Abstract
Systems, methods and computer program products are disclosed for managing a database cache. In one embodiment, access to a data object stored in a database is monitored. A memory residency priority for the data object is determined, based on the access patterns. Further, an access plan is determined for a query, based on the memory residency priority. Access to the data object is also monitored when the access plan is executed, thereby providing a feedback loop between determining memory residency priorities and determining query access plans.
