摘要：
The invention concerns a method of synchronizing a distributed system comprising a server (2) having a master data base (21) and a set of clients (31 to 35) having respective client data bases (41 to 45), as well as a server and a computer program product for executing this method. The client data bases (41 to 45) are incrementally updated from the master-data base (21) of the server (2). A trace of transaction (22) is maintained at the server (2) for recovery. The server (2) synchronizes the client data bases (41 to 45) in case of a failure by coordinated rollback transactions from the trace (22).
