Forced deactivation is specified with the TYPE=FORCE operand of the VARY INACT command. When forced deactivation is requested, all of the actions described for immediate deactivation apply. An application program notified of the termination of a session with a deactivated logical unit might have to complete the session termination (depending on which user exits have been coded for the program) for the deactivation to be completed. Forced deactivation can be used when immediate and normal deactivation are not successful.
