How does a client changes from provider to consumer when provider is down

[Kaveh Ehsani]

I have setup a provider/replicator(consumer) with a client and all functioning 
well. Except when I switch off the provider, the client does not read from the 
consumer. Of course I have not told the client to do so any where, not sure 
where to do this. I can set it up manually but there has to be a way for a 
switch to take place automatically. Thanks, for all the feedbacks.
