Terms used in MVS workload management

The following terms are used in the description of MVS™ workload management:

classification rules
The rules workload management and subsystems use to assign a service class and, optionally, a reporting class to a work request (transaction). A classification rule consists of one or more work qualifiers. See Defining classification rules.
compatibility mode
A workload management mode for an MVS image in a sysplex using the pre-workload management MVS performance tuning definitions from the IEAICSxx and IEAIPSxx members of the SYS1.PARMLIB library.
goal mode
A workload management mode for an MVS image in a sysplex using an MVS workload management service definition to automatically and dynamically balance its system resources according to the active service policy for the sysplex.
report class
Work for which reporting information is collected separately. For example, you can have a report class for information combining two different service classes, or a report class for information on a single transaction.
service class
A subset of a workload having the same service goals or performance objectives, resource requirements, or availability requirements. For workload management, you assign a service goal to a service class. See Defining service classes.
service definition
An explicit definition of all the workloads and processing capacity in a sysplex. A service definition includes service policies, workloads, service classes, resource groups, and classification rules. See Setting up service definitions for MVS Workload Manager.
service policy
A set of performance goals for all MVS images using MVS workload manager in a sysplex. There can be only one active service policy for a sysplex, and all subsystems in goal mode within that sysplex process towards that policy. However, you can create several service policies, and switch between them to cater for the different needs of different processing periods.
workload
Work to be tracked, managed and reported as a unit. Also, a group of service classes.
workload management mode
The mode in which workload management manages system resources in an MVS image within a sysplex. The mode can be either compatibility mode or goal mode.
