Automating Tasks Using Schedules and Events
Understanding schedules
Schedule definitions have several components to them, to permit flexibility:
Name Each schedule definition has a name. You can assign more than one schedule to a particular event, which can be useful in designing complex schedules.
Start time You can define a start time for the event, which is the time that it is first executed.
Range As an alternative to a start time, you can specify a range of times for which the event is active. The event occurs between the start and end time specified. Frequency is determined by the specified recurrence.
Recurrence Each schedule can have a recurrence. The event is triggered on a frequency that can be given in hours, minutes, or seconds on a set of days that can be specified as days of the week or days of the month. Recurring events include an EVERY or ON clause.
