Preface

Oracle Corporation has become one of the largest software companies in the world

with its premier Relational Database Management System known as Oracle. Larry

Ellison, the current CEO, founded the company back in the 1970s. The growth

of technology over the last twenty years also fueled the implementation of large

databases to maintain control of the explosive growth of data. Through many

technical advances and superior design, Oracle rose to the top when companies

were choosing the database technology for their enterprise systems.

The role of the Database Administrator (DBA) includes certain key

responsibilities—disaster recovery, database architecture and design, as well

as performance tuning. Specic tasks also include new installations, security

administration, and proactively monitoring all systems at several levels. Because of

the great responsibility associated with being a DBA, a concerted effort is required

to integrate a constant stream of new knowledge within a locally customized

environment. While the documentation and training classes provide some

benet for the basics, it is the advice that comes from experience that lays the

real foundation for a career.

DBAs must work closely with other IT members to maintain a high level of

dependability for enterprise applications that run on Oracle, often outlined in an

ofcial Service Level Agreement. That is what this book is all about—integrating

old knowledge with new ideas, while interacting with all levels of expertise within

the Oracle Enterprise.

Preface

[ 2 ]

What this book covers

Chapter 1, When to Step Away from the Keyboard, answers the question "What does

a DBA do all day?" It contains a comprehensive list of prioritized tasks that the

average DBA is responsible for. A common theme throughout the book is introduced

in this chapter: Tools should be extensible, exible, and ubiquitous. Included in this

chapter is a list of commonly seen mistakes that can be easily avoided by adopting

recommended practices. Emphasis is placed on the attitude and philosophy that a

DBA should have while doing their job as a valuable team member.

Chapter 2, Maintaining Oracle Standards, discusses "standards" such as Oracle's

Optimal Flexible Architecture, Unix shell scripting, code and conguration basics.

This is meant to provide a solid foundation designed to reduce future maintenance.

This is where your dedication to detail comes into play, as it takes work to enforce

standards, especially when the personnel in your department change. A DBA

should be comfortable with the fact that a migration to the next patch set, version,

or hardware replacement will always be in progress. This requires multiple Oracle

Homes with completely separate environments that can be easily switched; this

chapter outlines how to accomplish this goal. The new 11g Automatic Diagnostic

Repository features, for diagnosing and repairing certain types of failures, will be

outlined in the chapter as well.

Chapter 3, Tracking the Bits and Bytes, covers how data moves from one database

component to the next; the mechanics or essential architectural infrastructure at

the block level; what the data in a datale, redo, undo, or archivelog actually looks

like; and how the database keeps up with SCN changes. Dumping database blocks

provides the raw hexadecimal values that convert to the characters that the end

user sees at the application level. Other utilities such as LogMiner can be used to

access information from certain database components, as well as the very basic Unix

command strings. These essential concepts will provide you with the condence that

you can survive any disaster that you may have to tackle. Corruption prevention and

detection is covered because this is one of the real tests for excelling at your job. No

one really wants to have to x corruption when it happens, because the data

becomes unrecoverable fast.

Chapter 4, Achieving Maximum Uptime, covers redundancy at all levels: hardware,

software, databases, ASM, SAN(s), and load balancers. Databases become

redundant with Data Guard and RAC. This chapter offers an introduction to

network and SQL*Net tuning for all types of implementations. Achieve the smallest

outage windows by moving to rolling upgrades, ensuring there is some sort of

backup plan for important personnel as well as documenting congurations with

Oracle Conguration Manager. There are always single points of failure in every

organization; identifying them is the rst step on the path to a fully documented

disaster recovery plan.

Preface

[ 3 ]

Chapter 5, Data Guard and Flashback, explains that the combination of Oracle's

Flashback and Data Guard makes recovery scenarios, stress testing, and hot x

patching on a physical standby possible by making the database read and write

temporarily. Using both Data Guard and Flashback in tandem can reduce or

eliminate downtime for the primary database in certain types of recovery situations.

