Abstract
A method and computer program product are provided for paging control using a reference structure in a computer system. The reference structure is scanned to identify a next selected entry for an IO range building routine. The next selected entry is compared with a set hardlimit value. Responsive to the next selected entry being greater than the hardlimit value, the IO range building routine is exited. A shortlimit value is identified. The next selected entry is compared with the identified shortlimit value. Responsive to the next selected entry being greater than the identified shortlimit value, the IO range building routine is exited. A first array is used for storing entry IDs for selected entries found from scanning the reference structure and a second array is used for tracking blocks of storage used for the selected entries.
