herein lies the main concern I have.  DG is great for
keeping a database replicated, yes, but upon switchover
there needs to be the total environment there...all the
stuff the site has **outside** the database for the workflow.
Such things as UTL_FILE stuff, external tables, scripts,
etc... seems storage level would be the only way to
have the operations environment replicated.
