Resolving or serializing conflicting update requests is the main challenge in large scale deployment of replicated databases. In this paper, we propose the first token based dynamic primary copy algorithms for resolving conflicting requests among different sites of replicated databases. The contribution being reduction in the number of messages required per update request. � 2009 Springer.Book chapter
