20120210323 | DATA PROCESSING CONTROL METHOD AND COMPUTER SYSTEM - A rerunning load is reduced for reducing the risk of exceeding a specified termination time after abnormally ending a job net. Even if the same data processed by jobs within a job net is replaced with split data of sub-jobs and some of sub-jobs have been abnormally ended, the job net is continued. For each split data, a state and/or an execution server ID of each job are stored, and the progress of a job net is managed. Only split data whose state is not “normal” is to be processed by rerunning. Based on states of execution servers, on whether or not intermediate files transferred between jobs is shared among execution servers, and on whether or not an output file is deleted after ending the subsequent job, it is judged whether or not intermediate files can be referred to and from what job the rerun is to be performed. | 08-16-2012 |
