  3. Completing preinstallation tasks: Chapter 2 describes preinstallation tasks that you must complete before installing the product.

  4. Installing software: Use the following section to install Oracle Database:

    • Chapter 3 describes how to use Oracle Universal Installer to install Oracle Database.

    • Appendix A provides information on performing noninteractive (silent) installations, which you may want to use if you must perform multiple installations of Oracle Database.

    • Appendix B provides information on cloning Oracle home.

    • Appendix E describes globalization support information.

    • Appendix F provides troubleshooting advice in case you encounter problems with the installation.

    • Chapter 6 describes how to remove Oracle Database.

  5. Completing postinstallation tasks: Chapter 4 describes recommended and required postinstallation tasks.

  6. Get started using Oracle Database: Chapter 5 describes how to check the contents of the installed Oracle Database, how to start various tools, and how to locate various files. Appendix C describes the Optimal Flexible Architecture, which is a set of guidelines that ensure reliable Oracle installations that require little maintenance, and Appendix D explains how to manage Oracle Database port numbers.

Oracle Database Installation Methods

You can choose different installation methods to install Oracle Database, as follows:

Interactive Installation Methods

When you use the interactive method to install Oracle Database, Oracle Universal Installer displays a series of screens that enable you to specify all of the required information to install the Oracle Database software and optionally create a database.

With Oracle Database 10g release 10.2 on Apple Mac OS X (Intel), Oracle Universal Installer provides two interactive methods that you can use to install Oracle Database:

  • Basic Installation method:

    Select this installation method to quickly install Oracle Database. This installation method requires minimal user input. It installs the software and optionally creates a general-purpose database using the information that you specify on the screen. It is the default installation method.

  • Advanced Installation method:

    Select this installation method to complete any of the following tasks:

    • Perform a custom software installation, or choose a different database configuration

      The Available Product Components installation screen automatically selects the components most customers need in their Oracle Database installation. It also lists several components that are not selected by default, but which you may want to include. To find the listing of available components, select Advanced, and then in the Installation Type screen, select Custom.

    • Select a database character set or different product languages

    • Create the EXAMPLE tablespace during the installation

    • Create a database on a different file system from the software

    • Specify different passwords for administrative schemas

    • Configure automated backups

Automated Installation Methods Using Response Files

By creating a response file and specifying this file when you start Oracle Universal Installer, you can automate some or all of the Oracle Database installation. These automated installation methods are useful if you must perform multiple installations on similarly configured systems or if the system where you want to install the software does not support a graphic user interface.

When you use a response file, you can run Oracle Universal Installer in the following modes, depending on whether you specify all of the required information or not:

  • Silent Mode: Oracle Universal Installer runs in silent mode if you use a response file that specifies all required information. None of the Oracle Universal Installer screens are displayed.

  • Suppressed Mode: Oracle Universal Installer runs in suppressed mode if you do not specify all required information in the response file. Oracle Universal Installer displays only the screens that prompt for the information that you did not specify.

For more information about these modes and about how to complete an installation using response files, refer to Appendix A.

Oracle Database Installation Types


Oracle Database Client is installed separately. You cannot install Oracle Database Client during an Oracle Database installation.

You can choose an installation type from the following list, when installing Oracle Database 10g:


For more information about the features available with each Oracle Database edition and for information about licensing, refer to the Oracle Database Licensing Information guide.

  • Enterprise Edition: Installs licensable Oracle Database options and database configuration and management tools in addition to all of the products that are installed during a Standard Edition installation. It also installs products most commonly used for data warehousing and transaction processing.

  • Standard Edition: Installs an integrated set of management tools, full distribution, replication, Web features, and facilities for building business-critical applications.


    If you perform a Custom installation, then ensure that you install only the components covered by your license. You cannot install Standard Edition using Custom installation.
  • Custom: Enables you to select the individual components that you want to install from the list of all available components.

