避免ORA-00942的错误。

5>.检查同一个网上是否有重复的IP地址

Cause:The table or view entered does not exist,a synonym that is jnot allowed here was used,or a view was
Cause:A rollback segment can only be used by one instance and an instance is trying to bring a rollback


generated on the server at failure time.Existence of a trace file may suggest an Oracle internal error


解决方法：一般来说出现这个错误我们本身是无法解决的，只有从提高系统本身各方面来解决这个内部问题，如增加硬件
ORA-03113：end-of-file on communication channel
access to it.

一个报错例子如下：
相应的英文如下：

解决方法：1>.检查是否有服进程不正常死机，可从alert.log得知
产生原因：这是由于装载的表或视图不存在，多半是CATEXP.SQL还没有运行，无法执行Export视图,如果CATEXP.SQL已经运

The spelling of the table or view name.
Incorrectly restored files（错误的重建文件）

设备，调整系统性能，使用OPS（当然OPS从某种意义上说并不是一种好的解决方式）等。ORA-600错误的第一个变量用于标
ORA-01598:rollback segment “name” is not online

that requires the assistance of customer support.
segment online that is already in use.
File corruption(文件太老)
Time-outs（超时）
Action:Check the status of the rollback segment in DBA_ROLLBACK_SEGS.
2>.检查sql*Net Driver是否连接到ORACLE可执行程序

ORA-00600: internal error code, arguments: [1237], [], [], [], [], [], [], []
table the application tried to access does not exist in the database,or the application does not have
产生原因：通讯不正常结束，从而导致通讯通道终止

行，则可能是版本错误。
Cause:An unexpected end-of-file was processed on the communication channel.The problem could not be


相应的英文如下：
ORA-1636: rollback segment “name” is already online
Cause:The rollback segment was taken offline either manually or by SMON.
Contact the database administrator if the table needs to be created or if user or application priviledes
Action:If this message occurs during a commection attempt,check the setup files for the appropriate Net8
解决方法：因为Import和Export共享的一些视图是通过运行CATEXP.SQL来装载的（它们具有相同的视图），并不生成单独


communication vehicle,that is,the network or server machine went down.
相应的英文如下：


Action:Check that the values set in the initialization parameter file for parameters

That an existing table or view name exists.





记代码中错误的位置（代码中的每个部分的第一变量都不一样），从第二个到第五个变量显示附加信息，告诉OSS代码在哪


4>.检查同一个网上是否有两个同样名字的节点
Also, if attempting to access a table or view in another schema,make certain thecorrect schema is
ROLLBACK_SEGMENTS,ROLLBACK_SEGMENT_INITIAL,a

3>.检查服务器网络是否正常，如网络不通或不稳定等
里出现了错误。

产生原因：这种错误通常为ORACLE的内部错误，只对OSS和ORACLE开发有用。ORA-600的错误经常伴随跟踪文件的状态转储
