A publish/subscribe broker profile, and associated topic mappings, allows publication and subscription with a broker in a WebSphere® MQ network. You can use the administrative console to define a broker profile on a WebSphere MQ link, forming a publish/subscribe bridge with a WebSphere MQ network.
You have to know the name of the bus, messaging engine name, and the name of the WebSphere MQ link on which you intend to create or modify the broker profile. You also have to know the queue manager name for the message broker in the WebSphere MQ network where the input queues for the required publication message flows are located.
When you use the foreign bus connection wizard to connect a bus and a WebSphere MQ queue manager to use publish/subscribe messaging, you can define a publish/subscribe broker profile and associated topic mappings. Alternatively, you can use the foreign bus connection wizard to connect a bus and a WebSphere MQ queue manager to use point-to-point messaging, then later modify the WebSphere MQ link for publish/subscribe messaging by adding a publish/subscribe broker profile and associated topic mappings to the link.
After you have created the broker profile you must ensure that the service integration bus has sufficient authority on the message broker instance to send subscription requests.
