TPF 4.1 Dump Analysis

Overview
This 3 day course is designed to give a detailed introduction to dump analysis in a TPF 4.1 environment to TPF programmers who are familiar with IBM Assembler language and basic 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 sound working knowledge of both Assembler Programming and TPF. They should also be familiar with the concepts introduced by TPF 4.1, particularly in respect to address spaces and core block usage and management, although this can be covered if required.

Audience
Programmers who are required to be proficient in reading and analysing dumps from a TPF 4.1 system

Student Numbers
The maximum recommended student to instructor ratio is 12:1

Objectives
By the end of the course, the delegates will be able, with the aid of course notes to:

· Use the console logs to obtain the information required to produce a dump listing for a given system error.
· Identify the different Address Spaces used in TPF 4.1.
· List the different PSW's and their usage.
· Identify fields within the dump and interpret the contents of the dump
· With the aid of a description of why the given dump occurs, be able to determine the cause of a given dump.
