2.4.7 Tape Drive Simulation Analysis Inquiry

The unavailability of sufficient tape drives can adversely
affect performance, especially during periods of heavy batch
job activity.  If sufficient tape drives are not available,
batch work is delayed, and operators may have to vary tape
drives from one system to another.

The Tape Drive Simulation Analysis inquiry allows you to
analyze time periods that have significant tape drive
unavailability problems.  You can also model the effects of
moving existing work to different time periods, adding
additional tape usage, and tape drive improvements.  Thus,
you can investigate both the effects on performance of
rescheduling existing jobs and the capacity implications of
added tape drive usage.
