Abstract :
In this paper, we propose, present and analyze the behavior and the performance of a reconfigurable algorithm for shared objects consistency management in distributed systems. Object sharing allows nodes to concurrently/parallel access a same set of replicated objects. However, it is necessary that the nodes know when and how to do these accesses, avoiding inconsistencies in the objects state. The RCA (reconfigurable consistency algorithm) is a reconfigurable algorithm that guarantees the objects consistency. This algorithm modifies its behavior and structure according to the changes in the workload and distributed systems parameters. The paper shows that: the use of RCA generates flexibility and improves the performance in 30%, on average
