ORA-00205: ?????????, ??????, ???????
出了这种问题,首先想到要去看告警日志文件:
.....
Tue May 05 00:48:35 2015
ALTER DATABASE MOUNT
ORA-00210: cannot open the specified control file
ORA-00202: control file: '/u01/app/oracle/oradata/orcl3939/control03.ctl'
ORA-27037: unable to obtain file status
Linux Error: 2: No such file or directory
.....
问题很明显了,3号控制文件出了问题,无法打开,怀疑已经损坏,此时有两种解决方法:
1.比较简单的就是重建3号控制文件,重启解决问题
[oracle@localhost ~]$ cp control01.ctl control03.ctl
2.删除spfile
已正常打开数据库:
