The Data Integration Service can recover some workflows that are enabled for recovery. Workflow recovery is the completion of a workflow instance from the point of interruption.
A running workflow instance can be interrupted when an error occurs, when you cancel the workflow instance, when you restart a Data Integration Service, or when a Data Integration Service process shuts down unexpectedly. If you abort the workflow instance, the instance is not recoverable.
The Data Integration Service performs workflow recovery based on the state of the workflow tasks, the values of the workflow variables and parameters during the interrupted workflow instance, and whether the recovery is manual or automatic.
Based on your license, you can configure automatic recovery of workflow instances. If you enable a workflow for automatic recovery, the Data Integration Service automatically recovers the workflow when the Data Integration Service restarts.
If the Data Integration Service runs on a grid and the master service process fails over, all nodes retrieve object state information from the Model repository. The new master automatically recovers workflow instances that were running during the failover and that are configured for automatic recovery.
The Data Integration Service does not automatically recover workflows that are not configured for automatic recovery. You can manually recover these workflows if they are enabled for recovery.
Any SQL data service, web service, mapping, profile, and preview jobs that were running during the failover are not recovered. You must manually restart these jobs.
