In this work we present a protocol ensuring the e-Transaction guarantee (i.e. a recently proposed end-to-end reliability guarantee) in a Web based, three-tier transactional system. The protocol does not need any coordination among the replicas of the application server, thus exhibiting negligible overhead in normal behavior. Additionally, it achieves highly efficient fail-over especially for the case of back-end database employing Optimistic Concurrency Control (OCC), namely a type of concurrency control well suited for data access performed via Web. We also present a comparative discussion with existing solutions and a quantitative analysis of the proposed protocol, which clearly quantifies its benefits, in terms of reduced user perceived latency, especially when employed in combination with OCC.

Abstract
In this work we present a protocol ensuring the e-Transaction guarantee (i.e. a recently proposed end-to-end reliability guarantee) in a Web based, three-tier transactional system. The protocol does not need any coordination among the replicas of the application server, thus exhibiting negligible overhead in normal behavior. Additionally, it achieves highly efficient fail-over especially for the case of back-end database employing Optimistic Concurrency Control (OCC), namely a type of concurrency control well suited for data access performed via Web. We also present a comparative discussion with existing solutions and a quantitative analysis of the proposed protocol, which clearly quantifies its benefits, in terms of reduced user perceived latency, especially when employed in combination with OCC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
