Configuring Oracle Database Security Settings
Use Oracle Database Configuration Assistant (Oracle DBCA) commands to change security settings after installation.
To enable or disable the database security configuration after installation, you
must use command-line Oracle Database Configuration Assistant (Oracle DBCA) options. By
design, the Oracle DBCA graphical user interface (GUI) does not have the option to
enable or disable secure configuration.
