Differences between service integration and a WebSphere MQ network

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

In place of the messaging engines that operate within the service integration bus in the WebSphere Application Server, WebSphere MQ has the concept of queue managers. You can read about the important characteristics of queue managers in WebSphere MQ queue managers.

Reply queues, and reverse routing paths differ between WebSphere Application Server service integration and WebSphere MQ. You can read more about the differences in Point-to-point messaging with a WebSphere MQ network.

While WebSphere MQ and WebSphere Application Server service integration share the concept of messages, the formats are different. You can read more about the important differences, and how the WebSphere MQ link treats them in WebSphere MQ messages.

In WebSphere MQ an application can only consume messages from queues that are locally defined on a queue manager. In service integration the closest concept to WebSphere MQ's "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.
