ORA-03113 end-of-file on communication channel 问题解决

目前遇到过两种情况 ，如下：

CASE 1:

SQL> startup force

ORACLE instance started.

Total System Global Area 2672361472 bytes

Fixed Size                  2256232 bytes

Variable Size            1392509592 bytes

Database Buffers         1258291200 bytes

Redo Buffers               19304448 bytes

Database mounted.

ORA-03113: end-of-file on communication channel

Process ID: 6300

Session ID: 193 Serial number: 3

文档：

ORA-03113: end-of-file on communication channel

Cause: The connection between Client and Server process was broken.

Action: There was a communication error that requires further investigation.  

实际中多为TRACE 文件占空间太多。

解决如下：（非生产环境，所以把所有的TRACE文件都删除了）

SQL> startup nomount;
