We changed the weight for the partition oli to the maximum value 255 while
partition julia is set to 128.
The operation can be performed dynamically. For accessing the GUI menus,
from the Server Management menu of the HMC, right-click on the partition
name and select Dynamic Logical Partitioning → Processor Resources
→Add (as shown in Figure 14).
Figure 14 Dynamically changing the weight of the partition
When both partitions are heavy CPU loaded, the amount of processing units
allocated from the processor shared pool is proportional to the weight value of
the partitions.
