Possible extensions

The sample application illustrates many aspects of a WebSphere MQ Publish/Subscribe system. Possible extensions that might be implemented by the user include:

• Distribute the results service and match simulators across multiple connected brokers.

• Extend the application to handle more than one sport, and have a results service running for each sport.

• Extend the results service to publish the final score when a match ends, and add another application that subscribes to these publications to produce a table of results.

• Extend the match simulator to confirm that a results service is subscribing toSport/Soccer/Events/* topics before it starts publishing. This can be done using metatopics.

• Change the format of the user data in the publications, create a user defined format, and write a data conversion exit to enable the passing of publications between different platforms or languages.
