ABSTRACT:
A data processing system, having virtual addressing capability, has a real storage manager to associate virtual storage locations with real storage by accessing page tables to determine the locations of "backed" virtual storage pages in central, expanded, or auxiliary storage. The real storage manager accepts requests to copy ranges of virtual storage from one virtual storage range to another, and, in so doing, uses the page tables to effectively perform the copying by reassigning backed pages from the source range to the target range. Having been reassigned to the target range, the backed pages are artificially aged by increasing the unreferenced interval count (UIC), so that the backed pages in the target range will be likely candidates for page stealing.
