Multicast programming

Use this information to learn about the IBM® MQ Multicast programming tasks such as connecting to a queue manager and exception reporting.

IBM MQ Multicast was designed to be as transparent to the user as possible and yet still be compatible with existing applications. Defining a COMMINFO object and setting the TOPIC object's MCAST and COMMINFO parameters, means that existing IBM MQ applications do not require substantial rewriting to use multicast. However, there might be some limitations (see Multicast and the Message Queue Interface for more information) and some security issues to consider (see Multicast security for more information).
