How is MWE (Mixed Workload Enhancement) implemented?

A.
as a feature of the DP2 Disk Process that allows concurrent batch and OLTP to occur without
the batch activity degrading OLTP response times

B.
as a feature of the Scheduler to ensure each process on the ready list receives an equal slice
of available processor cycles

C.
as a methodology of coding applications to ensure OLTP servers will always run at sufficiently
high priority for acceptable response times

D.
as an automatic function of the application compilers to ensure correct priority of OLTP servers
