PROBLEM TO BE SOLVED: To provide a method and device for managing a contention between users related to an access to a plurality of resources in a multisystem cluster. SOLUTION: This management method is so executed that each user identifies a contention chain with a resource which is possessed by a former user (or users) in the chain and the system resource is allocated to the user (or users) positioned in the head of the chain similar to a case where its necessity is, at least, the necessity of a waiter who is in the most urgent in the chain. Even if the data flow between systems is the minimum and no system has a complete view related to a cross system contention, the contention data necessary for the optimal resource allocation are effectively distributed to the system cluster whole region.
