Hello All,

I am repeatedly receiving the following error into the alert log of the
database on phx11cn1 server. Does it mean some process is trying to connect a
database on the HOST=10.72.10.53? How to identify which process is trying to do
that. The listener on HOST=10.72.10.53 has the port as 11021 and not sure what
process is trying to use a hardcoded listener port as 1521 to connect to the
database on HOST=10.72.10.53.

Any idea how to identify what process is generating this error message.

Thanks,
Ashoke
