Brokers
A broker uses WebSphere MQ messages to provide information, status, and instructions about its internal operations. Connections are also required by each IBM® Integration Toolkit with each broker with which it communicates.
Some of these resources that are required are created for you when you create brokers and integration servers. The requirements associated with the broker are described in WebSphere MQ resources for brokers.
Applications and message flows
Your applications exchange messages and other data by communicating with message flows that are running in the broker. You can connect your applications to the broker by using one of the supported communications methods. If your applications are written to use WebSphere MQ, the requirement for the channels or client connections are determined by the types of nodes that you include in your message flows. These resources are application-specific, and you must create these resources yourself.
The following nodes might require WebSphere MQ resources:
- MQInput and MQOutput
- MQReply and MQGet
For more information about creating resources, see the Intercommunication section
of the 
WebSphere MQ Version 7 product documentation online.
