METHOD AND SYSTEM FOR SYNCHRONIZING SOFTWARE MODULES OF A COMPUTER SYSTEM DISTRIBUTED AS A CLUSTER OF SERVERS, APPLICATION TO DATA STORAGE

摘要

In this method of synchronizing software modules (14i, 14j, 14k) of a computer system distributed as several servers interconnected in a network, each software module executing on a server of the computer system for managing a description data set describing a service, at least a part of the description data (Di, Dj, Dk) is replicated on a plurality of software modules. The method comprises the following steps: - execution (100), on a first software module (14i), of an action (A) acting on a description data item (Di), - transmission (102) of a synchronization message (M) identifying the action to the set of other software modules (14j, 14k) of the computer system comprising a replication (Dj, Dk) of this description data item, - on receipt of this message (M) by any one of the software modules concerned, execution (104, 106) of the action identified on this software module in such a way as to act on the replication of the description data item situated on this software module.
