Simulation and Forecasting Facility And Automatic Tape Adjustment in CONTROL-M

Simulating Job Execution and Forecasting Resource Usage: Simulation and Forecasting
Facility

Using statistics accumulated by the Statistics facility, the Simulation and
Forecasting facility simulates the actions of the CONTROL-M monitor under
the conditions specified in simulation parameters.

The Simulation and Forecasting facility enables you to forecast anticipated
job load for a specified time in the future, and to forecast the effects of
possible changes to the system, such as the impact of:
• removing four tape drives
• increasing CPU power by 30%
• changing the time at which certain jobs are executed

The Simulation and Forecasting facility can improve the efficiency of your
site. It can help with resource and configuration decisions, and it can help
with the planning of workload scheduling to achieve maximum utilization of
resources


Automatic Tape Adjustment

The Automatic Tape Adjustment facility collects and analyzes statistics
regarding tape drive usage, and automatically allocates the appropriate
number of tape drives at job order time. This facility, which can be
implemented by your INCONTROL administrator, overrides any tape drive
Quantitative resource value specified in the job scheduling definition. For
more information, see the descriptions of the Statistics screen in Chapter 2,
“Online Facilities,” and the RESOURCE parameter in Chapter 3, “Job
Production Parameters.”
