If there is a logoff or if an in-doubt session exists, the TDP uses “pseudo-logoff” processing.
The logoff can be initiated thorough an application request or the abnormal end of an IMS TCB.
If the session is in-doubt, the TDP processes the pseudo-logoff without database communication (cleanup is suppressed).
When the pseudo-logoff is completed, the TDP issues the TDP0868 message and remove the session from the session pool.
This in-doubt transaction can be terminated using only automatic or manual in-doubt resolution.
