20160522-ORA-00600: 内部错误代码, 参数: [19004]

说明:

本文整理自我的ITPUB博客，链接如下:

https://blog.itpub.net/29785807/viewspace-2104830/

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：

---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
