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.
