Unicenter CA-Scheduler Job Management for VSE User Guide

1.1 Beginning with the Basics
Ironically, job scheduling for multi-million-dollar computers is often handled
with an in-box or a chalk board. With Unicenter CA-Scheduler, you can use
the computer you already have to automate production.
Unicenter CA-Scheduler looks at job processing the same way you do: jobs
start and end with the user and a job is not done until the output is delivered.
If you trace the path of a job through your data center, it passes through
different areas before and after CPU processing:
Unicenter CA-Scheduler calls each of these areas a workstation and has you
assign numbers to them. Since all sites have JCL setup and CPU processing,
Unicenter CA-Scheduler assigns those station numbers automatically (stations
39 and 40). Notice that pre-CPU station numbers are in ascending order up to
39. Post-CPU stations are also numbered sequentially and can range from
41-99. This manual will reference the station numbers shown in the diagram
preceding.
Unicenter CA-Scheduler has you number workstations in ascending order for a
reason: that sequence tells Unicenter CA-Scheduler the logical flow of work
through your data center. Not all jobs are processed at every workstation:
some only run on the CPU, but if a job is scheduled at stations 39 and 40,
Unicenter CA-Scheduler knows that JCL setup should finish at station 39
before the job can be submitted to the CPU (station 40). To prevent mistakes
and reruns, Unicenter CA-Scheduler enforces workstation sequences: all of a
job's pre-CPU work must complete before its CPU processing can begin.
Unicenter CA-Scheduler can also think about work the same way you do. If
your production jobs are called AR004 or ARDAILY, use those same names
