1. Creating a Database with DBCA
DatabaseConfiguration Assistant (DBCA) is the preferred way to create a database,because it is a more automated approach, and your database is ready to use whenDBCA 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 asa standalone tool at any time after Oracle Database installation. You can runDBCA in interactive mode or noninteractive/silent mode. Interactivemodeprovides a graphical interface and guided workflow for creating and configuringa database. Noninteractive/silent mode enables you to script database creation.You can run DBCA in noninteractive/silent mode by specifying command-linearguments, a response file, or both.
