Oracle错误ORA-03113: end-of-file on communication channel处理办法

机器遭遇断电，之后oracle就不能启动了，报错ORA-03113: end-of-file on communication channel （通信通道的文件结尾）

SQL> startup

ORACLE instance started.

Total System Global Area 1252663296 bytes

Fixed Size2227944 bytes

ORA-03113: end-of-fileon communication channel

Process ID: 8117

Session ID: 191 Serial number: 3

网上分析，可能由于昨晚数据库强制关闭，导致文件状态可能不一致，因为正常关闭数据库会同步校验各文件，使得重新启动的时候文件时间点一致。解决方案如下

启动DB

SQL> conn / as sysdba

Connected to an idle instance.

SQL> startup mount

ORACLE instance started.

直接reset不成功

SQL> select* from v$log;

成功。

注：如果 alterdatabase open resetlogs;执行提示失败，那么alter database opennoresetlogs;
