Administrator's role in automatic recovery

The only role of the administrator in automatic recovery is to bring the coordinator or participant (or both) back online after a system or network failure.

Important: A slow network cannot trigger automatic recovery. None of the recovery mechanisms described here go into effect unless a coordinator system fails, a network fails, or the administrator terminates the coordinating thread.
