datafile a

3 union all

5 from v$tempfile a

6 union all

7 SELECT 'SQL "ALTER DATABASE RENAME FILE ''''' || a.MEMBER || ''''' to ''''' ||

8 a.MEMBER || ''''' ";'

9 FROM v$logfile a;

'SETNEWNAMEFORDATAFILE'||A.FILE#||'TO"'||A.NAME||'";'
