There are some potential limitations and considerations that must be carefully weighed when deciding whether to serve static content from the WebSphere Application Server when esiEnable is set to true.

WebSphere for z/OS is a complex product made up of many components, similar to the human body. And, like the human body, WebSphere for z/OS can experience problems that need to be diagnosed and corrected. If a WebSphere for z/OS problem occurs, this IBM Redpaper can help you to determine what happened and why it happened. We first introduce you to the general problem determination methodology, then show you how to diagnose various problem symptoms encountered in a WebSphere for z/OS environment. We use flow charts that guide you through the analysis process in a step-by-step approach. Based on tasks you need to do and answers that you give to a series of questions designed to filter out irrelevant facts we attempt to take you to the problem area. If solutions exist to your errors or exceptions, we suggest them. We also mention analysis tools and reference information sources related to the symptoms. When no feasible solution is apparent, you are directed to prepare documentation and contact IBM. This Redpaper is intended for system programmers and administrators working with WebSphere Application Server for z/OS V6. It is targeted toward those who need to identify problems, analyze them, and fix them efficiently so that they can deliver good support for the WebSphere environment. Another objective is to assist IBM support and technical professionals as well as Java developers who work in this environment.

In this IBM Redpaper, we first introduce Web analytics: the context, the main concepts, and the common characteristics of the available tools. Then we explain how to exploit these tools to improve various points in the development and the quality assurance of a Web application, namely client compatibility, user navigation, robustness, bandwidth sizing, development, load-test plans, maintenance, and fat-client extensions. Finally, we describe a few problems and give some insights for solutions. This paper focuses on J2EE Web applications, because J2EE is the programming model implemented in IBM WebSphere Application Server. Yet, the methods presented can be applied to any Web application technology, such as ASP, PHP, or CGI.

Many enterprises, both large and small, are focused on increasing their business flexibility while simplifying their IT infrastructure in order to better meet their business objectives. The IBM On Demand Operating Environment defines a set of integration and infrastructure management capabilities that enterprises can use to achieve these challenging objectives. The On Demand Operating Environment feature of particular relevance to this Redpaper is the use of a service-oriented architecture (SOA). Using an SOA is necessary to achieve the goals of increased business flexibility and a simplified IT infrastructure. Many of these enterprises are determined to use proven architectures, designs, and product mappings in order to speed their implementation and minimize their risk. This Redpaper describes how to use the DVD entitled "Service Orientation Test-Drive with Linux on xSeries" that accompanies the paper. This paper focuses on a simple infrastructure to exploit service orientation principles. The intent of this environment is to allow companies to evaluate the processes and questions that arise from SOA projects, and take into consideration aspects such as the impact on the underlying system infrastructure. The information provided by this Redpaper and additional materials will help you get off to a fast start with SOA by providing an easy platform to install the basic software building blocks that can allow companies to experiment with service orientation principles.

This Redpaper is intended for system programmers and administrators who need an efficient way to identify problems, analyze them, and fix them so that they can deliver good support for the WebSphere Application Server for z/OS environment. IBM support and technical professionals and Java developers who work in the WebSphere for z/OS environment are also part of this targeted audience. We identified possible problem areas that can be encountered in WebSphere for z/OS and arranged them into four specific problem phases corresponding to steps in the WebSphere for z/OS life cycle: Phase 1: Installation, configuration and migration Phase 2: Application deployment Phase 3: Testing and running applications Phase 4: System environment (production) We give a general overview of the problem areas in the individual phases, explain how to analyze them, and provide valuable hints and tips for avoiding them.

For the day-to-day administration tasks for IBM WebSphere for z/OS, you need powerful and efficient tools for analyzing problems, for finding their root causes, and for solving them. This IBM Redpaper is intended to be a reference guide to the means and tools that can be used in the problem determination process for WebSphere for z/OS. In this paper, we introduce especially helpful commands for the WebSphere for z/OS environment; WebSphere for z/OS logs, traces and dumps; diagnostic tools for problem determination in WebSphere for z/OS; and other helpful tools. For each of these means, we provide information about its nature, explain when to use it, and demonstrate how to use it. We describe the output, show how to interpret it, and provide an example.

Welcome to the IBM eServer BladeCenter Business Express - Buying and Selling Guide. IBM has produced several of these guides for various IBM offerings, and they have become extremely popular with customers, Business Partners, and IBM employees. We named the guides "Buying and Selling," because it is clear that all the reasons a sales representative or Business Partner would sell an offering—value, differentiation, solution to customer business problems—are the same reasons why a customer would buy an offering. The broad target audience alone makes this guide very important: It provides one place to look for all. This guide is also unique because it is the first Buying and Selling Guide to focus on the complete IBM Express Portfolio, which is designed to better accommodate the needs of businesses that are looking for simple and cost-effective solutions to business problems. The purpose of this guide is to consolidate information from a variety of sources, so you do not have to search through dozens of resources to learn about the many ways IBM solutions can positively affect your business. It offers valuable information about definitions, events, information sources, education, technical assistance, frequently asked questions, services, finding a partner, support information, references, and much more. Let this consolidated reference (which is also easily found on the Web) be your one stop to help make the right decisions about the ways your business can be more successful—and how IBM Express Software can

This IBM Redpaper positions the Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM eServer BladeCenter and describes how it enhances the BladeCenter value proposition by seamlessly interfacing into a customer's existing data network. This paper helps you plan, install, and configure the Cisco Systems Intelligent Gigabit Ethernet Switch Module for several network topologies. Topology examples are provided to demonstrate several ways to perform the integration of the switch module into different networks. We also discuss the architecture of the Cisco Systems Intelligent Gigabit Ethernet Switch Module and BladeCenter and how the technology of each product jointly provides full interoperability into existing Cisco data centers. It is assumed that experienced systems and network administrators will use this paper to successfully integrate the Cisco Systems Intelligent Gigabit Ethernet Switch Module into their existing network. As we write this Redpaper, the Cisco Systems Intelligent Gigabit Ethernet Switch Module supports the 12.1(14) version of IOS. The switch also supports the 12.1(22) version. Check this support site on ibm.com for current information pertaining to the latest supported version of IOS: http://www.ibm.com/servers/eserver/support/bladecenter/index.html
