This IBM Redbooks publication describes how to run the IBM Java Virtual Machine for AIX and WebSphere Application Server V6.1 on IBM System p and the AIX 5L Operating Systems. In terms of provisioning, tuning and maintenance, it consolidates information from all of these areas into a single resource and explains how you can implement, tune, and utilize the unique features of the IBM POWER Systems platform, AIX, and WebSphere Application Server together for maximum optimization. The book is intended for UNIX system administrators, Java developers, infrastructure designers, J2EE architects, project managers, performance testers and anyone who runs WebSphere Application Server on System p and AIX. It may contain some information which you already know, and other information that is new to you, depending on your background. AIX system administrators may be expert in configuring logical partitions and advanced virtualization, but may gain an understanding from this book about how WebSphere deployment teams may be able to exploit the features of IBM POWER Systems and AIX. WebSphere infrastructure architects may already know exactly how they want their redundant systems to work, but might learn how AIX teams can provide two or three physical servers that provide all of the different levels of application services necessary for the entire application lifecycle environment.

In this IBM® Redbooks publication, we describe how to create scalable and highly-available solutions that incorporate only two of the WebSphere products for Telecom : the IBM WebSphere® Presence and the WebSphere XML Document Management Servers (XDMS) . IBM WebSphere products for Telecom is a set of service enablers that extend the IBM WebSphere Application Server to deliver full IP Multimedia Subsystem (IMS) standards-compliant platform for creation and delivery of next-generation telecommunications services. This book is structured into five parts: Part 1, " Introduction" - in this introductory part, we provide an overview of the IBM WebSphere Presence Server and XDMS Document Management Servers and describe the sample scenario that we use throughout this book to demonstrate availability and scalability. Part 2, " The base scenario" - in part 2 of the book, we provide an overview of the base environment for our sample scenario, which includes the architecture and topology. We also describe how to set up and configure the different components in the base environment. We conclude with the execution of test cases that validate the base environment. Part 3, " The High Availability (HA) scenario" - in part 3, we describe the enhancements to the base environment to make it highly available. We demonstrate fail-over processing following failure of servers in the environment. Part 4, " The scalable scenario" - in this part, we describe how to configure additional servers to make the highly available environm

This IBM® Redbook describes how to use WebSphere® DynaCache to improve the performance of WebSphere Commerce Web sites. Today's Web sites are a demanding mixture of static images surrounded by mini-shopping carts, e-marketing spots, and other eye-catching fragments, all of which change from view to view and user to user. Sites must be richly featured and personalized to attract customers – and they must deliver this content at a high level of performance as well. But the richness and personalization customers want is often the enemy of good Web site performance. DynaCache technology gives Web site developers a robust tool for achieving excellent Web site performance. It can be applied retrospectively to existing Web sites whose performance is not meeting the owning company's requirements. It is even better applied from the beginning of a J2EE™ Web project, and will yield performance gains well beyond those achieved at a comparable cost by adding more hardware or rewriting the solution. This book leads you through an explanation of what caching is, and what is special about caching Web sites. It then describes the capabilities offered by WebSphere DynaCache and how to most effectively make use of those capabilities. The discussion is enhanced by practical examples and tutorials to help you configure DynaCache and implement a sample WebSphere Commerce store. Finally, the book describes how to approach benchmarking for an online store, and how to quantify the effectiveness of a dynamic caching policy on

Operations Optimization enables application services to share a common pool of heterogeneous resources, resulting in the following: Better resource utilization Predictable and consistent attainment of application service levels Increased flexibility to respond to changing application demands Improved ability to manage complex and heterogeneous environments This IBM Redbooks publication will help you understand how WebSphere Extended Deployment Operations Optimization can improve the performance and reliability of your systems. It takes you through the steps required to implement Operations Optimization.

This IBM Redbook looks at scenarios for using WebSphere Extended Deployment V6.0.2 and outlines procedures and best practices for these scenarios. Scenarios for operations optimization, long-running application extenders, and data-intensive application extenders are included. This book focuses on process, design, and usage guidelines, complimenting the "how to" information found in Using WebSphere Extended Deployment V6.0 To Build an On Demand Production Environment, SG24-7153. In addition, the business grid (batch and compute-intensive) capabilities are covered extensively including how to and best practice information. This book applies to WebSphere Extended Deployment V6.0.2 only.

This IBM Redbook extends the material provided in the Using WebSphere Extended Deployment V6.0 To Build an On Demand Production Environment, SG24-7153 , by providing a z/OS-centric description of the On Demand Router (ODR) and the long-running application support provided with WebSphere Extended Deployment (XD) 6.0. This book demonstrates the additional value the ODR provides as it is integrated with the existing z/OS Workload Manager. It also describes the long-running application support now available on z/OS with XD 6.0 along with its relationship to the traditional z/OS batch facilities. This book describes an XD 6.0 installation into our existing ITSO High Availability WebSphere Network Deployment environment as well as step-by-step instructions that take you through the configuration of the ODRs and dynamic clusters. It presents the setting up of a long-running application environment in detail. It uses a sample scenario to demonstrate the integration of an ODR Service Policy with a corresponding WLM Service Policy and the resulting finer grained WLM workload classification that the ODR now makes possible. Additional scenarios take you through the deployment and execution of a long-running workload.

This IBM Redbook gives a broad understanding of IBM WebSphere Extended Deployment V6.0 , explaining the functions and features while helping you to design and create a solution for your own environment. The following techniques are explained in this book: - Using WebSphere Extended Deployment dynamic operations. - Distributing workload with the On Demand Router. - Using visualization options to display information about the environment. - Using WebSphere Partitioning Facility to achieve high-performance. - Using ObjectGrid in IBM WebSphere Extended Deployment V6.0 . - Adding non-WebSphere Extended Deployment servers to your topology. - Configuring a highly available Deployment Manager. - Using repository checkpoint/restore to save and restore your configurations. - Using Application Edition Manager to install and support application versions. This book also provides step-by-step instructions for implementing a sample, multiple-machine environment. We use this environment to illustrate most of the IBM WebSphere Extended Deployment V6.0 features.
