Method for controlling storage of data sets in memory unit.

摘要

In a computer system, there is provided the information (7) representing empty areas generated when data sets (33) are stored in a magnetic disk apparatus (3). From the information, the total capacity (A) of empty areas and the degree of nonuniformity (B/A) in size of empty areas are derived. If the result (83) indicates that a sufficient effect is brought about by effecting recompilation processing of restoring the data sets by packing empty areas, the recompilation processing is carried out (91).
