Vacuuming removes older event and notification data from the application database. For more information about the vacuuming process, see 配置数据删除操作.

The vacuuming process runs daily at the specified time(s) for the specified duration.

Vacuuming schedules cannot overlap. If schedules overlap, Notification Services stops the earlier vacuuming process before the later one starts.

The following example shows a populated VacuumSchedule element that specifies that vacuuming runs from 1:00 A.M. to 4:00 A.M. (UTC) every day.

<VacuumSchedule>
    <Schedule>
        <StartTime>01:00:00</StartTime>
        <Duration>P0DT03H00M00S</Duration>
    </Schedule>
</VacuumSchedule>
