How to start Oracle enterprise manager on Windows 64 bits I have installed Oracle 11g on my pc. It has installed fine and everything went fine. 

After restating pc, https://localhost:1158/em is not connecting.
The listener is ok and running fine. 

How can I resolve this problem?

If I try to start the OracleDBConsoleorcl it pop up an error massage that the OracleDBConsoleorcl could not start on local windows
You need to start the service, e.g. 

net start OracleDBConsoleorcl 


The service name might be different on your system, but it usually starts with OracleDBConsole and then contains the service name of your database. 

If you want it to always run, set the service start automatically through the control panel.
