It may be bad form to reply to yourself in this NG, but also look at this link which has a wealth of scenarios to work with as well.

http://www.psoug.org/reference/rman_demos.html

Also, I didn't say it, but PIT recovery is also good to be familiar with as well.

Best to be well versed in this and have ample documentation, or some recipe-like documentation on what to do, because these databases tend to crash usually at inconvenient times e.g.

if issleeping($DBA) or onvacation($DBA) then

    database_crash();
else

    database_function_smoothly();
fi

It seems to be set up that way.
