ORA-03113: end-of-file on communication channel （通信通道的文件結尾）Oracle數據庫啓動異常

機器遭遇斷電，之後oracle就不能啓動了，報錯ORA-03113: end-of-file on communication channel （通信通道的文件結尾）

首先，打開命令行cmd：
C:\Documents and Settings\Administrator>sqlplus system/123456
SQL*Plus: Release 11.2.0.1.0 Production on 星期一 11月 11 11:31:13 2013

連接到:

With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> conn /as sysdba
已連接。

SQL> startup

網上分析，可能由於昨晚數據庫強制關閉，導致文件狀態可能不一致，因爲正常關閉數據庫會同步校驗各文件，使得重新啓動的時候文件時間點一致。解決方案如下

啓動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;

恢復數據庫

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'

SQL> alter database open resetlogs;

Database altered.

成功。
