preRegisterListener() Preregister an anticipated subscription service. Some sending applications can anticipate requests for certified delivery even before the listening applications start running. In such situations, the publication service can preregister subscription services, so TIBCO Rendezvous software begins storing outbound messages in the publication service ledger. If the listening correspondent requires old messages, it receives the backlogged messages when it requests certified deliver. Input Parameters Type Description Session Name string Name of the session that anticipates the listener. Publisher Name string Name of the component for which the listener should be preregistered. Listener Session Name string Name of the subscription service to preregister. Returns OK if the subscription service was preregistered successfully, false otherwise.
