Unicenter CA-Scheduler Job Management for VSE User Guide

6.1 Commonly Asked Questions
Once the tapes have arrived, an operator sets the value of the global parameter
GBLC4 to HERE-NOW. At that point, if any schedule or job is waiting for no
other reason but this variable, then the schedule will be started or the job will
be submitted.
It is very important to notice that global parameters are not reset
automatically. Someone must cause it to happen. Their values are saved on the
tracking file and always remain until they are reset to some other value or the
tracking file is reinitialized. Autoscan does not reset the global parameters.
A review of all the ways you can set, reset, and define global parameters
follows.
When you initialize the tracking file, all global parameters are set to zero (for
A-type), NO (for B-type), or null (for C-type).
If you want to see the current values of the global parameters, go into the
Online Monitoring panel and enter 6,D. The general Unicenter CA-Scheduler
Command Processor panel will be displayed with all of the global parameter
values. Another way to see the current values is to issue an operator command
GBL to display all defined global parameters, or GBLA for the numeric ones,
or GBLB or the YES/NO ones, or GBLC for the character ones.
To assign a value to a global parameter, you also go to the Online Monitoring
panel. Once there, enter 6,GBLxnn=value. You never really reset a value; you
type a new value each time. Another way to set global parameters is to use
the operator command SET GBLxnn=value. For example, SET GBLC1=SHIFT1
to mark the start of a specific shift. Another example, SET GBLC16=TP1HERE
to mark the arrival of a tape.
When you define the criteria for a schedule or job, you can specify which
global parameters and what values they are to contain for use as predecessor
conditions that have to be met before the schedule can be started or the job can
be submitted.
There is one rule you have to be sure to follow: a NOT reserved word
preceding a GBLxnn predecessor is NOT recognized. Therefore, NOT
GBLC01=CICS-UP will have the same affect as GBLC01=CICS-UP.
6.1.2.6 How Can I Run a Job Like an Edit Check Repeatedly until Its Output Is
Correct?
This is a situation where you want to keep running a job over and over again
until you get an indication that the rest of the application can run. You may
not know how many times it will take each day, since it depends on
everything being valid. There are two ways to achieve this type of processing:
■

Using the INTERRUPT field on the job base record
Using Auto-Reply processing.
