Hi!

1. You can set idle_time profile option in server, to automatically disconnect sessions idle for some time.
2. You can set sqlnet.expire_time to some minutes or hours, that Oracle would probe all sessions over some interval and disconnect the ones which don't have a corresponding client anymore
3. You'r app should commit at the end of transactions, it should not lock too many rows just in case, if possible.

Tanel.
