Abstract: In a distribution system including a plurality of physical machines, when an output file output by first processing performs multistage processing input to second processing, a physical machine which is a deployment destination of a first virtual machine for performing the first processing, a physical machine which is a storage destination of each data block included in the output file, and a physical machine which is a deployment destination of a second virtual machine for performing the second processing are determined based on relationship between the first and second processing.

Abstract: Input data, output data having a plurality of output parameters obtained by analyzing the input data, and a plurality of associations between the input data and the output data are stored. A division condition for dividing an output data distribution in which the output data is plotted for two axes corresponding to two parameters among the plurality of output parameters is extracted, the output data distribution is divided according to the division condition, and output data of the divided output data distribution is derived as first and second output data distribution rules corresponding to the two axes. First and second output data distribution region candidates are calculated by applying the first and second output data distribution rules to new input data, and an output data distribution region of the new input data is estimated by combining the first and second output data distribution region candidates with each other.

Abstract: A federated gateway bridges service definition formatting differences between a first and a second independent enterprise information technology (IT) management domain. A service request is received within the federated gateway from a service consumer application executing within the first independent enterprise IT management domain to a remote service provider application in the second independent enterprise IT management domain. The federated gateway dynamically performs real-time service call translation during transmission of the service request from a local service definition format to a remote service definition format defined respectively within the first and second independent enterprise IT management domains.

Abstract: An automated conversion of service information that includes endpoint addresses of service providers between independent enterprise information technology (IT) management domains is performed using a federated gateway within each of the independent enterprise IT management domains that bridges the independent enterprise IT management domains. Service provider application endpoint translation is dynamically performed, in response to at least one service request from a first independent enterprise IT management domain for at least one remote service provider application in the second independent enterprise IT management domain, using the federated gateway within each of the independent enterprise IT management domains.

Abstract: A search device receives a search request, extracts at least one of an alias or a metadata name from the search request, converts the alias to metadata name by referring to metadata schema management information for managing in an inclusive manner a namespace alias and a metadata name for the retrieval device to identify a metadata schema definition defining the structure of a retrieval-target file that includes metadata, and specifies a field name from the metadata name by referring to schema mapping management information for managing the corresponding relationship between a metadata name of metadata schema definition information and a field name of the retrieval index schema definition.

Abstract: A search server for which data stored in a hierarchical control server utilizing a plurality of storage devices is the object of a search, wherein the search server is designed to update a search index to data while the data exists in an upper-hierarchy storage of the hierarchical control server. Included in a computer system are: a storage unit for storing the usage status of an upper-hierarchy storage area of a hierarchical storage having the upper-hierarchy storage area and a lower-hierarchy storage area; and a determination unit for determining, according to the stored usage status, which process should be given priority between an indexing process for data that is an index-updating candidate among data stored in the hierarchical storage, or a migration process for moving the data to the lower-hierarchy storage area.

Abstract: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

Abstract: In a computer system according to an embodiment of the present invention, a first slave server includes copy management information associating a master file system identifier with an identifier of a slave server including a copy of the master file system identified by the master file system identifier. The first slave server acquires a copy of a part of a master file system. The copy includes a stub-state object (file or directory). The first slave server searches the copy management information for a slave server to be queried regarding information for materializing the stub-state object. If the slave server to be queried includes the information for materialization, the first slave server materializes the stub-state object using the information for materialization acquired from the queried slave server.

Abstract: A second storage unit stores a first piece of data and second pieces of data. Each of first storage units holds configuration information indicating association between the first piece of data and the second pieces of data associated by first computers. Each of the first computers receives a second piece of data and register information of the received second piece of data in the configuration information, instructs a second computer to store the received second piece of data in association with the first piece of data, and identifies a second piece of data to be acquired from the second computer based on the configuration information in acquiring the second piece of data. The second computer, in accordance with instructions from the first computers, stores the second pieces of data in the second storage unit in association with the first piece of data.
