problem with RMAN duplicate from active database
I'm having a problem with the RMAN duplicate from active database command. I ran this last month to duplicate one of our Prod databases to a test db server without a problem. This month, I am getting an error. I get all the way to the recover command and the duplicate bombs out with the follwing error:
