          Hi,

          Not really a question specific to the SQL Developer tool. Better to search one of the other forums. For example, try reading through this...
          ERROR: ORA-12560: TNS:protocol adapter error

            Welcome to the forums but this forum is ONLY for sql developer questions.

            Please mark this thread ANSWERED and open a new thread in the Database General forum
            General Database Discussions

            When you post there provide your 4 digit Oracle version and information about how you are trying to connect.

            Your error indicates that your client is not configured properly to connect to the database.
