Using Oracle8


Introduction

Welcome to Using Oracle8! This book identifies the many functions an Oracle DBA needs to perform on an Oracle8 database and explains how to do them as efficiently and effectively as possible. You learn about the key functions of database administration, including installing the product, designing and creating a database and its tablespaces, designing and creating the tables and other objects that make up an Oracle database, designing and executing a good backup strategy with a recovery methodology, and monitoring and tuning performance. You also learn about creating and maintaining users and performing an upgrade to Oracle8, as well as other tasks that you may need in your position as DBA. You also learn when and how to use the various tools Oracle8 provides to assist you in database management, performance monitoring and tuning, data loading, backup and recovery, and data export and import.

The book is designed to let you read about a topic at length when you have the time and the inclination, or to use as a quick reference guide when you need an answer to a pressing technical question or an example to follow when performing a specific task.

Using Oracle8 contains cross-references to related topics so that you can look at all aspects of a topic, even if they're covered in different chapters. These cross-references also enable you to read the book in any order you choose. If you run across a subject you don't fully understand, you can easily switch your attention to the area(s) identified and carry on your reading there. Where applicable, the book also references the Oracle documentation materials, so you can find even more detail if you need it.

Don't forget to keep this book handy at work, just in case you need to check something in a hurry that you haven't read about yet or is a new topic to you. Be sure also to use the tear-out card inside the book's cover. It contains some of the most common, but difficult to remember, information you'll need.

Who Should Use This Book

You'll get the most out of this book if you have some background in the SQL language and some knowledge or experience with relational databases. Because Oracle's SQL language is based on the ANSI standard, it's not discussed in detail in this book, but numerous examples use SQL statements. The theory of relational databases is also outside the scope of this book, as are the internal structures within Oracle, except where they're needed to help you understand how or why to perform a specific task.

This book is intended primarily for DBAs who have some knowledge of relational databases. Much of this book will be familiar if you've worked with earlier releases of Oracle-but you'll find the new Oracle8 features discussed. If you've worked with other relational databases, you may need to refer to the glossary if you find brand new terms or terms that have different meanings in Oracle. If you haven't worked with any relational databases, you should expect to follow the frequent cross-references to sections of the book; this will fill in background information as you read about a topic.

Acknowledgments

From David Austin:

Thanks to the many professionals who have helped and encouraged me in my career and my work on this book, particularly my various managers, instructors, and colleagues at Oracle, including Deborah West, Chris Pirie, Nick Evans, Vijay Venkatachalam, Larry Mix, Beth Winslow, Sue Jang, Scott Gossett, and Scott Heisey. I would also like to say thank you to some of my earliest mentors in this business-Bob Klein, Donald Miklich, and Roland Sweet, wherever they might be.
Thanks also to the various editors at Que who helped shepherd this work from its inception to the book you now have in your hands, with a special mention for Angela Kozlowski and Susan Dunn. I also want to thank my coauthors, without whose efforts this work could never have been finished.
Finally, a thank you to my family for putting up with the long hours I spent ignoring them while working on this project. My wife, Lillian, is now bracing for the revisions, while my kitten is just happy that she once again gets some petting when she sits in my lap.

From Vijay Lunawat:

Most thanks go to my two children, Siddharth and Sanchi, and my wife, Sushma, for their patience and for putting up with my long and weekend working hours while I was writing for this book.

From Meghraj Thakkar:

I would like to give a special thanks to my wife, Komal, for her patience and understanding.

From Raman Batra:

To my lovely wife, Sarika, for her understanding and admirable patience in keeping my daughter, Nikita, away from me, when I was writing. Nikita had a real hard time understanding why Daddy was working with such "boring" text stuff with no music, when she could be watching her Winnie the Pooh CD on Daddy's PC.

From Joe Duer:

I would like to thank once again the Tuesday night crew at Shelton EMS: Jason, Betty, John, and Denise. Your help covering all the shifts I missed because I was writing is greatly appreciated.
I would like to thank everyone at Que-in particular, Angela Kozlowski and Susan Dunn-for their help and guidance during the development of this book.
