Use the Database Configuration Assistant (DBCA) Management Options window to set up your database so it can be managed with Oracle Enterprise Manager. Oracle Enterprise Manager provides Web-based management tools for individual databases, and central management tools for managing your entire Oracle environment.
To manage your database locally, select Configure Enterprise Manager (EM) Database Express.
If the Oracle Management Agent is installed on your host computer, then you can choose central management by selecting Register with Enterprise Manager (EM) Cloud Control for centralized management and then specifying the host and port for the Management Service and the EM Admin username and password.
