Answer 1

The database and the Oracle software are on the same computer, so I don't have to use remote connection. I've checked the listener and the database name is on the list (protocol: IPC, name: ORCL). On the other hand the name of the database is the default name (ORCL), and when I first create the database (with the Database Assistant tool) I've checked the option "Add to the listner". I think that is enough to be sure that the db name is on the list. But still I have the error. Moreover, when i start the service Oracle Tnslistener80 (is this the service, right?) it starts correctly, but after one minute it automatically stop.
Thank you for the reply
