ACKNOWLEDGMENTS

I

wish to acknowledge the excellent technical editing of the book by April Wells. Thanks to
April’s careful and expert technical vetting, I’ve been able to avoid errors and improve the
quality of the presentation.
In the last few years, over the course of writing three books for Oracle Press,
Timothy Green, Senior Acquisitions Editor, has also become my friend. Tim’s
sagacious replies to queries as well as excellent counsel and encouragement have
been extremely helpful. I also thank the excellent help and support provided by

the Acquisitions Coordinator, Jennifer Housh.
I appreciate the terrific job done by Laura Stone, the Project Editor, in seeing the
chapters through all the editing and production stages with great patience, skill, and
cheer. Laura has shown great alacrity and exceptional understanding at various stages
of the manuscript to keep the workflow moving steadily. Exceptional copy editing by
Nancy Rapoport has significantly enhanced the style and presentation of the contents
of the book. I’m also grateful to the great proofreading by Susie Elkind. I’m lucky to
have friends at work such as Myra Riggs and Dabir Haider. Myra always finds time to
talk about just about anything, and I can always count on her help and advice. Dabir
has been a source of help and support ever since he joined us last year. I couldn’t have
taken care of business without the kind help of Leticia Salazar, who has gone out of
her way to help me in numerous ways throughout the last year—thanks, Leticia! My
buddy Mark Potts has been a true friend over the years and I’m grateful to him for all
his help. My colleagues at work, Lance Parkes and Rob Page, are always helpful, and I
acknowledge their kindness as well. I’m fortunate to work with David Jeffress and Dave
Campbell, two exceptional managers, and thanks go out to both of them. I would also
like to express my appreciation for Dan Nelson and Debra Kendrew for their friendship
and caring.
Finally, I’d like to extend my profound thanks to both of my families. I’m grateful to
Mom; Dad; and my two brothers, Hari Hara Prasad and Siva Sankara Prasad; for their
love, affection, and support. Thanks also to Aruna, Vanaja, Ashwin, Teja, Aparna,
and Soumya for their love and kindness over the years. I wish to acknowledge the
enormous debt I owe to my wife, Valerie, who had to fill in the void left by my absence
from the home front during the writing of this book. Finally, thanks to Shannon and
the twins, Nina and Nicholas, who always love it when we get to look at the first
copies of a newly printed book!

INTRODUCTION

O

racle Database 11g offers several highly powerful enhancements to the management
of Oracle databases. Oracle databases are the leading commercial databases in the
world today, and it’s a great challenge as well as a matter of pride to certify in the latest
flagship offering of the Oracle Corporation. For more information about the Oracle certification
exams, requirements for certification, or recertification, please visit Oracle’s certification web site
( />This book will help you in your endeavor to upgrade your Oracle OCP DBA
certification to the latest level—Oracle Database 11g. It is a study guide for Oracle
Database administrators who plan to take the OCP Oracle Database 10g: New Features
for Administrators Exam Guide (Exam 1Z0-050). This exam is also known commonly
as the DBA “Upgrade” exam because you can upgrade to the latest Oracle Database 11g
OCP certification from the Oracle10g OCP certification. In order to take this exam,
Oracle Corporation must have already certified you as an Oracle10g OCP.
If your goal is to update your credentials, you can do so by diligently working through
this book, doing all the exercises and practice tests. However, your goal should ideally
reach beyond passing the exam. Ultimately, you’ll need to use the new skills you learn
in your present job, and the only way to do so is by clearly understanding the nuances of
the various enhancements offered by the Oracle Database 11g release. To this end, I’ve
designed this book as much more than a simple exam guide, by carefully introducing the
topics and discussing them in sufficient detail to provide you with a solid understanding.
Some of you, I’m sure, are tempted to just learn the minimum necessary to pass the
upgrade exam. However, I urge you to delve deeper into the new release by testing
the new features on your own and exploring the many new capabilities of the Oracle
Database 11g release. In general, Oracle certifications are voluntary, in the sense that
in most cases they are not prerequisites for a job working with Oracle products. The
real value of certification comes in the mastery of a wide range of capabilities of the
Oracle database software. As the first chapter shows you, it is easier to install the new

Oracle software than ever before. Therefore, you really don’t have any excuses for not
installing the Oracle Database 11g software on your workstation or a test server and
exploring all the new features. I’ve found that testing the various features is the best
way to understand and remember the nuances of the new features, including the usage
of the new commands and SQL statements that help implement the features.

