It depends entirely on what the requirements of your application are. If
you have a small number of persistent objects where all the state is
visible from the production and backup servers, you could configure
additional endpoints in the object references so clients automatically
fail-over to use the backup if they can't contact the production server.
If your objects are stateful, you have to do whatever is necessary to
continue processing with a different server.

If you post some more details about what your application does, people
might be able to offer some more specific suggestions.

Cheers,

Duncan.
