Assigning shared catalogs to cache structures in a cluster computing system

摘要

An apparatus, system, and method for assigning a cache structure to a catalog. The apparatus includes an identification module configured to identify a catalog for sharing in association with a coupling facility. The coupling facility includes a plurality of cache structures for catalogs of a cluster computing system. The coupling facility is configured to facilitate data sharing among a plurality of host systems of the cluster computing system. The apparatus includes a selection module configured to select a cache structure of the plurality of cache structures for the catalog based on one or more usage status indicators according to an assignment policy. The apparatus includes a storage module configured to store catalog information of the catalog in the cache structure in response to the selection module selecting the cache structure.
