Configuring Workflow Recovery

Configuring Workflow Recovery

To configure a workflow for recovery, you must enable the workflow for recovery or configure the workflow to suspend on task error. When the workflow is configured for recovery, you can recover it if it stops, aborts, terminates, or suspends.
The following table describes each recoverable workflow status:
Status
Description
Aborted
You abort the workflow in the Workflow Monitor or through
pmcmd
. You can also choose to abort all running workflows when you disable the service process in the Administrator tool. You can recover an aborted workflow if you enable the workflow for recovery. You can recover an aborted workflow in the Workflow Monitor or by using
pmcmd
.
Stopped
You stop the workflow in the Workflow Monitor or through
pmcmd
. You can also choose to stop all running workflows when you disable the service or service process in the Administrator tool. You can recover a stopped workflow if you enable the workflow for recovery. You can recover a stopped workflow in the Workflow Monitor or by using
pmcmd
.
Suspended
A task fails and the workflow is configured to suspend on a task error. If multiple tasks are running, the Integration Service suspends the workflow when all running tasks either succeed or fail. You can fix the errors that caused the task or tasks to fail before you run recovery.
By default, a workflow continues after a task fails. To suspend the workflow when a task fails, configure the workflow to suspend on task error.
Terminated
The service process running the workflow shuts down unexpectedly. Tasks terminate on all nodes running the workflow. A workflow can terminate when a task in the workflow terminates and you do not have the high availability option. You can recover a terminated workflow if you enable the workflow for recovery. When you have high availability, the service process fails over to another node and workflow recovery starts.
A failed workflow is a workflow that completes with failure. You cannot recover a failed workflow.
