Can I know which port that oracle client use for connection?

[Quoted] The problem I face is the jdbc connection broken several time a day in my servlet application. I think that the cause is every several hour, the server will ping the client tosee if it still alive . If the client is un-reactable, the server will disconnection it. As my client connect to internet through a firework so that all incoming resquest is blocked. Thus, oracle server can't ping the database and close the connection. Because of this, I would like to know is there a way that I can know the port of jdbc client use for connection? Is it request the OS to get a free port or is it same as oracle server? (1521) Please tell me how can I know which port oracle client use so that I can open that port, thx Received on Mon Dec 25 2000 - 07:20:38 CET
