The PurgingService component /atg/epub/purge/PurgingService
can be configured to start purges at regular intervals or on specific dates. By default, the scheduler
property is set to /atg/dynamo/service/Scheduler
. As with other ATG services, you can set the schedule
property as follows:
PeriodicSchedule and RelativeSchedule, which specify to run the purge at regular intervals, with a start time relative to the current time. For example, the following
schedule
setting specifies to run the PurgingService every 60 days, starting in two hours:schedule=every 60 days in 2 hours
CalendarSchedule that schedules purges at specific points on the calendar. For example, the following
schedule
setting specifies to run a purge on the last Sunday of each month at 1:01am:schedule=calendar * . 1 last 1 1
You set the purge cut-off date by supplying an integer value to the maxAgeDays
property—by default, set to 365. Thus, a value of 15 specifies that each scheduled purge removes versions that are 15 days old or older.
The exact purge cut-off timestamp is determined by the property roundPurgeCutoffToPreviousMidnight
. If set to true (default), the value supplied to maxAgeDays
is rounded to the previous midnight. If set to false, the purge cut-off timestamp is not rounded.
For detailed information on setting schedules, see the Scheduler Services section in the ATG Platform Programming Guide.
