z/TPF Dump Analysis
Overview
This 3
day course is designed to give a detailed introduction to dump analysis
in a z/TPF environment to programmers who are familiar with IBM
Assembler language and basic z/TPF concepts, but have little or no
experience of reading dumps.
The course can be customised to individual customer requirements by
including customer dumps and listings in the notes and customer dumps
for the exercises.
Lectures throughout the course are supplemented by examples and are
interspersed with practical dump solving sessions.
Pre-requisites
Attendees should have a reasonable working knowledge of both Assembler
Programming and z/TPF.
Audience
Programmers
who are required to be proficient in reading and analysing dumps from a
z/TPF system. This class is also
suitable for staff who require a deeper understanding of the internals
of a z/TPF system
