Redundant Array of Independent Disks (RAID) technology is becoming a standard feature of computer systems that support mission-critical services like file sharing, mail exchange, or Web servers. RAID offers two benefits to these essential systems: improved I/O performance and fail-safe data storage. Although bandwidth problems on networks are well documented, the internal data transfer bottleneck that exists at the hardware level in each system can also leave you with perplexing performance issues. RAID is a cost-effective and easy-to-manage way to alleviate this bandwidth problem by distributing the I/O load seamlessly across multiple disks and controllers. RAID also provides uninterrupted data access through disk mirroring and parity algorithms. That means systems can remain online even during a disk or controller failure. RAID is scalable, making it robust enough for large, high-traffic sites and small, critical systems. By using RAID, system administrators can combine single disks into terabytes worth of data storage. Managing RAID on Linux covers everything system administrators need to know to put together a system that can support RAID. You will learn about the different types of RAID, along with associated technologies and issues, and how to choose the best RAID system for your needs. With a step-by-step, hands-on approach, the author guides you through the installation of either Linux software RAID or a hardware RAID card. The book shows how to build an array and optionally install a high-performance file system. Contents include: An introduction to RAID and Linux Planning and architecture of your RAID system Building a software RAID Software RAID tools and references Building a hardware RAID Performance and tuning of your RAID system RAID has become the low-cost solution of choice to deal with the ever-increasing demand for data storage space. Written for system administrators, power users, tech managers, and anyone who wants to learn about RAID technology, Managing RAID on Linux sidesteps the often-confusing vendor-specific approach you'll find elsewhere to give you the straight story on RAID. Even non-Linux users will find this book full of valuable material.

Java and databases make a powerful combination. Getting the two sides to work together, however, takes some effort--largely because Java deals in objects while most databases do not. This book describes the standard Java interfaces that make portable object-oriented access to relational databases possible and offers a robust model for writing applications that are easy to maintain. It introduces the JDBC and RMI packages and uses them to develop three-tier applications (applications divided into a user interface, an object-oriented logic component, and an information store). The book begins with a quick overview of SQL for developers who may be asked to handle a database for the first time. It then explains how to issue database queries and updates through SQL and JDBC. It also covers the use of stored procedures and other measures to improve efficiency, where these are available. But the book's key contribution is a set of patterns that let developers isolate critical tasks like object creation, information storage and retrieval, and the committing or aborting of transactions. The second edition includes more basics of JDBC and SQL, with more examples, and a deeper discussion about the architecture of a robust, maintainable database application. The second edition also explains the relationship between JDBC and Enterprise JavaBeans.

There is a serious information gap for Webmasters learning client-side JavaScript skills and trying to solve common Web-related problems. Knowing the syntax is one thing, being able to build a useful application is another. And while there are dozens of "how- to" JavaScript books available, few literally hand the Webmaster a set of ready-to-go, client-side JavaScript applications with thorough documentation that enable the reader to fully understand and extend those applications. By providing such a set of applications, JavaScript Application Cookbook allows Webmasters to immediately add extra functionality to their Web sites. This book targets readers with two different skill sets. The primary target is JavaScript-knowledgeable Webmasters and designers who can immediately begin constructing their own versions of the applications. The secondary target is those with little or no JavaScript experience. The included applications are ready for immediate use and require little customization. This book explores both the code and the techniques that are centered around core JavaScript functionality, a functionality that will not become incompatible or obsolete. The source file design of most applications and libraries will help modularize reader Web sites and facilitate easier site management and coding practices. Chapters are organized by application. Among the included applications are: * A client-side search engine that will show coders how to build their own search engine and get excellent results, all with a client-side tool * A drag-and-drop greeting application that lets users custom build and send DHTML email greetings * A GUI image rollover tool that generates cross-browser image rollover code for all versions of JavaScript * A robust client-side shopping cart application that lets shoppers browse and shop, while the application keeps a tab of the shopper's selections and a running bill, including tax and shipping * An online test application that auto-administers, grades, and displays answers to online exams or surveys An additional value to this book is an online resource (http://www.serve.com/hotsyte/) that discusses the applications and points to other resources. With its focus on providing practical real-world solutions for Webmasters, JavaScript Application Cookbook is destined to become a staple for every JavaScript developer, regardless of experience.

