Replication can improve the reliability of a Computational Grid. Replication allows a resource to be used even if some of the in-stances are not running or are inaccessible. However the challenge is how maintain consistent the replicas. In this paper we propose and eval-uate "Oriented Consistency" (OC), a weak consistency algorithm for the dissemination of changes considering application-level in computer Grids. The main aim of this algorithm is optimizing the propagation of changes introducing a preference for nodes in Virtual Organizations of the Grid. The algorithm has been simulated over ns-2, and evaluated with several simple and complex spatial distributions of the users. The impulse response of the algorithm has been characterized. We conclude that considering application parameters such as clustered users of Vir-tual Organizations in the event or change propagation mechanism gives a surprising improvement in the speed of change propagation perceived by most users. In other words, it satis¯es the greatest number of users in the shortest amount of time.
