there is some debate whether those can be effective

Changing port # is just security by obscurity , right?

Hi All,
We have full rack exadata server X5 version with 11.2.0.4 version DB running on
it.. We changed the port number of scan and local listener from 1521 to 1621.
I tried connecting to the database remotely using scan and default service with
port 1521 , connection is going through. I also tried connecting to the
database using scan and default service using 1621 port as well. With that also
I am able to connect. Should I ideally get my connection request with port 1521
rejected with some TNS errors?? Or is this is expected??
