During advanced installations, you are prompted to make the choices listed in this section, in addition to the basic options. The installation process provides defaults for every choice.
The advanced installation choices are described here. However, advanced installation steps are not documented in this chapter. For more information, see the Oracle Database Installation Guide for your platform.
During an advanced installation, you are given the following options:
■ Install the sample schemas?
To complete the exercises in this book and related course material, you must install the sample schemas. This data is also used in most examples throughout Oracle Database documentation. Oracle recommends that you install the sample schemas.
This choice is a configuration option only during advanced installation. This option defaults to No during advanced installation. However, sample schemas are installed by default during basic installation.
■ What kind of storage mechanism do you want your database to use?
A database includes several files that store the user data, database metadata, and information required to recover from failures. As an administrator, you decide what kind of storage subsystem to use for these files. You can select from the following options:
– File System—This default option creates database files that are managed by your operating system's file system. You can specify the directory path where database files are to be stored. Oracle Database can create and manage the actual files.
If you are not certain of which option to use, choose the default selection of File System.
– Automatic Storage Management—This functionality enables you to define a pool of storage (called a disk group) in which Oracle automatically manages database file placement and naming. For environments with a large number of disks, this option simplifies database administration and maximizes
performance. Disk mirroring and striping are performed automatically.
Automatic Storage Management requires a separate instance to configure and manage disks groups. The installer guides you through the creation and launching of an Automatic Storage Management instance and its components.
For more information, see Appendix A, "Automatic Storage Management" and Oracle Database Administrator's Guide.
Installing Oracle Software and Database
– Raw Devices—This option enables you to manage your storage devices outside of the operating system file system by providing Oracle Database with unformatted physical disk space called raw devices. This method is primarily used in Oracle Real Application Clusters (RAC) environments. If you select this option, ensure that the raw devices have been created with an operating system command, and that they are not being used for any other purposes or by other Oracle databases.
■ What are your Database Management Options?
Here you specify whether to manage your database centrally or locally. The central deployment mode enables you to manage multiple targets, such as databases and application servers, from a single console. The local deployment mode can manage only a single database instance.
The central deployment mode requires a special agent to be installed on the database host. If no such agent is found, then this option is disabled.
If you are setting up a single database for the first time, it is recommended that you deploy Enterprise Manager locally, which is the default.You can later install additional databases and migrate your deployment mode to central management.
At the end of the interview, a summary window displays the options that you have chosen, the requirements for space based on those options, and the components that will be installed. If you have chosen to install a database, then this step is performed immediately after the software installation is complete.
Installing Oracle Software and Database
This section describes the basic installation steps. Most steps are common to all platforms and involve running the Oracle Universal Installer. Platform-specific steps are noted.
The following steps provide a summary of the installation process. For further assistance along the way, consult the online help or the Oracle Database Installation Guide for your platform.
1. Log on to your computer as a member of the administrative group that is authorized to install Oracle software and to create and run the database. Refer to your operating system-specific documentation or contact your system
administrator to determine whether you have the necessary privileges to install new software.
2. Insert the distribution media for the database into your computer. The Autorun window opens automatically. Click Install/Deinstall Products.
If downloading from Oracle's Web site, then follow the instructions on the site.
3. The Oracle Universal Installer Select Installation Method window appears.
Figure 2–1 shows what this window looks like on Windows.

4. You must now decide which type of installation to perform:
■ Basic Installation—Select this option to quickly install Oracle Database 10g.
This method requires minimal user input. It installs the software and optionally creates a general-purpose database based on the information you provide.
For basic installation, you specify the following:
– Oracle Home Location—Enter the directory in which to install the Oracle Database 10g software. You must specify a new Oracle home directory for each new installation of Oracle Database 10g.
– Installation Type—Select either Enterprise Edition, Standard Edition, or Personal Edition (Windows Only). Refer to "Basic Installation" on page 2-2.
– UNIX DBA Group (Linux and Unix only)—Specify the DBA group for your operating system.
– Create Starter Database —Check this box to create a database during installation. Oracle recommends that you create a starter database for first-time installations. You must enter a Global Database Name and Database Password for the SYS, SYSTEM, SYSMAN, and DBSNMP
administrator accounts. The Global Database Name is described in "Basic Installation".
To start the basic installation, click Next. The Preparing to Install progress bar appears.
■ Advanced Installation—Select this option to customize your installation. For example, use this method to install Oracle Real Application Clusters, to upgrade a database, to configure Automatic Storage Management, or to configure automated backups. Selecting this option steps you through installation steps not documented here. For more information about the
