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.
Completing postinstallation tasks: Chapter 4 describes recommended and required postinstallation tasks.
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.
You can choose different installation methods to install Oracle Database, as follows:
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
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.
Note: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:
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.
Note: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.
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:
Oracle provides the following preconfigured database types that you can create or customize during the installation:
Refer to the online help provided by either Oracle Universal Installer or Database Configuration Assistant for a description of these preconfigured database types.
Oracle Universal Installer runs Database Configuration Assistant in one of two modes, depending on the choices that you make during the installation:
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.
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.
Note: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.
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.
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.
If you choose to create a database during the installation, then specify File System as the storage options for database files.
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.

This section contains information that you must consider before deciding how to install this product. It contains the following sections:
The platform-specific hardware and software requirements included in this installation guide were current at the time this guide was published. 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:
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.
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.
