PROBLEM TO BE SOLVED: To increase the number of times of hardware page-out to a disk accompanying a low-speed I/O processing which is frequently utilized, by hierarchizing standby lists. SOLUTION: When the changeover of a page occurs, in the case that there is no vacancy in a working set 110, at the time of an average access interval≤a threshold, the vacancy of a second standby list 150 is checked when there is no vacancy in a first standby list 140, the page is paged out to a page file 130 when there is no vacancy and the page is paged out to the second standby list 150 when there is the vacancy. Also, in the case that there is the vacancy in the first standby list 140, the page is paged out to the first standby list 140. When it is not the average access interval≤the threshold, the vacancy of the second standby list 150 is checked directly and page-out is performed to the second standby list 150. The management is executed by utilizing set/list management data 300. COPYRIGHT: (C)2004,JPO
