Oracle SPM(SQL Performance Management)是一种用于监控和管理SQL性能的工具,可帮助识别和解决性能问题。以下是利用Oracle SPM进行SQL性能监控的步骤:
ALTER SYSTEM SET CONTROL_MANAGEMENT_PACK_ACCESS = ‘DIAGNOSTIC+TUNING’ SCOPE = BOTH;
BEGIN DBMS_SPM.CREATE_SQL_PLAN_BASELINE(sql_handle => ‘SQL_HANDLE’, plan_name => ‘PLAN_NAME’, fixed => ‘YES’); END;
BEGIN DBMS_SPM.LOAD_PLAN_FROM_CURSOR_CACHE(sql_id => ‘SQL_ID’); END;
BEGIN DBMS_SPM.SPM_EVOLVE_SQL_PLAN_BASELINE(sql_handle => ‘SQL_HANDLE’, time_limit => 60, verify => ‘YES’); END;
通过以上步骤,您可以利用Oracle SPM进行SQL性能监控,帮助识别和解决SQL性能问题,提高数据库性能和可靠性。
