Well,
that is because of your understanding of the word "failover". Don't be confused,
there are other words
in
desperate need of redefinition, too. One of them is "unbreakable".
To
make the long story short, "FAILOVER=ON" makes possible for Oracle*Net to
skip the non-functioning
TNS
descriptor, not that the application should simply fail over and continue from
another node. The application
will
simply fail, without the desired "over", unless it's written using OCI, which is
the only means for an
application to resume on one of the surviving nodes. In other words, it
is the TNS descriptor that "fails over",
not
your application. I hope that things are clearer now.
