Session Pool Logoff Processing
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 will process the pseudo‑logoff without Teradata DBS communication (cleanup is suppressed).
When the pseudo‑logoff is completed, the TDP will issue 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.
