Abstract: Disclosed is a method for data synchronization in a web-based transmission device management system, in which managing data requiring synchronization between a web server and a client is constructed as a tree data structure, and a change flag for judging a data change is easily set. The web server increases a second event number by a certain degree whenever an event datagram is transmitted to the client, and the client judges whether or not the event datagram is lost by comparing the second event number and a first event number stored by the client whenever an event datagram is transmitted from the web server. If the event datagram is not lost, the client increases the first event number by a certain degree and performs data synchronization using the received event datagram.

Abstract: File locks and file metadata are distributed from a file manager to clients in a data network to permit the clients to share access to file data in data storage. The file manager is permitted to grant a second lock upon the file data without necessarily receiving notification from a client that it has relinquished a first lock on the file data while ensuring that conflicting locks are never granted. The client sets the beginning of a first period of time over which the client may access the file data once the first lock on the file data has been granted by the file manager, and the client sends a lock request to the file manager. The file manager responds by setting the beginning of a second period of time such that the first period of time is certain to have expired once the second period of time has expired, granting the first lock upon the file data to the client, and transmitting a lock grant message to the client.

Abstract: A first database implemented on a remote device such as a handheld computer may be reconciled with a corresponding second database implemented on a host computer during execution of an application program on the handheld device. In addition, the application program may be executed according to program instructions stored in an application program file located in the remote device. The databases may be reconciled by first commencing execution of the application program. Then, during the course of program execution, a synchronization instruction located in said application program file is retrieved. The synchronization instruction is executed by establishing a communications link between the handheld computer and the host computer. Subsequently, any differences between the first database and the second database are reconciled.

Abstract: To allow many users to efficiently use functions of a processing server that performs predetermined processing, via a network and also prevent a time during which an user can use the processing server, from being shortened due to a difference between the times recognized by the user side and processing server side.

Abstract: Primary and secondary servers are coupled together for furnishing a backed-up video streaming function for outputting a series of video content presentations to a user group. The primary server functions as the primary provider of the video files and the secondary server is arranged to operate as a “hot stand-by” to back-up the primary server. In the event the primary server is disabled, the secondary server takes over for the primary server in furnishing video content in accordance with a common playlist. When the secondary server goes down for any reason, the illustrated methodology effectively re-synchronizes the video content and the video stream of the secondary server with that of the primary server such that the secondary server is enabled to resume the back-up function without interruption of the video file streaming process being carried on by the primary server.

Abstract: The present invention provides an address resolution method for use in a multiprocessor system with distributed shared memory. The method allows users to change a memory configuration and a system configuration to increase system operation flexibility and to isolate errors. A cell controller indexes into an address resolution table using the high-order part of a processor-specified address. A write protection flag specifies whether to permit write access from other cells. An attempt to write-access a cell inhibited for write access causes a logical circuit to output an access exception signal.

Abstract: In an Internet system having a plurality of applications, and a plurality of servers for attachment from a plurality of web browsers, a system supports connection oriented applications over a connectionless protocol. At least one of the servers is a master server work station gateway owning a well-known port, and the other servers are slave servers supporting established web browser-to-application state sessions. Dynamic session authentication checking is done by the server to prevent the occurrence of screen spoofing by providing authentication keys which are unique to each session and each panel.

Abstract: A system for time synchronization in a computer cluster is provided. For the system of the present invention a master node sends a SYNC message including a first time stamp to a slave node. The slave node adds a second time stamp and returns the SYNC message to the master node. The master node then adds a third time stamp to the SYNC message. Using the three time stamps, the master node determines if the time clock within the slave node leads or follows the time clock in the master node. The calculation does not depend on the assumption that transmission delays to the slave node are the same as the transmission delays from the node. If the time clocks do not match, the master node sends an INFO message to the slave node informing the slave node of the correct time for clocks within the computer cluster.

Abstract: The network computer (“NC”) stores a replica list in a local storage by an initial downloading of a synchronization list in a server computer as well as resource replicas that are necessary for mobile operation of the NC. When the NC returns to an on-line state to the server, the replication between the resource replicas in the NC and the server resources is performed with reference to the synchronization list and the replica list in the local storage. Even if a synchronous object in the server synchronization list has been modified during the mobile operation of the network computer, the NC can determine the modification in the replication process. This results in a reliable and flexible network computer system.

Abstract: A technique is provided for resynchronizing message traffic in a communication network following network component failure. A failing component, upon restart, retrieves stored control information including a SYNC number and byte sequence number (BSN) from external memory. The SYNC number is then incremented by a predetermined amount to obtain a new SYNC number, with the predetermined amount being sufficient to ensure that the new SYNC number comprises a current SYNC number. Assuming that the failure occurs at a first data processing system in the network, a status request message is sent from the first data processing system to a second data processing system across the logical connection. The status request includes the new SYNC number, and the BSN read from the external memory. The first data processing system waits for a response message to its status request message. The response message contains a BSN of a next piece of data that the second data processing system is expecting.

