Workload management work environments

Cooperation between MVS™ and the subsystem work managers enable the sysplex-wide specification and reporting of goals defined for work in the service policy. You can define goals for the following kinds of work:

IMS™, if you have IMS/ESA Release 5 or higher
CICS®, if you have CICS/ESA 4.1 or higher
z/OS® UNIX System Services
JES2
JES3
APPC
TSO/E
SOMobjects®
WebSphere® Application Server objects (CB)
LSFM
DDF, if you have DB2® V4.1, or higher
DB2, if you have DB2 V 5, or higher
IWEB, if you have Internet Connection Server V 2.2, or higher, Domino® Go Webserver, or IBM® http Server Powered by Domino (IHS powered by Domino)
MQSeries® Workflow
SYSH, if you need to manage non z/OS partitions
NETV

Arriving work is associated with a service class, and therefore a goal and possibly a resource group. You get feedback from RMF™ as to how well the system is doing in meeting the goals. RMF provides sysplex-wide workload management reporting, providing sysplex-wide as well as single system feedback on the goals through the Post Processor and Monitor III realtime reports. The reports show kinds of delays seen by subsystem work managers such as CICS and IMS. SDSF displays workload management related information.

Workload management understands which address spaces (INITs, AORs, MPPs, BMPs, TORs, FORs) are involved in processing work within a service class, and matches the resources to meet the goal. Information as to how well each system is doing in processing towards a service class goal is recorded in SMF records on each system.
