information record. The record that provides
descriptive information of schedules and jobs. There
is a schedule information record (SIR) and job
information record (JIR).
installation option. A value specified on the
CAIJGEN installation macro when Unicenter
CA-Scheduler is installed. This value controls
scheduling operations throughout the data center
unless it is overridden by values in Unicenter
CA-Scheduler's database.
JBR. Job base record. This record is required to
define a job.
JCR. Job criteria record. This record determines
when a job is to be selected for processing and lists
the predecessors for the job.
Julian date. A five-digit number of the form
yyddd, where yy is the year and ddd is the relative
day of the year (from 001 to 366). For example,
87305 is November 1, 1987.
keyword-defined explicit predecessors. Predecessors
that are ignored in the selection process and always
include at least one of the following keywords:
DSN GDG GBLxnn DOS PRED
The keywords START or SCD can also be used with
DOS or PRED.
levels of predecessors. In terms of a family tree,
the number of preceding "generations" (schedules or
jobs) with defined predecessors. The number ending
each job name following identifies each job's level of
predecessors.
JIR. Job information record. This record provides
descriptive information for a job.
JMR. Job message record. This record determines
who receives messages when a job begins, ends,
starts late, abends, is purged, or is interrupted.

job. Usually refers to work submitted to the CPU
for processing. However, Unicenter CA-Scheduler
expands the scope of that definition to encompass
all data processing tasks under Unicenter
CA-Scheduler's control. This can include pre-CPU
tasks such as data entry, jobs that run on the CPU,
and post-CPU tasks such as report distribution.
job number. One of four fields used to uniquely
identify each job definition. When a job needs to
run more than once during a production day, create
a job definition for each iteration by giving them
different job numbers.
job path. All the stations where a job is processed
as it moves through the data center.
JRC. Job reason code record. This record is used
assign time specifications which vary according to
the reason a job is selected for processing.
JRR. Job resource record. This record allows you to
define the resources necessary to run a job.
JOBA0 and JOBB0 have no predecessors.
(Their levels of predecessors = 0)
JOBA0 is JOBA1's predecessor.
(JOBA1's level of predecessors = 1)
JOBA1 is JOBA2's predecessor.
(JOBA2's level of predecessors = 2)
JOBA2 and JOBB0 are JOBA3's predecessors.
(JOBA3's level of predecessors = 3)
JOBA3 is JOBB4's predecessor.
(JOBB4's level of predecessors = 4)
The key word here is level. JOBA3 has four
different predecessors, but only three levels of
predecessors. Levels of predecessors is one factor
