I tried to answer her two posts in one post.
To switch a secondary database if the primary database is
down, just test it whether you make a connection to primary
database otherwise you will get SQLException. If you fail
to connect to the primary database, then you use the
secondary. In Oracle, you can set the state of a oracle
instance be offline.
Again this is not a hardware problem.
