Dear all
I have to declaire the further information about the MAC that deployed since yesterday. 
- First, any kind of support. We cannot by there is no MAC for testing. So the configuration or else, we have no idea. 
- Second, at currently stock, if you found any issues from MAC we have no spare machine to change immediatly. 
- Last, the MAC requesters are the customer support or testing objectives so IBMSD don't have the information about the Application that you use. 
So we cannot answer the whole question that you ask via 4555 krub.
