Patent number: 6941556Abstract: 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.Type: GrantFiled: May 24, 1999Date of Patent: September 6, 2005Assignee: Sun Microsystems, Inc.Inventors: Peter B. Kessler, Swee Boon Lim, Peter Vanderbilt, Michael L. Powell, Li-Wen Chen, Dwight F. Hare, Alan Snyder

Patent number: 6769125Abstract: 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.Type: GrantFiled: September 28, 2001Date of Patent: July 27, 2004Assignee: Sun Microsystems, Inc.Inventors: Anthony W. Menges, Kenneth M. Cavanaugh, III, David M. Brownell, Robert B. Hagmann, Dwight F. Hare, Peter Vanderbilt

Patent number: 6353860Abstract: 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.Type: GrantFiled: December 23, 1997Date of Patent: March 5, 2002Assignee: Sun Microsystems, Inc.Inventors: Dwight F. Hare, Robert B. Hagmann, Michael L. Powell, Alan Snyder, Peter Vanderbilt

Patent number: 6336147Abstract: 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.Type: GrantFiled: November 12, 1997Date of Patent: January 1, 2002Assignee: Sun Microsystems, Inc.Inventors: David M.

Patent number: 5793965Abstract: 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.Type: GrantFiled: March 22, 1995Date of Patent: August 11, 1998Assignee: Sun Microsystems, Inc.Inventors: Peter Vanderbilt, David M. Brownell, Alain Demour, Dwight F. Hare, Michael L. Powell
