給對方打電話，詢問情況，得知開發說以前跑的比現在快
我讓對方跑select * from table(dbms_xplan.display_awr('0ah5a8dbk28fh'),null,null,'advanced'); 並將內容發給我
其中存在三個執行計劃， cost 分別有三個，當前跑的這個是其中cost最大的那個
第一、我不在現場
第二、現在沒時間，也沒辦法詳細優化
所以我選擇的方案，就是通過coe_xfr_sql_profile.sql 來將執行計劃綁定為cost最小的那個!
後來對方領導決定先不kill，因為我和對方說，這裡是DML操作，回滾時間會比較長。
這裡反應出了問題，首先開發連select的速度都沒測，就直接insert，真是。。而且，再弱也應該知道開並行吧?這裡也沒有開並行
等周二詳細優化的時候，思路如下：
1、先檢查統計信息，並檢查這個SQL產生三個執行計劃的主要原因
2、將union all 拆開，分別優化每個SQL(如果能用with as 嘗試運用)
3、優化好查詢速度之後 開並行跑。這裡注意，看並行DML 要打開session級別的並行DML
未完待續……
