THRASHING REDUCTION IN DEMAND ACCESSING OF A DATA BASE THROUGH AN LRU PAGING BUFFER POOL

摘要

A CPU implementable method for minimizing thrashing among concurrent processes demand page accessing a data base through an LRU page organized buffer pool. There is ascertained the set of pages over which there is looping access behavior for the prospectively executing concurrent processes. This parameter, as determined for each task, is passed to the storage accessing component which partitions the buffer into LRU stacks and dynamically adjusts the stack to this predicted parameter size.
