    摘要: A technology for verifying backup data capable of synchronizing timings of checksum calculation and verifying data consistency regardless of the storing position of the data is provided. In a backup system using a data update log, a checksum of data of a backup source and a checksum of backup data are checked, thereby verifying data consistency. Data check log generation means and the like are provided so that the data update log and the data check log are transmitted in order to a secondary site. By this means, the timings of the checksum calculation are synchronized. Further, by providing data area extraction means and the like, the verification of data consistency can be performed regardless of the storing position of the data.

    摘要: The present invention is constituted so as to enable the recovery of a database even when a log comprising a DB update history is not created. When executing a transaction in the logless mode, a logless-start log is created and written to a primary log VOL 55A at the start of this transaction, and this logless-start log is also written to a secondary log VOL 55B. Thereafter, batch processing is carried out for a DB of a primary DB VOL 51A, and while this transaction is being executed, the pair-split state of the DB VOL is cancelled either prior to the start or after the end of the batch processing, and if the difference between the DB VOLs is eliminated subsequent to the end of batch processing, a logless-end log is created and written to the primary log VOL 55A, and this log is also written to the secondary log VOL 55B.

    摘要: The system manages at least a database in multiple database storage units, and the database is duplicated for redundancy. The system maintains the database redundancy for security. The system enables the maintenance and reorganization of the database storage units without interrupting the on-going operations involving the access to the database storage units. The non-stop ongoing database access is available by allocating a pair of a main storage unit and an intermediate storage unit that maintains the substantially identical data. During certain predetermined operations, the main storage unit is being dedicating to the on-going transactions while the intermediate database storage unit is manipulated to contain data that corresponds to a specified time. For example, the content of the intermediate storage is subsequently copied or used to update another database. When the above duplication or incorporation is completed, the intermediate storage unit is updated for the transactions that have taken place during the above operations to be synchronized with the main storage unit.

    摘要: A data processing system is used which is provided with a computer for executing a program, and a storage unit having a cache memory for storing data transmitted as a result of execution of the program and a disk device for storing data stored in the cache memory. The storage unit responds to an input of a request for storing data transmitted from the program to store the transmitted data in the cache memory. Next, the storage unit responds to an input of a request for flashing transmitted from the program to store, in the disk device, the data stored in the cache memory.

    摘要: A data processing apparatus includes a storage device having a replication generation function for replicating a data base to create a replication data base, and stores data and a plurality of log information in transaction processing that uses the data in the storage device, selects a transaction that is performing a data operation without meeting a predetermined condition after synchronization between the data base and the replication data base is released, and performs the data operation cancellation processing to the replication data base by the selected transaction. It also selects a transaction, which meets the predetermined condition and is not performing a data operation to the replication data base, to perform a data operation to the replication data base with the selected transaction. It then becomes possible to reduce the burden for the data processing apparatus during using the replication data base.

    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.

    摘要: A computer is used in a computer system including multiple physical storage areas for storing database data. The database includes component information having a reference item having plural value ranges. The database data is dividable according to value ranges of the reference item. The computer comprises an access frequency obtaining module and a data allocation module. The access frequency obtaining module obtains, for each value range of the reference item in the component information, an estimated access frequency for data of the component information. The data allocation module allocates, based on the obtained estimated access frequency, data of the component information divided according to the value ranges of the reference item to the physical storage areas to be stored.

    摘要: Judgement is made to determine whether or not an access request from a host computer is a write request and whether or not the contents of the write request are log information indicating contents of database processing executed in a buffer by the host computer. When the contents of the write request are the log information, position information indicated in the log information is converted into physical position information in a primary storage system using a conversion table indicating a correspondence between logical position information recognized by the host computer and physical position information in the primary storage system. According to the contents of the log information, data is updated in a database area of the primary storage system represented by the physical position information converted using the conversion table. The access request is sent to a secondary storage system.
