Preregistering a Certified Subscriber

You can add one or more certified subscribers or listeners for the publisher adapter that sends messages on subjects using the TIBCO Rendezvous Certified (RVCM) quality of service. The name of the subscriber is added to the preregistered list of the publisher adapter. The subscriber can be a TIBCO ActiveMatrix Adapter for Database subscriber, or any other TIBCO Rendezvous subscriber.

A subscriber adapter on the preregistered list is certified to receive all messages sent on the specified subject by using the RVCM quality of service. If a subscriber is not preregistered, it might miss one or more of the initial messages sent by the publisher adapter.
Note: When you preregister a subscriber, note the following conditions:
  • Wildcard TIBCO Rendezvous subject names are not supported for preregistered listeners.
  • Preregistration does not work when parametrized subjects are used.
  • When you use Publication Service or a business process to send messages to Subscription Service, it is best practice to configure the preregistered listeners for the RVCM quality of service to prevent data loss.

You can preregister a certified subscriber in TIBCO Business Studio. For specific steps, see Preregistering in TIBCO Business Studio.

Apart from preregistering a certified subscriber in TIBCO Business Studio, you can add a Subscriber adapter to a preregistered list by setting the preregistered listeners in the adbagent.tra file. For specific steps, see Setting Preregistered Listeners in TRA Properties File.
