Creating a Database with DBCA

Database Configuration Assistant (DBCA) provides a graphical interface and guided workflow for creating and configuring a database. It is the preferred way to create a database, because it is a more automated approach, and your database is ready to use when DBCA completes. DBCA can be launched by the Oracle Universal Installer (OUI), depending upon the type of install that you select. You can also launch DBCA as a standalone tool at any time after Oracle Database installation.

See Oracle Database 2 Day DBA for detailed information about creating a database with DBCA.
