Chances are the two vpars are fairly idle like the example screenshot, and because neither is busy,
the vpars each have their own value of 4 cores. To see lending and borrowing of CPU resources,
force some activity onto one of the virtual partitions, for example cutst128.
In this next screenshot, you see the SRD view again, but cutst128 has borrowed cores from cutst125.
To see the cutst128 workload’s behavior in real time, we select its bar graph in the CPU Utilization
column (or select the workload and then Report->gWLM Real-time Reports…). The next
screenshot shows such a graph shortly after cutst128’s appetite, and then its allocation, ramped up.
In a similar fashion, you can stress the SAP instances in one of your vpars and watch gWLM move
any unused cores to that vpar, and then return them when the workload demand decreases again.
