We are installing some intrusion detection software on our most critical servers and as part of the baseline we have to identify every port Oracle is using and documenting what the process is and why it's using it. I've been able to find documentation on most of the Oracle processes running, but the Server Processes for the database and ASM have been difficult to find documentation on. The software detected server processes running UDP over ports ranging from 9066 to 65498. This is a RAC system. How can we find documentation how how the processes are named and what ports they have the potential to use?
Thank you.
