数据库版本：Oracle 11.2.0.1.0
数据库服务器操作系统：Windows server 2008
问题现象：业务人员在前台执行某些查询操作时，报错ORA-00600: 内部错误代码, 参数: [19004]；
解决方案：查看alert警告日志，查找对应的trace文件，找到触发此bug的sql语句如下：
----- Current SQL Statement for this session (sql_id=.......) -----
SELECT *
FROM TAB_1
WHERE COL_1 in (select id from TAB_2)
and COL_2 in (:1, :2)
and COL_3 in
('null', 'null', 'null', 'null', 'null', 'null', 'null')
order by COL_4,COL_5;
根据MOS查看，此错误匹配多个BUG，都是由于表错误的统计信息和列的统计直方图触发此BUG，可以删除SQL中对应表的统计信息和统计直方图临时解决此问题，或者直接升级数据库跳过此BUG；
删除统计信息方法如下：
散打狼执行了这面这条语句后就可以了
---ANALYZE TABLE TAB_1 DELETE STATISTICS;
---ANALYZE TABLE TAB_2 DELETE STATISTICS;
SQL> execute dbms_stats.delete_table_stats(ownname=>'USER_NAME',tabname=>'TAB_1');
SQL> execute dbms_stats.delete_table_stats(ownname=>'USER_NAME',tabname=>'TAB_2');
SQL> execute dbms_stats.lock_table_stats(ownname=>'USER_NAME',tabname=>'TAB_1');
SQL> execute dbms_stats.lock_table_stats(ownname=>'USER_NAME',tabname=>'TAB_2');
---SQL> execute dbms_stats.unlock_table_stats(ownname=>'USER_NAME',tabname=>'TAB_1');
---SQL> execute dbms_stats.unlock_table_stats(ownname=>'USER_NAME',tabname=>'TAB_2');
删除表统计信息可能会生成错误的执行计划，影响SQL执行效率；
可以适当调大动态取样级别；
SQL> show parameter optimizer_dynamic_sampling
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
optimizer_dynamic_sampling integer 4
