ORACLE SQL调优之执行计划与隐藏参数_complex_view_merging
生活随笔
收集整理的這篇文章主要介紹了
ORACLE SQL调优之执行计划与隐藏参数_complex_view_merging
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
最近，赤峰windows 版的11.2.0.3的oracle數據庫出現一條sql語句執行非常慢，需要1天的時間還出不來，但是觀察服務器的IO和CPU都是很空閑，并且將
該sql語句涉及的對象全部導出，然后分別導入其他機器oracle數據庫與出現性能問題的數據庫，發現其他機器數據庫執行非常快而問題數據庫依舊很慢。嘗試
收集方案及表的統計信息后，再次執行sql語句還是沒有改善，在問題處理的過程中，注意到一個很明顯的問題，就是不管收集統計信息還是給sql加并行、使
用強制sql走hash，其執行計劃都是原來的嵌套循環執行計劃并且出現view字樣。最終定位到數據庫啟動初始化參數_complex_view_merging。

同一條sql語句不通實例執行下的執行計劃做對比，除了性能問題實例中該sql執行計劃出現view、nestloop嵌套循環外、執行時間特別長外，就是
出現性能問題的實例中的sql語句執行計劃里還出現了：OPT_PARAM('_complex_view_merging' 'false')，于是生成pfile查看該實例的參數設置

于是嘗試修改隱藏參數，執行
alter system set "_complex_view_merging"=TRUE scope=both;
alter system set "_simple_view_merging"=TRUE scope=both;
修改完成重啟數據庫服務后，問題sql執行計劃恢復正常，sql正常執行8s就出結果。
該sql語句涉及的對象全部導出，然后分別導入其他機器oracle數據庫與出現性能問題的數據庫，發現其他機器數據庫執行非常快而問題數據庫依舊很慢。嘗試
收集方案及表的統計信息后，再次執行sql語句還是沒有改善，在問題處理的過程中，注意到一個很明顯的問題，就是不管收集統計信息還是給sql加并行、使
用強制sql走hash，其執行計劃都是原來的嵌套循環執行計劃并且出現view字樣。最終定位到數據庫啟動初始化參數_complex_view_merging。

同一條sql語句不通實例執行下的執行計劃做對比，除了性能問題實例中該sql執行計劃出現view、nestloop嵌套循環外、執行時間特別長外，就是
出現性能問題的實例中的sql語句執行計劃里還出現了：OPT_PARAM('_complex_view_merging' 'false')，于是生成pfile查看該實例的參數設置
pfile:
orclnew.__db_cache_size=36775657472
orclnew.__java_pool_size=134217728
orclnew.__large_pool_size=134217728
orclnew.__oracle_base='E:\app\Administrator'#ORACLE_BASE set from environment
orclnew.__pga_aggregate_target=13824425984
orclnew.__sga_target=41339060224
orclnew.__shared_io_pool_size=0
orclnew.__shared_pool_size=3892314112
orclnew.__streams_pool_size=134217728
*._complex_view_merging=FALSE
*._optimizer_use_feedback=FALSE
*._simple_view_merging=FALSE
*.audit_file_dest='E:\app\Administrator\admin\orclnew\adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.control_files='E:\APP\ADMINISTRATOR\ORADATA\ORCLNEW\CONTROL01.CTL','E:\APP\ADMINISTRATOR\FAST_RECOVERY_AREA\ORCLNEW\CONTROL02.CTL'#Restore Controlfile
*.db_block_size=8192
*.db_domain=''
*.db_name='orclnew'
*.db_recovery_file_dest='E:\app\Administrator\fast_recovery_area'
*.db_recovery_file_dest_size=4322230272
*.deferred_segment_creation=FALSE
*.diagnostic_dest='E:\app\Administrator'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclnewXDB)'
*.log_archive_dest_1='location=D:\orclnew\archivelog'
*.log_archive_format='arch_%r_%t_%s.arc'
*.open_cursors=300
*.pga_aggregate_target=13740539904
*.processes=500
*.remote_login_passwordfile='EXCLUSIVE'
*.session_cached_cursors=3000
*.sga_target=41221619712
*.undo_tablespace='UNDOTBS1'
于是嘗試修改隱藏參數，執行
alter system set "_complex_view_merging"=TRUE scope=both;
alter system set "_simple_view_merging"=TRUE scope=both;
修改完成重啟數據庫服務后，問題sql執行計劃恢復正常，sql正常執行8s就出結果。
總結
以上是生活随笔為你收集整理的ORACLE SQL调优之执行计划与隐藏参数_complex_view_merging的全部內容，希望文章能夠幫你解決所遇到的問題。
