Thanks Tom.

Could the same be true for .NET?  We're not using jdbc connections.

Sherrie,

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



Oracle 10.2.0.3
HP-UX

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?
