Abstract
A method and a system for maintaining consistency of replicated files distributed over a plurality of independent processing slave nodes part of an application tier of a multi-tier client/server data processing system are described. The replicated files are distributed from a master node of a master tier. Upon reception of an update request to update a master database a new version of a replicated file is first generated and stored in a shared file system. A notification of availability of the new version is forwarded to a synchronizing slave node and broadcasted to all slave nodes. Each slave node preloads the new version of the replicated file from the shared file system and acknowledges successful completion. Upon reception of all acknowledgments in the synchronization slave node a notification of preloading achievement is forwarded to the master server which updates the master database.
