PURPOSE:To shorten the response time even in the case of the variance of a picture image used by a transaction processing program by dynamically changing the picture image to be made resident in a memory based on the frequency in use request to each picture image per unit time. CONSTITUTION:The frequency in use request to each picture image per unit time is managed by a picture image management table 15. At the time of picture image residence processing, a picture image residence means 5 updates a residence flag based on the frequency in use request to each picture image, which is managed in the picture image management table 15, per unit time and performs the picture image residence processing based on the updated residence flag. Thus, the picture image to be made resident is dynamically changed even in the case of the variance of the picture image which the transaction processing program uses. Thus, the response time is shortened. |
