Where We Are: Seeing the Big Picture

• It’s easy to miss the big picture when you work with pieces of the puzzle

• Likewise, when you think about products and features, it’s easy to miss the big picture about TPF Software tools

What’s the Essence?

• More than a collection of parts…

• These products work with features you never think about..

• To form a comprehensiveTest Management SystemTPF/GI TPF/IDE

The Test Management System Kernel Is More Than A Debugger

• APM Server (daemon)– Security--User validation

• Worker machines– On-demand resources

• Debugger• Shared Memory Management

– Shared storage between workers– Reduces VM paging

• Fast IPL or Startup Management• TPF Simulator• CPU Management

– Use CPU only when transactions are running

– No CPU usage during idle state

VM/CMS High-Level Flow

• User connects through TPF/GI

• APM Server starts worker machine– ACF/RACF Logon is verified– The system is loaded using

Shared Memory

• During testing, CPU Manager minimizes use of CPU– Provides cost savings

• User disconnects– APM Server disposes of

worker machine automatically

Why Travel?

QUESTION:– Why not keep things the same?– Why not stay in the “same place” and keep

enhancing the Test Management System?

Why Travel?

TWO ANSWERS:1. Customers are moving to zTPF

• zTPF requires major changes to the base TPF product

• This requires major changes to the kernel of TPF Software’s test management system

2. TPF as an operating system is more stable• Because of this, we can rebuild the kernel and

potentially serve more TPF users

• Worker machines– On-demand resources

• Debugger• Shared Segment Management

– Shared storage between workers– Reduces VM paging

zTPF High-Level Flow

• User connects through zTPF/GI– VM Logon is verified

• APM Server starts Product Worker machine

• Product Worker– Validates accessibility– Connects to zTPF/VPARS– Acts as intermediary between

zTPF/GI and zTPF/VPARS– Responsible for file information

• User disconnects– Product worker goes away– zTPF/GI goes away

Overall Architecture

• Client/Server• Uses Worker Machines• Work distributed across 3

platforms– PC– Worker (VM)– zTPF

• zTPF– Execution of code to

be tested, viewed, etc.

Configuration

• Configuration information will be supplied by a combination of– configuration files– user exits (REXX

execs)– Etc.

User Product

System Project

User Configuration

• Resources (VPARS) user is allowed to get to

• Products user is allowed to access

• Terminal information for user

• User-level security• File information for user

– Where will his/her files reside (path information)

User Product

System Project

Product Configuration

• Authorization info about product, e.g. …– Product not valid on

Production

– Product valid only Read mode

• File information for Product-associated files – This is the path information

– Ex. For DF/Explorer – path for the panels

– Ex. For TPFGI – path for SV files

– Etc.

• Other

User Product

System Project

System Configuration

• System definition – Prod/Test/Private

• User limits (how many allowed for this VPARS)

• List of valid products authorized on this VPARS

• File Information – Where are panels – How to load – default – Where to get source – for SV

tracing – Etc.

• IP address of System (VPARS) – Port where TSS should listen

for requests

User Product

Project Configuration

• Project definitions • Other project info • Private/Public project • File information for

project – Will have path for

project files – Etc.

Assumptions

zTPF in Norm State

TPF Assumptions• Customer must have

automation to bring zTPF to NORM state

• Customer must have an IP address defined for that zTPF

• When zTPF comes up TSS (TPF Software Infrastructure Services) will automatically be activated – TSS would read the System

Configuration• TSS will bring up products that

are defined for that zTPF • Both TPF Debugger and our

debugger can run at the same time

zVM Assumptions

• Customer must install APM Server

• Customer must define Worker machines

• Customer needs to allocate unique Terminal Addresses for each user (user exits available – and will be called when the USER CONFIG file is being read)

• Customer responsible for these User Exits (REXX)

UserExits

TPF Control Program Changes

0• We are using the standard IBM user-exits

• We will ship E-type code and C-type code– C-type code will plug directly into IBM exits– E-type code will be our kernel and software

Loading Programs and Testing

If You Use TPF/Toolkit for Development…

• Programs must be moved to VPARS so they can be loaded– Edit, Compile, Transfer

• This is customer responsibility

• Path for Source– Customer provides source

path info through the Compiler or through Worker User Exits

• zTPFGI will have functions to – Display programs loaded by

user – Load a program for a specific

user – Fallback a program for a

specific user

Delivery Roadmap

• Version 1– Kernel running under

VM/VPARS– Debugger, APMServer, etc.

• Version 2– Faster startup or IPL– Shared Segment

Management

• Version 3– CPU management– Private VPARS for each

user
