oracle 控制檔案路徑修改--ORA-02095

資料庫從9i升級到11g的時候，一個控制檔案路徑放錯了，需要開個change糾正過來，在虛擬機器上進行相關測試：
step1: 檢視當前控制檔案的引數

SQL> select status,name,block_size,FILE_SIZE_BLKS,IS_RECOVERY_DEST_FILE from  v$controlfile;

 

STATUS   NAME                                               BLOCK_SIZE FILE_SIZE_BLKS IS_

-------- -------------------------------------------------- ---------- -------------- ---

 /u01/app/oracle/oradata/ANDREA/control01.ctl                    16384            594 NO

/u01/app/oracle/fast_recovery_area/ANDREA/control02.ctl      16384            594 NO

step2: 修改parameter control_files

alter system set control_files=(/u01/app/oracle/oradata/ANDREA/control01.ctl,

/u01/app/oracle/oradata/ANDREA/control03.ctl,

/u01/app/oracle/fast_recovery_area/ANDREA/control02.ctl)

scope=spfile;

ERROR at line 1:

ORA-02095: specified initialization parameter cannot be modified

---注意引數格式

alter system set control_files='/u01/app/oracle/oradata/ANDREA/control01.ctl',

'/u01/app/oracle/oradata/ANDREA/control03.ctl',

'/u01/app/oracle/fast_recovery_area/ANDREA/control02.ctl'

scope=spfile;
step3: shutdown instance
step4: cp  '/u01/app/oracle/oradata/ANDREA/control03.ctl  '/u01/app/oracle/oradata/ANDREA/control01.ctl
step5: startup instance
然後 檢視alert_*.log日誌內容。
