A Closer Look at How to Set up a Parsing-Only Workload - comment by carrie

Nick,
 
Parsing prioritization is based upon the concept of session classification.  Session classification happens with TASM if you are on either SLES 10 or SLES 11.   It also happens on SLES 11 with TIWM (workload management for the appliance and EDW non-TASM platforms). 
 
As long as you are using workloads, you will see WDIDs and SessionWDIDs show up in DBQL, and SessionWDID will tell you what workload parsing took place in.   So if you have workloads, there is no reason you cannot manipulate session classification to point to a high priority workload for your parsing needs, if you wish.   
 
Parsing prioritization is not determined by the operating system (SLES 10 vs. SLES 11), but rather if you are using workloads and if session classification is taking place.
