ABSTRACT:
A device management system in a computer system comprising a unit for measuring a load condition of a device such as a real memory to be managed. A unit is also included for determining a management period such as an update period of a real page in a real memory in accordance with the load condition, such as an unreference interval count (UIC) of the real page. The management period is determined such that, the larger the value of the load condition is, the shorter the management period, or the larger the UIC of the real is, the longer the update period. Since the management period is changed in accordance with the load condition of the device to be managed, management of devices is thereby accomplished with a lesser Central Processing Unit (CPU) time. Additionally, the device management system updates a time value for which a real page has not been referenced.
