WebSphere® MQ allows multiple messages to be treated as a group, or as segments of one larger message. WebSphere Message Broker provides support for WebSphere MQ message grouping and partial support for message segmenting.
You can use the MQInput and MQOutput nodes to receive and send messages that are part of a WebSphere MQ message group. You can use the MQOutput node to send messages that are segments of a larger message.
