On Notification Timeout

Process Starter

The On Notification Timeout process starter specifies a process to execute when a timeout is reached for storing notification data for a Notify activity. See Notify for more information about the Notify activity and how to specify a timeout for storing notification information.

You can specify an On Notify Timeout process definition for a specific Notify Configuration. The process definition with the On Notification Timeout process starter executes when a Notify activity with a matching Notify Configuration experiences a timeout. You can specify one or more On Notify Timeout process definitions for specific Notify Configurations, but you should not create more than one process definition for the same Notify Configuration. Once a Notify activity experiences a timeout of its stored notification information, that timeout can only apply to one On Notification Timeout process definition.

You can also specify that an On Notification Timeout process definition applies to any Notify activity that experiences a timeout. If there is no On Notification Timeout specified for the Notify Configuration of the Notify activity, the process engine calls the On Notification Timeout process definition that has the Any Notify Config field checked.

Notify timeouts cause the notify information to be marked for removal, but the information is removed at regular intervals. The default interval for checking Notify timeouts is 60 seconds, and therefore, the OnNotificationTimeout process starter only starts processes after each interval. If you want to reduce the interval, you can do so by altering the Engine.WaitNotify.SweepInterval custom engine property to the desired number of seconds. However, as you decrease the number of seconds in the interval you will incur further engine overhead.

Configuration

The Configuration tab has the following fields.

Field	Description
Name	The name to appear as the label for the resource.
Description	Short description of the process starter.
Any Notify Config	Specifies that this process starter should execute when any Notify activity experiences a timeout, and there is no On Notify Timeout process definition specified for the Notify Configuration for the activity. When this field is checked, the Notify Configuration field becomes disabled. Uncheck this field when you want to specify a process definition for a specific Notify Configuration.
Notify Configuration	Only appears when the Any Notify Config field is unchecked. This field allows you to specify the Notify Configuration that this process applies to. Only timeouts for Notify activities with a matching Notify Configuration will start a process instance. Only one On Notification Timeout process definition can correspond to any Notify Configuration. That is, you cannot create multiple process definitions and use the same Notify Configuration.

Output

The output for the activity is the following.

Output Item	Datatype	Description
notificationData	Object	This element contains the schema specified in the Notify Configuration of the Notify activity that has timed out.
