AIX Version 4.3 Differences Guide

Preface
This redbook focuses on the latest enhancements introduced in AIX Version
4.3.2. It is intended to help system administrators, developers, and users
understand these enhancements in order to evaluate potential benefits in their
own environments.
AIX Version 4.3 includes many new features, including 64-bit application support,
IP Version 6, X11 Release 6, Lightweight Directory Access Protocol (LDAP), and
improved scaling over a wider range of platforms. The availability of two new
Web-based utilities, Web-Based Systems Manager and a Web-based
Documentation Search Service, signal AIX’s move toward a standard, unified
interface for system tools. There are many other enhancements available with
AIX Version 4.3, and you can explore them all in this redbook.
This publication is an update to the previously published AIX Version 4.3
Differences Guide, First Edition, which focused on the enhancements introduced
in AIX Version 4.3.0. Certain sections of the First Edition have been removed, or
edited as required, to reflect the fact that the online documentation provided with
AIX Version 4.3 now adequately covers many of the original topics.
How this Redbook is Organized
Throughout this publication, each major section heading indicates which level of
AIX 4.3 introduced the enhancement by including the maintenance level in
parentheses. For example, the following section heading:
Multiple Concurrent Reads (4.3.1)
indicates that the feature was introduced in AIX Version 4.3.1. If no maintenance
level is given, then the feature was included in the initial AIX Version 4.3.0.
