摘要： PROBLEM TO BE SOLVED: To solve the conventional problem of inefficient use of a physical disk, because unnecessary physical disk allocation to a storage pool is required in advance when the capacity of an unused memory area in the storage pool becomes short. SOLUTION: A computer system includes a business computer, a storage system connected to the business computer, and a management system including one or more computers connected to the business computer and the storage system. The management system monitors the capacity of the storage pool, and transmits an allocation request to the storage system when the storage pool capacity is a preset threshold or smaller. On receiving the allocation request, the storage system allocates a first logical memory area to the storage pool, according to the information included in the allocation request. The management system displays information to confirm whether the tentatively allocated first logical memory area is to be assigned to the storage pool. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To maintain consistency of a duplicate data base as continuing a transaction processing and to access a physical duplicate data base without changing an application program to access a data base at a duplicating origin when the physical duplicate data base is created by cutting off one of multiply written or duplicated data base areas on an external storage device. SOLUTION: When one of the multiply written or duplicated data base areas is cut off on the external storage device, a data base management system writes data at a state that the consistency is maintained in the external storage device and provides a means capable of controlling timing to cut off the duplicated data base areas. In addition, a new piece of physical definition information to be required for access to the duplicated data base is dynamically added based on the physical definition information of a data base at a duplicating origin and provides a means capable of selecting whether the data base on the duplicating origin is accessed or a data base at a duplicating destination is accessed is provided.

摘要： PROBLEM TO BE SOLVED: To reduce a data quantity of a log file gathered for recovering a database.
SOLUTION: When updating the database, a pre-update log making part 112 of a log acquiring part 109 acquires pre-update data from a database management control part 107, and outputs this pre-update data to the log file. A post-update log making part 114 acquires this pre-update data and post-update data. A difference information making part 113 makes difference data of the post-update data to the pre-update data. The post-update log making part 114 outputs the difference data to the log file when the size of the difference data is smaller than the size of the post-update data, and outputs the post-update data to the log file in a nonsuch case.

摘要： PROBLEM TO BE SOLVED: To keep consistency of a replicated database while continuing transaction processing when one of multi-written or replicated database areas in an external storage unit is separated to create a physical replicated database, and to enable the physical replicated database to be accessed without changing an application program accessing a replication source database. SOLUTION: When one of database areas multi-written or replicated in external storage units 108 to 109 is separated, a database management system 101 writes data in a consistent state into the external storage units 108 to 110 and controls timing of separating the replicated database area. Furthermore, new physical definition information necessary to access the replicated database is dynamically added on the basis of physical definition information of the replication source database and it is selected whether to access the replication source database or access the replicated database.

摘要： PROBLEM TO BE SOLVED: To reflect an intention of a host device to data migration executed by a storage device. SOLUTION: A host manager preliminarily registers a host-side data migration policy to an operation management server 30. When data migration by the storage device 20 is started, the management server 30 compares a storage-side data migration policy with the host-side data migration policy, and permits the execution of the data migration by the storage device 20 when both the policies are matched. When both the policies are mismatched, the management server 30 prohibits the execution of the data migration by the storage device 20. The management server 30 counts the frequency of the mismatching of both the policies, and generates and transmits a report for drawing attentions of the host manager and a storage manager to each manager.
