Abstract
In a data processing method of a coupling facility connected to a plurality of computer or processing nodes which access files of different formats to share files therebetween, it is possible to minimize overhead of the format conversion between files. Stored in the coupling facility is a channel information table including information of formats of files to be accessed by computers. A processing node updates a file and sends an update file resultant from the update to the coupling facility. On receiving the update file, the coupling facility refers to the table to convert the file into files of the formats related to the processing nodes sharing the file and stores the converted files in a file cache. Receiving a request from a processing node for latest data of the shared file, the coupling facility selects one of the converted update files related to the requesting node and sends the selected file thereto.
