Distributed processing management method and distributed processing management apparatus

Abstract

A distributed processing management apparatus analyzes a source file, extracts a reference item name of a reference item that is referenced in processing, and then generates a deletion program describing a process of deleting, from each of plural records, data of a non-reference item having an item name other than the reference item name. Further, the distributed processing management apparatus generates an insertion program describing a process of inserting, in each of the records, dummy data in the position where the data of the non-reference item was located. Then, the distributed processing management apparatus causes plural servers to execute distributed parallel processing based on processing program. When transmitting records, the servers delete data from the records to be transmitted according to the deletion program, before the transmission. When records are received, the servers insert dummy data into the received records according to the insertion program.
