gtpm1m07TPF V4R1 Migration Guide: 3.1 to 4.1


About This Book

This book is written for any IBM Transaction Processing Facility (TPF) customer who is migrating, or planning to migrate, from the IBM Transaction Processing Facility Version 3 Release 1 system (referred to as the TPF 3.1 system in the remainder of this book) to the IBM Transaction Processing Facility Version 4 Release 1 system (referred to as the TPF 4.1 system in the remainder of this book).

Note:
This book should be used as a planning guide and is subject to change.

This book describes changes between the TPF 3.1 system and the TPF 4.1 system, and provides general information to help you plan for your TPF system migration. It does not contain specific information about planning for your migration and it does not contain information about installing the TPF 4.1 system. See the TPF System Installation Support Reference and TPF System Generation for more information about installation and system generation.

Some changes do not require any action on your part. For example, if you currently use the TPF 3.1 system without modifications and plan to use the TPF 4.1 system without making any modifications, it may not be necessary for you to make any changes. However, if you did make modifications to the TPF 3.1 system and plan to make modifications to the TPF 4.1 system, or you want to take advantage of the new functions provided in the TPF 4.1 system, then it will be necessary for you to make changes.

In addition, other changes found in the TPF 4.1 system may require you to make changes to the following to ensure the continued availability of existing functions:

Although all of these changes are discussed in this book, required changes are the primary focus.

In this book, abbreviations are often used instead of spelled-out terms. Every term is spelled out at first mention followed by the all-caps abbreviation enclosed in parentheses; for example, Systems Network Architecture (SNA). Abbreviations are defined again at various intervals throughout the book. In addition, the majority of abbreviations and their definitions are listed in the master glossary in the TPF Library Guide.

How This Book is Organized

This book is organized by chapter, and includes an appendix and index.

Conventions Used in the TPF Library

The TPF library uses the following conventions:

Conventions Examples of Usage
italic

Used for important words and phrases. For example:

A database is a collection of data.

Used to represent variable information. For example:

Enter ZFRST STATUS MODULE mod, where mod is the module for which you want status.


bold Used to represent text that you type. For example:

Enter ZNALS HELP to obtain help information for the ZNALS command.

Used to represent variable information in C language. For example:

level

monospaced Used for messages and information that displays on a screen. For example:
    PROCESSING COMPLETED

Used for C language functions. For example:

    maskc

Used for examples. For example:

    maskc(MASKC_ENABLE, MASKC_IO);
bold italic Used for emphasis. For example:

You must type this command exactly as shown.

Bold underscore Used to indicate the default in a list of options. For example:

Keyword=OPTION1 | DEFAULT

Vertical bar | Used to separate options in a list. (Also referred to as the OR symbol.) For example:

Keyword=Option1 | Option2

Note:
Sometimes the vertical bar is used as a pipe (which allows you to pass the output of one process as input to another process). The library information will clearly explain whenever the vertical bar is used for this reason.
CAPital LETters Used to indicate valid abbreviations for keywords. For example:

KEYWord=option

Scale Used to indicate the column location of input. The scale begins at column position 1. The plus sign (+) represents increments of 5 and the numerals represent increments of 10 on the scale. The first plus sign (+) represents column position 5; numeral 1 shows column position 10; numeral 2 shows column position 20 and so on. The following example shows the required text and column position for the image clear card.
|...+....1....+....2....+....3....+....4....+....5....+....6....+....7...
 
LOADER   IMAGE CLEAR
 

Notes:

  1. The word LOADER must begin in column 1.

  2. The word IMAGE must begin in column 10.

  3. The word CLEAR must begin in column 16.
