ORACLE 11g 使用ROWNUM完美解决ORA-00600:内部错误代码

前端之家收集整理的这篇文章主要介绍了ORACLE 11g 使用ROWNUM完美解决ORA-00600:内部错误代码前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

1ORA-00600:内部错误代码

Oracle从11.2.0.1升级到11.2.0.4,开发人员报告说一个job运行失败,调试有报错信息,ORA-00600:内部错误代码,参数:[rwoirw: check ret val],[],[],[],ORA-06512:…,如下图所示:


C:\pic\oracle\2017040501.png

查看这个2000行的包体,查看到454行代码是一个create table as的很长的sql,如下所示:

/*===========================================================================*/
  /*构建ads_amp_pd_ma_merchant_sale表*/
/*===========================================================================*/
  PROCEDURE ads_amp_pd_ma_merchant_sale AS
    v_createsql varchar2(32767);
  BEGIN
    PKG_COMMON.drop_table('ads_amp_pd_ma_merchant_sale');
 
    v_createsql := '
    create table ads_amp_pd_ma_merchant_sale as
    (select
      --0 as ID,PKG_ADS_AMP_PD.PARTNER_ID as PARTNER_ID,0 as PROJECT_ID,0 as CONT_ID,zjwgsals.bis_shop_name as BRAND_NAME,zjwgsals.sales_money as SALE_AMOUNT,0 as BUDGET_AMOUNT,decode(zjwgsals.rent_square,round(zjwgsals.sales_money / zjwgsals.rent_square,2)) as PERFORMANCE_VALUE,decode(zjwgsals.sales_money,round(zjwgsals.must_zj / zjwgsals.sales_money,2)) as RENT_SALE_RATE,decode(zjwgsals.sort_name_root,''超市'',''100'',''影院'',''200'',''百货'',''300'',''服装'',''400'',''儿童'',''500'',''餐饮'',''600'',''配套'',''700'',''800'') as COMMERCIAL_TYPE,zjwgsals.sort_name_root as COMMERCIAL_TYPE_NAME,zjwgsals.YEAR as YEAR,zjwgsals.MONTH as MONTH,zjwgsals.qz_year_month as DUTY_MONTH,''0'' as IS_DEL,sysdate as CREATE_DATE,--null as UPDATE_DATE,PKG_ADS_AMP_PD.USER_ID as CREATER_ID,--null as UPDATER_ID,zjwgsals.bis_project_id as OUT_PROJECT_ID,zjwgsals.bis_cont_id as OUT_CONTRACT_ID,round(zjwgsals.sales_money * nvl(mustrent.royalty_ratio,0) / 100 / 30.42,2) as RENT_PER_DAY,0) / 100,2) as RENT_PER_MONTH
    from
      ads_amp_pd_ma_contract cont
    inner join
      (select
        a.*,to_number(substr(qz_year_month,1,4)) as YEAR,6,2)) as MONTH
      from dws_pd_cont_zjwgsals_1m a
      where dt = PKG_COMMON.YESTERDAY_YYYYMMDD
        and a.status_cd not in (''3'',''5'')
        and a.sals_data_flg = ''1''
      ) zjwgsals
    on cont.OUT_PROJECT_ID = zjwgsals.bis_project_id and cont.OUT_CONTRACT_ID = zjwgsals.bis_cont_id
    left outer join
      --提成百分比
      (select
        bis_cont_id,year,royalty_ratio,guaranteed_money
      from ods_pd_bis_must_rent
      where dt = PKG_COMMON.YESTERDAY_YYYYMMDD
      ) mustrent
    on zjwgsals.bis_cont_id = mustrent.bis_cont_id and (to_number(zjwgsals.YEAR) - to_number(to_char(cont.START_DATE,''yyyy'')) + 1) = mustrent.year
    --TODO:
    where zjwgsals.bis_project_id in (''6D7E1C7AFAFB43E986670A81CF444235'',''402834702db81ec3012dbca135f20c6a'')
    )';
    executeimmediate v_createsql;
    COMMIT;
  END;



2,官方的解决途径不是最佳方案

是动态sql执行的,创建一个表出错的问题,在11.2.0.1的version里面是ok的,到了11.2.0.4就出问题了,google了下,说是11.2.0.4的一个bug。

官方对该bug的描述如下,并提供了2解决途径:

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

第一种是升级12.1

--》这个刚升级完11.2.0.4再升级到12.1显然不太合适,而且万一到了12.1,又有新的bug出现,那就比较麻烦了。

第二种方法:通过设置隐含参数 _pred_move_around false来绕过该错误

--》这个也尝试过了,不行,存储过程的动态sql里面,添加 altersystem set _pred_move_around =false;后报下面的错误出来:

sql> call PKG_ADS_AMP_PD.build();

call PKG_ADS_AMP_PD.build()

ORA-04068: existing state of packages has been discarded

ORA-04061: existing state of package body "DW.PKG_ADS_AMP_PD" has been invalidated

ORA-04065: not executed,altered or dropped package body "DW.PKG_ADS_AMP_PD"

sql>

所以说以上两种办法都不太可行,把create sql从动态存储过程里面拿出来,单独在11.2.0.4上面执行,是报错的,而且报错一模一样;突然想到难道是临时表的数量太多了导致的?然后马上尝试后面添加rownum < 100; 手动执行create sql语句结果成功了。

3,使用ROWNUM完美解决

思考了下,也许11.2.0.4里面对create tablexxx as select …. From …的限制比较严格(或者也许就是真的一个bug?),意味着在不知道后面的select … from …的总体数量的情况下或者数量已经超过了oracle的默认值比如1000这样,会提示ORA-00600的错误。按照这个思路我查询出来select … from ..的总数量,在后面加上and rownum<100000;,再次执行存储过程,哎,天降奇瑞,成功了。

然后再发散思维下,万一下回select的总数量超过100000了呢,那咋办,总不能每次都去select count(1) from …然后再create吧。按照测试的边界值理论,一个最大值ok了,那我尝试下最小值呢,用and rownum>-1;(因为有可能select 出来空记录)呢?尝试了下,存储过程执行成功了,and rownum>-1那么最终改写的存储过程中的sql如下:

@H_403_172@/*===========================================================================*/ /*构建ads_amp_pd_ma_mercha,nt_sale表*/ /*===========================================================================*/ PROCEDURE ads_amp_pd_ma_merchant_sale AS v_createsql varchar2(32767); BEGIN PKG_COMMON.drop_table('ads_amp_pd_ma_merchant_sale'); v_createsql := ' create table ads_amp_pd_ma_merchant_sale as (select --0 as ID,''402834702db81ec3012dbca135f20c6a'') )' and rownum>-1; executeimmediate v_createsql; COMMIT; END;


OK,到此,问题完美解决,不改程序代码,不改系统参数,不用重启db,只需要在存储过程create语句where条件后面加上简单的and rownum>-1就搞定了。
