Configuring the Scheduler
To configure the scheduler:-
Click Configure to open the Edit Schedule dialog box.

-
Select the interval type and frequency. The name of the frequency drop-down list changes based on your selected interval type (for example, if the interval is Minute, the frequency list is named Every; if the interval is Daily, the frequency list is named Time of Day; and so on).
The following list provides the values that you can select for each interval type:
- Minute: Choose intervals of 1, 5, 10, 15, 20, or 30 minutes in the Minutes field. The Minute interval starts on the hour. For example, if you choose Every 10 Minutes, your job will be scheduled to execute at :00, :10, :20, :30, and so on.
- Hourly: Choose specific minutes past an hour in the Minute Past the Hour field.
- Daily: Choose a specific time of day in the Time field.
- Weekly: Choose a specific day of the week and a time from the Day and Time fields.
- Monthly: Choose a specific day of the month and time from the Day and Time fields.
- Custom: Enter a Cron statement in the Cron Expression field.
When the job that is currently running takes longer than the scheduled interval, skips the next run. For example, if you set a job to run every 10 minutes but one run takes 15 minutes to complete, the next run is skipped. The following table illustrates this particular example, but the skip concept applies to all of the interval types. - Click Save to save your configuration.
