WlS: optimization of domain design for multiple managedserver

Dear all,

I would like to know your suggestions regarding best and/or optimal design for 3 environments: dev, Test, production that they have multiple ManagedServer with same application (Forms, Reports). But we need to separate them better response time. We are preparing a WebLogic Suite (10.3.6) installation and that's mean for better performance (perahps) we can use Coherence too, but I'm not sure, if we can use Coherence for FRD.

I would like to classify the topics:

- Which aspects are important for a domain design?

- make it sense if we are prepare the multiple domains in one WLS Suite installation? Advantage/disaavantage
