- Bi-directional
- Messages flow in both directions between the bus and WebSphere MQ.
- To WebSphere MQ
- Messages flow only from the bus to WebSphere MQ.
That is, from WAS to a message broker in the WebSphere MQ network.
- From WebSphere MQ
- Messages flow only to the bus from WebSphere MQ.
That is, from a message broker in the WebSphere MQ network to WAS.
Broker stream queue
The name of the stream queue at the message broker in a WebSphere MQ network.
The broker stream queue in this instance is a queue on the WebSphere MQ queue manager to which the message broker is connected. This queue is being used as the input node for a message flow containing a publication node. Messages sent to this queue are processed by the message broker, then published to applications that have subscribed on the topic specified in the message.
Stream names are case sensitive.
After you type a new name, then save the changes, the name becomes available for selection in the drop-down list.
