Book Description
This guide presents a repeatable methodology for troubleshooting poorly performing applications. It is designed to help the network analyst focus on key network-visible behaviors that influence application performance, with the goal of identifying exactly where and why transaction delays occur—without the distraction of costly red herrings. In many cases, the methodology presented here is applied as a drill-down or deep-dive analysis from a symptom or fault domain identified by a complementary application or network monitoring solution, especially where ambiguity is unacceptable. In other cases it is applied independently, where performance problems may remain invisible to or undiagnosable by monitoring solutions. It is designed to address typical web or client/server business applications—the types where poor performance results in user complaints, diminished productivity and lost revenue opportunities. Perhaps most importantly, it highlights the tight interaction between network conditions, server configurations and application behaviors, understanding the critical importance of effective collaboration between network, system and application teams. The guide includes relevant TCP, network and application background, and while it references Dynatrace Network Analyzer as the tool example, the guide will be useful even without the product. I trust you will find this book useful and hope you enjoy reading it. Please feel free to contact me with questions, corrections, concerns, anecdotes, or suggestions. Gary Kaiser

Book Description
Coding and testing are often considered separate areas of expertise. In this comprehensive guide, author and Java expert Scott Oaks takes the approach that anyone who works with Java should be equally adept at understanding how code behaves in the JVM, as well as the tunings likely to help its performance. You’ll gain in-depth knowledge of Java application performance, using the Java Virtual Machine (JVM) and the Java platform, including the language and API. Developers and performance engineers alike will learn a variety of features, tools, and processes for improving the way Java 7 and 8 applications perform. Apply four principles for obtaining the best results from performance testing Use JDK tools to collect data on how a Java application is performing Understand the advantages and disadvantages of using a JIT compiler Tune JVM garbage collectors to affect programs as little as possible Use techniques to manage heap memory and JVM native memory Maximize Java threading and synchronization performance features Tackle performance issues in Java EE and Java SE APIs Improve Java-driven database application performance

Book Description
This IBM Redbooks publication provides IMS performance monitoring and tuning information. This book differs from previous IMS performance and tuning IBM Redbooks in that there is less emphasis on the internal workings of IMS and more information about why and how certain options can affect the performance of IMS. Most of the information in the previous book IMS Version 7 Performance Monitoring and Tuning Update, SG24-6404, is still valid, and in most cases, continues to be valid in any future versions of IMS. This book is not an update or rewrite but instead attempts to be more of a guide than a reference. As such, the team gathered experiences and data from actual production environments as well as from IBM benchmarks and solicited input from experts in as many areas as possible. You should be able to find valuable new information and perhaps validate things you might have questioned. Hardware and software characteristics are constantly changing, but hopefully the information that you find here provides a basis to help you react to change and to keep your IMS running efficiently. In this book, we introduce methods and tools for monitoring and tuning IMS systems, and in addition to IMS TM and DB system-wide performance considerations, we dedicate separate chapters for application considerations, IMS and DB2 interoperability, the Parallel Sysplex environment, and On Demand considerations.

Book Description
. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.

Book Description
Visitor participation is a hot topic in the contemporary world of museums, art galleries, science centers, libraries and cultural organizations. How can your institution do it and do it well? The Participatory Museum is a practical guide to working with community members and visitors to make cultural institutions more dynamic, relevant, essential places. Museum consultant and exhibit designer Nina Simon weaves together innovative design techniques and case studies to make a powerful case for participatory practice. "Nina Simon's new book is essential for museum directors interested in experimenting with audience participation on the one hand and cautious about upending the tradition museum model on the other. In concentrating on the practical, this book makes implementation possible in most museums. More importantly, in describing the philosophy and rationale behind participatory activity, it makes clear that action does not always require new technology or machinery. Museums need to change, are changing, and will change further in the future. This book is a helpful and thoughtful road map for speeding such transformation." -Elaine Heumann Gurian, international museum consultant and author of Civilizing the Museum "This book is an extraordinary resource. Nina has assembled the collective wisdom of the field, and has given it her own brilliant spin. She shows us all how to walk the talk. Her book will make you want to go right out and start experimenting with participatory projects." -Kathleen McLean, participatory museum designer and author of Planning for People in Museum Exhibitions "I predict that in the future this book will be a classic work of museology." --Elizabeth Merritt, founding director of the Center for the Future of Museums
