Abstract
A computational device receives an indication of minimum retention times in a cache for a plurality of tracks for applications. In response to determining that a first type of application has not specified a maximum percentage of cache for allocation to the first type of application, the maximum percentage of cache for allocation to the first type of application is set to a default value. In response to determining that a second type of application has not specified a maximum percentage of cache for allocation to the second type of application, an entirety of the cache or a percentage of the cache that is greater than the default value is allocated for the second type of application. A least recently used based replacement of tracks is performed in the cache while attempting to satisfy the minimum retention times and the maximum percentage of cache that are allocated.
