摘要： A number of methods, apparatus, and data structures are disclosed for managing computer processes. In one aspect, a daemon process which manages server processes includes an active server table and a locator service. The locator service can look up and register server processes in the active server table. Furthermore, the locator service can start up server processes. In some embodiments, the locator service includes a look-up object and a server process registration object which perform the tasks of the locator service. In other embodiments, methods for managing server process such as starting and registering the server processes are taught. In one specific method, a daemon process performs a variety of steps in response to receiving a look-up call for a target object. These steps include obtaining a server identifier for the target object, determining the state of a server process, and returning addressing information corresponding to the server process under which the target object will activate. In related method aspects the daemon process will start the server process if it isn't running and/or wait until the server process is running to return the addressing information. In a separate method aspect, a server process self-starts; receiving an object reference for a desired target object, receiving a server process identification number, creating a communications port for itself, forming addressing information for itself, obtaining an object reference for a server process registration object, and registering itself by calling the server process registration object to invoke a register new process operation.

摘要： A variety of methods, apparatus and data structures for managing collections of objects are described. In one aspect of the invention, an object that is intended for use in a distributed object operating environment has a structure including a group designation, a co-activation designation and a co-process designation. The group designation is arranged to identify a group to which the object belongs. The group is defined as a collection of objects which share a common persistent state. The co-activation designation is arranged to identify a co-activation set to which the object belongs. The co-activation set is a collection of objects which are to be activated at the same time. The co-process designation is arranged to identify a co-process set to which the object belongs. The co-process set is a collection of objects which are to be activated within a single process. A various embodiments, a variety of methods of utilizing one or more of these designations to facilitate efficient operation of a distributed computing system are also described. In some applications, a particular object may be conceptually divided into a plurality of sub-objects, with each sub-object having its own portion of persistent memory. In this embodiment, the particular object may only be invoked as a whole, but the object is provided with a mechanism for accessing the selected sub-object in response to a call from a client object that invokes the object and identifies the sub-object in a sub-object field of an object reference that refers to the object. When sub-objects are use, the object references may be arranged to include a host identifier, an object identifier and a sub-object field.

摘要： A method of checking the type of an object located on a remote computer in a distributed object environment computing system is disclosed. Initially, a type checking method to determine whether a remotely located object is of a specified type is invoked. In the invocation, a target interface identifier is included as an argument. A determination is then made as to whether the target interface identifier is equal to or a base for an apparent interface identifier held by a proxy object located on the first computer. If the target interface identifier is determined to be equal to or a base for the apparent interface identifier, an affirmative indication to that effect is returned to the client process. If not, then the target interface identifier is then compared to a real interface identifier. In many embodiments, a call to the server host will have to be made in order to determine the real interface identifier. In some embodiments, a local cache memory can also be provided to store the results of such inquiries. The target interface identifier is then compared to the real interface identifier and a determination is made as to whether the target interface identifier is equal to or a base for the real interface identifier. The result is then returned to the client process. A method of checking the type of an object and additionally returning an output proxy object is also disclosed. The output proxy object may be the original input proxy object that has been widened to the class associated with the target interface identifier, or may be a newly created proxy object that is of the same kind as the input proxy and of the same type as the target interface identifier.

摘要： A system and method provides dynamic and static type support for multiple definitions of individual types in a distributed object environment. Fully scoped object names incorporating prefixes are used to distinguish objects. The fully scoped names are used for both dynamic type determination through an interface repository and for statically compiled types in client and server stub routines. In the interface repository, a prefix naming context is provided for each root interface definition language context, allowing multiple definitions for objects with the same interface definition language object name, where each such definition resides in a separate prefix naming context. In one embodiment, the prefix naming contexts are defined by prefix interface definition objects. In another embodiment, the fully scoped object names are embedded by an interface definition language compiler in stub and skeleton code routines. RRS.

摘要： A method and apparatus for managing connections between objects in a distributed object system includes a method and apparatus for terminating connections between objects. In one aspect, the method for terminating a connection, a connection end message is sent from a server to a client indicating to the client that the server will no longer accept requests before the connection is terminated. Preferably a connection end code is included with the connection end message. In another aspect, the invention includes a method for making connections between objects are formed by intelligently closing existing connections that meet the criteria of being established and across which no unfulfilled requests or unforwarded replies are pending. If several connections meet these criteria, the oldest unused connection is terminated. The methods and apparatus described provide for the creation and termination of connections efficiently and robustly by allowing the controlled shut down of connections between clients and servers without invoking an error state.