Oracle database administration requires a vast amount of information and an ability to perform a myriad of tasks--from installation to tuning to network troubleshooting to overall daily administration. Oracle provides many tools for performing these tasks; the trick is knowing what tool is right for the job, what commands you need to issue (and when), and what parameters and privileges you need to set. And, as every DBA knows, you need to know how do all this under pressure, while you face crisis after crisis. This book provides a concise reference to the enormous store of information an Oracle DBA needs every day (as well as what's needed only when disaster strikes). It's crammed full of quick-reference tables, task lists, and other summary material that both novice and expert DBAs will use time and time again. It covers the commands and operations new to Oracle8, but also provides Oracle7 information for sites still running earlier versions. Oracle Database Administration provides two types of material: DBA tasks--chapters summarizing how to perform critical DBA functions: installation, performance tuning, preventing data loss, networking, security and monitoring, auditing, query optimization, and the use of various Oracle tools and utilities DBA reference--chapters providing a quick reference to the Oracle instance and database, the initialization (INIT.ORA) parameters, the SQL statements commonly used by DBAs, the data dictionary tables, the system privileges and roles, and the SQL*Plus, Export, Import, and SQL*Loader syntax The book also includes a resource summary with references to additional books, Web sites, and other online and offline resources of special use to Oracle DBAs. Oracle Database Administration is the single essential reference you'll turn to again and again. If you must choose only one book to use at the office, keep at home, or carry to a site you're troubleshooting, this will be that book.

A 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.

System administrators often spend a great deal of time managing configuration information located on many different machines: usernames, passwords, printer configurations, email client configurations, and network filesystem configurations, to name a few. LDAPv3 provides tools for centralizing all of the configuration information and placing it under your control. Rather than maintaining several administrative databases (NIS, Active Directory, Samba, and NFS configuration files), you can make changes in only one place and have all your systems immediately "see" the updated information. Practically platform independent, this book uses the widely available, open source OpenLDAP 2 directory server as a premise for examples, showing you how to use it to help you manage your configuration information effectively and securely. OpenLDAP 2 ships with most Linux distributions and Mac OS X, and can be easily downloaded for most Unix-based systems. After introducing the workings of a directory service and the LDAP protocol, all aspects of building and installing OpenLDAP, plus key ancillary packages like SASL and OpenSSL, this book discusses: configuration and access control; distributed directories - replication and referral; using OpenLDAP to replace NIS; using OpenLDAP to manage email configurations; using LDAP for abstraction with FTP and HTTP servers, Samba, and Radius; interoperating with different LDAP servers, including Active Directory; and programming using Net::LDAP.

Programming on the Web today can involve any of several technologies, but the Common Gateway Interface (CGI) has held its ground as the most mature method--and one of the most powerful ones--of providing dynamic web content. CGI is a generic interface for calling external programs to crunch numbers, query databases, generate customized graphics, or perform any other server-side task. There was a time when CGI was the only game in town for server-side programming; today, although we have ASP, PHP, Java servlets, and ColdFusion (among others), CGI continues to be the most ubiquitous server-side technology on the Web. CGI programs can be written in any programming language, but Perl is by far the most popular language for CGI. Initially developed over a decade ago for text processing, Perl has evolved into a powerful object-oriented language, while retaining its simplicity of use. CGI programmers appreciate Perl's text manipulation features and its CGI.pm module, which gives a well-integrated object-oriented interface to practically all CGI-related tasks. While other languages might be more elegant or more efficient, Perl is still considered the primary language for CGI. CGI Programming with Perl, Second Edition, offers a comprehensive explanation of using CGI to serve dynamic web content. Based on the best-selling CGI Programming on the World Wide Web, this edition has been completely rewritten to demonstrate current techniques available with the CGI.pm module and the latest versions of Perl. The book starts at the beginning, by explaining how CGI works, and then moves swiftly into the subtle details of developing CGI programs. Topics include: * Incorporating JavaScript for form validation * Controlling browser caching * Making CGI scripts secure in Perl * Working with databases * Creating simple search engines * Maintaining state between multiple sessions * Generating graphics dynamically * Improving performance of your CGI scripts

Cisco routers are used widely both on the Internet and in corporate intranets. At the same time, the Cisco Internet Operating System (IOS) has grown to be very large and complex, and Cisco documentation fills several volumes. Cisco IOS Access Lists focuses on a critical aspect of the Cisco IOS--access lists. Access lists are central to the task of securing routers and networks, and administrators cannot implement access control policies or traffic routing policies without them. Access lists are used to specify both the targets of network policies and the policies themselves. They specify packet filtering for firewalls all over the Internet. Cisco IOS Access Lists covers three critical areas: *Intranets. The book serves as an introduction and a reference for network engineers implementing routing policies within intranet networking. * *Firewalls. The book is a supplement and companion reference to books such as Brent Chapman's Building Internet Firewalls. Packet filtering is an integral part of many firewall architectures, and Cisco IOS Access Lists describes common packet filtering tasks and provides a "bag of tricks" for firewall implementers. *The Internet. This book is also a guide to the complicated world of route maps. Route maps are an arcane BGP construct necessary to make high level routing work on the Internet. Cisco IOS Access Lists differs from other Cisco router titles in that it focuses on practical instructions for setting router access policies. The details of interfaces and routing protocol settings are not discussed.
