The listener has started correctly and its status shows OK!
I enter the correct IP address of the server in the
listener.ora file, not
But when I try to connect to my database by entering the following in SQL Developer:
user: system password: ******* host: 126.96.36.199 port: 1521 SID: orcl
I get this error:
Statut : échec -Echec du test : Erreur d'E/S: The Network Adapter could not establish the connection
I think that I need to open the 1521 port but I don't know if this is the problem?
