ORA-00205:errorinidentifyingcontrolfile,checkalertlo-mysql教程

文章根据自己碰到的关于ORA-00205: error in identifying control file, check alert log for more info 错误进行分析有需要的同学可参考一下。

境：oracle10gR2 solaris10
操作：在没有创建pfile的情况下，直接执行了以下命令
1 SQL>create pfile from spfile;
2 SQL>shutdown immediate
3 SQL>startup
4 ORA-00205: error in identifying control file, check alert log for more info
查看alter_TEST.log文件

原因是因为启动时未找到spfile则调用了数据库默认的init.ora，但是其默认值与现有数据库信息不匹配导致数据库不能启动。
解决方案：

注：再做pfile启动数据库时要注意是否已经通过spfile生成pfile。
