create temp table as from occur ora-600 处理一例

用户某个ETL 数据库在处理一个临时表时候出现建表失败并遭遇 ORA-00600 报错，具体信息如下：

Oracle Database  11.2.0.4.0 on suse linux 11 sp3

create table tmp_5302_ins_prf_agtlevel_3b as
 select distinct a.company_cd, a.agent_level, a.INSURED_RNG_TYPE, b.INSURED_RNG_SUB_TYPE, b.INSURED_RNG_VALUE, a.minus_NOI
 from

 from qs.tmp_5302_ins_prf_agtlevel_2 a where INSURED_RNG_TYPE='TENURE_RNG'
 group by company_cd, agent_level, INSURED_RNG_TYPE, NULL
 ) a,

from qs.tmp_5302_ins_prf_agtlevel_2 a where INSURED_RNG_VALUE<>'z) Total' and INSURED_RNG_TYPE='TENURE_RNG')
where get_ind=1
 ) b
where a.company_cd=b.company_cd and a.agent_level=b.agent_level ;
error info:
ORA-00600: internal error code [rwoirw: check ret val], [], [], [], [], [], [], [], [], [], [], []

官方对该bug 的描述如下，并提供了2种解决途径：

Refrence：Bug 14275161 - ORA-600 [rwoirw: check ret val] on CTAS with predicate move around (Doc ID 14275161.8)

第一种是升级到12.1（当前阶段显然不靠谱）
第二种方法：通过设置隐含参数 _pred_move_around 为false来绕过该错误：

Description：A CTAS (Create table as select) operation undergoing predicate move around may fail during execution with an ORA-600 [rwoirw: check ret val] Workaround Disable predicate move around before executing the CTAS. eg:  alter session set "_pred_move_around"=FALSE;

最终由于业务数据库中诸如此类的临时表创建非常的频繁，所以只能从oracle support 拿到该bug 的one-off patch 14275161补丁解决,问题消失。

该patch需要用最新的OPatch 工具apply，具体OPatch 的更新和使用见：OPatch Tool upgrade and using
