You can configure a local connection to WebSphere® MQ by specifying the Connection properties on the MQInput, MQOutput, MQGet, or MQReply node.
WebSphere MQ is available as a separate installation package, and your IBM Integration Bus license entitles you to install and use WebSphere MQ with IBM Integration Bus. For more information, see Enhanced flexibility in interactions with WebSphere MQ and Installing WebSphere MQ.
If your WebSphere MQ queue manager is running on the same machine as your integration node, you can specify a local connection to enable your IBM Integration Bus message flows to access messages on WebSphere MQ queues.
If an MQ node does not have connection properties set on the node or in an MQEndpoint policy, it will use the connection details of the queue manager that is associated with the integration node at run time. If no connection details are set on the node or in a policy, and if no queue manager is specified for the integration node, the message flow cannot deploy.
If you later decide that you want to control connection properties by using an MQEndpoint policy, property values that are set on the MQ Connection tab are ignored when a policy is attached to the message flow node. If you want to revert to using the connection details of the queue manager that was specified on the integration node, remove the settings for the Policy URL and MQ Connection tab properties.
