This book is for anyone who uses the CICS-IMS Database Control interface, referred to as DBCTL in the rest of this book.
This book is intended to help you understand DBCTL. It contains guidance on evaluating, installing, and using DBCTL. This book also discusses migration from local DL/I.
For programming information on programming interfaces provided by IMS™, see the IMS Application Programming: EXEC DLI Commands manual and the IMS Application Programming: DL/I Calls manual manuals.
The aim of this book is to give introductory and guidance information on evaluating, installing, and using DBCTL.
This book is intended to be used in conjunction with existing manuals in the CICS® and IMS libraries, to which it refers where appropriate.
Before you read this book, you need a general understanding of CICS and IMS. You can find general introductory information in the CICS Family: General Information and the General Information manual manual. You should also have some knowledge of the concepts of data management and databases. For guidance on these topics, see the IMS Database Administration Guide or the IMS Administration Guide: Database Manager.
Aspects of DBCTL, from installation through performance considerations, are presented in the order in which you are likely to need them. However, new users of DL/I should skip Migration considerations for DBCTL.
In general, this book refers to Customer Information Control System and Information Management System as "CICS" and "IMS", respectively. CICS used without qualification normally refers to the CICS element of CICS Transaction Server for z/OS®. However, when it is necessary to distinguish between particular CICS or IMS products, there are the following abbreviations, with a version and release number where appropriate:
