Never has something cried out for a cookbook quite as much as Cisco's Internetwork Operating System (IOS). IOS is powerful and flexible, but also confusing and daunting. Most tasks can be accomplished in several different ways. And you don't want to spend precious time figuring out which way is best when you're trying to solve a problem quickly. That's what this cookbook is for. Fortunately, most router configuration tasks can be broken down into several more or less independent steps: you configure an interface, you configure a routing protocol, you set up backup links, you implement packet filters and other access control mechanisms. What you really need is a set of recipes that show you how to perform the most common tasks, so you can quickly come up with a good configuration for your site. And you need to know that these solutions work: you don't want to find yourself implementing a backup link at 2 A.M. because your main link is down and the backup link you set up when you installed the router wasn't quite right. Thoroughly revised and expanded, "Cisco IOS Cookbook, 2nd Edition" adds sections on MPLS, Security, IPv6, and IP Mobility and presents solutions to the most common configuration problems, including: configuring interfaces of many types, from serial to ATM and Frame Relay; configuring all of the common IP routing protocols (RIP, EIGRP, OSPF, and BGP); configuring authentication; configuring other services, including DHCP and NTP; setting up backup links, and using HSRP to configure backup routers; managing the router, including SNMP and other solutions; and using access lists to control the traffic through the router. If you work with Cisco routers, you need a book like this to help you solve problems quickly and effectively. Even if you're experienced, the solutions and extensive explanations will give you new ideas and insights into router configuration. And if you're not experienced - if you've just been given responsibility for managing a network with Cisco routers - this book could be a job-saver.

This concise book contains detailed information about Oracle internals -- information that's not readily available to Oracle customers. It lays a foundation for advanced performance tuning of the Oracle database. Based on Oracle8i release 8.1, the book describes many of the secrets of Oracle's internal services: data structures, algorithms, and undocumented Oracle system statistics. Main topics include: Waits - how Oracle processes communicate via semaphores, and how to use the Oracle wait statistics to identify the source of performance problems. Latches - how they keep multiple processes from inspecting protected data structures at the same time, and how to examine and control latch behavior and statistics. Locks - how they work with latches to protect data structures (locks allow multiple sessions to share resources in some cases), and how locks affect performance. There is also a detailed discussion of instance locks, which are used in parallel server environments. Memory - how Oracle uses memory (e.g., the various elements of the System Global Area), and how Oracle dynamically allocates and manages memory. Oracle8i Internal Services is aimed especially at administrators and developers who need detailed internal information to do advanced performance tuning. The book will expand your repertoire of tuning solutions and troubleshooting techniques by explaining how you can use Oracle's hidden parameters and undocumented system statistics to best advantage. NOTE: The author has collected the scripts he has developed for tuning and analysis into a toolkit (known as APT, for Advanced Performance Tuning). These scripts access the Oracle X$ tables directly and provide information not otherwise available. The scripts are available to readers for free from the O'Reilly web site.

Since the dawn of creation, man has designed maps to help identify the space that we occupy. From Lewis and Clark's pencil-sketched maps of mountain trails to Jacques Cousteau's sophisticated charts of the ocean floor, creating maps of the utmost precision has been a constant pursuit. So why should things change now? Well, they shouldn't. The reality is that map creation, or "cartography," has only improved in its ease-of-use over time. In fact, with the recent explosion of inexpensive computing and the growing availability of public mapping data, map-making today extends all the way to the ordinary PC user. "Mapping Hacks", the latest page-turner from O'Reilly Press, tackles this notion head on. It's a collection of one hundred simple - and mostly free - techniques available to developers and power users who want draw digital maps or otherwise visualize geographic data. Authors Schuyler Erle, Rich Gibson, and Jo Walsh do more than just illuminate the basic concepts of location and cartography, they walk you through the process one step at a time. "Mapping Hacks" shows you where to find the best sources of geographic data, and then how to integrate that data into your own map. But that's just an appetizer. This comprehensive resource also shows you how to interpret and manipulate unwieldy cartography data, as well as how to incorporate personal photo galleries into your maps. It even provides practical uses for GPS (Global Positioning System) devices - those touch-of-a-button street maps integrated into cars and mobile phones. Just imagine: If Captain Kidd had this technology, we'd all know where to find his buried treasure! With all of these industrial-strength tips and tools, "Mapping Hacks" effectively takes the sting out of the digital map-making and navigational process. Now you can create your own maps for business, pleasure, or entertainment - without ever having to sharpen a single pencil.

A complete reference to AppleScript, the popular programming language that gives both power users and sophisticated enterprise customers the important ability to automate repetitive tasks and customize applications. As the Macintosh continues to expand and solidify its base in the multimedia and publishing industries, AppleScript is and important tool on this platform for creating sophisticated time- and money-saving workflow applications (applets). These applets automate the processing and management of digital video, imaging, print, and web-based material. AppleScript is also gaining a foothold in scientific programming, as technical organizations adopt G4 CPU-based systems for advanced computing and scientific analysis. Finally, "power users" and script novices will find that AppleScript is a great every-day Mac programming tool, similar to Perl on Windows NT or Unix. In this reference, AppleScript programmers will find: detailed coverage of AppleScript Version 1.4 and beyond on Mac OS 9 and Mac OS X; complete descriptions of AppleScript language features, such as data types, flow-control statements, functions, object-oriented features (script objects and libraries), and other syntactical elements; and descriptions and hundreds of code samples on programming the various "scriptable" system components, such as the Finder, File Sharing, File Exchange, Network scripting, Web scripting, Apple System Profiler, the ColorSync program, and the numerous powerful language extensions called "osax" or scripting additions. The book covers updates and improvements with practical, easy to understand tips, including using AppleScript as a tool for distributed computing, a development that Apple Computer calls "program linking over IP". Programmers can now do distributed computing with Macs over TCP/IP networks, including controlling remote applications with AppleScript and calling AppleScript methods on code libraries that are located on other machines. It also covers using the Sherlock find application to automate web and network searching and insights on scripting new Apple technologies such as Apple Data Detectors, Folder Actions, Keychain Access, and Apple Verifier.
