About This Book

This book contains general information about Version 5.2 of the following IBM DB2 Connect products, formerly known as Distributed Database Connection Services (DDCS):

DB2 Connect Personal Edition, formerly known as DDCS Single-User.
DB2 Connect Enterprise Edition (EE), formerly known as DDCS Multi-user Gateway, for AIX, HP-UX, SCO, Solaris, OS/2, and Windows NT.

This book is intended for programmers and administrators who are responsible for setting up and maintaining DB2 Connect connections between DB2 Universal Database clients and any of the following DRDA application server database management systems:

DATABASE 2 for OS/390 (DB2 for OS/390) Version 5 or higher
DATABASE 2 for MVS (DB2 for MVS) Version 3 or higher
DATABASE 2 for VSE and VM (DB2 for VSE & VM)
DATABASE 2 for AS/400 (DB2 for AS/400)
Any other relational database management system that implements Distributed Relational Database Architecture (DRDA) application server function.

Notes:

DB2 Universal Database Version 5 does not require DB2 Connect in order to allow host applications to access DB2 UDB data.
DB2 for OS/390 Version 5.1 or higher is required in order to use DRDA Level 3 functions, including TCP/IP database connections, and stored procedures with multi-row answer sets.
DB2 for OS/390 Version 6.1 or higher is required in order to use the DRDA Level 4 functions for which support is provided in DB2 Connect Version 5.2. These include: support for big integer, large object, row ID, and user-defined distinct data types, as well as two-phase commit support for XA applications over TCP/IP connections (DB2 Connect EE only).
For a complete list of the new functions delivered in DB2 Connect Version 5.2, please refer to "What's New in DB2 Connect Version 5.2?".

This book explains concepts that are applicable to both DB2 Connect products. For information about a specific platform refer to either:

DB2 Connect Personal Edition Quick Beginnings, for single-user DB2 Connect setup on OS/2, Windows 3.1, Windows 3.11 for Workgroups, Windows 95, or Windows NT.
DB2 Connect Enterprise Edition Quick Beginnings, for multi-user DB2 Connect gateway setup on AIX, HP-UX, OS/2, SCO, Solaris, or Windows NT.

This book also describes features of IBM DB2 Connect products and provides general information about setting up connections to DRDA server databases. In order to fully understand the configuration and communication protocols, you should be familiar with Systems Network Architecture (SNA) protocols, TCP/IP, DRDA, and your DRDA server operating system.

DB2 Connect is part of the DB2 Universal Database family of products.
