Osservazioni
Vacuuming removes obsolete event and notification data from the application database. For more information about the vacuuming process, see Rimozione di dati dell'applicazione obsoleti.
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.
Esempio
The following example shows how to define a data retention age of three days (P3DT00H00M00S) and to configure the vacuuming process to run from 3:00 A.M. to 5:00 A.M. (UTC) and from 11:00 P.M. to 1:00 A.M. (UTC) every day.
