Abstract

An extended storage is temporarily used for the dedicated use by a batch process to eliminate the contention of resources between an online process and the batch process and attain a high speed batch process while the online process is executed without affecting the online process. The online process is executed by inputting data from a file to a main storage, and the batch process updates the data on the extended storage in parallel with the online process. Since the accessing device for the online process and the batch process are different, there is no contention of resources. When the batch process is completed, the updated data is reloaded from the extended storage to the file. During the reloading of the updated data, the online process inputs the data from the extended storage. The extended storage is shared by the reloading of the updated data and the online process, but the contention of resources does not occur because both are input processes and the extended storage is a storage device which does not includes a mechanical movement unlike a magnetic disk drive.
