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 MQI for more information) and some security issues to consider (see Multicast security for more information).

• Multicast and the MQI
  Use this information to understand the major Message Queue Interface (MQI) concepts and how they relate to IBM MQ Multicast.
• High availability for multicast
  Use this information to understand IBM MQ Multicast continuous peer-to-peer operation; although IBM MQ connects to an IBM MQ queue manager, messages do not flow through that queue manager.
• Data conversion in the MQI for multicast messaging
  Use this information to understand how data conversion works for IBM MQ Multicast messaging.
• Multicast exception reporting
  Use this information to learn about IBM MQ Multicast event handlers and reporting IBM MQ Multicast exceptions.
