Introduction:
The Problem
analysis and determination is a skill that can be applied to
any discipline. However, each discipline requires specific
activities that relate to that discipline alone. In computer
programming, there are certain actions that one must take
when analyzing a problem, if one wants to do so efficiently.
This course begins with the basics of problem analysis and
then focuses on analytical techniques particularly suited to
computer programming. The skills are studied in a
representative computing environment. This course uses the
OS/390 operating system to introduce the student to
programming analysis skills.
Because the course content is targeted to OS/390 application programmers
and end-users, it focuses on the aspects of OS/390 with which the
programmer and end-user come into greatest contact. In particular,
it focuses on the flow of work through an OS/390 system and the components
that make that flow possible. It covers the analysis of ABEND codes,
system messages and completion codes from both the OS/390 system and
some specific subsystems, such as JES 2 and CICS. This course provides
the programmer with the skills to take appropriate action in response
to these messages and codes.
Audience: All computer users (operators, programmers and
managers) who have a need to run programs in an OS/390
environment. This course is also applicable to production
control or help-desk personnel who need to debug jobs or
programs in an OS/390 environment.
Objectives: On completion of this course, the student
should be able to:
- interpret system
messages appearing in a job's message log
- interpret messages from selected
applications and subsystems
- take appropriate action to correct
a job in response to messages from OS/390 and selected subsystems
and applications
- interpret system ABEND
codes and take appropriate action to prevent the failure
from recurring
- locate and interpret the
return codes passed by selected applications
Prerequisites: The student must have a working knowledge of
data processing and computer fundamentals.
Duration:
This course is
2 days long.
