Configuration Guide 1

CHAPTER 1 Introduction

Sybase Adaptive Server Enterprise for UNIX is a full-featured Adaptive

Server that runs on the following platforms:

• HP-UX

•IBM AIX

•Sun Solaris

• Linux 32-bit

Note The instructions in this book assume that Adaptive Server is

installed and running. For information about installing and starting

Adaptive Server, as well as for an overview of Adaptive Server, see the

Adaptive Server Installation Guide for your platform.

This chapter provides an overview of how to configure Adaptive Server

and the steps you need to take to customize it for your use.

About Adaptive Server

Adaptive Server performs data management and transaction functions,

independent of client applications and user interface functions.
