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
[oracle@oracle11g orcl]$ ll total 1771904 -rw-r----- 1 oracle oinstall 9748480 Jun 18 09:54 control02.ctl -rw-r----- 1 oracle oinstall 52429312 Jun 18 09:48 redo01.log -rw-r----- 1 oracle oinstall 52429312 Jun 18 09:48 redo02.log -rw-r----- 1 oracle oinstall 52429312 Jun 18 09:50 redo03.log -rw-r----- 1 oracle oinstall 555753472 Jun 18 09:50 sysaux01.dbf -rw-r----- 1 oracle oinstall 807411712 Jun 18 09:50 system01.dbf -rw-r----- 1 oracle oinstall 20979712 Jun 18 09:48 temp01.dbf -rw-r----- 1 oracle oinstall 209723392 Jun 18 09:50 TOBACCO.dbf -rw-r----- 1 oracle oinstall 57679872 Jun 18 09:50 undotbs01.dbf -rw-r----- 1 oracle oinstall 14426112 Jun 18 09:50 users01.dbf [oracle@oracle11g orcl]$ cp control02.ctl control01.ctl [oracle@oracle11g orcl]$ ll total 1781424 -rw-r----- 1 oracle oinstall 9748480 Jun 18 09:54 control01.ctl -rw-r----- 1 oracle oinstall 9748480 Jun 18 09:54 control02.ctl -rw-r----- 1 oracle oinstall 52429312 Jun 18 09:48 redo01.log -rw-r----- 1 oracle oinstall 52429312 Jun 18 09:48 redo02.log -rw-r----- 1 oracle oinstall 52429312 Jun 18 09:50 redo03.log -rw-r----- 1 oracle oinstall 555753472 Jun 18 09:50 sysaux01.dbf -rw-r----- 1 oracle oinstall 807411712 Jun 18 09:50 system01.dbf -rw-r----- 1 oracle oinstall 20979712 Jun 18 09:48 temp01.dbf -rw-r----- 1 oracle oinstall 209723392 Jun 18 09:50 TOBACCO.dbf -rw-r----- 1 oracle oinstall 57679872 Jun 18 09:50 undotbs01.dbf -rw-r----- 1 oracle oinstall 14426112 Jun 18 09:50 users01.dbf
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
