Why MVS workload management?

Before the introduction of MVS™ workload management, MVS required you to translate your data processing goals from high-level objectives about what work needs to be done into the extremely technical terms that the system can understand. This translation requires high skill-level staff, and can be protracted, error-prone, and eventually in conflict with the original business goals. Multi-system, sysplex, parallel processing, and data sharing environments add to the complexity.

MVS workload management provides a solution for managing workload distribution, workload balancing, and distributing resources to competing workloads. MVS workload management is the combined cooperation of various subsystems (CICS®, IMS/ESA®, JES, APPC, TSO/E, z/OS® UNIX System Services, DDF, DB2®, SOM, LSFM, and Internet Connection Server) with the MVS workload management (WLM) component.

This information identifies the problems that led to workload management, and describes the high-level objectives for the long term.
