JDBC connections use a "thin" connection that does not require tns. It uses either the server name and sid/service name to connect to the database.

Subject: Ports in listener.log


I have a 10.2 listener listening on port 1522, and see connections established using that. However, I also see connections coming in on other ports, that look like the increment by 1 each time. The connections are coming from a .net application on a windows server through IIS, and that server does not have a tns entry in tnsnames.ora. We removed it from there to specifically prevent connections to this database. Anyone have any idea how this could be happening?
