Workloads and service classes

To workload management, work is a demand for service, such as a batch job, an APPC, CICS®, or IMS™ transaction, a TSO/E logon, or a TSO/E command. All work running in the installation is divided into workloads. Your installation may already have a concept of workload. A workload is a group of work that is meaningful for an installation to manage and monitor. For example, all the work created by a development group could be a workload, or all the work started by an application, or in a subsystem.

You can create a service class for any combination of the above. You assign performance goals to the service classes, such as a response time goal, and you indicate how important it is to your business that the performance goal be achieved.
