connection lost contact if idle too long
Hi,
We have our Oracle server in one network segment which is safeguard by firewall,
everytime when I login to the Oracle from another network segment, and if the session left idle for around 10 mins,
it will "lost contact". The connection can keep connected if did not left idle too long. (i.e. query the database)
This thing won't happen if I move my pc to the same network segment as the Oracle server, the connection won't lost even I
left it idle for two days.
Is there anyone have the same experience?
What could be the cause of the problem? network or Oracle server?
Thanks
Vincent
