Could you Please Elaborate with an Example for doing the "Undo  Undo Action " ? For Eg : I have Database "DemoDB" Which i Restored in Target Server With StandBy Option by specifying a file path to store the Undo Actions. So , How do i undo the undone actions using  the file I  have ?

Any help would be really apprecited
