This book is designed to cover three objectives. One, to provide a comprehensive resource to individuals (including novice, IT/Non-HP-UX administrators, HP-UX administrators) who intend to take the Certified System Administrator for HP-UX certification exam and pass it. Two, to provide a quick and valuable on-the-job resource to HP-UX administrators, administrators of other UNIX operating system software, IT managers, programmers, and DBAs working in the HP-UX environment. Three, to provide an easy-to-understand guide to novice and IT/non-HP-UX administrators who intend to learn HP-UX from the beginning. This book contains 33 chapters. The book is organized in such a way that it helps its audience understand concepts, implementation procedures, some basic troubleshooting, command syntax, configuration files, and daemons involved. There are three key areas: UNIX fundamentals, HP-UX system administration, and HP-UX network administration. 1.UNIX Fundamentals covers the basics of UNIX. Most information is not specific to a particular UNIX flavor, but rather includes general UNIX concepts, file manipulation and security techniques, shell and awk programming, vi editor, basic commands, and other topics. Chapters 01 through 06 and chapter 21 cover this area. Unlike many other similar books, a chapter on shell scripting is presented after covering HP-UX System Administration chapters. This is done intentionally to provide readers with some practical examples based on the knowledge they have gained from UNIX Fundamentals and HP-UX System Administration chapters. 2.HP-UX System Administration covers the HP-UX-specific system administration concepts and topics including HP-UX installation methods; software and patch management; user and group account administration; disk and device file management; LVM and file system administration; swap space and printer management; system startup and shutdown procedures; kernel reconfiguration techniques; backup, restore, and system recovery functions; job automation and process control; system logging and performance monitoring; and so on. Chapters 07 through 20 cover this area. 3.HP-UX Network Administration covers HP-UX network administration concepts and topics such as OSI and TCP/IP models; network hardware overview; LAN card administration; IP subnetting and routing techniques; network troubleshooting tools; system startup services; naming services such as DNS, NIS, and LDAP; File sharing tools viz. NFS and AutoFS; Time synchronization using NTP; internet services administration; BootP/TFTP services; system security; and so on. Chapters 22 through 33 cover this area. The beginning of each chapter highlights objectives covered. The end of each chapter includes a summary as to what is learnt in the chapter. Throughout the book tables, figures, screen shots, and examples are given to explain concepts and tasks. The output generated as a result of running commands is highlighted in light grey background to differentiate it with surrounding text. The book includes several appendices one of which contains more than 550 practice exam questions. Tables of commands, important files, and service daemons are included in separate appendices.

Getting Started with OpenVMS System Management gives new VMS system managers a jumpstart in managing this powerful and reliable operating system. Dave Miller describes the essentials of what an OpenVMS System Manager will have to manage. He defines areas of OpenVMS System Management and describes why each is important and how it fits into the larger management task. Even though some OpenVMS management concepts are unique (for instance quotas), many concepts (such as account creation) have counterparts in UNIX and Windows NT. So, wherever possible, Miller points out to his readers the parallel to other systems.
The book is intended as a precursor to Baldwin's OpenVMS System Management Guide and various OpenVMS documents. Thus it refers the reader to other books for the detailed management steps. Getting Started with OpenVMS System Management is a great introduction to the material Steve Hoffman and Dave Miller are revising for the OpenVMS System Management Guide, 2E.
-Permits experienced system managers to begin managing OpenVMS more quickly
-Dovetails with other Digital Press publications for easier reference by the OpenVMS manager
-Points you in the right direction for the complete documentation on each issue
-BONUS FEATURE! Includes excerpts from five key DP OpenVMS books

* Deals with powerful concepts in a simple way * Highlights important characteristics of Operating systems and other abstract entities in a new way * Explores the tenets of the UNIX operating system philosophy
Unlike so many books that focus on how to use UNIX, The UNIX Philosophy concentrates on answering the questions: Why use UNIX in the first place?'. Readers will discover the rationale and reasons for such concepts as file system organization, user interface and other system characteristics. In an informative, non-technical fashion, The UNIX Philosophy explores the general principles for applying the UNIX philosophy to software development. This book describes complex software design principles and addresses the importance of small programs, code and data portability, early prototyping, and open user interfaces. The UNIX Philosophy is a book to be read before tackling the highly technical texts on UNIX internals and programming. Written for both the computer layperson and the experienced programmer, this book explores the tenets of the UNIX operating system in detail, dealing with powerful concepts in a comprehensive, straightforward manner.

OpenVMS professionals have long enjoyed a robust, full-featured operating system running the most mission-critical applications in existence. However, many of today's graduates may not yet have had the opportunity to experience it for themselves. Intended for an audience with some knowledge of operating systems such as Windows, UNIX and Linux, Getting Started with OpenVMS introduces the reader to the OpenVMS approach.

