实验环境介绍
源库：1 1.2.0.1 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。
另外注意，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。

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。
rac 库需要执行备份并传递到目标库。

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 <a http:="" blog.itpub.net="" 26736162="" viewspace-1610957="" "="" ?="" style=";padding: 0px"> http://blog.itpub.net/26736162/viewspace-1610957/

1.3.2.3 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/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：

1.3.2.4
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。
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||'";'
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

可以看到数据已经恢复。
做到这步，都还没有完啊，只是说目的基本达成，最后还需要收尾的工作。清除未使用线程的 redo 日志组，操作如下：
一、 清除未使用的 redo

THREAD# INSTANCE STATUS ENABLED

GROUP# THREAD# ARC STATUS

2 1 YES UNUSED

生产环境可以再增加一些日志组。
二、 清除多余的 undo 文件
我们知道rac 中每个节点使用的都是自己的undo，所以有2个undo文件，这里可以清除，也可以不用清除，因为有的时候undo坏了可以很迅速的切换到另外的undo 空间，清理过程如下：
SQL> select name from v$tablespace where name like 'UNDO%';
NAME
------------------------------
UNDOTBS1
UNDOTBS2
SQL> show parameter undo_tablespace;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
undo_tablespace string UNDOTBS1
SQL> drop tablespace undotbs2 including contents and datafiles;
Tablespace dropped.

1.3.4 实验总结
rac数据库迁移到单实例环境下的步骤和单实例的数据库迁移到单实例环境基本是一样的，只是在最后还原的时候需要设置2 个thread 即可。
至此，rac 数据库迁移到单实例环境下的操作步骤基本完毕，至于配置监听和tns 等工作都是基本的，大家自己完成即可，这里就不再演示了，另外实验中需要关注的几个地方，我都特别做了说明。
以上的文章是转载别人的，其中有一点需要说一下：就是我们在源端的rac环境中备份完成传输的目标端的单实例数据库中以后使用rman会完成控制文件，在恢复数据文件的时候会报
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 12/08/2018 05:03:36
RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 4 found to restore
RMAN-06023: no backup or copy of datafile 3 found to restore
RMAN-06023: no backup or copy of datafile 2 found to restore
RMAN-06023: no backup or copy of datafile 1 found to restore
报错出现的原因：由于在生产上备份的目录和测试库上的存放备份文件的目录不一致导致的。
RMAN将执行一个隐式交叉检查，将备份标记为过期。
RMAN在备份期间放置备份的位置查找备份。备份已被放置在新主机上的新目录中。备份被保存到磁盘上，并在新主机的另一个不同位置恢复。可以使用以下命令查看：
RMAN> crosscheck backup;
RMAN> crosscheck copy;
发出RMAN crosscheck命令将验证备份是否存在于备份期间所放置的磁盘位置上。
当客户将备份放在不同的位置时，会发生过期状态。
可用状态表明RMAN知道备份，并将在还原期间使用备份。
为了告诉RMAN磁盘上备份的位置已经更改，请使用RMAN catalog命令。
的例子,编目多个备份在一个目录:
下面的示例编目了复制到/tmp director中的备份片段的目录：
执行
RMAN> CATALOG START WITH '/tmp/';
有的时候我们执行完成以后还会报错这个时候需要调整一下incaraction.
使用list incarnation；
reset database to incarnation 2
