Abstract
Provided are a computer program product, system, and method for adjusting active cache size based on cache usage. An active cache in at least one memory device caches tracks in a storage during computer system operations. An inactive cache in the at least one memory device is not available to cache tracks in the storage during the computer system operations. During caching operations in the active cache, information is gathered on cache hits to the active cache and cache hits that would occur if the inactive cache was available to cache data during the computer system operations. The gathered information is used to determine whether to configure a portion of the inactive cache as part of the active cache for use during the computer system operations.
