    I have created a local DB (name "test"). Now I need to create a Listner and and a service.
    First I created a listner called LISTNER with protocol TCP/IP, Host and port 1521. After I created a service with this parameters:I used the TCP/IP protocol, host,port 1521 service name the same of my DB (test). When I check the service I have this error:

    ORA-12541: TNS: no listner.

    The listener service should have been started by the OUI at installation with a call to the Net Configuration Assistant (NetCA). You can always run this manually:

    Start->All Programs->Oracle Database ...->configuration and migration tools-> net configuration assistant

    This will create, configure and start your LISTENER service.
