    Andy Duncan is the coauthor of Oracle & Open Source (O'Reilly, 2001), as well as Perl for Oracle DBAs (O'Reilly, 2002). The first book arose after Andy's creation, in 1998, of the Orac Perl/Tk tool for Oracle DBAs. Since then, he has worked mainly as an independent development and DBA consultant, and has counted both Oracle Corporation and Sun Microsystems among his long-term clients. In addition to performing Oracle, Perl, and Java consultancy work, Andy teaches as a senior instructor for Learning Tree International, covering both introductory and advanced Perl courses. He lives in Oxfordshire, England.

    Jared Still has been an Oracle DBA in health insurance and manufacturing environments since 1994 (and version 7.0.13 of Oracle). He first began dabbling with Perl in 1993 and it was love at first sight. Perl became an integral part of his Oracle toolkit when it was used to rapidly prototype and implement complex reporting based on data in Oracle databases. Jared has been working with databases of various ilks since 1988, and along the way has also worked as a Unix system administrator. When not riding herd on the databases at the OK Corral, he likes to spend time tinkering on his car, fly fishing, or sitting on the deck in the backyard at his home doing absolutely nothing. He can be reached at jkstill@cybcon.com.

    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 Oracle 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: monitoring 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.
