or more inactive processor, place an MES order for the desired quantity of the
model-specific activation code, as follows:
#1604 CUoD Activation for the Model 840
#1605 CUoD Activation for the Model 830
#1610 890 CUoD Activation for the Model 890
Ordering a CUoD activation feature generates an activation code, which is
posted on a Web site and mailed to the customer. This activation code must be
entered on the IBM Eserver i5 or iSeries server console.

Capped and uncapped partitions

Partitions in a shared processing pool can have a sharing mode of capped or

processing power for a partition and the workload demand needed at a particular
time assuming you have free resources in a shared pool.
Use capped mode when a software application never requires more than a
certain amount of processing power. Any unused processing resource is used
only by the uncapped partitions in the shared processing pool.
Uncapped capacity is limited to the minimum of the number of virtual processors
assigned to the partition and the capacity of the shared pool. If two partitions
need additional resources at the same time to complete a job, the server can
distribute the unused processing resources to both partitions. This distribution
process is determined by the uncapped weight of each of the partitions.
Uncapped weight is a number that you set for each uncapped partition in the
shared processing pool. By setting the uncapped weight, any available unused
capacity is distributed to contending LPARs in proportion to the established value
of the uncapped weight.
