Unable to start DB console service I'm using Oracle 11g database in a Windows environment. I've installed Oracle database software only, but now I'm in need of enterprise manager. Initially I tried to start them using the below commands.

C:\&gt;set ORACLE_UNQNAME=testdb

C:\&gt;emctl status dbconsole


This didn't work as my service for DB console was not up. Then, I tried starting the service which showed up the following error. 





Can anyone please help me in resolving this error?
Make sure you're running the CMD window "As Administrator".
You will also need to set the ORACLE_SID variable.

 set ORACLE_SID=MyOracleSID
 emctl start dbconsole


It should provide a more detailed error message at this point, if it does fail.
