    Abstract: This pocket reference provides quick-reference information that will help you use Oracle's PL/SQL language. It is a companion to Steven Feuerstein and Bill Pribyl's bestselling book, Oracle PL/SQL Programming , and includes coverage of the latest version of Oracle, Oracle8i. Oracle is the most popular database management system in use today, and PL/SQL plays a pivotal role in current and projected Oracle products and applications. PL/SQL provides procedural extensions to the SQL relational database language and to an ever-growing number of Oracle development tools. It offers a myriad of data types, and such features as cursors, loops, conditional and sequential control statements, exception handlers, records, tables, and constructs for developing modular code (functions, procedures, and packages). Originally a rather limited tool, PL/SQL became with Oracle7 a mature and effective language for developers. Now, with the introduction of Oracle8, PL/SQL has taken the next step towards becoming a fully realized programming language providing sophisticated object-oriented capabilities. The book on which this pocket reference is based, Oracle PL/SQL Programming , filled a huge gap in the Oracle market, providing developers with a single, comprehensive guide to building applications with PL/SQL -- and building them the right way. That book has become the bible for PL/SQL developers who have raved about its completeness, readability, and practicality. The book is packed with strategies, code architectures, tips, techniques, and fully realized code. The second edition of the book updated the text with the new Oracle8 PL/SQL features, including object types, collections, external procedures, and large object data types and functions. The pocket reference boils down the most vital information from the large (nearly 1000 pages) book into an accessible quick reference that summarizes the basics of PL/SQL -- its block structure, fundamental language elements (e.g., identifiers, declarations, defaults), data structures (including Oracle8 objects), and statements for program control, loops, exception handling, and database access. It also covers the the basics of using Oracle's procedures, functions, and packages, and the latest features for Oracle8i.

    Abstract: 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.

    Abstract: Any organization that uses the Oracle relational database management system (RDBMS) these days needs to use multiple databases. There are many reasons to use more than a single database in a distributed database system: Different databases may be associated with particular business functions, such as manufacturing or human resources. Databases may be aligned with geographical boundaries, such as a behemoth database at a headquarters site and smaller databases at regional offices. Two different databases may be required to access the same data in different ways, such as an order entry database whose transactions are aggregated and analyzed in a data warehouse. A busy Internet commerce site may create multiple copies of the same database to attain horizontal scalability. A copy of a production database may be created to serve as a development test bed. Tunability Platform autonomy Fault tolerance Scalability Location transparency Site autonomy Introduction to Distributed Database Systems SQL*Net and Net8 Configuration and Administration Distributed Database Security Designing the Distributed System Oracle's Distributed System Implementation Sample Configurations 8. Engineering Considerations Oracle Replication Architecture Advanced Replication Option Installation Basic Replication Multi-Master Replication Updateable Snapshots Procedural Replication Conflict Avoidance and Resolution Techniques In a distributed database environment, data in two or more databases is accessible as if it were in a single database. Usually, the different databases are on different servers, which may be located at the same site or a continent away. Communication between the servers takes place via SQL*Net (for Oracle7) or Net8 (for Oracle8). Distributed database environments offer a number of benefits over single- database systems, including: This book describes how you can use multiple databases and the distributed features of Oracle to best advantage.

Steven Feuerstein's Oracle PL/SQL Programming is a comprehensive guide to building applications with PL/SQL. That book has become the bible for PL/SQL developers who have raved about its completeness, readability, and practicality. Built-in packages are collections of PL/SQL objects built by Oracle Corporation and stored directly in the Oracle database. The functionality of these packages is available from any programming environment that can call PL/SQL stored procedures, including Visual Basic, Oracle Developer/2000, Oracle Application Server (for web-based development), and, of course, the Oracle database itself. Built-in packages extend the capabilities and power of PL/SQL in many significant ways. for example: DBMS_SQL executes dynamically constructed SQL statements and PL/SQL blocks of code. DBMS_PIPE communicates between different Oracle sessions through a pipe in the RDBMS shared memory. DBMS_JOB submits and manages regularly scheduled jobs for execution inside the database. DBMS_LOB accesses and manipulates Oracle8's large objects (LOBs) from within PL/SQL programs. 1.

    Abstract: The first thing users of the Linux operating system come face to face with is the shell. "Shell" is the UNIX term for a user interface to the system -- something that lets you communicate with the computer via the keyboard and display. Bash , the Free Software Foundation's "Bourne Again Shell," is the default shell for Linux, the popular free UNIX-like operating system. It's also a replacement for the standard UNIX Bourne shell, which serves both as a user interface and as a programming language. Like the FSF's other tools, bash is more than a mere replacement: it extends the Bourne shell in many ways. Features include command line editing, key bindings, integrated programming features, command completion, control structures (especially the select construct, which enables you to create menus easily), and new ways to customize your environment. Whether you want to use bash for its user interface or its programming features you will find Learning the bash Shell a valuable guide. The book covers all of bash 's features, both for interactive use and programming. If you are new to shell programming, Learning the bash Shell provides an excellent introduction, covering everything from the most basic to the most advanced features, like signal handling and command line processing. If you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. The book is full of examples of shell commands and programs that are designed to be useful in your everyday life as a user, not just to illustrate the feature being explained. All of these examples are freely available to you online on the Internet. This second edition covers all of the features of bash Version 2.0, while still applying to bash Version 1.x. New features include the addition of one-dimensional arrays, parameter expansion, and more pattern-matching operations. bash 2.0 provides even more conformity with POSIX.2 standards, and in POSIX.2 mode is completely POSIX.2 conformant. This second edition covers several new commands, security improvements, additions to ReadLine, improved configuration and installation, and an additional programming aid, the bash shell debugger. With this book you'll learn: How to install bash as your login shell The basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobs Command line editing, history substitution, and key bindings How to customize your shell environment witho...

