<P>PROBLEM TO BE SOLVED: To reduce processing to be executed by a business application when a trouble occurs in a backend side. <P>SOLUTION: The data processing system comprises: a front node 100 that receives a processing request from a business AP (Application) 300; and a back node 200 that receives a processing request from the front node 100 and executes processing for the processing request. The back node 200 includes a response generation unit 203 that, when a trouble occurs during performing the processing for the processing request, determines whether or not it is possible to handle therewith by a reissue of the processing request, when the handling is possible, notifies the front node 100 of a retrial command, and, when the handling is impossible, notifies of an error. The front node 100 includes a request distribution unit 101 that, when receiving the notification of the retrial command from the response generation unit 203, reissues the processing request without notifying the business AP 300 of the processing result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
