Oracle Universal Installer - Oracle 10g/11g Data and Database Management Utilities - page 307

This installation mode optionally creates a default database named the Starter
Database. This database is created using a standard file system and the same
password for all users. The database will have the Enterprise Manager DB Control
Console configured using either the default 1158 (first port assigned for Enterprise
Manager) or the first available port starting with 5500.
This easy installation mode installs an Enterprise Edition RDBMS by default
(this can be changed at the first screen shown), and other options that may require
additional licenses.
Licensed installed options
When performing an Oracle installation, the reader is encouraged to verify
the options installed. The user must make sure the installed software matches
the licensed software listed in the license agreement. If a default installation is
performed , it is very likely that there will be more options installed than those
that the user is authorized to install. Oracle publishes the product options that are
available for each different Oracle Edition at http://www.oracle.com/database/
product_editions.html . In case of doubt, contact your Oracle representative.
OUI Advanced Installation
The Advanced Installation option is a more comprehensive installation method. It
allows the user to select different passwords for the administrative accounts, define
the file storage method, specify custom initialization parameters, and specify the
products and languages to install, among other features.
In the Advanced Installation option, you can customize what to install and what
not to install. You can use the Advanced Installation system by choosing the Custom
option in the Select Installation Type window. A customized installation should be
used in cases when you want to install specific components. You can also perform
installations for ASM, which requires no database, or install the Advanced Security
Options. Here you can also choose which language your Oracle Home will support
by clicking on the Product Language button.
