根据trc文件提示，ORA-00600 [kokbcvb1] 是如下SQL引起的：

  MERGE INTO DW_BILL T1
  USING (SELECT B.HIS_ID,
                SUM(CASE
                      WHEN B.REJECT_MONEY >= B.CAN_REJECT_MONEY THEN

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

Merge Query Failed with Ora-00600: [Kokbcvb1] (文档 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 Patch 8651671 and Patch 5308497 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This could possibly be due to Bug 9471103 MERGE QUERY FAILED WITH ORA-600 [KOKBCVB1]  which was closed as duplicate of unpublished Bug 9757249 ORA-600 [KOKBCVB1]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 The fix for Unpublished Bug 9757249 is included in 11.2.0.2 and above.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 Patch 9757249 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.

从提取到的报错信息，与bug 9471103吻合，处理方法是：应用补丁包patch 9757249或者升级数据库版本到11.2.0.2以上
