Enterprise Manager console for oracle 11g on windows server 2008

Posted on 2011-02-28

I installed Oracle 11g R2 on virtual server with windows server 2008 on it. The installation went fine, global database xyz was created on domain and a URL to access Enterprise Manager for xyz instance was created. I was able to open the link. But when I go to "Database instance: xyz" section, it says database instance is open, but the listener is unavailable and agent connection to instance failed. (ORA-12541)

I fired command lsnrctl and checked the status - which is "started". but the service instance is "CLRExtProc". I am not sure, but shouldn't it be xyz ? If yes, then how to change it ?

That's not the service for your instance. You ought to see xyz (or whatever service_name you have chosen). Please send the full output for lsnrctl status AND lsnrctl services. Does your instance have the parameter local_listener set??

>>but the service instance is "CLRExtProc".

from a SQL prompt as a privileged user:  ALTER SYSTEM REGISTER;

then do another: lsnrctl status

I executed ALTER SYSTEM REGISTER COMMAND and did another lsnrctl status/service. Same output :

Please post your listener.ora file.

You need to setup a TCP listener. You ought to have a sample listener.ora under %ORACLE_HOME%\network\admin\sample\listener.ora, copy/paste the TCP part, using port 1521, and stop/start the listener. Note you've not given the output for lsnrctl services, but the thing is that you need the TCP listener, or else the instance won't find it when it wants to register.
