Abstract
A mechanism is described for protecting a server against invalid usage of proxy objects after malfunction of a server and also for transparently re-creating proxy objects in a client of a client-server distributed processing system. A proxy class is used that has additional attributes indicating the name of the target object in the server, an indication as to whether the name is presently valid and an alternate pointer to the target object. A proxy register object in the client maintains pointers to all the proxy objects which point to objects in the server. On malfunction of the server, and consequent invalidity of the proxy objects, the proxy register object causes all proxy objects to be refreshed.
