CENTRAL STORAGE MANAGEMENT WITH MVS/ESA Donald R. Deese Beginning with MVS/ESA SP3.1.3, IBM redesigned the logical swapping algorithms, integrated the page stealing process with logical swapping, and revised the algorithms controlling processor storage (central storage and expanded storage). This logic has been enhanced with MVS/ESA SP4.2 and SP4.3. A major goal of the changed logic is to take advantage of increasingly large amounts of processor storage and to minimize page and swap I/O operations. This paper describes the concepts and algorithms used to manage central storage with MVS/ESA and highlights major changes between MVS/XA and MVS/ESA. Download paper (pdf format).
