To summarize: Use as few service classes as you can to separate the work and as many report classes as you like / need for reporting. There is a limit of 999 report classes and there really should be no more than about 30 active service classes on an LPAR (YMMV). You can have more than 30 in your policy if some classes are only active on certain LPARs. But less is still better because there is only so much WLM can do at each evaluation / adjustment cycle. Here: I have a couple of service classes each for CICS, DB2, DDF, CB (WebSphere), STC, production batch and test batch and SAP (used prior to DB2 V8 and only on a couple of LPARs). Test batch really has one class + a discretionary class which 95% of all test batch falls into. I have a single class for TSO and OMVS (with periods). But there are report classes for *every* production CICS region, WAS region, and DB2 subsystem as well as many STCs (CATALOG, VTAM, TCPIP, session manager) to name a few). But most STCs are lumped into a couple of other groups with "monitors" being one of them.
