<div><p>The ability to move processor power dynamically becomes important
|
||
|
|
when you need to adjust to changing workloads. </p>
|
||
|
|
<p>Processors have minimum and maximum values associated with them. These
|
||
|
|
values enable you to establish a range within which you can dynamically move
|
||
|
|
the resource without needing to restart the logical partition. Minimum values
|
||
|
|
dictate what is required to restart the partition. A minimum value of zero
|
||
|
|
is valid. A partition with zero processors or processing units is not functional.
|
||
|
|
For example, a test partition can free up valuable processing power to apply
|
||
|
|
to a production partition if needed. Once the demand on the production partition
|
||
|
|
is over, the processing power can be moved back to the test partition.</p>
|
||
|
|
<p>For both shared and dedicated processors you can specify a minimum value
|
||
|
|
equal to the minimum amount of processing power needed to support the logical
|
||
|
|
partition. The maximum value cannot be more than or equal to the amount of
|
||
|
|
processing power available on the system. If you change either the minimum
|
||
|
|
or maximum value, it will require you to restart the entire partition. If
|
||
|
|
the minimum value is not met for all logical partitions, only the primary
|
||
|
|
will restart.</p>
|
||
|
|
<p><span class="uicontrol">Note for Partitions Not Using DB2 UDB Symmetric Multiprocessing
|
||
|
|
(SMP):</span> Changing processor resources dynamically does not affect
|
||
|
|
the number of tasks used to rebuild database access paths. To apply the processor
|
||
|
|
resource change to database access paths, you need to restart the partition.
|
||
|
|
If you have SMP enabled, no restart is required.</p>
