Porting the Publication Notification Message Flow to System z Broker IBM-CICS

No material changes are required to have the pub/sub message flow run on a System z broker. Of course, the CICSWSAP/AddressChange publication needs to be registered against the System z broker, which works exactly the same way as the Windows broker. Registering subscriptions is slightly different because we need to write to a remote queue. Staying with RFHUtil, we have two options.

  1. Use RFHUTILC - a WMQ Client version of RFHUTIL that is included in the IH03 supportpac. This facilitates connecting to the System z WMQ manager MQ8G as a WMQ client. We then write our subscription message to MQ6G’s local SYSTEM.BROKER.CONTROL.QUEUE exactly the way we did for the Windows broker.
  2. Use RFHUTIL, specifying a remote queue. This requires that our local queue manager AJGBRK1 has functioning channels to the System z queue manager MQ8G. It is then just a case of specifying the remote parameters, as shown in Figure.
