使用方法
ASH関連情報を取得するには、oceanbase.GV$ACTIVE_SESSION_HISTORY ビューをクエリする必要があります。
例
サーバーの出力を有効にします。
obclient> SET SERVEROUTPUT ON;
ASH_REPORT を呼び出し、診断する開始時間と終了時間を入力します。実行後、ASHレポート情報が画面上に表示されます。
obclient> CALL DBMS_WORKLOAD_REPOSITORY.ASH_REPORT(
TO_DATE('2023-12-18 21:19:00', 'yyyy-MM-dd HH24:mi:ss'),TO_DATE('2023-12-19 13:58:02', 'yyyy-MM-dd HH24:mi:ss') );
