working fine Oracle database Express Edition starts up automatically when the system starts we need Oracle to start automatically on servers however on a standalone development system we may prefer to start Oracle only when it is required because Oracle when running takes a considerable amount of system resources you can manually start or stop the database using Windows services let's do this from the start menu open Windows services in the services application window select any service and press the o key to bring up the list of services that starts with the letter O right click the Oracle service XE and from the menu select stop to stop this service also stop the TNS listener service similarly you can right click the service name and select start to start a service you can also control
