20140040331 | COMPUTER SYSTEM, FILE MANAGEMENT METHOD AND METADATA SERVER - A computer system, comprising: a file server; a metadata server; and a business server, the metadata server being coupled to a storage apparatus for providing a save area for storing at least one file that is removed from the file server, the metadata server storing a metadata repository for managing metadata of a file and the files stored in the save area, the metadata server being configured to: store a file as a saved file in the save area, in a case of detecting that the file stored in the file server is to be removed; and store information indicating a location of the file in the file server and information indicating the location of the saved file in the save area in association with each other in the metadata repository. | 02-06-2014 |
20150106363 | COMPUTER SYSTEM, DATA MANAGEMENT METHOD, AND RECORDING MEDIUM STORING PROGRAM - When plural processing programs for generating post-processing data which is a source of services to be provided are present, a relationship between post-processing data and a data group which is a source of the post-processing data is managed. The processing units acquire pre-processing data, execute given processing, and generate post-processing data as a result of the processing. At an opportunity to acquire the pre-processing data, a process ID indicative of ordering of the acquisition, and not updated before and after the given processing is allocated to acquired pre-processing data. The generated post-processing data is stored, and in extracting the post-processing data satisfying the given data search condition, the post-processing data having a process ID equal to or before the process ID that is latest in the post-processing data and oldest among the respective processing units is extracted from the post-processing data that satisfies the data search condition. | 04-16-2015 |
20150213043 | RETRIEVAL DEVICE, METHOD FOR CONTROLLING RETRIEVAL DEVICE, AND RECORDING MEDIUM - 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. | 07-30-2015 |
20150227599 | MANAGEMENT DEVICE, MANAGEMENT METHOD, AND RECORDING MEDIUM FOR STORING PROGRAM - Replication is performed with consideration of data integrity between each subsystem when replication of a computer system that uses data by processing data and transferring the data to a next subsystem is performed. A management device that manages a computer system including a second subsystem which performs a predetermined process for data processed by a first subsystem and generates data which is a target of data processing by a third subsystem obtains process history information in which information indicating an input source and an output destination subsystem of data that is processed by each subsystem is included and trigger information in which information indicating a trigger for data input and output of the input source and the output destination subsystems is included, thereafter detects a dependence relationship of data input and output between each subsystem from the process history information, calculates a replication trigger for subsystems subsequent to a next subsystem for each of the subsystems subsequent to the next subsystem that is next to a subsystem of which an input source is not present with reference to the trigger information, and generates, in response to the replication trigger, a replication of each subsystem in another different computer system. | 08-13-2015 |
20150309929 | COMPUTER SYSTEM, DATA MANAGEMENT METHOD, AND RECORDING MEDIUM FOR STORING PROGRAM - 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. | 10-29-2015 |
20150324436 | DATA PROCESSING SYSTEM AND DATA PROCESSING METHOD - A data processing system holds metadata extraction dictionary information defining a condition for extracting metadata from a plurality of kinds of data and relevance dictionary information defining a condition for associating the metadata extracted from the plurality of kinds of data, extracts the metadata from the plurality of kinds of data on the basis of the metadata extraction dictionary information, extracts metadata from inputted data, associates the metadata extracted from the inputted data with the metadata extracted from the plurality of kinds of data on the basis of the relevance dictionary information, and outputs information indicating a relation of any combination of the plurality of kinds of data, the inputted data, and the metadata extracted from the plurality of kinds of data and the inputted data on the basis of a result of the association. | 11-12-2015 |
20150331916 | COMPUTER, DATA ACCESS MANAGEMENT METHOD AND RECORDING MEDIUM - A computer system including a shared file server manages the access to file data for performing access to the file data accurately and efficiently. This computer includes a plurality of first name spaces to which is assigned an access path to data stored in a storage area, and a name space to which is assigned a path corresponding to the access path and which is different from the first name spaces. When the access paths generated in different first name spaces are the same, the corresponding paths which correspond to the same access paths are changed into mutually different paths. Moreover, by assigning a path corresponding to the data to be analyzed, it is possible to efficiently access the requested data among a large amount of data. In addition, the sorting of the corresponding paths is changed according to the load of the computer storing the data. | 11-19-2015 |
20150339359 | COMPUTER SYSTEM, METADATA MANAGEMENT METHOD, AND RECORDING MEDIUM - An object of the invention is to manage correspondence between data having different schemas stored in process servers, data warehouses, or the like in the computer system having a complicated modularity configuration in an integrated manner. The computer system includes a storage portion that maintains schema correspondence information indicating correspondence of metadata described in different schema formats; a storage device that stores metadata in a second schema format different from a first schema format, which is transformed based on the schema correspondence information in a manner of being associated with corresponding actual data and a unified ID; an index portion that acquires the metadata and the unified ID in the second schema format from the storage device and maintains the metadata index transformed in a third schema format different from the first and second schema formats based on the schema correspondence information; and an update managing portion that specifies the unified ID of the metadata to be an update target by using the schema correspondence information in response to an update request of the metadata having a predetermined schema format. | 11-26-2015 |
