Replication can improve the reliability of a computational grid. Replication allows a resource to be used even if some of the instances are not running or are inaccessible. However the challenge is how maintain consistent the replicas. In this paper, the authors propose and evaluate "Oriented Consistency" (OC), a weak consistency algorithm for the dissemination of changes considering application-level in computer Grids. This algorithm is optimizing the propagation of changes introducing a preference for nodes in virtual organizations of the grid.
