摘要： A server to be changed is added to a destination unit in terms of configuration. The server to be changed is started to restore the database in the database storage region to which the server has access and to restore the transaction for the process that was executed when the server failed. The destination of the failed server (a system destination unit) when failure occurs is determined to stabilize the throughput of the entire system after the switchover of the system in the event of failure. The destination server is determined according to an instruction given in advance by the user. The database management system statistically determines the destination server in accordance with a policy designated by the user. Alternatively, the database management system dynamically determines the destination server according to the policy designated by the user when failure occurs.

摘要： In a database management system using a shared-nothing architecture and adopting a system takeover in a DB storage area unit, correspondence information is provided which indicates a relation between a DB storage area and a DB processing server in charge of an access to the DB storage area, when a takeover occurs to some DB storage area, the correspondence information is changed in such a manner that an access process to the DB storage area is made in charge of another running DB processing server, and when some DB storage area is accessed in response to an inquiry request from a user, a DB processing server as an access request destination is determined by referring to the correspondence information.

摘要： The technology for changing the nodes in an information retrieving system using a computer. When information items are registered by allocating to n nodes, steps are used to extract index information as a set of pairs of index keys of information items and addresses of information items, divide the index information into m (m>n) buckets and produce a partial inverted file to be closed within each of the buckets. Here, m and n are respectively integers of 1 (one) or above. When the allocation of the search-targeted ranges to the nodes is altered, the allocation to the buckets to each of the nodes is changed, and the partial inverted file of each bucket and the inverted file of the existing indexes are merged to produce new indexes, so that the indexes can be produced and updated with high speed.

摘要： The present invention provides a system switching function for database management systems which requires no standby resources idling during normal operation. One aspect of the invention is directed to a method for processing databases in a system which includes a plurality of storage areas each storing a database and a plurality of computers each having a database management program running thereon which manages one of the plurality of storage areas. Each storage area is associated with only the computer managing the storage area. The method comprises, when a failure has occurred in one of the plurality of computers as a failed computer, obtaining preset substitution information indicating that the storage area managed by the database management program running on the failed computer is to be managed by the database management program running on another one of the plurality of computers as a substitute computer; and, based on the substitution information, changing association of the storage area with the failed computer to the substitute computer. The storage area is to be managed by the database management program running on the substitute computer.
