Designing the WebSphere MQ infrastructure
You must create and manage the WebSphere® MQ resources that are required to support your brokers, and the applications that connect to them to supply or receive messages.
Brokers
A broker uses WebSphere MQ messages to provide information, status, and instructions about its internal operations. Connections are also required by each WebSphere Message Broker Toolkit with each broker with which it communicates.
Some of these resources that are required are created for you when you create brokers and execution groups. 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 Information Center online.
