Users of IBM® z/OS® for the past several years had a choice of two HTTP Servers that they can use. Now, one server became strategic while the other is no longer supported with z/OS V2.2. IHS powered by Apache supports IPv6 and 64-bit execution and includes security authentication and authorization capabilities that are similar to those capabilities that are provided in IHS powered by IBM Domino®. This IBM RedpaperTM publication is aimed at technicians who are responsible for planning and deploying system software. It provides informationon about the various features that are available in IBM HTTP Server powered by Apache. It also provides guidance about how to upgrade from the old product to the new product.

This IBM® Redbooks® publication helps you to become familiar with the technical changes that were introduced into the Availability Management areas with IBM z/OS® V2R2. This book is one of a series of IBM Redbooks that take a modular approach to providing information about the updates that are included with z/OS V2R2. This approach has the following goals: - Provide modular content - Group the technical changes into a topic - Provide a more streamlined way of finding relevant information that is based on the topic We hope you find this approach useful and we welcome your feedback.

This IBM® Redbooks® publication helps you plan and execute the migration of J2EE applications developed for Oracle WebLogic Server, JBoss, GlassFish, and Apache Tomcat, so that they run on WebSphere® Application Server V7. This book provides detailed information to plan migrations, suggested approaches for developing portable applications, and migration working examples for each of the platforms from which we migrated. It is not our intention to provide a feature-by-feature comparison of these application servers versus WebSphere Application Server V7, or to argue the relative merits of the products, but to produce practical technical advice for developers who have to migrate applications from these vendors to WebSphere Application Server V7. The book is intended as a migration guide for IT specialists who are working on migrating applications written for other application servers to WebSphere Application Server V7.