In This Book
This book is organized to serve as an in-depth review for the OCP Oracle Database
11g: New Features for Administrators Exam for Oracle professionals who already are
certified OCPs. Each chapter covers a major aspect of the exam; all the OCP official
certification objectives are carefully covered in the book.

Introduction

On the CD-ROM
The CD-ROM contains the entire contents of the book in electronic form, as well as
two practice tests that simulate the real Oracle Database 11g OCP certification test.
For more information on the CD-ROM, please see the appendix.

Exam Readiness Checklist
At the end of this introduction, you will find an Exam Readiness Checklist. I
constructed this table to allow you to cross-reference the official exam objectives with
the certification objectives as I present and cover them in this book. The checklist
also allows you to gauge your level of expertise on each objective at the outset of your
studies. This should allow you to check your progress and make sure you spend the

time you need on more difficult or unfamiliar sections. I’ve provided a reference for
each objective exactly as Oracle Corporation presents it, including the section of the
study guide that covers that objective, as well as a chapter and page reference.

In Every Chapter
This book includes a set of chapter components that call your attention to important
items, reinforce important points, and provide helpful exam-taking hints. Take a
look at what you’ll find in every chapter:
■ Exam Watch notes call attention to information about, and potential pitfalls

in, the exam. As I mentioned earlier, I took the new OCP exam and received
my certification. I took the Beta exam in December, 2008—it had over 170
questions, so I know something about what you will go through!
■ Exercises are interspersed throughout the chapters, and they allow you to

get the hands-on experience you need in order to pass the exams. They help
you master skills that are likely to be an area of focus on the exam. Don’t
just read through the exercises; they are hands-on practice that you should
be comfortable completing. Learning by doing is an effective way to increase
your competency with a product.
■ On the Job notes describe the issues that come up most often in real-world

settings. They provide a valuable perspective on certification- and productrelated topics. They point out common mistakes and address questions that
have arisen from on-the-job discussions and experience.
■ Inside the Exam sections toward the end of each chapter are designed to

anticipate what the exam will emphasize. I provide pointers regarding key
topics to focus on, based on my own exam experience. You can get a leg up

OCP Oracle Database 11g: New Features for Administrators Exam Guide

on how to respond to actual exam questions by focusing extra attention on
the contents referred to in the Inside the Exam sections.
■ The Certification Summary is a succinct review of the chapter and a

✓
Q&A

restatement of salient points regarding the exam.
■ The Two-Minute Drill at the end of every chapter is a checklist of the main

points of the chapter. You can use it for a quick, last-minute review before
the test.
■ The Self Test offers questions similar to those found on the certification

exam. The answers to these questions, as well as explanations of the answers,
can be found at the end of each chapter. By taking the Self Test after
completing each chapter, you’ll reinforce what you’ve learned from that
chapter, while becoming familiar with the structure of the exam questions.
■ The Lab Questions at the end of the Self Test sections offer a unique and

challenging question format that, in order to answer correctly, require the
reader to understand multiple chapter concepts. These questions are more
complex and more comprehensive than the other questions, as they test your
ability to take all the knowledge you have gained from reading the chapter
and apply it to complicated, real-world situations.

Some Pointers
Once you’ve finished reading this book, set aside some time to do a thorough review.
You might want to return to the book several times and make use of all the methods
it offers for reviewing the material:
■ Reread all the Two-Minute Drills or have someone quiz you. You also can

use the drills as a way to do a quick cram before the exam. You might want
to make some flash cards out of 3 × 5 index cards that have the Two-Minute
Drill material on them.
■ Reread all the Exam Watch notes. Remember that these notes are based on

the OCP exam that I took and passed. I’ve tried to draw your attention to
what you should expect—and what you should be on the lookout for.
■ Retake the Self Tests. It is a good idea to take the test right after you’ve read

the chapter because the questions help reinforce what you’ve just learned.
However, it’s an even better idea to go back later and do all the questions
in the book in one sitting. Pretend that you’re taking the live exam. (When
you go through the questions the first time, you should mark your answers
on a separate piece of paper. That way, you can run through the questions
as many times as you need to until you feel comfortable with the material.)
