搭建参见文章http://www.jb51.cc/article/p-yvzgbjsu-bqm.html,搭好后，做switch over:

1 检查参数fal_server,fal_client,log_archive_dest_2,log_file_name_convert,data_file_name_convert,

standby_file_management

源：

fal_server=standby

fal_cleint=db

@H_403_13@altersystemsetdb_file_name_convert='/data','+data'scope=spfile; altersystemsetlog_file_name_convert='/data','+data'scope=spfile;

standby:

fal_server=db

fal_client=standby

standby_file_management=auto

2 切换前rac需关闭至一个实例

3 检查是否有gap

4 切换：

源：

@H_403_13@sql>alterdatabasecommittoswitchovertostandbywithsessionshutdown;

这里切换后，源端全自动shutdown abort;

--standby
