Abstract
A memory management system and method that determines which page or pages in cache memory are likely to be accessed again in the near future by another transaction and designates those pages for recycling so that the pages are maintained in the cache memory for a longer period of time. That is, pages designated for recycling are maintained in the cache, while pages that are not are first replaced. According to the present application, pages in the cache that are likely to be accessed in the near future are those that are accessed by two or more different transactions during their normal residence in the cache.
