Abstract
PURPOSE:To shorten the time required for recall by providing a pool file in which subfiles included in respective files are stored in common and selectively recalling only a subfile as the access object to this pool file. CONSTITUTION:If the resource assignment destination is the pool file, a subfile recall means 7 recalls this subfile from a migration file 3 to a pool file 4. When the subfile as the access object is recalled to the pool file 4, information related to this subfile is registered in a pool file management file 5. The subfile recalled to the pool file 4 makes access by the normal file access method. When the access is terminated, a subfile migration means a migrates this subfile from the pool file 4.
