Taylor & Francis Inc Quick Changeover for Operators: The SMED System
Book SynopsisThe powerful knowledge contained in this book can make your workplace more productive, your job simpler, and everything more satisfying. It's about how to do equipment or product changeovers in record time--often in less than 10 minutes. The method you'll learn here is called SMED, short for "Single-Minute Exchange of Die" (the "single" here means a single-digit number of minutes).Developed from a longer book, A Revolution in Manufacturing: The SMED System (cat no. PP9903), written for managers, this book is written for frontline production and assembly associates. It presents an overview of the reasons why SMED is important for companies and employees, sets out the three basic stages of SMED, and then devotes a separate chapter to each of these stages. The first chapter of the book is like an "owner's manual" that tells you how to get the most out of your reading time by using the margin assists, summaries, and other features of the book to help pull out exactly what you need. One of the most effective ways to use this book is to read and discuss it with other employees. The authors planned the book so that it can be used this way, organizing the book into chunks of information that can be covered in a series of short sessions. Each chapter includes reflection questions to stimulate group discussion. A Learning Package is also available (catalog no.PP7126), which includes a leader's guide, overhead transparencies to summarize major points, and color slides showing examples of SMED applications in different kinds of companies.

O'Reilly Media Managing NFS and NIS: Covers Nfs Version 3
Book SynopsisA modern computer system that's not part of a network is even more of an anomaly today than it was when we published the first edition of this book in 1991. But however widespread networks have become, managing a network and getting it to perform well can still be a problem. Managing NFS and NIS, in a new edition based on Solaris 8, is a guide to two tools that are absolutely essential to distributed computing environments: the Network Filesystem (NFS) and the Network Information System (formerly called the "yellow pages" or YP). The Network Filesystem, developed by Sun Microsystems, is fundamental to most Unix networks. It lets systems ranging from PCs and Unix workstations to large mainframes access each other's files transparently, and is the standard method for sharing files between different computer systems. As popular as NFS is, it's a "black box" for most users and administrators. Updated for NFS Version 3, Managing NFS and NIS offers detailed access to what's inside, including: * How to plan, set up, and debug an NFS network * Using the NFS automounter * Diskless workstations * PC/NFS * A new transport protocol for NFS (TCP/IP) * New security options (IPSec and Kerberos V5) * Diagnostic tools and utilities * NFS client and server tuning NFS isn't really complete without its companion, NIS, a distributed database service for managing the most important administrative files, such as the passwd file and the hosts file. NIS centralizes administration of commonly replicated files, allowing a single change to the database rather than requiring changes on every system on the network. If you are managing a network of Unix systems, or are thinking of setting up a Unix network, you can't afford to overlook this book.Trade Review"If you administrate a collection of Unix systems of any flavour then buy this book. There will always be something of interest that will make your Unix network easier to use and manage - guaranteed. If your network involves NT interconnectivity then still buy it but read the opinion on PCNFS verses SAMBA with an open mind." - Jon Wilks, Cvu, June 2002Table of ContentsPreface 1.

O'Reilly Media Lotus Domino Administration in a Nutshell
Book SynopsisDomino is one of the most effective platforms for developing and deploying e-business applications, allowing new communities of developers to enjoy its collaborative capabilities. With over 55 million seats worldwide, Domino already provided a strong foundation for messaging and web applications, and the release of R5 builds on that to make Domino easier to use than ever before. For example, Lotus Domino R5 has been expanded to interact with most browsers and other non-Notes clients, so developers can choose their favorite language to design web applications. With R5, administrators can centrally modify client configurations instead of hopping from one terminal to the next throughout the company. The new Domino interface allows administrators to visually monitor the health and status of the Domino servers in a network from a single screen. All this capability implies complexity, and it's easy to forget which menu to go to. Here's where Lotus Domino Administration in a Nutshell can help. It's a quick reference that will come in handy again and again for finding solutions to administrative problems. This book covers: * Domino architecture and key concepts * R5 administration tools * Domino directory and console commands * Database properties and Access Control * Configuring Domino Enterprise Connection Services (DECS) * Supporting the Notes client * Domino for IIS Whether the task is messaging servers, modifying administration tasks to a simpler and more efficient level, or ensuring the security and flexibility of a web application server, Lotus Domino Administration in a Nutshell is the reference developers need to make the most of this reliable and scalable integrated server platform.Table of ContentsPreface.

Book SynopsisEnterprise systems supporting business processes in large companies and organizations, are critical for their business survival, and expensive to build and run. This book describes successful approaches to designing, and tuning for performance, large enterprise systems. In contrast to earlier mainframes, the modern distributed systems contain large numbers of components and simple capacity planning methods, applicable to mainframes, cannot be used for design or tuning of complex distributed systems. Methods that have proven to be successful are based on building predictive models that take into account key characteristics of hardware, software, data and communications.

Nova Science Publishers Inc On-Line Monitoring Systems & Computer Tool
Book SynopsisThis book presents new results in the construction and methodology of tools to support the development of parallel programs. It focuses on tools for debugging and performance analysis. We can observe two major trends in recent years: on one hand, tool developers want to solve the problem of tool interoperability. This question is crucial for application developers as they want to apply different tools from different producers to their programs at the same time. An infrastructure that provides interoperability could allow us to see synergetic effects when using multiple tools, thus increasing the programmer''s productivity during implementation and testing. On the other hand, there are substantial efforts to automate parts of parallel program development. While this tool automation is not a new area, there remains much to be done. Parallel program development remains the domain of the expert and aficionado. This area continues to be an important one for the programmers and users of high performance computing.
