ora-00205报错解决

早上启动数据库时候报如下错误：

[oracle@jason ~]$ sqlplus /nolog

查看警告日志发现如下报警信息：

Mon Jul 18 22:11:58 2011
ORA-00202: control file: '/orac/oradata/jason/control01.ctl'
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
 

查看'/orac/oradata/jason目录下存在control01.ctl文件，百度ORA_00205.问题得以解决，原来是该控制文件损坏导致不能启动数据库，复制control02.ctl文件重名为control01.ctl，或者修改初始化参数文件的控制文件参数取消control01.ctl文件路径。重新启动数据库问题得以解决！
