  • Patent number: 9367261
    Abstract: A computer system is achieved which enables a high-speed response to a copy process between computers configuring a KVS (Key Value Store) and ensures data reliability. Disclosed is a computer system in which computers are connected via a network, and a task is executed using a database including storage areas belonging to the computers. The computer system includes a first computer that manages a data set containing pieces of data. The first computer stores replicated data of data contained in data sets managed by other computers. Upon receiving a request for storage (writing and/or overwriting) of new data, the first computer stores the data in memory, replicating the data, transmits the replicated data to the other computers, determines whether the replicated data has been transmitted to the network, and uses the data to execute the task when determining the replicated data was transmitted to the network.

  • Publication number: 20130205193
    Abstract: A web page control method of integrating, by a computer, a plurality of web pages and outputting the plurality of web pages as a single web page, the web page control method including: acquiring, by the computer, integration definition information for defining the plurality of web pages to be integrated into the single web page; extracting, an input/output relationship between components included in the plurality of web pages of the integration definition information; extracting, a component of the web page being an output destination from the extracted input/output relationship; prohibiting, an operation from being performed on the extracted component being the output destination; extracting, all components of the web page being input sources from the extracted input/output relationship; and permitting, the operation to be performed on the component being the output destination when the operation has been completed on all the components of the web page being the input sources.

  • Publication number: 20110035433
    Abstract: In order to solve the problem that the building of a dynamic website requires large amounts of time and cost, this invention provides a method in which, by using a general-purpose script operating with a page transition type website so as to execute asynchronous communication instead of transition between pages through synchronous communication within a website, only a difference between a page acquired as a result of the asynchronous communication and a currently-displayed page is partially updated.

  • Publication number: 20100125548
    Abstract: A support information providing apparatus narrows, when one task item belonging to one task step is to be executed, a plurality of support information candidates down to one support information candidate related to one task item to be executed, in accordance with a task status of a task item by a worker belonging to a task step ordered before one task step of one task item; and provides the narrowed-down support information candidate being related to the task item to be executed.

  • Publication number: 20080183479
    Abstract: A system managing computer communicable with an ESB execution computer has a storage portion for storing deploy information which has service names for designating services constructing a business process and service-deployed ESB execution computers in association with each other. And, it has a processing portion which, based on the deployment information, extracts a combination of plural successive services executable by the ESB execution computers different from the ESB execution computer, defines the extracted combination of the services as a new business process to be deployed on the ESB execution computer, and reconstructs a business process to be deployed on the ESB execution computer as a business process for calling a newly defined business process.

  • Publication number: 20070205313
    Abstract: A self-traveling crusher which enables a worker to easy carry out the operation for removing the reinforcing bars that are entangling, jamming and staying between a crushing device and a discharge conveyer relying on a simple structure without transferring the crushing device to an upper part of the machine body. The self-traveling crusher comprises a hopper into which a material to be crushed will be thrown, a crushing device for crushing the material to be crushed that is thrown in, and a discharge conveyer which is positioned at an end on one side thereof under the crushing device and is extending on the other end side thereof outward of the machine to deliver the crushed material to a predetermined height, wherein the discharge conveyer is mounted on the machine body so as to swing up and down with an end on the side of the crushing device as a center, and is supported at an end on the other side thereof by the machine body via lifting means.
