ORA-27037--重建控制文件的時候報錯

<txt>ORA-00210: cannot open the specified control file

上面是log.xml的最近的部分

上面是稍遠的部分

控制文件的語句是

CREATE CONTROLFILE REUSE DATABASE "SOLODB" NORESETLOGS ARCHIVELOG
MAXLOGFILES 5
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 1
MAXLOGHISTORY 226

解決辦法：實際上要重建控制文件，但是一直報上面的錯誤。實際上從log.xml的報錯看，因為control_files是錯的，所以數據庫根本起不來。如果一開始control_files的是正確的，實際不需要重建控制文件。

最后發現是自己設置control_files參數的時候，值寫錯了。

正確的是

*.control_files='/u01/app/oracle/oradata/PROD1/controlfile/o1_mf_bpy15704_.ctl','/u01/app/oracle/flash_recovery_area/PROD1/controlfile/o1_mf_bpy15799_.ctl'

錯誤的是

*.control_files='/u01/app/oracle/product/11.2.0/dbhome_1/dbs/ora_control01.ctl,/u01/app/oracle/product/11.2.0/dbhome_1/dbs/ora_control02.ctl'

但是修改為正確的格式仍然無法創建控制文件，最后連路徑也模仿正確的格式，才創建成功。

創建成功后,create pfile from spfile;recover database;

這兩步很有必要。