Part 1 is a practical introduction to get the reader started using the system. The reader will learn the OpenVMS terminology and approach to common concepts such as processes and threads, queues, user profiles, command line and GUI interfaces and networking. Part 2 provides more in-depth information about the major components for the reader desiring a more technical description. Topics include process structure, scheduling, memory management and the file system. Short sections on the history of OpenVMS, including past, present, and future hardware support (like the Intel Itanium migration), are included. OpenVMS is considered in different roles, such as a desktop system, a multi-user system, a network server, and in a combination of roles.
Allows the more advanced reader some meaty content yet does not overwhelm the novice
Provides practical examples showing that OpenVMS is well-suited for popular modern applications
Gives a high-level overview of concepts behind internals such as memory management

UNIX for OpenVMS Users, 3E, makes it easy to see what OpenVMS and UNIX have in common, and to transfer your knowledge and experience in OpenVMS over to the world of UNIX.
Since most shops rely on more than one operating system, it is critical for system administrators and managers to understand the similarities and differences between platforms, so they can easily work in both environments while taking full advantage of the tools and applications available on each. This book offers OpenVMS professionals a concise source of information, so that they can quickly bring their expertise to bear on UNIX file management, e-mail, networking, and security.
This new edition of the book is enhanced with updated references to VMS, incorporates suggestions made by readers of previous editions, and particularly, recognizes other UNIX implementations in addition to HP's Tru64.
-Includes extensive additions to the sections on VMS logical names, on the emacs editor, and on shell programming and Perl
-Describes the interfaces common to both operating systems, with appendices covering command and editor summaries
-Adds emphasis on Linux

Systems Software: Essential Concepts provides students with an accessible introduction to the knowledge and fundamentals that are necessary to understand software and hardware. The text also reviews implementation techniques to familiarize students with more complex software, such as operating systems and compilers, and prepare them to take more advance courses within the discipline. The book is divided into two key topical areas: compiler fundamentals and the basic mechanisms and data structures required to support operating systems. In the compiler section, students learn about the runtime environment, how to implement a scanner and a symbol table, and how to implement parsing and code generation for a virtual machine. To emphasize practical application, students are challenged to implement a small compiler. In the operating system domain, students gain an understanding of the interrupt mechanism, process and thread implementation, and process synchronization. Featuring a modern and practical approach, Systems Software is an ideal resource for courses in system programming, systems software, software development, and assembly language. It can also serve as a supplementary material for introductory operating system and compiler courses.

This two-part book puts the spotlight on how a real-time kernel works using Micrium's C/OS-III kernel as a reference. Part I includes an overview of the operation of real-time kernels, and walks through various aspects of C/OS-III implementation and usage. Part II provides application examples (using the versatile Renesas YRDKRX62N Evaluation Board, available separately) that enable readers to rapidly develop their own prototypes. This book is written for serious embedded systems programmers, consultants, hobbyists, and students interested in understanding the inner workings of a real-time kernel. C/OS-III is not just a great learning platform, but also a full commercial-grade software package, ready to be part of a wide range of products. C/OS-III is a highly portable, ROMable, scalable, preemptive real-time, multitasking kernel designed specifically to address the demanding requirements of today 's embedded systems. C/OS-III is the successor to the highly popular C/OS-II real-time kernel but can use most of C/OS-II 's ports with minor modifications. Some of the features of C/OS-III are:

Preemptive multitasking with round-robin scheduling of tasks at the same priority
Supports and unlimited number of tasks and other kernel objects

Unlike so many books that focus on how to use Linux, Linux and the Unix Philosophy explores the "way of thinking that is Linux" and why Linux is a superior implementation of this highly capable operating system.
This book is a revision and expansion of a computer science classic. Every chapter has been thoroughly updated with Linux coverage.
Linux and the Unix Philosophy falls squarely between the "softer" texts on iterative software design and project management and the "how-to" technical texts. Thus far, no one has come out with a book that addresses this topic, either in the Unix space or the Linux space. Linux and the Unix Philosophy covers the same ground as the first edition, while it also presents bold new ideas about Linux and Open Source.
.Concise list of philosophy tenets makes it a handy quick reference
.Anecdotal examples personalize the book for the reader
.Conversational style makes it easy and joyful to read"

Dealing with system problems from user login failures to server crashes--is a critical part of a system administrator's job. A down system can cost a business thousands of dollars per minute. But there is little or no information available on how to troubleshoot and correct system problems; in most cases, these skills are learned in an ad-hoc manner, usually in the pressure-cooker environment of a crisis. This is the first book to address this lack of information.
The authors (both experienced Tru64 UNIX support engineer for Compaq) systematically present the techniques and tools needed to find and fix system problems. The first part of the book presents the general principles and techniques needed in system troubleshooting. These principles and techniques are useful not only for UNIX system administrators, but for anyone who needs to find and fix system problems. After this foundation, the authors describe troubleshooting tools used in the UNIX environment. The remainder of the book covers specific areas of the Tru64 UNIX operating system in detail: listing common problems, their causes, how to detect them, and how to correct them. Each chapter includes a "Before You Call Support" section that details the most important things to check and correct before it's necessary to call Compaq technical support. The authors also include decision trees to help the reader systematically isolate particular problem types.
