You can use WebSphere® Virtual Enterprise in a micro-partitioned environment. WebSphere Virtual Enterprise can understand the utilization of shared processor partitions.
A shared processor partition has a metric called Entitled Capacity Percentage. This metric represents the percentage the partition is using of its entitlement at a given point in time. The metric is visible in popular AIX system monitoring tools like the lparstat command, the nmon command, and the topas command.
An uncapped, shared processor partition can be assigned more processing capacity beyond its entitlement. The amount of processing capacity above its entitlement depends on the availability of processors in the shared pool and the maximum amount that the virtual processor configuration allows.
WebSphere Virtual Enterprise Version 6.1.1 and later can understand the utilization of shared processor partitions and the dynamic capacity of the shared processor pool on the physical hardware that is required to operate in a shared processor partition environment.
WebSphere Virtual Enterprise operates in an uncapped, shared micro-partition environment by understanding two important metrics for each partition:WebSphere Virtual Enterprise and the entitled capacity percentage
The entitled capacity percentage represents the percentage the partition is using of its entitlement at a given point in time. This value represents the amount of processing power that is being used by that partition. WebSphere Virtual Enterprise publishes the value from each node agent or middleware agent process every 15 seconds for use by WebSphere Virtual Enterprise autonomic controllers such as the work profiler and dynamic workload manager (DWLM).WebSphere Virtual Enterprise and the maximum entitled capacity percentage
When running on an uncapped, shared micro-partition, the maximum processing power of that partition is not fixed. In other words, the POWER Hypervisor can assign more processing power from the shared processing pool to a partition so that it is using more than its configured entitled capacity. For WebSphere Virtual Enterprise to understand the dynamic processor capacity, it calculates and publishes a metric called maximum entitled capacity percentage. This value represents the maximum percentage of its entitlement that a partition can use.
WebSphere Virtual Enterprise publishes the value from each node agent or middleware agent process every 15 seconds for use by WebSphere Virtual Enterprise autonomic controllers, such as the autonomic request flow manager (ARFM) and the application placement controller (APC). The maximum entitled capacity percentage value is calculated from the idle cycles of the shared processor pool to which the partition belongs. As the utilization of the shared processor pool increases and decreases, the maximum entitled capacity percentage value also changes.
