Default topic routing

In WebSphere Business Integration Message Broker, the Topic property of the MQInput node can be used to route messages that do not contain publish/subscribe parameters. This feature does not apply to MQRFH subscribers.

MQRFH subscribers expect to receive publications, with a well-formed MQRFH header, from both WebSphere MQ Publish/Subscribe and WebSphere Business Integration Message Broker clients.

In the latter case, the original MQRFH2 header is converted as described earlier in this topic. However, if the message does not contain publish/subscribe information in either an MQRFH or an MQRFH2 header, the default topic is not used to send publications to an MQRFH subscriber.
