ORA-00600: internal error code, arguments: [qkabix], [0], [], [], [], [], [], []
1、阅读trace文件，定位问题SQL
2、查看执行计划时发现 有位图索引的访问路径，但经过检查发现相关对象并没有位图索引
3、查看MOS，定位文档
4、通过修改隐含参数规避：sql> alter system set "_b_tree_bitmap_plans"=false;

SYMPTOMS
The following internal error is reported in the alert log:
    ORA-00600: internal error code, arguments: [qkabix], [0], [], [], [], [], [], []

The error is reported running a Select statement.

The call stack looks like:
   qkabix qkaix qkatab qkajoi qkaqkn qkadrv opitca kksFullTypeCheck rpiswu2 kksSetBindType kksfbc
   kkspfda kpodny kpoal8
CAUSE
The problem could be related to a CBO ( Cost Based Optimizer ) issue when a query uses a bitmap access paths for b-tree indexes.
It was reported in Bug 5945798 but could not be confirmed.
SOLUTION
One possible workaround to avoid the error is to disable the optimizer to produce bitmap plans for B-Tree indexes, even if there is no bitmap index anywhere in sight.

- at session level:
     sql> alter session set "_b_tree_bitmap_plans"=false;

- or at system level:
     sql> alter system set "_b_tree_bitmap_plans"=false;

- or in the init.ora/spfile:
     _b_tree_bitmap_plans = false

About this "_b_tree_bitmap_plans" parameter.
===============================
_B_TREE_BITMAP_PLANS enables creation of interim bitmap representation for tables in a query with only binary index(es). Default value is FALSE in Oracle 8i and TRUE in Oracle 9i and above.
