• Identify the Tool for Administratering an Oracle Database(识别Oracle数据库管理工具)
• Plan an Oracle Database Installation(准备Oracle数据库安装)
• Install the Oracle Software by Using the Oracle Universal Installer(OUI)(使用OUI安装Oracle软件)

A number of tools are available for managing an Oracle database,beginning with the Oracle Universal Installer(the OUI).This is an Oracle product in its own right that is used to manage the installation and maintenance of many other products.(可以获得的Oracle数据库管理工具有很多，让我们从OUI开始。这是一个具有Oracle版权的产品，常被用来管理Oracle的安装和其他产品的维护。)The installation of Oracle software has,as fas as possible,been standardized for all products on all platforms-but there are platform and product variations.(Oracle软件的安装尽可能地做到不同平台上的所有产品标准化，但是，平台和产品是由许多版本的。)Before isntalling anthing,it is essential to read the product's release notes for the platform concerned.(在安装之前，有必要阅读一下产品的有关本平台的发布说明。)This chapter goes through the process of planning the installation and then installing the Oracle Database 11g software width examples from Linux and Widnows.(本章主要涉及到安装的准备过程和在Linux和Windows上安装带例子的11g数据库。)

Indentify the Tools for Administering an Oracle Database

Oracle Corporation provides a number of tools for managing the Oracle environment.First(and the main subject of this chapter) there is the OUI,the Oracle Universal Installer.Second,there are tools for creating and upgrading a database.These can be launched from the OUI or run separately(as is done in Chapter 4).Third,the OUI will install a number of other tools for managing a database and related components,notably SQL*Plus.Depending on the installation type chosen,it may install SQL Developer,but iSQL*Plus,a product strongly advocated with database releases 9i and 10g,is no longer supplied.

(Oralce公司提供了许多管理Oracle环境的工具。首先（也是本章的主题）是OUI。其次是创建和升级数据库的工具，可以从OUI中启动或单独运行（在第四章中有描述）。第三，OUI会安装许多管理数据库的其他工具和相关组件，例如常见的SQL*Plus。依据选择的安装类型，可能会安装SQL Developer，但是将不再支持9i和10g强烈主张的产品iSQL*Plus。)

Oracle Enterprise Manager needs a special mention.It comes in several forms,one of which(the Oracle Enterprise Manager Database Control) will be used extensively in this book.

(需要特别注意一下Oracle 企业管理器，它的展现方式多种多样，在本书中广泛运用的是OEMDC)。

The Oracle Universal Installer

Historically,managing Oracle softeware could be a painful task.This was because the DBA was largely responsible for ensuring that incompatible products were kept separate.It was not uncommon to install one product,a second,and a third satisfactorily-then installation of a fourth would break the other three.The problem of incompatibilities lies in the use of the base libraries.The base libraries provide facilities that are common to all Oracle products.For example,all Oracle products use the Oracle Net communications protocal;it is impossible to install a product without it.If two products are built on the same version of the base libraries,then(theoretically) they can coexist in the same Oracle Home.An Oracle Home is the location of an Oracle product isntallation:a set of files in a directory structure.Bef
