Specifying delivery rules parameters for JMS activities

Specifying the Delivery Rules parameters is one of the tasks you must complete to configure a JMS activity.

About this task

For more information about the configuration tasks in the Checklist, see the help topic for the specific JMS activity.

Procedure

  1. In the Checklist, select Delivery Rules. The Delivery Rules panel opens.
  2. For the Poll Message activity only, specify the polling interval. By default, the activity polls for changes every second.
  3. Select Batch objects to process the job as a batch.
  4. Select one of the following delivery options.
    Note: The delivery options available depend on the JMS activity. Not all delivery options are available for every JMS activity.
    Delivery Option Description
    ATLEAST_ONCE A persistent mode, in which the JMS Provider insures that a message is not lost. As a result, there are chances that the client can receive multiple copies of a single message. 
    ALMOST_ONCE In this non-persistent mode, a message may be lost, but JMS does not deliver multiple copies of a message.  
    EXACTLY_ONCE In this persistent mode, JMS delivers a message once and only once.