Database Configuration Options

During the installation, you can choose whether you want to create an Oracle database as part of the installation. If you choose to create an Oracle database, then Oracle Universal Installer uses Database Configuration Assistant to create it. You can choose to create a preconfigured database type, which is designed for a variety of different applications, or modify a preconfigured database type, or create a customized database to suit your requirements.

This section describes the following database configuration options:

Preconfigured Database Types

Oracle provides the following preconfigured database types that you can create or customize during the installation:

  • General Purpose

  • Transaction Processing

  • Data Warehouse

Refer to the online help provided by either Oracle Universal Installer or Database Configuration Assistant for a description of these preconfigured database types.

Installation Choices that Affect Database Creation

Oracle Universal Installer runs Database Configuration Assistant in one of two modes, depending on the choices that you make during the installation:

  • Noninteractive mode

    If you choose either the Enterprise Edition or Standard Edition installation type, then choose to create a preconfigured database type. Oracle Universal Installer prompts you for the minimum amount of information required to create a database of the type you choose. It then runs Database Configuration Assistant in noninteractive mode to create the database after it installs the software.

  • Interactive mode

    If you choose the Custom installation type or choose the Advanced database configuration option, then Oracle Universal Installer does not prompt you for database information. Instead, it installs the software and then runs Database Configuration Assistant in interactive mode. Using the screens in Database Configuration Assistant, you can either modify a preconfigured database type or create a custom database and specify precisely how you want to configure it.


    If you choose this method to create a database, then click Help on any of the Database Configuration Assistant screens for a description of the information that you must specify on that screen.

Creating a Database After Installation

If you decide not to create a database during the installation, then use Database Configuration Assistant to create one after you have installed the software. For more information about using Database Configuration Assistant to create a database after installation, refer to the Oracle Database 2 Day DBA manual.

Available Installation Options

This release of Oracle Database provides Database Storage Options that you can choose during installation to simplify database administration tasks:

The following sections describe these options.

Database Storage Options

If you choose to create a database during the installation, then specify File System as the storage options for database files.

File System

If you choose the file system option, then Database Configuration Assistant creates the database files in a directory on a file system mounted on the computer. Oracle recommends that the file system you choose be separate from the file systems used by the operating system or the Oracle software. The file system that you choose can be any of the following:

  • A file system on a disk that is physically attached to the system

    If you are creating a database on basic disks that are not logical volumes or RAID devices, then Oracle recommends that you follow the Optimal Flexible Architecture (OFA) recommendations described in Appendix C and distribute the database files over multiple disks.

  • A file system on a logical volume manager (LVM) volume or a RAID device

    If you are using multiple disks in an LVM or RAID configuration, then Oracle recommends that you use the stripe and mirror everything (SAME) methodology to increase performance and reliability. Using this methodology, you do not need to specify multiple file system mount point for database storage.

If you choose the Custom installation type or the Advanced database creation option, then you can also choose to use the Oracle-managed files feature with the new database. If you use this feature, then you must specify only the database object name instead of file names when creating or deleting database files.

However, because new platforms and operating system software versions might be certified after this guide is published, review the certification matrix on the OracleMetaLink Web site for the most up-to-date list of certified hardware platforms and operating system versions. The OracleMetaLink Web site is available at the following URL:


If you do not have a current Oracle Support Services contract, then you can access the same information at the following Web site:


Multiple Oracle Homes

This product supports multiple Oracle homes. You can install this release or previous releases of the software multiple times on the same system, in different Oracle home directories.

Installing the Software on a System with an Existing Oracle Installation

You must install this product into a new Oracle home directory. You cannot install products from one release of Oracle Database into an Oracle home directory of a different release. For example, you cannot install release 10.2 software into an existing Oracle9i Oracle home directory. If you attempt to install this release into an Oracle home directory that contains software from an earlier Oracle release, then the installation fails.

You can install this release multiple times on the same system if each installation is installed in a separate Oracle home directory.
