Thanks for your response !!
I understand this branding stuff but i am expecting this from API perspective.
Though this wrappers has changed we are still managing same hardware resources.
So to have a keen watch on my resources i need to write some scripting (in java).
Now the problem is some of the API was there with DFM 5.x and prior versions but since OCUM major API's are not there in the documentation.
A big example for this is Host.
So is it the case that we cannot have a concept like Host since OCUM 6.x?
