1、閱讀trace文件，定位問題SQL

2、查看執行計劃時發現 有位圖索引的訪問路徑，但經過檢查發現相關對象並沒有位圖索引

3、查看MOS，定位文檔

4、通過修改隱含參數規避：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.
