Output from computer processing, the work that
has been completed, may take the form of a printed
document, magnetic tape, or magnetic disk or diskette.
In all cases, you are responsible for and must ensure that
all completed jobs run successfully. In addition, you are
responsible for identifying and coordinating the various
outputs for each job, and for initiating their correct
To determine whether a job (or system) ran
successfully (to a normal EOJ) and that all processing
steps were properly performed, you may have to review
the computer console printout. This printout indicates
such things as the number of input records read, the
various input files updated, all error conditions (error
messages) that the operator encountered during the run,
and the resulting actions taken, the various output files
created, and so on.
Most of the time, the computer console printout will
provide you with the answers you are looking for when
it comes to reconciling processing discrepancies. For
example, it will inform you of the reasons certain output
products, tapes, diskettes, or report listings, were not
produced. Possibly the operator selected an incorrect
program option, or the input parameters were incorrect
or incomplete before starting the job. In short, you are
responsible and also accountable for every job you
work on, from the time it is submitted by the user until
its delivery back to the user.
When checking the users output, you should once
again refer to the run sheet and/or task folder to verify
that all items requested were, in fact, produced. If the
output is in the form of magnetic tape, disk, or diskette,
be sure it is labeled properly, given the proper
classification, and it is on the appropriate media
(magnetic media that has been designated for mail-out
or distribution only).
When checking reports, make sure that they were
run on the proper forms (size and type), that no pages are
missing and the correct number of copies were printed,
and that all print is legible and lined up properly.
Once it is completed, you then package each copy
of the report, along with any other output products and
the original input, place it in the proper pickup area, and
log the job out in the job control log. You may need to
notify the user when the job is ready.
If, during the course of checking over the users
output, you happen to come across something unusual
or you find an error, by all means pull (reject) the job
immediately, bring it to the attention of your superior,
and notify the user of the delay. Even at this late stage, it
is better to reject a job to correct any problems or
discrepancies rather than release it, only to have it
returned for rerun later.
You work in air-conditioned environments that
other AIS personnel (programmers, analysts, and so on)
would probably consider intolerable. The coolness of
the computer room or center is a constant source of
discomfort. Computer rooms have to be kept at a
constant and fairly cool temperature to ensure ideal
operating conditions and prevent equipment failures.
The humidity must also be controlled, for the protection
of the equipment and storage media.
accomplished by some sort of dehumidifier system.
Although the requirements usually call for 70°F to 74°F,
temperatures often range from 65°F to 70°F, and the
humidity ranges between 30 to 60 percent. Fortunately
for us, most minicomputers and microcomputers
generate far less heat and humidity than mainframes
during operation and, as a result, require only a minimal
amount of cool air.
You will be using a hypothermagraph to monitor the
temperature and humidity of the computer room. There
are several different models and styles of
hypothermagraphs, each with its own specific operating
Check the operators manual for the
specifics of your equipment. The hypothermagraph
uses a paper chart and marking pens to record the
temperature and humidity. The chart is normally a
7-day graph showing the day and a number range. It
uses two different colors, usually red for humidity and
blue for temperature, to show the temperature and
humidity on the chart.
COMPUTER CONSOLE OPERATION
CPUs arent the computers you may have seen in the
movies with all the blinking lights, although their basic
functional units are still the same. The CPU of today,
regardless of its size, still contains an arithmetic-logic
section, a control section, and an internal storage
(memory) section, as we discussed in chapter 1.
However, todays CPU contains relatively fewer lights,
switches, levers, and dials when compared to earlier
models. So you may be thinking, but arent all these
