摘要： A disaster recovery system and a method therefor, having: a function for receiving write requests from a host computer to write log information indicating the contents of a database process executed for a database buffer on a main site, database data updated on the database buffer and status information indicating the position of log information used for disaster recovery; a function for transferring the received write request for log information to a recovery site by a synchronous remote copy process; and a function for transferring the received write request for database data to the recovery site by an asynchronous remote copy process. While remote copy can be executed at a long distance without data loss, the deterioration of the performance of a database process on a main site can be suppressed.

摘要： A storage system carries out database reorganization processing. In a method of reorganizing, a database which is stored in a disk drive of a storage device is reorganized. The disk drive contains a first volume where the database is stored and a second volume paired with the first volume to store a copy of the database. The reorganization method includes the steps of: making transactions from the host computer into a quiescent state; splitting the paired first volume and second volume so as to only allow the database in the first volume to be accessed; releasing the quiescent state of the transactions; reorganizing the second volume; and copying data in the second volume to the first volume to resynchronize and pair the first volume and the second volume with each other.

摘要： A management device stores configuration history information indicating a history of system configuration changes, from this information, specifies a system configuration of a recovery time, which is a certain point in time in the past, specifies a system configuration of the current time, and compares the system configuration of the recovery time with the system configuration of the current time, and based on the results of this comparison, specifies whether or not there is a system configuration part in the system configuration of the current time for which, if data of the recovery time is recovered, a setting change is required in order to access this recovered data. When this system configuration part is specified, the management device constructs a system configuration for enabling a data utilization unit to access the recovered data by issuing an indication related to a required setting change to an element capable of carrying out the setting change for this system configuration part.

摘要： If relocation of a table with a high reference frequency is made possible, the database management method and system are arranged to improve performance according to the number of increased nodes and accumulate a reference frequency of each external storage unit allocated to each database management node. A data storage area for storing the table with a high reference frequency, located in the external storage unit, is specified as a shared data area to be referenced by plural nodes. The system is controlled to cause the nodes to refer to the shared table stored in the shared data area on any timing in parallel. This prevents load from being concentrated onto the node allocated to the data area.

摘要： The invention relates to backup processing for performing backup of data used in an information processing device having a storage unit. When data has been updated, updated bit information indicating that the data has been updated is stored in an update bitmap management table stored in the storage unit. When the number of updated bit information in the update bitmap management table has reached a differential backup reference value for estimating differential backup time, the backup of data corresponding to the updated information is commanded. When the command for the backup is received, the updated bit information stored in the update bitmap management table in the storage unit is read out. Then, the backup of the data corresponding to the updated bit information is obtained.
