The WebSphere Commerce MQ listener (formally MQSeries), or simply the MQ listener, is a component of WebSphere Commerce that enables integration with back-end systems by processing inbound messages via MQ. The MQ listener is a combination of the JMS-MQ CCF Connector to retrieve MQ messages, and the Program Adapter which is called to execute those messages.
The MQ listener has a set of predefined messages that help integrate WebSphere Commerce business processing with back-end or external system processing. Each incoming message activates processes within WebSphere Commerce to update database tables or perform other operations. Refer to the back-end integration and fulfillment integration message information for more details on the messages provided. In addition to the existing pre-defined messages, the listener supports message extensions and new messages.
For more information on enabling the MQ listener, refer to the WebSphere Commerce Additional Software Guide.
