It looks like port 1521 is being replaced by 2483, is 2483 operational for
Oracle DBs 12 and above. The document <https://tinyurl.com/rymtcjg> is
bit confusing for me: "This port number can change to the officially
registered port number of 2483 for TCP/IP, and 2484 for TCP/IP with SSL"
Also, can ports closer to 2483 be used by sites that are security
conscious since it is recommended not to use default ports for security
conscious installations.
