To access Oracle Enterprise Manager Database Control (Database Control) from a client browser, the Database Control console process dbconsole needs to be running on the database host computer. The dbconsole process is automatically started after installation. However, in the event that the system needs to be restarted, you can start it manually at the command line or start it as a service in Windows. You can also run commands to stop the dbconsole process or view its status. If the dbconsole process is stopped, it must be manually restarted before you use the Database Control console.

To start or stop, or to view the status of the dbconsole process from the command line:

1. Open a operating system command window and go to your Oracle_home/bin directory.

2. Do one of the following:

   • To start the dbconsole process, run the following command:

     ./emctl start dbconsole
             

   • To stop the dbconsole process, run the following command:

     ./emctl stop dbconsole
             

   • To view the status of the dbconsole process, run the following command:

     ./emctl status dbconsole
             

To start or stop dbconsole as a service on Microsoft Windows:

1. Do one of the following:

   • On Windows XP and Windows Server 2003, click Start, and then select Control Panel.

   • On Windows 2000 Server, click Start, select Settings, and then select Control Panel.

   The Control Panel window opens.

2. Double-click the Administrative Tools icon, and then double-click the Services icon.

   The Services window opens. Oracle Database services begin with Oracle. The dbconsole service is listed as OracleDBConsoleOracle_sid, where Oracle_sid is the system identifier (SID) for your database instance. The status of this process (either Started or Stopped) is listed in the Status column.

3. Double-click the OracleDBConsoleOracle_sid service.

   The service properties window opens.

4. In the Startup Type list, ensure that either Manual or Automatic is selected.

5. Do one of the following:

   • To start dbconsole, click Start, and then click OK.

   • To stop dbconsole, click Stop, and then click OK.
