Enforcement Priority: Soft, Hard, or Just Window-Dressing? - comment by carrie

Response to your second question:
 
Enforcement priority and allocation groups no longer apply only when you move to SLES 11 operating system.  They only apply to SLES 10 priority scheduler.
 
For information and background on how SLES 11 priority scheduler works, please read the SLES 11 Priority Scheduler orange book.
