修改AWR報告裡面的topnsql 引數
檢視： dba_hist_wr_control
修改awr相關引數 ，本次主要修改topnsql ，該值預設是30。
[email protected]>exec dbms_workload_repository.modify_snapshot_settings(topnsql => 100);
PL/SQL 過程已成功完成。
[email protected]>exec dbms_workload_repository.modify_snapshot_settings(topnsql => 10);
BEGIN dbms_workload_repository.modify_snapshot_settings(topnsql => 10); END;
