SOFTWARE SYSTEM HAVING REPLICATED OBJECTS AND USING DYNAMIC MESSAGING, IN PARTICULAR FOR A MONITORING/CONTROL INSTALLATION OF REDUNDANT ARCHITECTURE

The invention relates to an object-oriented software system having replicated objects and which makes it possible to control a monitoring/control installation of redundant architecture and comprising at least one first processor (1) and one second processor (1'). The software system (2) comprises software objects (3) intercommunicating by means of messages via a dynamic object messaging mechanism. A replica (2') of the software system (2) is contained in the second processor (1'). Certain objects (3) of the software system (2) are marked and the dynamic object messaging mechanism (5) includes monitoring means (51) for identifying an object message addressed to a marked object, and means (52) for passing on the contents of the object message, in the form of a network message, to the second processor (1'). In response to the network message, the dynamic object messaging mechanism (5') in the second processor (1') activates the replica (3') of the marked object (3). The invention enables a semi-active redundancy technique to be implemented.
