Abstract

See full text

Embodiments relate to cache handling in a database system. An aspect includes controlling operations of a set of caches in the database system and determining whether a value of a cache quality parameter of a first cache out of the set of caches meets a cache image creation criterion relating to the first cache. Moreover, an aspect includes selecting at least one cache entry from the first cache, if a value of a related cache entry parameter meets a cache entry criterion, and if the value of the cache quality parameter of the first cache exceeds the predefined value of the cache image creation criterion, and creating a cache image based on the selected at least one cache entry and storing the cache image for further use.
