Moving from WebSphere Event Broker on a distributed platform to z/OS

Taking these into account, recreate your broker and User Name Server resources on z/OS and deploy your message flows and execution groups to a WebSphere Event Broker for z/OS broker. If you have extended WebSphere Event Broker in a distributed environment with user-defined parsers or message processing nodes, port them to run under z/OS.

Also consider the following points:
  • Floating point conversion: z/OS runs under z/OS floating point format, so floating point operations on z/OS run in a different range and accuracy from distributed platforms.
  • Administration commands are partially implemented as console commands and partially as JCL commands.
  • Event log messages: All address spaces have a JOBLOG where messages appear. In addition to this, all messages appear on the SYSLOG, with important operator messages being filtered to the console through MPF (Message Processing Facility).

Moving user applications

You can write your own applications to work with WebSphere Event Broker. If these applications use the common subset of functionality of all WebSphere Event Broker brokers, no migration is necessary. If you are using functionality that is available on some WebSphere Event Broker platforms only, for example message segmentation and WebSphere MQ message groups, be aware that WebSphere Event Broker for z/OS does not provide support for this migration.
