Using TIB/Rendezvous with the SAS Common Messaging Interface

Starting with Release 8.2 of SAS Integration Technologies, the SAS Common Messaging Interface included support for TIB/Rendezvous Release 6.3. Integration Technologies 9.1 supports both the reliable and certified message delivery features of TIB/Rendezvous Release 7.1.

TIB/Rendezvous is a leading messaging middleware product from TIBCO Software, Inc. Like IBM's WebSphere MQ (previously named MQSeries) and Microsoft's MSMQ, TIB/Rendezvous makes it easy to create distributed applications across heterogeneous systems.

The SAS Common Messaging Interface includes messaging functions that are common to WebSphere MQ, MSMQ, and Rendezvous. However, the TIB/Rendezvous message delivery system differs from the other transports in some important ways. Developers must take these differences into account when using the Common Messaging Interface to support Rendezvous-based applications. The main differences are as follows:

• Rendezvous uses an approach called subject-based addressing. While both WebSphere MQ and MSMQ deliver messages to specific destination queues using queue names, Rendezvous broadcasts messages that have been labeled with user-defined subject names. Data consumer applications listen for particular subject names and receive messages only when the subject name matches a name being listened for. The communicating programs must agree in advance on the subject names to be used and the forms of messages to be exchanged.

• Because messages are broadcast to subject names instead of specific destination queues, a message can be received only by stations that are online and actively listening for the subject name associated with the message.
