Hey, the other thing you could do, if you know some identifying information for these sessions, like OSUSER, machine/terminal, client_info etc, you could setup a LOGIN TRIGGER that enables a 10046 trace and capture any/all SQL executed in the session. Some apps (like PeopleSoft) will populate client_info so it makes it easier to trace one session instead of all the connected sessions. Maybe you have something available to you that will enable you to create a limited trace on a few sessions.