    Abstract: sed & awk describes two text processing programs that are mainstays of the UNIX programmer's toolbox. sed is a "stream editor" for editing streams of text that might be too large to edit as a single file, or that might be generated on the fly as part of a larger data processing step. The most common operation done with sed is substitution, replacing one block of text with another. awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts.This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk , where POSIX standardized a new variable, CONVFMT, and new functions, toupper () and tolower (). The CONVFMT variable specifies the conversion format to use when converting numbers to strings ( awk used to use OFMT for this purpose). The toupper () and tolower () functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case.In addition, this edition covers GNU sed , newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk ( gawk ), covers mawk , an additional freely available implementation of awk , and briefly discusses three commercial versions of awk , MKS awk , Thompson Automation awk ( tawk ), and Videosoft (VSAwk).

    Abstract: Steven Feuerstein's first book, Oracle PL/SQL Programming , has become the classic reference to PL/SQL, Oracle's procedural extension to its SQL language. His new book looks thoroughly at one especially advanced and powerful part of the PL/SQL language -- the package. The use of packages can dramatically improve your programming productivity and code quality, while preparing you for object-oriented development in Oracle technology. In this book, Feuerstein explains how to construct packages -- and how to build them the right way. His "best practices" for building packages will transform the way you write packages and help you get the most out of the powerful, but often poorly understood, PL/SQL language. Much more than a book, Advanced Oracle PL/SQL Programming with Packages comes with a PC diskette containing a full-use software companion. Developed by Feuerstein, RevealNet's PL/Vision Lite is the first of its kind for PL/SQL developers: a library of thirty-plus PL/SQL packages. The packages solve a myriad of common programming problems and vastly accelerate the development of modular and maintainable applications. The packages provided in PL/Vision Lite fall into three categories: Building block packages: low-level development enhancers, including string parsers, a list manager, and an interface to PL/SQL tables. Developer utilities: programs that improve your PL/SQL development environment, including a code generator, a powerful substitute for SHOW ERRORS, and an online help delivery mechanism. Plug-and-play components: pieces of code that can be used as is in your own applications, including a high-level exception handler mechanism and a generic, reusable logging mechanism. In addition to describing the details of these packages, this book explores why and how they were built the way they were. You'll come away with an increased appreciation of the PL/SQL language and the power of packages. Most importantly, you'll be ready and eager to put that power to use immediately in your own applications.

    Abstract: If you use UNIX, you know that it can be a technically challenging environment. And if you're like most users, you have a job to do aside from exploring your operating system -- like analyzing that hot new stock, running another experiment, or typesetting another report. What happens when you have problems? What happens when the system slows to a crawl, when you can't get logged back in after a power failure, or when you've sent a file to the printer three times but have yet to find a printout? Your first choice for handling a problem might be to have the problem never occur. Your second choice might be to have someone else fix it, immediately. However, in the real world, sometimes you will have to investigate the problem and report it, and sometimes you will have to find an answer yourself. When You Can't Find Your UNIX System Administrator , part of our new What You Need to Know series, gives UNIX users tools for solving problems. It offers: Practical solutions for problems you're likely to encounter in logging in, running programs, sharing files, managing space resources, printing, and so on Just enough background on what's going on "behind the scenes" so that you can make sense of our suggestions, rather than simply memorizing keystrokes An explanation of how to present problems to your sys admin so that you're more likely to get quick, accurate support A list of the site-specific information to which you should have access, and a place to write it down A quick-ref card summarizing what to try first, second, third for commonly encountered problems The goal of this book is not to make you a guru in your own right. The goal of this book is to get you back to the job you'd rather be doing.

    Abstract: This Nutshell Handbook(R) is a thorough introduction to the Korn shell, both as a user interface and as a programming language.The Korn shell, like the C and Bourne shells, is a program that interprets UNIX commands. It has many features that aren't found in other shells, including command history (the ability to recall and edit previous commands). The Korn shell is also faster; several of its features allow you to write programs that execute more quickly than their Bourne or C shell equivalents.This book provides a clear and concise explanation of the Korn shell's features. It explains ksh string operations, co-processes, signals and signal handling, and one of the worst "dark corners" of shell programming: command-line interpretation. It does this by introducing simple real-life examples and then adding options and complexity in later chapters, illustrating the way real-world script development generally proceeds. An additional (and unique) programming aid, a Korn shell debugger ( kshdb ), is also included. Learning the Korn Shell is an ideal resource for many UNIX users and programmers, including software developers who want to "prototype" their designs, system administrators who want to write tools for their own use, and even novices who just want to use some of ksh's more advanced interactive features.
