An object-oriented type information managing system includes a network control system and a network managing system, the network control system includes an upper control object, and the network managing system includes a plurality of processes each having one or more objects. One object is used as a relay object for receiving a request message from the upper control object, and other objects are used as request message destination objects (or, control target objects) managed by the relay object. Each destination object returns a response message. Further, at least one process in the plurality of processes comprises a reply object for receiving the response messages sent from the destination objects and directly sending them to the upper control object.

A data storage and management apparatus for storing and managing data of an object as a persistent object in a data storing system. When storing an object in the data storing system, information on complexity of data of at least one attribute of the object is recorded in the apparatus, and data of each of the at least one attribute of the object is stored in a first table in the data storing system when the data of the attribute is not complex data, and in a second table in the data storing system when the data of the attribute is complex data. When manipulating data of an attribute of the object in the data storing system, the above information on complexity is referred to, and manipulation is performed on the first table when the data of the attribute is not complex data, and on the second table when the data of the attribute is complex data.

An object management system and data processing system which enable the containment relationships among a plurality of resource managers to be changed without affecting client applications which use services of those resource managers. A tree manager maintains tree structure data that defines the containment relationships among resource managers, together with identification data that is used to distinguish between them. From this tree structure data, an object manager builds a containment tree to grasp the containment relationships among the resource managers. When a client application issues an operation request to one of the resource managers, a message processor receives and forwards it to the object manager. The object manager then searches the containment tree to find identification data of a relevant resource manager for which the received operation request should be destined, thus sending the request to the found destination resource manager. This centralized approach of object management facilitates addition and removal of resource managers to/from the tree structure data.

A distributed processing system wherein client-side process is simplified and system reliability is improved. An information transmission requesting section makes a request for transmission of information, and an information providing section provides received information to a user. An information management section manages the information, and an information relaying/transmitting section relays the information to be transmitted to a client application. An account authentication section verifies authenticity of account of the client application, and an information storage section stores the information. After the authenticity is verified, a service application control section controls the start and termination at logon and logoff, respectively, of a service application corresponding to the client application.
摘要:
In a message control apparatus for transferring messages between objects which belong to different processes, a message distributor distributes messages to queue buffers provided for each of target objects, and a thread controller simultaneously prepares a plurality of threads less than a maximum thread allocation number predetermined for each of processes and the target objects and takes out the messages to be given to a corresponding target object. Also, the maximum thread allocation number corresponding to a CPU serviceability ratio in the processes can be designated, and a part of the thread allocation number of the target objects with few thread number used is allotted to the maximum thread allocation number of the target objects with many thread number used.

A method of controlling objects in an information processing system includes the steps of representing objects by a tree having a hierarchical structure, providing each of the objects with a first operation-target flag which indicates whether a corresponding object is a target of a given operation, and performing the given operation on an object upon receiving of an object handling request for the given operation only if the first operation-target flag of the object indicates that the object is a target of the given operation.

The present invention provides a collaboration system that reduces communication traffic, is platform- and OS-independent, and has high versatility. There are provided a collaboration server connected with a plurality of terminal apparatuses through a network for obtaining, retaining, and distributing a Web page as a work screen used in collaborative work among the terminal apparatuses, and a chat server for managing chat sessions. The collaboration server participates as a chat client in a chat session managed by the chat server and distributes an operation instruction concerning the work screen as a chat message to each terminal apparatus. The work screen is reloaded into each terminal apparatus according to the operation instruction to allow the collaborative work to progress.
摘要:
A method for structuring a communications network based on an asynchronous transfer mode in which communications are held with the use of cells transferred between a node on the upstream side and a node on the downstream side. The method for structuring the network includes a step for preparing a plurality of VPI conversion tables for converting VPIs of the cell input under normal communicating conditions and that of the cell input in the event of a failure and outputting the cell with the VPI converted. The prepared VPI conversion tables are reorganized for each node and the reorganized VPI conversion tables are distributed to all nodes. Then, an alternate route monitoring and switching virtual path is set up in each alternate route and a monitoring cell is periodically transmitted along the alternate route. When a failure occurs, the VPI conversion table is switched over according to the pattern of the failure and the input VPI is converted in accordance with the switched VPI conversion table, and thereby, an alternate virtual path is set up in the relevant alternate route.

An optical bus type communication system comprises a bus type transmission line consisting of an optical fiber, a light source provided at the one end of the bus type transmission line for sending an optical signal having a constant level to the bus type transmission line, a plurality of optical switches mounted on the bus type transmission line, and a plurality of terminal interfaces. Each terminal interface sends data by switching the corresponding optical switch so that the optical signals on the transmission line are modulated with the data.
