Re: Port usage?
Don Oracle is doing the normal ting : it is using port 1521 for calls to find the listener and then calling back on another port to spread the load over multiple port's. This is done a port has a limited queue to hold in- and out- coming messages. If you what to use Oracle listener and database behind a firewall by a sql*net proxy for the firewall and the firewall is then able to handle sql*net without problems.

The Unix admin is asking two questions: 1) what Oracle is doing with the four ports 20,000 - 20,003 2) can he shut them down?

Re: Port usage?
we had the same problem and we found that oracle use the standard port only to make the initial connection. All the traffic after that is done on different ports. So you need to open the range that oracle use in the firewall.

Re: Port usage?
the firewall should use sqlnet proxy. most firewalls support it and if this one doesn't scrap it! only the initial connection is made on port 1521.
