20100008366 | MESSAGE TRANSFER PROGRAM, MESSAGE TRANSFER METHOD, AND MESSAGE TRANSFER SYSTEM - A transmitting apparatus extracts header information from messages stored in a queue to generate a digest by collecting the extracted header information. The transmitting apparatus transmits the digest to receiving apparatuses specified by address information stored in a address information storage unit. Upon receiving a message obtaining request specifying any header information contained in the digest from any of receiving apparatuses, the transmitting apparatus reads out a message corresponding to the specified header information from the queue to transmit the message to the receiving apparatus that transmitted the message obtaining request. The receiving apparatus stores therein receiving conditions that specifies a message to be received from the transmitting apparatus and searches the digest received from the transmitting apparatus for the header information that satisfies the receiving conditions. The receiving apparatus transmits a message obtaining request that contains the retrieved header information that satisfies the receiving conditions to the transmitting apparatus. | 01-14-2010 |
20110296233 | TASK RELAY SYSTEM, APPARATUS, AND RECORDING MEDIUM - A computer which takes over a task managed by a server apparatus from another computer which occupies the task, the computer including, a processor to detect an error of the other computer, to transmit, when an error of the another computer is detected, a task relaying request for taking over the task to the server apparatus, and to allow when a permission of the takeover of the task is received from the server apparatus processes of application programs in standby states in the computer to occupy the task. | 12-01-2011 |
20120191645 | INFORMATION PROCESSING APPARATUS AND DATABASE SYSTEM - An information processing apparatus includes an execution response unit that executes an operation command and sends results of the execution to a process execution apparatus, a first result update unit that, upon receiving a determination command when the information processing apparatus is operating normally, updates the information processing apparatus with the results of the execution sent by the execution response unit and that transmits the results of the execution to copy apparatuses, a second result update unit that, upon receiving the determination command when operation of the information processing apparatus is abnormal, transmits an abnormality notification to the copy apparatuses, and a determination transmission unit that, upon being notified of the update using the results of the execution from the copy apparatuses that have received the results of the execution transmitted from the first result update unit, notifies the process execution apparatus of the determination of the operation command. | 07-26-2012 |
20120278429 | CLUSTER SYSTEM, SYNCHRONIZATION CONTROLLING METHOD, SERVER, AND SYNCHRONIZATION CONTROLLING PROGRAM - A cluster system includes an active server and an additional server, and each of the servers includes a database (DB) storing therein client data, information indicating the location of the client data, and information indicating a record status as a record. The active server transmits a record included in the DB as first information as well as type information indicating the first information to the additional server, and when the record is updated, transmits the record thus updated as second information as well as type information indicating the second information to the additional server. The additional server receives the first information or the second information from the active server. The additional server then generates a record for the information thus received in the DB depending on the received type information and the status of the record stored in the DB and identified by the received information. | 11-01-2012 |
20130205017 | COMPUTER FAILURE MONITORING METHOD AND DEVICE - Disclosed is a non-transitory computer-readable medium storing a program that causes a client device to execute a sequence of processing. The sequence of processing includes generating, by a processor, a processing request message by attaching status information including information indicating a status of a first server device stored in a storage part to a processing request addressed to the first server device, transmitting the generated processing request message to the first server device and a second server device monitoring the first server device, and receiving from the first server device a new status information of the first server device. | 08-08-2013 |
20130205162 | REDUNDANT COMPUTER CONTROL METHOD AND DEVICE - Disclosed is a non-transitory computer-readable medium storing a program, which causes a computer to execute a sequence of processing. The sequence of processing includes receiving status information by a second server device from a client device, the status information being collected by the client device, and including a status of a first server device and statuses of one or more standby servers configured to operate when the first server device fails, and causing the second server device to operate, when the status information indicates a predetermined first status, as at least one of the first server device and the one or more standby servers in a failure status. | 08-08-2013 |
