Oracle常见错误代码的分析与解决四

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(系统状态和进程状态),系统状态存储将包括ORACLE RDBMS持有的当前对象的信息,进程状态转储则将显示特殊进程持有的对象,当进程符合了某错误条件时,经常是由于一些信息取自它持有的一个块,如果我们知道这些错误进程持有的块,就容易跟踪问题的来源。

  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代码在哪里出现了错误。

  一个报错例子如下:

  ORA-00600: internal error code, arguments: [1237], [], [], [], [], [], [], []

  相应的英文如下:

  Cause:This is a catchall internal error message for Oracle program exceptions.It indicates that a process has met a low-level,unexpected condition.Various causes of this message include:

  Time-outs(超时)

  File corruption(文件太老)

  Failed data checks in memory(内存检索失败)

  Hardware,memory,or I/O errors(硬件、内存或者磁盘错误)

  Incorrectly restored files(错误的重建文件)

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

  产生原因:通讯不正常结束,从而导致通讯通道终止

  解决方法:1>.检查是否有服进程不正常死机,可从alert.log得知

  2>.检查sql*Net Driver是否连接到ORACLE可执行程序

  3>.检查服务器网络是否正常,如网络不通或不稳定等

  4>.检查同一个网上是否有两个同样名字的节点

  5>.检查同一个网上是否有重复的IP地址

  相应的英文如下:

  Cause:An unexpected end-of-file was processed on the communication channel.The problem could not be handled by the Net8,two task,software.This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally,or if there is a physical failure of the interprocess communication vehicle,that is,the network or server machine went down.

  Action:If this message occurs during a commection attempt,check the setup files for the appropriate Net8 driver and confirm Net8 software is correctly installed on the server.If the message occurs after a connection is well established,and the error is not due to a physical failure,check if a trace file was generated on the server at failure time.Existence of a trace file may suggest an Oracle internal error that requires the assistance of customer support.

  ORA-00942:table or view does not exist
