Figure 3-5. Case Study - Batch Initiator Simulation Inquiry Panel.
The characteristics of the simulation are as follows:
o The sample system has an initiator structure made up of
48 initiators, each of which serves a single job class.
o The data for the simulation comes from the CA MICS
database unit with an ID of B. The data comes from
the 01 cycle of the BATJOB and BAT_JS files.
o Aging will be performed for jobs with priorities 5 to 11,
and jobs are eligible for aging after one hour in the
queue at a given priority.
o Only data for the system TEST and the hours 7:00 through
17:59:59.99 is selected because the initiator structure
being simulated is in use only during the prime shift.
The initiators are routinely drained on this system at
7:00, so the input data is selected starting at 7:00.
This ensures that the simulation starts with all
initiators unoccupied, which improves the accuracy of the
simulation.
o The simulation is limited to data from January 7, 1988,
between the hours of 7:00 and 17:00 for classes A, B, C,
D, F, and W.
o The finest level of data kept for reporting is at
30-minute intervals.
o The files from which the input data is selected will be
written to the file PERDDOUT.BAT05.
Because we entered Y (Yes) in the Specify extended options
field on the Batch Initiator Simulation inquiry panel, the
Extended Options Menu was displayed. (Section 3.1.6 provides
a complete description of all available extended options.)
This enabled us to enter Y (Yes) in the Save selected input
observations field, which brought us to the Save selected
input observations panel. Figure 3-6 shows the entries we
made in the Save selected input observations panel to save
our input data.
