控制文件多路徑複用ORA-00205錯誤

1.配置控制文件多路徑複用，執行如下命令成功

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

2.正常關閉數據庫

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

3.操做系統層面複製控制文件，實現多路徑複用

[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.啓動數據庫，到mount階段數據庫報錯

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

 

後臺日誌

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...

 

到這裏很是的奇怪，根據提示是沒法打開這個控制文件，獲取不到這個文件狀態，操做系統層面沒法找到這個文件

 

5.從新執行SQL語句，使用雙引號，啓動數據庫成功
