PURPOSE:To improve a retrieving processing efficiency by constituting a computer system distribution storehouse with a disfile of respective processings of retrieving a space bucket area, setting a space bucket, setting a bucket division pattern and setting using bucket area. CONSTITUTION:A bucket bit pattern 30 is constituted of a division bit pattern 31 of two bits and a using area bit pattern 32 of 4 bits and stored in a bucket bit map file to control the using state of the bucket. This file is used to execute a space bucket retrieval processing 1, a space bucket area setting 2, a division bucket pattern setting 3 and using bucket area setting 4. The space area is retrieved, the using bucket area is set, the using bucket area is returned to the space bucket area and the division pattern is set. According to this constitution, the efficiency for retrieving the bucket can be improved. |
