주의
Vacuuming removes obsolete event and notification data from the application database. For more information about the vacuuming process, see 사용되지 않는 응용 프로그램 데이터 제거.
Vacuuming schedules cannot overlap. If schedules overlap, Notification Services stops the earlier vacuuming process before the later one starts.
If you omit the Vacuum element and its child elements, the vacuuming process does not run and obsolete data is not automatically removed from the application database.
