Oracle Coherence cluster communication; TCP/7574 is assigned to the service, though deployments commonly use UDP on this port.
port 7574 as Oracle Coherence Cluster Service →Which one is on your host
The registry says what 7574 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.
- linux
ss -ltnp | grep ':7574\b'- macos
lsof -nP -iTCP:7574 -sTCP:LISTEN- windows
netstat -ano | findstr :7574
On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.
A port number is not a service. Anything may listen on 7574 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
