ORA-03113: end-of-file on communication channel Process ID: 252 Session ID: 1 Serial number: 3

进入字符界面：

sqlplus  / as sysdba

startup nomount;

alter database mount;

alter database open;

报如下错误：

*
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Process ID: 252
Session ID: 1 Serial number: 3

 

我也从来没有遇到这个错误，只好上google 搜索，看了一堆资料。

其中有一篇文章

http://www.dbanotes.net/Oracle/ORA-03113.htm

提醒了我，其实 遇到数据库出错的时候，最先需要做的事就是查看

alter_orcl.log 这个文件。这个不是技术，而是方法论

然后去找  app/admin/orcl/bdump 目录下的alter 告警文件。

c:/>  sqlplus / nolog

sql> conn / as sysdba

　　　　Connected to an idle instance.

sql> startup nomount

ORACLE instance started.

Total System Global Area  426852352 bytes

Database Buffers             117440512 bytes
Redo Buffers                    6045696 bytes

sql> alter database  mount;

Database altered.

到这一个步骤，就停下来。

大家知道

nomount 状态 数据库获取spfile的配置 来启动数据库，其实这个时候我就可以

通过 show parameter  查看 background_dump_dest  这个参数 来了解

alter 文件到底存放在那里了。

mount 状态，数据库实例 已经 获取了 控制文件。控制文件里面有scn

有数据文件的指针，等等很多信息。

 

background_dump_dest  d:/app/diag/rdbms/orcl/orcl/trace

知道告警文件在什么地方，那就去查看和分析吧。

四选一，我选择四。

在操作系统层，删除归档文件。

在操作系统层面 删除目录 D:/APP/FLASH_RECOVERY_AREA/ORCL/ARCHIVELOG/2011_02_18/

下时间靠前的归档日志。

然后通过rman 来删除归档信息。

c:> set oracle_sid=orcl

c:> rman target /

RMAN> crosscheck archivelog all;
