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 Size 2227944 bytes

Variable Size 704643352 bytes

Database Buffers 536870912 bytes

Redo Buffers 8921088 bytes

Database mounted.

ORA-03113: end - of -file on 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;

` GROUP`# THREAD# SEQUENCE # BYTES BLOCKSIZE MEMBERS ARC

---------- ---------- ---------- ---------- ---------- ---------- ---

STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

---------------- ------------- --------- ------------ ---------

SQL> alter database open resetlogs;

alter database open resetlogs

*

ERROR at line 1:

ORA-01139: RESETLOGS option only valid after an incomplete database recovery

SQL> recover database until time '2013-07-05'

Media recovery complete.

SQL> alter database open resetlogs;

Database altered.

成功。

注：如果 `alter` `database` `open` `resetlogs;执行提示`失败，那么 ``alter database open noresetlogs;
