New Features › Enhanced Submission Selection

Enhanced Submission Selection

A new initialization option is available for submission selection (choosing which job gets submitted next).

The enhanced submission selection feature can reduce the overall CPU usage while letting CA WA CA 7 Edition process more efficiently.

The feature builds on the use of CA Datacom/AD as the database. The SUBSEL=ENH keyword on the OPTIONS initialization statement controls it.

For the sites using workload balancing (WLB), be aware that enhanced submission selection uses a subset of WLB processing. Only the following WLB features are used:

• Class barriers (CLBARR BARA-9=)
• Total initiators (INITR TOTAV=)
• Tape drive counts (TAPE1/2 TOTAV=)
• Job priority as defined on the job. The value is treated as a constant (none of the awards or penalties are applied).

The subset of WLB used by enhanced submission selection is sufficient for most sites using WLB. Sites who feel they are receiving value from the other aspects of WLB can continue to do so. They can specify SUBSEL=NORM (the default) on the OPTIONS initialization statement.

You can use the /DISPLAY,PERF=SUBSEL to display the enhanced submission selection performance data.

Note: For more information about the enhanced submission selection, see the Systems Programming Guide.
