Abstract:
1. A database processing method for performing processing by which contents of database processing carried out on a computer are forced to a database in a storage unit connected through a network to said computer, comprising the steps of: receiving an access request received from said computer, and judging whether said received access request is a write request or a read request; judging whether contents to be written are log information of a plurality of log records indicating contents of database processing carried out on said computer when said received access request is a write request; and converting position information indicated in said log information, with reference to a conversion table indicating correspondence of logical position information recognized in said database processing on said computer, to physical position information in said storage unit when said contents to be written are said log information, wherein, when said received access request is a write request and said contents to be written are log information, said database processing method further comprises the steps of: chaining said plurality of log records for each transaction to have a plurality of log record chains held in a log management table, deleting, when a COMMIT log is found in log information of said log records, information of a transaction of a log record chain including said COMMIT log from said plurality of log record chains, and updating data in a Logical Unit (LU) in said database area at physical position information in accordance with contents of said log information.
