ORA-00600: 内部错误代码, 参数: [qctcte1]

【情景再现】

生产环境，JAVA程序某功能报错：

ORA-00600: 内部错误代码, 参数: [qctcte1], [0], [], [], [], [], [], []

【问题排查】

1.检查Oracle的alert日志，发现如下行：

Tue Sep 17 17:11:04 2013
Errors in file /oracle/admin/kyy/udump/kyy_ora_5613.trc:
ORA-00600: 内部错误代码, 参数: [qctcte1], [0], [], [], [], [], [], []

2.继续追踪kyy_ora_5613.trc，发现如下行：

*** 2013-09-17 17:11:04.712
ksedmp: internal or fatal error
ORA-00600: 内部错误代码, 参数: [qctcte1], [0], [], [], [], [], [], []
Current SQL statement for this session:
select ……  from …… ORDER BY ……

3.在开发环境和生产环境测试问题SQL：

/* Formatted on 2013/09/25 10:42 (Formatter Plus v4.8.8) */
SELECT   a.formid, flowtempletno, laststep, waitrunsetp, status,
         lastoperperson, lastopertime, createpersonid, createpersonname,
         createtime, lastmodifypersonid, lastmodifytime, infodep
    FROM bg_forminfo a
   WHERE moduleno = :1
     AND formid IN (
            SELECT DISTINCT a.formid
                       FROM bg_forminfo a,
                            bg_flowstep b,
                            v_bg_flowuser d,
                            bg_flowtemplet e
                      WHERE a.status = :2
                        AND e.moduleno = :3
                        AND a.flowtempletno = e.flowtempletno
                        AND a.formid = b.formid
                        AND b.stepno = a.waitrunsetp
                        AND b.roleno = d.roleno
                        AND b.managescope = d.managescope
                        AND d.personid = :4
                        AND a.waitrunsetp != 1)
ORDER BY (SELECT columvalue
            FROM bg_forminfodetail b
           WHERE formid = a.formid AND columnen = 'gds_ycsj') DESC,
         (SELECT columvalue
            FROM bg_forminfodetail b
           WHERE formid = a.formid AND columnen = 'gds_lxrxm')

结果如下：

Oracle版本	OS版本	执行结果
Oracle 10.2.0.1 64bit	CentOS 5.3 64bit	PASS
Oracle 10.2.0.4 32bit	Windows 2003 Enterprise 32bit	PASS
Oracle 10.2.0.4 64bit	Ignite-UX revision C.7.9.254 （ia64 hp server rx6600）	ERROR

4.分析SQL，查找报错原因：

根据官方对于ORA-00600 [qctcte1]的解释，出错原因有可能是ORDER BY 语句，

修改ORDER BY 中的排序列，执行通过。

【问题回顾】

遇到ORA-00600问题，

开始以为Oracle的参数设置有误，对比开发和生产数据库的版本和参数未发现问题（cursor_sharing）；

接着怀疑程序连接数据库的classes12.jar，生产和开发使用的都是10.2.0.1版本的classes12.jar，

最后根据Oracle官方解释，问题定位在SQL的ORDER BY中。
