Publication number: 20100106683Abstract: A streaming server program delivers the content from an original content storage area in a storage apparatus, and a server computer monitors the content delivery status and creates, in a pool storage area, replicated data of the content that satisfies replicated content creation and deletion standards. Upon delivery of the replicated content, an attempt is made to resolve a delivery bottleneck by delivering data from both the original and pool storage areas. Burdens on the administrator are reduced according to the present invention by automatically detecting concentration of accesses or flash crowd and automatically replicating the whole or part of the content, thereby eliminating the need for prediction.Type: ApplicationFiled: January 26, 2009Publication date: April 29, 2010Inventors: Toyohiro NOMOTO, Tadashi TAKEUCHI

Patent number: 7689573Abstract: In a system in which a DB is built in a virtualization environment, a management server obtains DB processing information such as a DB processing execution plan and a degree of processing priority from a DBMS, predicts data to be accessed in the near future and the order of such accesses based on the information, instructs to read into caches of storage devices data to be accessed in the near future based on the prediction results, and reads the data that will be accessed in the nearest future into a cache memory within the management server.Type: GrantFiled: June 19, 2006Date of Patent: March 30, 2010Assignee: Hitachi, Ltd.Inventors: Hideomi Idei, Kazuhiko Mogi, Norifumi Nishikawa, Toyohiro Nomoto

Patent number: 7660832Abstract: A recovery method that uses log takes a long time to recover, and another recovery method that uses backup has the difficulties that if a computer abnormally stops its conversion process due to a failure, the result of the conversion performed up to the time of that abnormal stop couldn't be reflected on the later process for recovery. In a computer system, a system recovery management unit produces backup as the initial status of volume and snapshot taken when the system is operating, by use of a backup restore processing unit of a storage apparatus, and manages the situations of the process by use of a recovery point list/table. When a trouble occurs, it determines a point of recovery from the recovery point list/table, and makes the volume be recovered from the produced backup and the overwriting of meta data in order to keep the data consistency.Type: GrantFiled: December 12, 2006Date of Patent: February 9, 2010Assignee: Hitachi, Ltd.Inventors: Toyohiro Nomoto, Yoshiaki Eguchi

Patent number: 7225196Abstract: A data conversion job used for data conversion is separated into a data conversion server job for executing conversion processing on a data conversion server and a storage job for instructing a copy of a table on a storage device. Then, the storage job is executed to instruct the storage device to copy the table. The data conversion server job is executed only for fields that need to be converted, and thereby data conversion is performed for the copied table. This makes it possible to reduce a load of the data conversion server when converting data of a database, and also to enable a designer of a data conversion job to easily design the data conversion job.Type: GrantFiled: December 5, 2003Date of Patent: May 29, 2007Assignee: Hitachi, Ltd.Inventors: Toyohiro Nomoto, Norifumi Nishikawa, Hideomi Idei, Kazuhiko Mogi

Patent number: 7197554Abstract: A method of generating and linking programs required in a data linkage system to link data among a plurality of computer systems, for example a mainframe and an open system, is provided. In the data linkage system with a means for data transfer via a storage device, a program generation tool is prepared in the open system. The program generation tool reads a data stream definition and generates an intermediate file area securing program and a data linkage program A, both run on the mainframe, and a data linkage program B run on the open system. These programs are linked with one another. The intermediate file area securing program and the data linkage program A are transferred to the mainframe where they are executed.Type: GrantFiled: February 28, 2003Date of Patent: March 27, 2007Assignee: Hitachi, Ltd.Inventors: Yuichi Yagawa, Tomohiro Nakagaki, Toyohiro Nomoto, Hidehiko Ogasawara, Manabu Kitamura

Patent number: 7136862Abstract: There is a strong demand for facilitation of management of storage region for DB data is required in a computer system combining an apparatus having the DBMS and virtualization function and software. In order to realize such requirement, the requirements for system management regarding a newly created DB and the information about the function to be set for the DB data are given to a system management server. The system management server detects a data structure of DB from such information and sends independently instructions to virtualization apparatuses to create virtual volumes or the like to which the data of each data structure is stored separately and set the function to the virtual volume as required. Thereafter, the system management server also issues an instruction to the DBMS to create a DB to store the data of data structure to the corresponding virtual volume.Type: GrantFiled: March 11, 2003Date of Patent: November 14, 2006Assignee: Hitachi, Ltd.Inventors: Kazuhiko Mogi, Hideomi Idei, Norifumi Nishikawa, Toyohiro Nomoto

Publication number: 20060085673Abstract: It is made possible to create automatically and appropriately a secondary volume which is a replication for a volume stored in a storage apparatus. Moreover, with respect to an application which uses the secondary volume, it is also made possible to perform appropriately setting thereof. In accordance with a request from a data conversion batch execution portion 140, a storage management portion 130 creates the secondary volume based on information of an extended volume management table 132 by using a secondary VOL creation portion 110 of a storage apparatus 100 and notifies to a data conversion batch execution program. The data conversion batch execution program determines a volume to be used based on the received information on the secondary volume and optimizes a batch execution process according to the secondary volume by using an execution process control portion 144.Type: ApplicationFiled: January 24, 2005Publication date: April 20, 2006Inventors: Toyohiro Nomoto, Masayuki Yamamoto, Yuichi Taguchi
