  • Abstract Recently, personal workstation and local area network come to
    life of people. This paper attempts to combine this type of
    computing power to let people to construct a
    distributed application by use of an object based system. This
    system which is called distributed object manager can let
    people create an object, destroy an object, migrate an
    object, etc. The RPC ( Remote Procedure Call) is used as a
    message passing mechanism between any two objects and we
    establish the system using the client-server model. In this
    paper, we first introduce the life cycle of an object to
    discuss the state transition of an object, then we discuss the
    activities of object management in detail, including long,
    short and medium life cycle model, object naming, object
    creation, object destruction, object invocation, object
    migration and object locating. There are many problems in this
    type of system we must solve. Because it is important to keep
    track of objects in this system, we use an object name server
    to serve as this purpose. The object name server keeps all
    the informations of an object. Checkpointing lets the
    object survive the disaster when the machine crashes. When
    an object is migrated, there may be an invocation failure.
    Besides the object name server is used to keep track of the
    location of an object, forwarding address and the object
    locating algorithm are used to locate the invoked object
    because it may have been migrated. At last, we show our
    experiences of constructing this object manager. We will
    discuss and compare the pros and cons of its methods.
