Maintenance of Tab Page Background Job 

Use

The event queue is read at regular intervals by a background job. The events found are delivered to the registered event receivers.

Integration

This tab page is maintained within administration of the event queue.

Features

You can make the following settings:

The operation mode can be used to control how often the background job is to be started.

The background job is scheduled periodically with the specified interval.

The intervals at which the background job is to be started can be defined as dependent on the content of the event queue. You should, for example, schedule the background job for a shorter interval if there are still events in the event queue after a processing run. You should choose a longer interval if the event queue does not contain any more events.

Adapting the interval dynamically can relieve the load on the system, since the background job is started less frequently.

However, the processing of the events may also be delayed because of the longer interval.

To switch operation mode, you must first remove the current background job from the schedule.

Here you specify the number of events to be read each time the event queue is read.

Here you specify the time interval between two read accesses. The specification has the following effect:

Processing is carried out with the predefined interval. The interval can only be changed if the background job is removed from the schedule. It is considered when the job is rescheduled.

The time interval is adhered to if the event queue contains more events after a processing run. The interval can even be changed when the background job is scheduled, since the job reschedules itself after every processing run (depending on the content of the queue).

This interval is adhered to if there are no more events after the queue has been read. This setting can only be made with processing that depends on load.
