Re: Listener configure - port 1521 - how not to handoff to a higher port???

Hi George,
If you're using Oracle on Windows there is a registry setting USE_SHARED_SOCKET which when set to TRUE will force the listener to receive and respond only on port 1521 - great for strict firewall situations! I'm unsure if there's a *nix equivalent.

Cheers,

Stuart.
