根据trc文件提示，ORA-00600 [kokbcvb1] 是如下SQL引起的：
MERGE INTO DW_BILL T1

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.
This could possibly be due to Bug 9471103 MERGE QUERY FAILED WITH ORA-600 [KOKBCVB1] which was closed as duplicate of unpublished Bug 9757249 ORA-600 [KOKBCVB1]
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
