ORA-00600: internal error code, arguments: [kgantc_1]错误排查记录(原创)

操作系统：AIX 6.1 数据库环境：RAC 10.2.0.5

2011/10 /08 16:33左右，节点1出现的ORA-00600错误，产生dump文件为5M多的 zgscdb1_ora_26739166.trc ，2011/10/09 15:43左右，节点二出现ORA-00600错误，dump文件为 159K的zgscdb2_ora_35651868.trc
节点1：
这个错误是由于取消当前操作所引发。
Sat Oct 08 16:33:46 GMT+08:00 2011Errors in file /oracle10g/app/oracle/admin/zgscdb/udump/zgscdb1_ora_26739166.trc:
ORA-00600: internal error code, arguments: [kgantc_1], [0], [1], [], [], [], [], []
ORA-00604: error occurred at recursive SQL level 1
ORA-01013: user requested cancel of current operation
根据错误信息和错误的发生时间，基本上可以确定，问题是由于取消当前操作引起的，下面检查一下详细信息，查看当前执行的操作是什么。
Trace开头部分内容如下：
*** 2011-10-08 16:33:45.573
*** ACTION NAME:(Test Window - Script for procedu) 2011-10-08 16:33:45.565

ORA-00600: internal error code, arguments: [kgantc_1], [0], [1], [], [], [], [], []
ORA-00604: error occurred at recursive SQL level 1
ORA-01013: user requested cancel of current operation
从这里可以看到错误会话是通过PL/SQL Developer连接到数据库的，下面是出错SQL部分：
Current SQL statement for this session:
begin
  -- Call the procedure
  p_fp_dk_sfxx(inwspzxh => :inwspzxh,
               errcode => :errcode,
               errmean => :errmean);
end;
从这里只能看出错误的发生与用户取消操作有关，调用的PL/SQL包本身并没有什么异常。
 O/S info: user: Administrator, term: FZLTAX-SK-DL, ospid: 844:5076, machine: SK\FZLTAX-SK-DL
              program: plsqldev.exe    application name: PL/SQL Developer
这 是开发人员通过windows平台，使用PL/SQL Developer连接数据库做了PL/SQL代码测试，终端名称为FZLTAX-SK-DL，开 发人员运行此代码过程中取消了该操作，触发ORA-00600。搜索METALINK  ORA-00600 [kgantc_1]，并没有发现什么有价值的线索，发现有一个与此相类似的问题，此错误发生的ORACLE版本范围比较大，是一个未发布的bug，在11.2版本以后才修补，10.2.0.5是 10G最后一个补丁，出现类似的bug也属正常：
Applies to:
Oracle Server - Enterprise Edition - Version: 8.1.7.0 to 11.1.0.7
This problem can occur on any platform.
Symptoms
A user interrupted the session while in the process of creating the connection - this is seen in the alert.log as something like:
ORA-00600: internal error code, arguments: [ttcgcshnd-2], [0], [], [], [], [], [], []
ORA-01013: user requested cancel of current operation
The instance continues to operate normally after the error.
Cause
The root cause is a problem handling the client interrupt (Ctrl-C) during connection handshake - this has been discussed in non-published bug:3210738.
Solution
The issue is completely harmless and can be safely ignored.
From 11.2 a fix has been implemented that will cause the client to raise an ORA-28547 (or an ORA-3106 if the client is pre-11.2). This has been implemented via non-published bug:6859408
References
在当前的例子中，是可能由于错误是ORA-1031，是用户取消造成的，相对比较特殊，Oracle没有正确的捕获和处理，从而导致了这一系列Oracle内部错误的出现。
总的来说，这个错误出现的概率很小，且本身没有什么维护。如有特殊疑问，也可以与开发人员进行沟通。
节点2：
仍然是由于取消当前操作所引发。

代码如下:

另外在搜索ora-600 kgantc_1错误时发现了由于没有debug权限导致该错误的例子，这里也一并记录下来，以便日后查看。

客户的数据库版本是11.2.0.2，而metalink上并没有这么新的版本的说明。不过Oracle的官方记录了类似情况，由于缺少权限，导致PL/SQL出现大量错误，从而最终引发了ORA-600(kgantc_1)的错误。
观察除了ORA-600(kgantc_1)以外的错误信息，问题多半是由于“PL/SQL: 用户定义的异常错误未得到处理”所致。和客户的DBA沟通，确认问题发生时刻，有开发程序员通过PLSQL DEVELOPER工具的DEBUG功能来执行PL/SQL代码。
显然是由于DEBUG过程中，出现了自定义的异常没有捕获的情况，从而引发了这个600错误。而解决问题的方法也很简单，如果不能避免DEBUG程序，那么起码在DEBUG的时候，确保捕获了所有的异常，并不会再次抛出。

Trace file also shows the following errors
Probe:S:debug_loop: exception 1: ORA-01031: insufficient privilege
Other internal errors that may accompany the ora-1031 and ora-6512 are:
ORA-07445: exception encountered: core dump [pfrdmp()+4] [SIGSEGV] [Address not mapped to object] [0x0000000B0] [] []

ORA-00600: internal error code, arguments: [kgantc_1], [0], [1], [], [], [], [], []
Cause
User does not have sufficient privileges for debugging PL/SQL
Bug:4640115 was filed to address the internal errors exposed when the accurate error is the ora-1031
Bug:4640115 was still in progress at the time this note was written
Solution
1. Connect in SQL*Plus as a DBA/SYSDBA
2. grant the privilege DEBUG CONNECT SESSION to your user:
   SQL> GRANT DEBUG CONNECT SESSION to <user> ;
