For some reason, I thought there was a special case for DRL and
Oracle. Now that I think about it, it doesn't make any sense. Maybe I was

DRL is just for mirrors, but is there are another level of logging that
needs to be disabled for oracle datafiles, and enabled for redo logs,
since redo logs contain all the needed recovery information for data
