摘要

An information transfer system transfers stimuli, each having an associated operation identification value, among processes. The information transfer system includes a queue database to hold stimuli and associated information and a queue manager to control receipt of the stimuli in, and transmission of the stimuli from, the queue database. The transfer of stimuli first requires a registration operation. If the process has previously used the information transfer system and has not performed a deregistration operation, the queue manager assumes a failure has occurred and provides to the process recovery assisting information, such as the last stimulus the information transfer system received from or transferred to the queue database.
