注意：在复制控制文件前，需要一致性关闭数据库；

查询当前数据库控制文件路径，创建新目录，添加新路径至参数文件；

centos@SYS> select name from v$controlfile;
NAME
---------------------------------------------
/u01/app/oracle/oradata/centos/control01.ctl
/u01/app/oracle/oradata/centos/control02.ctl
centos@SYS> show parameter control;

System altered.
centos@SYS>

[oracle@centos ~]$ mkdir -p /u01/app/oracle/control
[oracle@centos ~]$

一致性关闭数据库，并拷贝控制文件至新目录；

centos@SYS> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
centos@SYS> host
[oracle@centos ~]$ cd /u01/app/oracle

[oracle@centos centos]$ cd /u01/app/oracle/control
[oracle@centos control]$ ls
control03.ctl
[oracle@centos control]$

启库，查看新控制文件是否生效；
