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.
Before you begin
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.
About this task
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.
Procedure
- In the navigation pane, click one of the following paths:
- In the content pane, either click New to
add a new broker profile, or click the name of a existing broker profile
that you want to modify.
- Add or modify the properties of the broker profile.
For information about the broker profile properties (name,
description, broker queue manager name), see Publish/subscribe broker profiles [Settings].
For an existing
broker profile you can only modify the description. Note that, for
an existing broker profile created by using the foreign bus connection
wizard, the broker profile name was generated automatically by adding "_broker_profile" to
the end of the broker queue manager name.
- Optional: Under Additional properties, configure
the topic mappings for this broker profile. For more information,
see Adding or modifying topic mappings on the WebSphere MQ link publish/subscribe broker.
- Click OK.
- Save your changes to the master configuration.
What to do next
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. You can do this either
by modifying the message broker configuration on the
WebSphere MQ network, or by modifying
the service integration bus configuration. See
