Neither the Oracle Forms client nor the Oracle database provide a way to track to track a cntrl+alt+delete key-press. Why? That key combination interupts the client connection so the client can no longer communicate with the database. The database will notice the broken connection after some time (this is controlled by an internal limit that Oracle does not allow us to control) but the database has no way to know whether this was: caused by:a broken or disconnected network cable; a power outage at the client, etc.
Your best way to manage this is by user training.
