Controlling SRM

You can control the system resources manager (SRM) through the workload manager. In releases earlier than z/OS® V1R3, an installation controlled SRM either through the IEAIPSxx and IEAICSxx parmlib members or through the workload manager. Controlling SRM through parmlib members was called workload management compatibility mode. Controlling SRM through the workload manager is called goal mode. Some parameters in the IEAOPTxx parmlib member applied only to compatibility mode (and are no longer valid), and some apply to goal mode.

With workload manager, you specify performance goals for work, and SRM adapts the system resources to meet the goals. SRM uses the same controls that exist today, but it sets them all dynamically based on the goals. For information on how to use workload manager, see z/OS MVS Planning: Workload Management.

While most information about how to use workload manager is in z/OS MVS Planning: Workload Management, many of the concepts that SRM uses dynamically in goal mode are explained in this publication, including the IEAOPTxx parameters.
