    摘要: Provided is a storage system in which a transaction of a database is quiesced, a pair of a first volume and a second volume is split so as to make settings to allow an access to be made only to the database in the first volume, the transaction is then released from the quiescent state, a sparse space is specified in the database stored in the second volume, only the specified sparse space in the second volume is partially reorganized, and the contents of the partially reorganized second volume are copied to the first volume such that the first volume and the second volume are resynchronized with each other to form the pair again.

    摘要: A data storage position management main program collects volume physical storage position management information and physical storage apparatus operation information from a storage apparatus, and stores them as storage apparatus arrangement information and storage apparatus operation information. The program also collects necessary information from schema information in a DBMS, stores it as DBMS schema information, collects mapping information in a host and virtual volume information in a virtual volume switch, stores them as data storage position management information, acquires execution history information from the host, and stores it as a DBMS execution history information. The program determines a data relocation plan having a better performance characteristic on the basis of the above information.

    摘要: To reduce operational and management costs during normal operations while recovering a database without loss and maintaining on-line performance on a site. A first system includes a primary storage system (103) that stores a DB (107) and a main computer (100) that executes a primary DBMS (101), which provides a DB. A second system includes a secondary (113) that receives from the primary storage system (103) a copy of a log, which shows update differences of the DB (107), and stores a secondary DBMS (117), and a subset (500) that recovers the secondary DB (117) according to the log that is copied from the primary storage system (103). When a failure occurs in the first system, the first system is switched to the second system. A second computer (110) that executes a second DBMS (111) is added to the second system, and the secondary DB (117) that is recovered or is being recovered in the subset (500) is taken over to the second computer (110).

    摘要: A storage apparatus acquires static constituent information of a database management system (DBMS) through a network by using a DBMS information acquisition/communication program, DBMS information communication portion, and host information setting program, and stores them as DBMS data information in its memory. The physical storage position managing/optimizing execution portion within a control program of the storage apparatus makes data allocation and cache control that consider the characteristics of the data base management system by using DBMS data information, thereby improving the data access performance of the storage apparatus.
