Unicenter CA-Scheduler Job Management for VSE User Guide

6.1 Commonly Asked Questions
Operator Console
Any operator command can be issued from the operator
console by directing it to Scheduler. Prefix the command with
SC followed by a blank space.
Batch Program (CAJUCMD0)
Operator commands can be issued from a batch program
called CAJUCMD0 which means that you could embed a step
calling this program in your production JCL that could take
certain actions dependent on, for example, condition code
settings. Since you have the ability to cause any Scheduler
operator command to be issued, you could send messages to
specific users or the operator console, you could start another
job, or you could set global variables.
You can even issue these commands based on conditions
coded in an IF statement. You can test against the status of
other jobs, any schedule, user-defined globals, and many
others. The subtopic Issuing Online Operator Commands In
Batch Mode in the chapter "Techniques" describes this in
detail.
6.1.4.2 What Is the Difference Between FORCE, SUBMIT, RERUN, RUN, ADD,
REQUEST, and SREQ?
Each of these commands causes a job or schedule to be activated in some form.
The following describes how each command works.
FORCE
Causes a schedule on the tracking file to be started regardless
of why it is currently waiting. It also can cause a job to be
submitted regardless of why it is currently waiting.
SUBMIT and RERUN
Cause a job to be resubmitted. It will not wait for an early
time or for predecessors: it is submitted immediately. If the
schedule that owns the job is not in START status, it will be
set to START status. Use RERUN or SUBMIT instead of
FORCE when a job has abended, failed, ended, canceled, or
been interrupted. FORCE is used to make a job start the first
time. RERUN substitutes Unicenter CA-Driver restart
parameters if LIBTYPE=DRIVER is defined and the JCL is not
staged or restaged. The only difference between SUBMIT and
RERUN is the Unicenter CA-Driver parameters they use:
SUBMIT uses the normal parameters while RERUN triggers
the restart parameters.
RUN
Causes a schedule or job that exists on the database to be
added to the tracking file. These schedules and jobs are ones
that were not selected in today's workload or they may have
been canceled or completed. This is different than FORCE and
RERUN in that a fresh copy is obtained and all times,
predecessors, and resources are properly evaluated.
