Abstract
A host system includes a multicache system configured within a host system's memory which has a plurality of local and central cache systems used for storing information being utilized by a plurality of processes running on the system. The central cache system includes an obsolete code management (OCM) component that operates to detect and remove obsolete entries stored within the central cache system. The OCM component operates to remove obsolete code from all the caches when events cause such obsolescence, e.g., data definition language (DDL) statements are executed. In certain situations, by being able to perform such operations during DDL statement processing, the OCM component further enhances overall system operation.
