About Accelerating AIX: Performance Tuning For
Product Description Reengineering and Total Quality Management promised dramatic improvements in profit, efficiency, and quality, but a number of TQM initiatives ended in failure as a result of an incorrect or incomplete implementation process. Here is a book that will help put the odds on your side by giving you specific skills and experience-based advice for successfully planning and implementing process design. Comprehensive in scope, this book integrates the three major approaches to process redesign -- benchmarking, continuous improvement, and reengineering -- showing how to combine them for maximum effectiveness. It explains the circumstances for which each approach is appropriate and describes how to apply each specific technique effectively. The book also points out the many potential pitfalls that can impede even the most well thought out program. You will find detailed and methodical coverage of such topics as defining processes, measuring performance, reducing cycle times, team building, benchmarking, the critical success factors for reengineering, and much more. Numerous examples from many different industries demonstrate concepts and techniques in action, illustrate common mistakes, and provide a model for successful implementation that you can apply to your own organization. The information is presented in an accessible format, with guidelines, checklists, worksheets, discussion questions, and clear graphics to help you absorb essential information quickly and apply it successfully. From the Publisher As an AIX system administrator or programmer, you know that performance tuning is critical to ensuring that your operating system can meet the demands placed on today's computer systems and LAN operations. However, the methods of tuning have often been difficult to divine without expert assistance. In Accelerating AIX, Rudy Chukran shares his AIX know-how, experience and insight gained from spending over ten years as one of IBM's tuning experts. In this comprehensive book you will find information for both system administrators and application programmers with comprehensive coverage of monitoring, diagnostic, and development tools; remedies for performance slowdowns; techniques for relieving LAN bottlenecks; and proven methodologies for isolating, analyzing, and solving performance problems. A complete, one-stop reference, the book addresses topics such as: * AIX system design, emphasizing those areas where tuning is possible and most effective * System administration tools, including vmstat, iostat, sar, ps, AIX Monitor, Rmss, PDT, and more * CPU, memory, and disk-bound remedies, such as Schedtune, Time Slice, tuning memory overcommitment algorithm, and disk caching effects * LAN monitoring tools and remedies, including transmit and receive queues, send and receive buffers, MTU, Name Resolution, and Client and Server NFS Daemons. * Programming performance tools, such as XL compiler flags for numerous languages, dynamically and statically linked objects, various profilers, program visualizer, and techniques for implementing shared libraries * AIX system call remedies emphasizing interprocess communications and shared memory, for example, Pthread_mutex lock and unlock, Power PC Weak Memory Ordering, and Matrix Access Optimization Drawing on his years of practical experience with AIX, the author then shows you "what to do when..." in a special chapter that discusses how to recognize and evaluate problems and plan and implement appropriate solutions using many of the tools and techniques presented.
