Abstract
Hard page fault patterns of an application program module are analyzed in order to determine the pages that will be retrieved from disk storage during a common hard page fault scenario. Copies of, or references to, the determined pages are stored in a scenario file, along with an index referred to as a page sequence. The scenario file may also include a prologue indicating events that lead to a hard page fault scenario and an epilogue that may indicate subsequent hard page fault scenarios. Execution of the application program module is monitored to detect the occurrence of a hard page fault scenario. When a hard page fault scenario is detected, a corresponding scenario file is fetched from disk storage and the determined pages, or copies thereof, are transferred into RAM. The determined pages, or copies thereof, may be placed on a stand-by list in RAM and later soft-faulted into the working set of the application program upon request by the application program module, thereby avoiding a sequence of hard page faults.
