ORA-16799: Redo Apply is not running

What triggered the Error:

Either the Data Guard broker metadata indicates that Redo Apply was turned off, or the recovery process, MRP0, was not running. As a result, Redo Apply-related properties could not be set.

What should we do to fix it:

Turn on Redo Apply through Data Guard broker and reissue the command to set a Redo Apply-related property.
