Perl is a very powerful tool for Oracle database administrators, but too few DBAs realize how helpful Perl can be in managing, monitoring, and tuning Oracle databases. Whether you're responsible for Oracle9i, Oracle8i, or earlier databases, you'll find Perl an invaluable addition to your database administration arsenal.You don't need to be a Perl expert to use the excellent applications and scripts described in Perl for Oracle DBAs. The book explains what you need to know about Perl, provides a wealth of ready-to-use scripts developed especially for Oracle DBAs, and suggests many resources for further exploration. The book covers:The Perl language -- an introduction to Perl, its rich history and culture, and its extensive text processing and data transformation capabilities.The Perl/Oracle architecture -- Detailed information about Perl DBI, DBD::Oracle, the Oracle Call Interface (OCI), Oracle::OCI, extproc_perl, and mod_perl, the modules that allow Perl programs to communicate with Or acle databases.Perl applications for Oracle DBAs -- Profiles of the best Perl open source applications available for use and customization by Oracle DBAs: Perl/Tk, OraExplain, StatsView, Orac, DDL::Oracle, SchemaDiff, Senora, DBD::Chart, SchemaView-Plus, Oracletool, Karma, Embperl, and Mason.The Perl Database Administration (PDBA) Toolkit -- a comprehensive suite of specialized, ready-to-use scripts designed to help Oracle DBAs perform both routine and special-purpose administrative tasks: monit oring the Oracle alert log and databases, creating and managing Oracle user accounts, maintaining indexes and extents, extracting DDL and data, troubleshooting and tuning database problems, and much more.The book also explains how Oracle DBAs and developers can extend the toolkit and solve their own database administration problems using Perl.

Oracle & Open Source is the first book to tie together the commercial world of Oracle and the free-wheeling world of open source software. As this book reveals, these two worlds are not as far apart as they may seem. Today, there are many excellent and freely available software tools that Oracle developers and database administrators can use, at no cost, to improve their own coding productivity and their system's performance. Moreover, many of the finest Oracle developers are now making thei r source code freely available so their peers can build upon this code base. Oracle Corporation is even porting its RDBMS to Linux and starting to incorporate a growing number of open source tools in the company's own software. Oracle & Open Source describes close to 100 open source tools you can use for Oracle development and database administration, from large and widely known open source systems (like Linux, Perl, Apache, TCL/Tk and Python) to more Oracle-specific tools (like Orasoft, Ora c, OracleTool, and OraSnap). You'll learn how to obtain the software and how to adapt it to best advantage. The book abounds with code examples, download and installation instructions, and helpful usage hints. Not only does it tell you how to find and use existing open source code; Oracle & Open Source gives you the details and the motivation to build your own open source contributions and release them to the Oracle community. You'll lear n all about tools like the Oracle Call Interface (OCI) and Perl-DBI (Database Interface), which provide the glue allowing new open source tools to link into commercial Oracle software. With Oracle & Open Source as a guide, you'll discover an enormous number of highly effective open source tools, while getting involved with the thriving community of open source development.

Perl is a powerful programming language that has grown in popularity since it first appeared in 1988. The first edition of this book, Programming Perl, hit the shelves in 1990, and was quickly adopted as the undisputed bible of the language. Since then, Perl has grown with the times, and so has this book. Programming Perl is not just a book about Perl. It is also a unique introduction to the language and its culture, as you might expect only from its authors. Larry Wall is the inventor of Perl, and provides a unique perspective on the evolution of Perl and its future direction. Tom Christiansen was one of the first champions of the language, and lives and breathes the complexities of Perl internals as few other mortals do. Jon Orwant is the editor of The Perl Journal, which has brought together the Perl community as a common forum for new developments in Perl.

Explains how to use the common gateway interface (CGI) to create and deliver dynamic content on the web. The second edition has been rewritten to demonstrate current techniques available with the CGI.pm module and the latest versions of Perl. 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 c alling external programs to crunch numbers, query databases, generate customized graphics, or performing any other server-side task.

"The DBI is a database interface module for Perl. It defines a set of methods, variables and conventions that provide a consistent database interface independent of the actual database being used", explains Bunce, the architect and inventor of DBI. He and Descartes, one of the most active members of the DBI community, explain the architecture of DBI and show how to write DBI-based programs. For the DBI expert, they cover the nuances and peculiarities of each individual database driver. The basic s of databases are well-covered, but some experience programming with Perl is assumed. One of the greatest strengths of the Perl programming language is its ability to manipulate large amounts of data. Database programming is therefore a natural fit for Perl, not only for business applications but also for CGI-based Web and Intranet applications.

From access counters and log-report graphs to scientific plots and on-the-fly animated GIFs, graphics scripting is within the grasp of most Web authors. However, it is a poorly documented field. Programming Web Graphics with Perl & GNU Software shows intermediate and advanced Web designers how to use CGI scripts to generate dynamic graphic content and demystifies the manipulation of graphics formats for newcomers to the Web. "Programming Web Graphics with Perl and GNU Software" shows interme diate and advanced Web designers how to use CGI scripts to generate dynamic graphic content and demystifies the manipulation of graphics formats for newcomers to the Web.
