摘要： Database synchronization processing is completed within a reasonable time, using narrow-band network that connects a primary site to a secondary site, to reduce the running cost of a system. A primary DBMS has a transaction executing unit for reading a primary DB of a primary storage system to update data as requested in an update request, and a write unit for writing the updated data in the primary storage system. The primary storage system includes an unnecessary information removing unit for overwriting an unused area in the written data successively with one of a preset character and a preset value. The primary storage system is connected, via a network, to a second storage system which stores a copy of the primary DB. The primary storage system is connected to the network via a network device which has a data compression unit for compressing a succession of the same value.

摘要： Database processing including processing for a shared table is efficiently executed. Processing for a database including a shared table which can be referred to by a plurality of database processing devices is managed. Table information indicating database processing devices allocated according to an attribute of a table in a database and a processing type is referred to via a storage. According to whether or not a processing request for the database includes processing for a shared table, a database processing device to execute the processing request is selected. The database processing request is issued to the selected database processing. According to the database processing request, the database processing device accesses the database.

摘要： Database synchronization processing is completed within a reasonable length of time while employing a narrow-band network as a network that connects a primary site to a secondary site, to thereby reduce the running cost of a system. A primary DBMS (101) has a transaction executing unit (104) for reading a primary DB (119) of a primary storage system (110) to update data as requested in an update request, and a write unit (106) for writing the updated data in the primary storage system (110). The primary storage system (110) includes an unnecessary information removing unit (1400) for overwriting an unused area in the written data successively with one of a preset character and a preset value. The primary storage system (110) is connected, via a network (320), to a second storage system (120) which stores a copy of the primary DB (119). The primary storage system (110) is connected to the network (320) via a network device (140) which has a data compression unit for compressing a succession of the same value.

摘要： The data processing system controls, from the database management system on a host computer, the storage device subsystem which stores log data supplied from the database management system; allocates on a disk cache in the storage device subsystem in advance a log-dedicated buffer area of a size equal to that of the log data output between checkpoints; writes log data into the buffer area; and, in the event of a host computer failure, reads out the log data from the disk cache without making access to a disk device. Since the log information required for the recovery of the data processing device is cached on the storage device side, the time it takes to read the necessary log information can be shortened, which in turn reduces the system recovery time.

摘要： A disaster recovery technology capable of achieving the high-speed FO and correctly reading the logs even if the unit of logs written in the main site is large is provided. In the disaster recovery system comprising a main site and a sub-site, when the writing in units of a log block consisting of a plurality of log records is performed in the main site and the logs are applied in the sub-site, the log blocks are read from the sub-storage to verify the consistency, and it is determined whether the reading process conflicts with the writing process through the remote copy operation when reading the logs. Then, only the log blocks in which the reading process does not conflict with the writing process as a result of the determination are applied to the database. Thereby, the logs are applied in the sub-site independently to recover the database.

摘要： A database system for storing table data as divided in a plurality of storages has a processing request acceptance section and an execution section which, at the time of rebalancing already stored data in response to addition of a storage, can execute inquiry operations concurrently. The system determines data to be moved from existing storages to the additional storage. When search, update and delete processing requests are issued during execution of the rebalance operation of copying the data to the additional storage and deleting the original data, both the DBMS acceptance section and DBMS executor section execute the operation corresponding to the requests. When an insert processing request is issued, the system determines a data insert destination on the basis of contents of a step of dividing the data from the existing storages to the additional storage.

摘要： It is an object of the present invention to use the resources of various sites in an effective manner. The first site has a first DB access part in use. The second site has a second DB access part in use in addition to a first DB access part for standby corresponding to the first DB access part in use. The second DB access part in use writes data into a second storage device that is assigned to the second DB access part itself. The inter-site monitoring server monitors the first DB access part in use and the second DB access part, and in cases where it is detected that the first DB access part in use has gone down, the inter-site monitoring server switches the first DB access part for standby to the DB access part in use.
