  • How to use the Batch Model performance tool

    This article is an introduction on how to use the Batch Model performance tool available in IBM® Navigator for i in version 7.2. Batch Model uses Collection Services performance data to predict batch workload run times, resources used, and the duration of your batch window. It predicts the changes in throughput that result from hardware upgrades (processor or disk) or from a workload increase. It also can help you optimize workloads by providing a timeline view of your batch window, so that you can locate the times when more efficient job scheduling can improve total system throughput.
