I can tell I did not make myself very clear here.  I will try to explain 
what I'm looking for.  Support for VAG on z/VM comes to an end.  As a 
result all our business VM applications will be converted to eventually 
run on z/OS.  I was asked to make a simulation of the costprize of the 
to-be situation after the conversion.  Billing to the client is based on 
CPU-seconds.  Batch takes about 80% of system resources in terms of cpu. 
Given the same DB/2 batch job ( consider DB/2 on MVS being the same ), 
same database volume, same z9 Server and so on, so take only z/VM and the 
z/OS cpu cycles into account, would there be a difference and if so, how 
big would that difference be ?

regards,
Koen.
