In the Data Intensive grid environment, researchers always try to avoid failures by improving the data availability with mechanism called replication. In this paper, data availability which is shown works towards efficient way of applying Object replication and its object replicas availability prediction and thus users are able to predict its dynamic replication status that decides replicas management and its performance in data grid. The proposed way of Availability prediction gives status of data availability at nodes and thus it gives data reliability information to the scheduler, in such manner our proposed scheme helps to make better jobs execution decisions with minimum jobs execution time and band width by considering account of some of the objective functions involved while data access. It is an eminent method to deal with object replicas utilization that can be improved jobs execution performance, and proposed method is an auspicious improvement over performance of replicas utilization without failures in data grid environment.
