<P>PROBLEM TO BE SOLVED: To suppress a decrease in reliability of access to a database. Ž<P>SOLUTION: When a client access request showing a request of access to a database from the client is received, a first database access request is issued to the database, an access to the database corresponding to the client access request is performed by making a second database access request after a response to the first database access request is received, and an accessed period of time from an access start time of day when the client access request is received to a time of day of prescribed processing timing between an access start time of day and a time of day of timing with which the second database access request is made is counted. When it is detected that the accessed period of time is equal to a reference time or longer, the execution of the second database access request is canceled. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