Abstract: A data storage library subsystem and a method for storing, and maintaining and tracking synchronism between, multiple copies of identifiable data volumes between hosts and a plurality of data storage libraries, and transparent to the hosts. The library controller of each library provides an updatable synchronization token directly associated with each data volume. A plurality of directors are provided, each separate from and coupled to the hosts and each separate from and coupled to each data storage library. Each director responds to ones of separate, partitioned access addresses addressed by the hosts. The responding director supplies each data volume supplied from a host to all of the data storage libraries, and updates each synchronization token directly associated with the supplied data volume. Thus, the directors store duplicate copies of the data volume in the data storage libraries without involvement by the host.

Abstract: During phase one of each protected conversation transaction, one or more messages are inserted. These messages are logged for recoverability. IMS system could crash before phase two of commit. When IMS restarted and eventually reached phase 2, it could vote to abort or commit the conversation. During IMS restart, the retry logic is used to put all protected conversation messages out to central facility with a specification that the first message segment be put on the staging queue using the recovery token as the queue name. If it is an abort request, all messages under the same commit scope identified by the recovery token, will be deleted. If it is a commit request, the first segment of all messages under the same commit scope will be moved to its appropriate ready queue with its actual queue name.

Abstract: Methods of performing client-hosted application sessions in distributed processing systems. The application sessions involve network connected application clients sharing common data and state information. An application client designated as a host client selectively admits other clients into the application session and distributes a common set of application data to each newly admitted application client. The application data includes a unique identifier, assigned by the host client, for each application client in the application session. When a new client is admitted into an application session, application data is transmitted to it in a manner such that the new client receives data that is synchronized with the data possessed by the other application clients in the session. Changes in the application data made by an application client are communicated directly from the application client to other application clients so that each client can maintain a common set of application data.

Abstract: The processing of instructions in a program (task A, . . . ) in one computer (A, . . . ) is interrupted when an instruction (syncpoint x, . . . ) occurs which requests synchronization with a program (task B, . . . ) on another computer (B, . . . ). A set of synchronization data (syncdata x, . . . ) for a program (task B, . . . ) on at least one other computer (B, . . . ) is then fed into a data interface (1, 3, 6) from each program involved, a change is made to a receive state, and the processing of the instructions in a program (task A, . . . ) is interrupted until a set of synchronization data (syncdata y, . . . ) has been received from programs (task B, . . . ) in the other computers (B, . . .

Abstract: Synchronization system and associated methods provide synchronization of an arbitrary number of datasets, including more than two datasets. To achieve this, a reference dataset is used to store a super-set of the latest or most-recent data from all user datasets to provide a repository of information that is available at all times. Therefore, if the user later wishes to synchronize a new user dataset, such as one in a server computer that stores user information, the system already has all the information necessary for synchronizing the new dataset, regardless of whether any of the other datasets are then available. Further, to simplify use, a unified user interface is provided that allows the user to easily determine which of his or her datasets are currently set to be synchronized and allows the user to conveniently alter the current settings to select one, two, or even more than two clients for synchronization.

Abstract: A method for establishing user group accounts in a heterogeneous central server. User groups are established on one type of server that is the central server in the server network which is used to create a corresponding user group account on different types of managed servers in the server network. After establishment of the user group, the server where the initial group was established ensures all group updates, such as change in membership or change in group capabilities are replicated across the server domain. Resources that exist on the network of servers can then have access managed through the usage of user groups. Use and access to the network is more consistent across servers due to ease of management through the use of user groups.

Abstract: A method for creating and updating user accounts at a central server that provides for establishment and synchronization of associated user accounts at a heterogeneous network of managed servers based on the user account information of the central server. This enables the network to consist of a heterogeneous set of servers that are executing with the same operating system or subsystem as the central server, and servers that are executing with a different operating system or subsystem as the central server. The updates to the user accounts on the managed servers are synchronized automatically without systems administrator or user intervention. Updates to the user account are based on central server information and can include password changes, initial resource access or other user account attributes.

The control unit is further configured to buffer the first segment in the primary bus first register until the control unit detects a second segment of the first operation whereupon the control unit is configured to issue the first and second segments of the first operation to the first shared peripheral in consecutive cycles of the shared bus.

Abstract: The present invention provides a method and apparatus for integrating applets running on a client with the application logic for applications running on a server. The mechanism of the present invention provides two significant advantages over the prior art: the synchronization of state, and the recognition of user actions in the browser including the invocation of the appropriate application logic in the server. Instead of using the FORM element available in HTML, individual active applets are available and may be created that obtain user input (e.g. a checkbox, textbox, button, etc.). A hidden applet called the Applet Group Controller is created which handles communication between the applets on the browser and the application logic on the server. The Applet Group Controller maintains an association with each applet that maintains the keys and values of any parameters and variables for the applet.

Abstract: Identifying most recent redundant copies of identifiable data volumes stored in a plurality of data storage libraries which are coupled to a plurality of directors. To update a data volume, an initiating director attempts to set a current token “inconsistent” flag to potentially down level copies of the data volume on each lagging library. Upon failing to receive notification of any successful setting of the current token “inconsistent” flag from any of the lagging libraries, the director forwards the request to the other directors, which attempt to set the current token “inconsistent” flag for the volume at any lagging library from which no notification has been received. Upon all of the other directors responding to the initiating director, and upon the other directors indicating failure to set the “inconsistent” flag at the lagging library, all the directors list the volume and a new token as an entry in a “hot token” list.
