Robust Replication Control Using Primary Copy Method
Niraj Sharma · Purdue e-Pubs (Purdue University System) · 1988
A primary site copy based replication control method is presented.It uses the topology of the network to detect partitioning when a link: or a node becomes faulty.The proposed method.ensures that the one-copy-serializability criterion is met under partitioning.We increase availability by allowing a primary copy to shift its locations to a more suitable partition and also by creation of new copies under partitioning if the number of copies is below a safe limit When partitions merge, the algorithm destroys the new copies generated under faults.
