TOP Scope Facility

Within the scope of work defined through inclusions and exclusions of job names and programs, the scope is further drastically reduced by the TOP Scope. The TOP Scope facility identifies the job steps consuming the greatest resources and limits CA Mainframe Application Tuner measurements to this group.

The TOP Scope parameter is maintained by the administrator. It may be a value from 0 - 999. A value of 0 indicates that the statistical alert approach is disabled. In all other cases, the TOP Scope defines how many important job steps should be statistically observed.

See the Administration Guide for details about the processing logic that determines whether a job step is among the top resource consumers. Statistical alerts and CA Mainframe Application Tuner measurements are limited to the members of this group of top consumers.

The TOP Scope can be used to control

• Initiation and number of generated OPEN statistical alerts.
• Generated alerts for all modified and new modules.

  See the Administration Guide for details about defining these parameters.

• How user alerts, initiated through the online dialog, are handled.

  User defined alerts that request measurements may use the TOP Scope. If used, only job steps of user alerts that are in the TOP Scope have OPEN alerts and their measurements are stored.

The following graphic illustrates how the batch scope reduction works.
