About Database Installation Modes
You can create the Siebel Schema using one of two modes: standard or customized.
Standard Install
If you choose the standard installation option, you perform all installation tasks using the Database Configuration Wizard. A standard install creates a Siebel preconfigured database layout.
Customized Install
If you choose the custom installation option, you provide a storage control file that specifies the custom database layout that is most suitable for your Siebel deployment. You must create and validate the custom storage control file before performing the Siebel Schema installation using the Database Configuration Wizard.
