Hie,

In my project I am using webservice to expose some functionality
dependent on bdbxml. The webservice hosting environment(Axis2 on
Tomcat) already provides fault tolerance through clustering. And, I
also found out that bdbxml provides replication api too. Is there any
way to handle replication of both tiers at one time.
On architectural level I am worried about the situation, if I am going
to manage both tiers independently then the situation might occur that
server is on one machine and db is on other, that I suppose both should
be placed on one machine.

I think this is a usual fault tolerance problem where every database's
business logic is exposed by any presentation layer technology. As I am
bit new to this area, kinldy help me.

Thanks in advance
