1. On the Select Installation Option page, select one of the following options:

   • Create and Configure a Database: Provides you with the option to create a database using a preconfigured database template designed for particular system load demands, such as an online transaction processing (OLTP) database, or a decision support or data warehouse database.

   • Install database software only: Installs Oracle Database software; you must complete the database configuration after the installation completes using the installed utilities.

   • Upgrade an existing database: Upgrades an existing database.

2. Optional: If you are installing Oracle Database software, then Oracle recommends that you use a preconfigured database option, or select the Advanced option on the Select Configuration page, and configure a custom starter database.
