Workflow Recovery

Workflow Recovery

Workflow recovery is the completion of a workflow instance from the point of interruption.
When a workflow is enabled for recovery, you can recover a workflow instance if a task encounters a recoverable error, if you cancel the workflow instance, or if the Data Integration Service process shuts down unexpectedly.
View the workflow log to identify the cause of the interruption. After fixing any recoverable errors, you can recover the interrupted workflow instance if it is enabled for recovery.
You cannot change a workflow definition between the interrupted run and the recovery run. If a workflow instance has a recoverable state and you change the workflow metadata in the Developer tool and redeploy the application that contains the workflow, then the workflow instance is no longer recoverable.
The Data Integration Service tries to recover the previous workflow state if the service restarts after an unexpected shutdown. By default, the Data Integration Service does not recover a workflow instance that stopped during a Command task, Mapping task, or Notification task. In addition, the Data Integration Service cannot recover a workflow instance by default if you cancel the workflow instance or cancel a running task in the workflow instance. You can configure the recovery options on the workflow to enable the Data Integration Service to recover a workflow instance in such cases.
When you configure the workflow options, you can configure the workflow for manual recovery or automatic recovery. If you configure automatic recovery, the Data Integration Service restarts the workflow from the point of interruption without any human interaction. If you configure manual recovery, you can restart the workflow.
When a workflow instance recovers or when you recover a workflow instance, the Data Integration Service restarts the task. The service continues processing the subsequent workflow objects. If a workflow instance recovers after a task is interrupted, the Monitor adds an entry for the task instance that runs in the recovered workflow. For example, if a workflow recovers three times and restarts a Mapping task each time, the Monitor contains three entries for the Mapping task.
