    Data Base Doesn't connect

    4255580

      Hi! i downloaded sql developer yesterday. I have tried to run a data base conexion since yesterday. That is the error :  Error de E/S: The Network Adapter could not establish the connection .Código de proveedor 17002

      I was searching on google a lot, things about listener and tnsname, but when i downloaded the archive.zip i have no listener.ora or something like that, i was trying the command lsnrctl status, but doesnt exist on path because i have no listener, and i have no oracle folder too, just the unzip folder. I have to make a work for the university and i dont know how to do. Anybody has a solution?
      Thanks
