DEADLOCK CONTROLLER AND METHOD FOR CONTROLLING THE SAME DEVICE AND DEADLOCK CONTROL SYSTEM AND MEDIUM WITH PROGRAM FOR CONTROLLING THE SAME DEVICE RECORDED

摘要

PROBLEM TO BE SOLVED: To realize efficient deadlock control with resources arranged for each application as objects to be controlled. SOLUTION: A deadlock control system is provided with plural task computers 110 and 120 having resources prepared for each application (processing) or the like and an exclusive control computer 100. When a request for the user of claim resources 114 of the computer 110 is transmitted from the computer 120 to the exclusive control computer 100, the computer 100 discriminates whether or not the claim resources 114 are the self-occupied resources of the computer 110 (a step 801), and discriminates whether or not the self-occupied resources (money reception resources 124) of the computer 120 are requested by the computer 110 (a step 802). At the time of discriminating that the task computer 110 and the task computer 120 mutually request their self-occupied resources, the computer 100 notifies the task computer 120 that the state reaches a deadlock.
