Page: 7 / 26

Introduction
1. Overview of This Release
Red Hat Application Stack is a set of software components that have been tested and certified
to work together in an integrated fashion. Red Hat Application Stack is designed for dynamic
web applications for both the LAMP and Java platforms.
2. Installation Prerequisites
• Red Hat Application Stack V.1.2 has been tested and certified on Red Hat Enterprise Linux 4
U5 systems. It is not certified for use with earlier versions of Red Hat Enterprise Linux. Please
follow the separate instructions for installing Red Hat Enterprise Linux 4 before installing Red
Hat Application Stack V.1.2.
• Red Hat Application Stack V.1.2 is available for 32- and 64-bit Intel architectures only (i386
and x86_64).
• Red Hat Application Stack V.1.2 includes JBoss AS 4.2, for running web applications in a
standard middleware environment. Note that JBoss AS uses an embedded Tomcat and does
not require a stand-alone Tomcat. Before installing and running JBoss AS you will require a
working installation of Java 1.5. Currently Red Hat Application Stack is certified with the Sun
JVM 1.5.0 update 11 or later, and the latest BEA JVM available through RHN. Please refer to
Chapter 2, Configuring the Java Environment for instructions on configuring the Java
environment for JBoss AS.
• If you intend to use the production config (started by default), you will need atleast 1.5GB of
physical memory.
3. Package-specific Notes
In most cases, Red Hat Application Stack contains more recent versions of packages than
those that are included in Red Hat Enterprise Linux. Installing Red Hat Application Stack may
update/overwrite these packages. Please ensure you review the complete package list before
beginning the installation process.
