Abstract

Data Grids are currently solutions suggested meeting the needs for the scale large systems. They provide whole of resources varied, geographically distributed of which the goal is to ensure a fast access and effective to the data, to improve the availability, and to tolerate the breakdowns. In such systems, these advantages are not possible that by the use of the replication. Nevertheless, several problems can appear with the use of replication techniques, most significant is the maintaining consistency of modified data. The strategies of replication and scheduling of the jobs were tested by simulation. Several simulators of grids were born. One of the important simulators for Data Grids is the OptorSim tool. In this work, we present an extension of OptorSim by consistency management service of replicas in data Grid. This service is based on hybrid approach, combining between pessimistic, optimistic approaches and economic model, articulated on a hierarchical model.
