Ken, My guess is that the Oracle kernel is slogging away. You could bounce the instance, but you might end up wrecking something worse. I think the moral to the story is to be extremely careful what commands you issue in production and any command you aren't entirely comfortable with, issue it on test first. Another alternative would have been to issue the "set unused" parameter on this command. Hang in there.
