By default, scheduling information (such as schedule state, and the details of the schedule run) is stored in RAM. This means that such information is lost when the server is rebooted. The schedule configuration is not lost when the server is shut down, and normal scheduling continues when the server is restarted. However, there are no details of missed schedule runs that should have occurred during the period the server was unavailable.
You can configure schedules to be persistent, which means that the scheduling information is stored in the internal repository, rather than in RAM. With persistent schedules, scheduling information is retained when the server is shut down. Any previously scheduled jobs can be rescheduled automatically when the server is restarted.
To configure persistent schedules, set
true in the schedule configuration.
If the server is down when a scheduled task was set to occur, one or more runs of that schedule might be missed. To specify what action should be taken if schedules are missed, set the
misfirePolicy in the schedule configuration file. The
misfirePolicy determines what IDM should do if scheduled tasks are missed. Possible values are as follows:
The first run of a missed schedule is immediately implemented when the server is back online. Subsequent runs are discarded. After this, the normal schedule is resumed.
All missed schedules are discarded and the normal schedule is resumed when the server is back online.
