Oracle probably has a connection time limit.  Maybe you should shut the db
connection when you are finished with it and reopen it when you need it again.
If you are worried about performance then you should be using a database pool.
Tomcat 4 comes with tyrex which can do that for you.

The database is running in a third database and there are in the same
network. Is there any way to say oracle that the connexion is still active?
