Patent number: 6665716Abstract: A delay factor in a processing in a job system in which an ordered series of jobs are executed in computers assigned to respective jobs, is efficiently detected, and the delay factor is analyzed in detail by associating it with load information of the computers and a network. An administrative manager computer 201 collects a history of executing a job from each job executing computer 202, and refers to a history of each job, one by one from a job executed later to a job executed earlier, until no delay is detected in a job, for judging a cause of delay in each job. Further, with respect to a job in which delay is detected, load statuses of the other jobs or applications in the computer in which said job is in execution are compared with said job and displayed.Type: GrantFiled: August 31, 1999Date of Patent: December 16, 2003Assignee: Hitachi, Ltd.Inventors: Toshiaki Hirata, Yasuo Takenaka, Eiji Matsumura, Shigeru Miyake, Satoshi Miyazaki, Akihiro Urano

Publication number: 20030197722Abstract: A method, apparatus and computer program for displaying partial information related to network equipment connected to a network being managed by a network management system. The partial information is required for network management to be conducted from the network equipment. A managed terminal is included in each network equipment. The network management system collects management information from each network equipment and stores management information therein. When conducting network management, the managed terminal sends a request for network management. The network management system in response transfers a program for managing the network to the managed terminal. The transferred program informs the network management system of the identification of the managed terminal. Partial information is transferred to the managed terminal based on the identification. The managed terminal then displays the transferred partial information.Type: ApplicationFiled: June 11, 2003Publication date: October 23, 2003Inventors: Kiminori Sugauchi, Tomohiro Morisada, Toshiaki Hirata, Satoshi Miyazaki, Toshio Sato

Patent number: 6275856Abstract: When a computer as a logical connection destination which detected a search objective user issues a search request to first one of computers which established logical connections associated with the search objective user, the first computer selects users who used my computer in a use time of the search objective user, and executes the search request over the computers which established the logical connections associated with the selected users. The same search request is sequentially carried out over m candidates of the logical connection originator computer of my computer down to an m-th computer. Search results (a computer identifier of my computer and user identifiers of the selected users) obtained by the m computers are collected in the respective computers and returned to the logical connection destination computer in an order opposite to the search request order.Type: GrantFiled: February 22, 2000Date of Patent: August 14, 2001Assignees: Hitachi, Ltd., Hitachi Information Networks, Ltd.Inventors: Toshiaki Hirata, Akihiro Urano, Shuji Fujino, Mitsugu Yamada, Hidetomo Nakano, Shinji Morita, Satoshi Miyazaki

Patent number: 6170010Abstract: In a computer system to which a plurality of computers are connected, a managing computer manages operations performed in the respective computers in an integrated manner, or manages the operations in relation to the computers themselves. As a result, problems occurring in the processes can be easily solved, and furthermore a load on a network is reduced. The managing computer manages a series of operations in an integrated manner in which when an operation is executed by each of the plurality of computers, or by the respective computers in combination with each other, the managing computer performs an operation designated when a specific event happens to occur on a computer. The managing computer displays each of the operations executed on the computers by a symbol; displays an execution sequence of the operations by a link with a direction among symbols; and further displays an execution condition of the computer by a color of a symbol.Type: GrantFiled: November 9, 1998Date of Patent: January 2, 2001Assignee: Hitachi, Ltd.Inventors: Toshiaki Hirata, Akihiro Urano, Shuji Fujino, Eiji Matsumura
