if you doubt that a session hangs, start another sqlplus session and query v$session_wait. Check these things:
1 Is event changing for the hang session?
2 If event is not changing, is seq# changing for the hang session?
3 If both are not changing, what's the event name? the issue might be with that event..

depending on these...you get some idea.

and other method in unix ( may not be much effective for sqlplus sessions and internal database activities..but very useful in other scenarious ) is to use truss command.
