Preface

What this book is about

This book contains guidance about determining your CICS® recovery and restart needs, deciding which CICS facilities are most appropriate, and implementing your design in a CICS region.

The information in this book is generally restricted to a single CICS region. For information about interconnected CICS regions, see the CICS Intercommunication Guide.

This manual does not describe recovery and restart for the CICS front end programming interface. For information on this topic, see the CICS Front End Programming Interface User's Guide.

Who should read this book

This book is for those responsible for restart and recovery planning, design, and implementation—either for a complete system, or for a particular function or component.

What you need to know to understand this book

To understand this book, you should have experience of installing CICS and the products with which it is to work, or of writing CICS application programs, or of writing exit programs.

You should also understand your application requirements well enough to be able to make decisions about realistic recovery and restart needs, and the trade-offs between those needs and the performance overhead they incur.

How to use this book

This book deals with a wide variety of topics, all of which contribute to the recovery and restart characteristics of your system.

It’s unlikely that any one reader would have to implement all the possible techniques discussed in this book. By using the table of contents, you can find the sections relevant to your work. Readers new to recovery and restart should find the first section helpful, because it introduces the concepts of recovery and restart.
