WebSphere software platform, WebSphere Application Server V5.1
reinforces its reputation as the premier Java and Web Services
technology-based application platform, integrating enterprise data and
transactions with the dynamic on demand business world. It offers a rich on
demand business application deployment environment with a set of
application services that includes transaction management, security,
clustering, performance availability, connectivity, and scalability. WebSphere
Application Server is designed for full Java 2 Platform, Enterprise Edition
(J2EE) V1.3 compatibility. It supports SDK 1.4 to meet the changing
requirements of on demand business.
WebSphere Application Server Version 4.0, Advanced Single Server
Edition (5733-WS4): This is a Java application server based on a
servlet-based engine that turns your existing Web server (IBM HTTP Server
for iSeries) into a Java Web application server. As the core element of the
Application Framework for e-business, Advanced Edition, single server option
is the foundation of the WebSphere application server family.
WebSphere Application Server Version 4.0, Advanced Edition
(5733-WA4): This is a powerful Java-based development and deployment
environment for on demand business applications. WebSphere Advanced
Edition provides support for scaling Web sites into security-enhanced,
transactional-based on demand business application sites. WebSphere
Advanced Edition provides Enterprise JavaBean (EJB) support for
host-based transactions, and offers sophisticated tools to simplify distributed,
component-based application development. The EJB architecture is
component-based for the development and deployment of server-based
business applications. It greatly simplifies the separation of business
applications from underlying system services.
To understand the IBM on demand business strategy for the iSeries server, and
the positioning of strategic WebSphere products, refer to WebSphere for IBM
Eserver iSeries Server Buying and Selling Guide, REDP-3646.
Note: The Commercial Processing Workload (CPW) and memory
configuration references listed for the WebSphere products described in this
chapter represent the recommended minimum requirements. Deployments
that must support many users, or require shorter response times, may require
additional resources. Use the IBM Eserver Workload Estimator to help in
sizing all system configurations:
