The must-have performance guide for every HP-UX administrator and developer, completely updated for HP-UX 11i.
° Introduces the best UNIX and HP-UX specific tools for performance managementand demonstrates practical ways to instrument HP-UX systems so that measurements truly represent real-world performance.
° The only official publication focusing on performance in the HP-UX 11i operating environment.
° Written by experts at Hewlett Packard specializing in HP-UX Performance.
Maximizing the performance of Unix systems is a challenge that requires a specialized understanding of operating system behavior and an intimate acquaintance with system tools that assist in tuning. This book helps sysadmins, net admins, developers, and capacity planners maximize the performance of HP-UX systems, resolve bottlenecks, and design applications for maximum performance. HP-UX 11i Tuning and Performance takes the guesswork out of maximizing HP-UX performance. It provides a comprehensive, systematic performance management methodology that addresses every stage in the lifecycle of an HP-UX system. Three of HP's leading performance experts present specific metrics, symptoms, and solutions for each key element of an HP-UX system, including hardware, the OS platform, and application development. This edition is completely updated with the many new processor and system families that use HP-UX since the first edition appeared in 1999. This book introduces the best generic UNIX and HP-UX specific tools for performance management and demonstrates practical ways to instrument HP-UX systems so that your measurements truly represent real-world performance. This new edition also takes into account the latest processors, systems, storage devices, I/O connections, new and changed software tools, new HP-UX features, high availability environments, and Java on HP-UX.
