根據trc檔案提示，ORA-00600 [kokbcvb1] 是如下SQL引起的：

  MERGE INTO DW_BILL T1

關於ORA-00600 [kokbcvb1] ，oracle 官方有篇文件（文件 ID 1182535.1）提到是Bug 9471103 引起的：

Merge Query Failed with Ora-00600: [Kokbcvb1] (文件 ID 1182535.1)

APPLIES TO:                                                                               

Oracle Database - Enterprise Edition - Version 10.2.0.4 to 11.2.0.2.0 [Release 10.2 to 11.2]
Information in this document applies to any platform.
***Checked for relevance on 29-Feb-2012*** 

SYMPTOMS                                                                                

A merge query failed with the error below:

ORA-600: internal error code, arguments: [kokbcvb1], [], [], [], [], []

For example :

merge into X USING (select a col1,'B' col2,3 col3,...

Even with  and  applied, the problem still reproduces. 

When "_optimizer_push_pred_cost_based"=false; the statement fails with

ORA-2070: database does not support antijoin

With "_subquery_pruning_enabled"=false; statement finishes with

0 rows merged.

CAUSE                                                                                  

This could possibly be due to  MERGE QUERY FAILED WITH ORA-600 [KOKBCVB1]  which was closed as duplicate of unpublished Bug 9757249 ORA-600 [KOKBCVB1]

SOLUTION

1. The fix for Unpublished Bug 9757249 is included in 11.2.0.2 and above. Therefore, please upgrade to 11.2.0.2 or higher.
OR
2. Apply one off  if available on My Oracle Support for your Oracle version and platform. If a patch is not available, please log a Service Request with Oracle Support to assist you.
