二话不说,上sql

排查经过如下

1.查询SQL监视(DBA)

select dbms_sqltune.report_sql_monitor(type=>'TEXT', sql_id=>'fw40xhr1skg98',report_level=>'ALL') monitor_report from dual;

结果:

2.定位问题(DBA)

从以上执行计划定位到对象SELECT_INDEX_NO1_PART的cost最大,走过
查清楚该对象是什么

select * from dba_objects where object_name='SELECT_INDEX_NO1_PART';

72556abb_82b7_496a_8e8f_aa4cf37d2753

发现是索引,查下是哪个表的

select * from dba_indexes where index_name ='SELECT_INDEX_NO1_PART';

c3f3d2a5_0eec_426b_99b8_61420423e489

复制表名FIN_ADM.T5001_TASK,在plsql中右键->查询
06fc8689_0865_4aa8_9769_853f1d273ec6

根据执行计划的嫌疑T5001_TASK,发现问题出现在该表的索引,尝试着收集一下统计信息,详见Oracle执行计划,测试一下执行速度,依旧很慢。
之前一位大师说过,调优就像打太极,急不得!略焦虑的我强忍着迫切的心情出去吃了个苹果,静下心来,仔细对比一下sql文本对应位置与所查索引的字段,仔细阅读过滤条件,发现AND T5001_TASK.FLIGHT_DATE + 90 > TRUNC(date'2019-6-20')处有大嫌疑,+90可能会导致查询结果集变大,从而走索引效率反而可能没有全表扫描高。实践如下。

3.解决方案

在对应位置加入/*+ full(T5001_TASK) */,sql如下

SELECT N.DEP_CODE,
       N.P_CODE,
       N.AC_TYPE_MACRO,
       nvl(T.UPDOWN, 0) + nvl(U.UPDOWN, 0) UP,