It may reduce or eliminate the need for duplication of hardware for testing

purposes. Several scenarios are outlined in detail, along with recommendations

for implementations that fulll disaster recovery goals.

Chapter 6, Extended RMAN, covers the essential tool for DBAs—RMAN, which is just

complicated enough to warrant its own chapter. In this chapter, we will provide the

foundations for writing your own scripts to get you started using this utility today.

While the previous standard backups consisted of either a basic cold or hot version,

RMAN does that and also adds even more exibility when automating backup (and

even recovery) routines. RMAN is the basic utility behind several types of disaster

recovery and migration tasks such as: Creating Physical and Logical Standby(s).

You can restore between different versions and migrate to new hardware using

Transportable Tablespaces. RMAN is also involved with 11g's ADR Detected

Failure Repairs, as well as duplication across the network (both local and remote).

Chapter 7, Migrating to 11g: A Step-Ordered Approach

, talks about how migrating to a

newer Oracle Database version doesn't have to be conned to a single outage period.

Several interim steps can be done ahead of time to certain compatible components,

saving valuable time. In a general sense, Oracle is backwards compatible for making

that transition from an earlier version to a later one. The following components can

be upgraded while still remaining compatible with earlier versions of Oracle:

• Oracle Net Services

• Clients

• RMAN binary, Virtual Private, and Normal Catalog Database

• Grid Control Repository Database

• Grid Control Management Agents

• Automatic Storage Management and Clusterware

This is an essential guide for upgrading to 11g using a multiple home environment:

Cloning Oracle homes, Oracle Universal Installer (interactive, silent, and suppressed

modes), RMAN catalog, and SQL Net. All of the options for performing upgrades are

touched on in this book: DBUA, Manual Method, Export/Import, Data pump, TTS,

RMAN, Physical Standbys, and the newer Transient Logical Standby.

Preface

[ 4 ]

Chapter 8, 11g Tuning Tools, covers ORION, TRCANL�R, and Statspack utilities. TRCANL�R, and Statspack utilities. and Statspack utilities.

While it is easy to show someone how to use a tool, it takes experience to correctly

interpret the results you get. This chapter will also cover different free-source,

load-testing tools for forecasting trends of CPU utilization and I/O; in other words

predicting the approximate time to purchase new hardware before the end user

experiences degraded performance. 11g features such as SQL Plan Management

will be covered along with Oracle's own Enterprise Manager tuning tools. A large

portion of this chapter is dedicated to the migration path for upgrading the query

optimizer using SQL Plan Management from 10g to 11g. Start a new paragraph from

here, you might still be overwhelmed with all of the work set before you, and that's

is why you've bought this book in the rst place. This is a book you will keep for a

long time, referring back again and again for each new project. It will be especially

handy to show management when they start altering your job description. It is our

hope that this is only a starting place for your career as a DBA and that by reading

this book, you will share the knowledge with your peers as an active participant in

Oracle User Groups.

What you need for this book

It would be helpful if you have some knowledge of SQL and are comfortable with

the Unix operating system, but this is not absolutely essential. For those new to these

technologies, keep the documentation nearby to use as a reference. This book is

written for the Unix operating system, but you may only have access to a Windows

operating system such as a desktop for testing purposes. There are tools, such

as Cygwin (for Windows), which enable many of the same operating system

commands to work on both Unix and Windows.

This book focuses on 11g Release 2 version with a reference to general Unix operating

system commands. Previous versions of Oracle are also referenced when it applies to

migration or upgrading to 11g as the topic. The Oracle Database Installation Guide for

the version you are installing will have the prerequisite hardware requirements. The

best place to start for the latest documentation and Oracle software downloads is the

Oracle Technology Network (OTN) website:

http://otn.oracle.com.

Who this book is for

This is for you if you nd yourself in charge of an Oracle Database (understanding

the full responsibility that goes with such a position), but are unsure of what

tasks you need to perform. It can be easy to feel overwhelmed, so this reference is

designed as a sanity check, whether you are a single employee or the DBA manager

of several employees, or whether you are taking over an existing position or taking

up a newly created one.
