How Resources are Shared in the SLES 11 Priority Scheduler - comment by carrie

Samir,
 
Just to be sure that I understand what you mean when you say   " In workload distribution, i see that we have only tactical and timeshare defined"  Are you talking about the Prod or Dev virtual partition?
 
Workload Distribution screen only shows one virtual partition's workloads at a time.   If your question is how to see the workloads from the other virtual partition:  There is a down arrow next to the virtual partition name near the top of the Workload Distribution screen which will allow to you select the other virtual partition's workloads.
 
In addition, if you click on the "System Workload Report" button on the top right side of the Workload Distribution screen, you can see the global weights that will be distributed to each workload within each virtual partition.   There is a blog posting that explains what global weight is and how to find it in Viewpoint:

Sharing of resources among multiple virtual partition works the same as sharing resources among multiple workloads.  If the queries that run in the virtual partition are not using their allocated resource, that resource will be available to be used by work running in the other virtual partition.  The orange book titled:  "Priority Scheduler for Linux SLES 11" provides more information on virtual partitions.
