Control device and control method information system

Abstract

A technique of performing concurrency control of policies is provided, which makes it possible to efficiently utilize resources of an overall information system. According to the present invention, a policy execution device creates a list of components of a application system which are influenced by execution of an action of a policy instance, for respective policy instances. If trigger conditions of another policy instance are newly met during execution of a policy instance, the policy execution device compares a list of components of the policy instance presently being executed with a list of components of the policy instance whose trigger conditions are newly met. If there are no common components in the lists, the policy execution device executes the policy instance whose trigger conditions are newly met, and if there are common components in the lists, the policy execution device suspends the policy instance whose trigger conditions are newly met.
