When a particular Job/Jobs present in the Jobflow failed due to connection server issues need to choose the “Restart from Failure” option In DI Suite  àMonitor for that particular Jobflow. Which will run the job present in the Jobflow from the failure point rather than from the start of the Job.

Please Note: When we make any changes in the Jobflow or the parent objects related to the Jobflow or Job or dataflow. We need to run the Job from the start as the Jobflow is recompiled.
