What is Port 2483?
Port 2483 is used by Oracle Database for client connections using the native TCP protocol without encryption. It serves as an alternative to the traditional port 1521, providing the same Oracle database access capabilities. Organizations migrating from port 1521 may configure listeners on this IANA-registered alternative.
