RepDB* is a data management component for replicating autonomous databases or data sources in a cluster system. It has been initially designed in the context of the Leg@net RNTL project and further developped in the context of the ACI MDP2P project. RepDB* supports preventive data replication capabilities (multi-master modes, partial replication, strong consistency) which are independent of the underlying DBMS. It uses general, non intrusive techniques. It is implemented in Java on Linux and supports various DBMS: Oracle™, PostGreSQL and BerkeleyDB. It has been validated on the Atlas 8-node cluster and another 64-node cluster at INRIA-Rennes. In 2004, we registered RepDB* (together with the University of Nantes) to the APP (Agence pour la Protection des Programmes) and released it as Open Source Software under the GPL licence.
