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.
