Configuring the MQ messaging interface

The messaging interface that is used by WebSphere® MQ user defined functions is a simple programming interface that provides support for point-to-point messaging and publish and subscribe messaging.

The messaging interface simplifies application development by moving function from the application program into a database structure. The three essential parts of the messaging interface syntax are the service, the policy, and the message. The service defines where to send the message. The policy defines how to send the message. The message is what is sent. The service encapsulates local or remote queues. The policy encapsulates options for the message such as priority or retry. The message part might contain application message data and attributes such as format or correlation identifiers.
