控制文件多路径复用ORA-00205错误

1.配置控制文件多路径复用，执行以下命令成功

SQL> alter system set control_files='/oradata/orcl/control01.ctl','/oradata/orcl/control02.ctl' scope=spfile;

System altered.

SQL> 

2.正常关闭数据库

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> 

3.操作系统层面复制控制文件，实现多路径复用

4.启动数据库，到mount阶段数据库报错

SQL> alter database mount;
alter database mount
*
ERROR at line 1:
ORA-00214: control file '/oradata/orcl/control02.ctl' version 2480 inconsistent
with file '/oradata/orcl/control01.ctl' version 2477

后台日志

alter database mount
ORA-00210: cannot open the specified control file
ORA-00202: control file: '/oradata/orcl/control01.ctl,/oradata/orcl/control02.ctl'
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3
ORA-205 signalled during: alter database mount...

到这里非常的奇怪，根据提示是无法打开这个控制文件，获取不到这个文件状态，操作系统层面无法找到这个文件

5.重新执行SQL语句，使用双引号，启动数据库成功

SQL> alter system set control_files="/oradata/orcl/control01.ctl","/oradata/orcl/control02.ctl" scope=spfile;

System altered.

SQL> startup force
ORACLE instance started.
