Putting Multi-Trans TPs in their Own Class

In general, it is a good idea to group TPs with similar characteristics in the same class. Therefore, place TPs with the same response time goals, with the same SYSOUT requirements, and with the same schedule type in the same class.

For multi-trans TPs, however, IBM® recommends that each TP scheduled as multi-trans be assigned to a unique class of transaction initiators. If multi-trans TPs are mixed in a class with other multi-trans TPs or with TPs scheduled as standard, the minimum set of transaction initiators available for that class of TPs might change frequently depending on the type of transaction that needs to be processed. If a multi-trans TP takes a long time to initialize, other TPs in the class might be forced to wait for initiators.
