Differences between service integration and a WebSphere MQ network

This topic describes the main differences between messaging in a service integration bus on WebSphere® Application Server, and messaging in a WebSphere MQ network.

Service integration messaging uses messaging engines, whereas WebSphere MQ uses queue managers. For more information about queue managers, see WebSphere MQ queue managers.

Differences also exist between the reply queues, and reverse routing used in service integration and in WebSphere MQ. For more information, see Point-to-point messaging with a WebSphere MQ network.

Although service integration and WebSphere MQ both use messages as the mechanism for data exchange, the message formats are different. For more information about the differences in format, and to see how the WebSphere MQ link handles the formats, see WebSphere MQ messages.

WebSphere MQ applications consume messages from queues that are locally defined on a queue manager. In service integration the equivalent component to a WebSphere MQ locally defined queue is a queue point on the local messaging engine. In service integration there is no similar restriction imposed on the queue point and the location in the bus where the consuming application is connected.
