现在 想把这两个文件放在统一的位置去,可以使用下面办法:
1.修改standby_file_management参数
alter system set standby_file_management='manual';
2.备库启动到mount状态
shutdown immediate
startup mount
3.拷贝数据文件到目标路径下
backup as copy datafile 82 format ='+data';
backup as copy datafile 83 format ='+data';
4.切换到新路径下
switch datafile 82,83 to copy;
5.迁移部分数据文件后可打开数据库
alter database open;
recover managed standby database disconnect from session;
