ABSTRACT:
One aspect of the invention is a method for managing redundant objects in a distributed object system. A transaction service runs on a computer. At least two copies of the instance variables of a distributed object are maintained in a separate database. The distributed object (46) has a polymorphism of an interface object instantiation method. At least two copies of an interface object (48) are instantiated wherein each interface object (48) is associated with one of the copies of the instance variables of the distributed object (46). The interface objects (48) are instantiated using the polymorphism. A list of interface objects (48) is maintained with the distributed object (46). Each copy of the instance variables of the distributed object (46) are modified by traversing the list of interface objects (48) and sending a message with modification parameters to each interface object (48) on the list.
