Abstract

PURPOSE: To make it possible to prevent easily a system from breaking down by queuing programs in a reservation state when a program error occurs during the reservation and by making the file free when a recovery process ends.
CONSTITUTION: If a fault occurs during file maintenance after reserve R is made with a program started, the file is reserved until a recovery process ends. As a result, any other program can not use the same file, which is made into free-F state when the recovery process ends without making an irrational release. Consequently, the system down can be prevented easily.
