The task of implementing MVS™ workload management is part of the overall task of planning
for, and installing, MVS.
Implementing MVS workload management generally involves the following steps:
Establishing your workloads.
Setting your business priorities.
Understanding your performance objectives.
Defining critical work.
Defining performance objectives based on current business needs.
Get agreement for your workload performance objectives.
Specify a service level agreement or performance objectives.
Specify an MVS WLM service definition that uses the information from step 7.
Note:
It is helpful at this stage to record your
service definition in a form that helps you to enter it into the MVS workload manager ISPF
application. You are recommended to use the worksheets provided in the z/OS MVS Planning: Workload Management manual, SA22-7602.
Install MVS.
Set up a sysplex with a single MVS image, and run in workload manager compatibility
mode.
Upgrade your existing XCF couple data set.
Start the MVS workload manager ISPF application, and use it in the following steps.
Allocate and format a new couple data set for workload management. (You
can do this from the ISPF application.)
Define your service definition.
Install your service definition on the couple data set for workload management.
Activate a service policy.
Switch the MVS image into goal mode.
Start up a new MVS image in the sysplex. (That is, attach
the new MVS image to the couple data set for workload management, and link it
to the service policy.)
Switch the new MVS image into goal mode.
Repeat steps 18 and 19 for each new MVS image in the sysplex.
Notes:
Current release support for MVS workload manager is initialized automatically during CICS® startup.
All CICS regions (and other MVS subsystems) running on an MVS image with MVS workload management
are subject to the effects of workload manager.
