实验环境介绍
网站建设哪家好，找创新互联建站！专注于网页设计、网站建设、微信开发、微信小程序开发、集团企业网站建设等服务项目。为回馈新老客户创新互联还提供了甘孜州免费建站欢迎大家使用！
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 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：

[oracle@node2 rman_back]$
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：

[oracle@orcltest rman_back]$
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
