I was using Teradata Manager and suddenly the Teradata Database 12.0 got hung up. I checked the Teradata Service Control and it is just showing up "PDE state is RUN/STARTED" and not "Teradata is running". Can you advise how do I start up the Teradata again.I have tried restarting the Teradata from the options but it gets back to the same state. Also tried restarting the pC and the same status. Tried Stop Teradata and Start Teradata and the same.
