<h1 class="topictitle1">Select interactive performance</h1>
|
||
|
|
<div><p>Every physical system is purchased with a specific quantity of
|
||
|
|
interactive performance which is allocated to the partition as a percentage
|
||
|
|
of the total system interactive performance. </p>
|
||
|
|
<p>Interactive performance enables you to run jobs that require user interaction
|
||
|
|
in contrast to batch jobs which require no user interaction. Each partition
|
||
|
|
has a unique requirement for the amount of interactive performance.</p>
|
||
|
|
<p>To move interactive performance, you have to establish a minimum and maximum
|
||
|
|
range within which you can move the resource without needing to restart the
|
||
|
|
logical partition. If you change either the minimum or maximum value you will
|
||
|
|
have to restart the partition.</p>
|
||
|
|
<p>You can specify an interactive performance minimum value equal to the minimum
|
||
|
|
amount of interactive performance needed to support the logical partition.
|
||
|
|
The maximum value must be less than the amount of interactive performance
|
||
|
|
available on the system. The maximum interactive performance is limited by
|
||
|
|
the number of processors in a partition.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Relationship between 5250 interactive capacity, logical partitioning,
|
||
|
|
and Capacity on Demand</h4><p>You allocate 5250 interactive capacity across
|
||
|
|
logical partitions by specifying a percentage of the overall available capacity.
|
||
|
|
The method you use to allocate 5250 interactive capacity to a logical partition
|
||
|
|
works the same on all iSeries™, models, whether the models have standby
|
||
|
|
processors or not:</p>
|
||
|
|
<ul><li>For servers with interactive features, you can allocate a percentage of
|
||
|
|
the interactive feature capacity to be made available for 5250 interactive
|
||
|
|
processing.</li>
|
||
|
|
<li>For Enterprise Edition servers, you can allocate a percentage of the active
|
||
|
|
processor capacity to be made available for 5250 interactive processing .</li>
|
||
|
|
<li>For Standard Edition servers, there is no 5250 interactive processing
|
||
|
|
capacity to allocate. However, up to 100% of the active processor capacity
|
||
|
|
is available to any partition with a single job doing 5250 interactive processing.</li>
|
||
|
|
</ul>
|
||
|
|
<p>The rules for assigning interactive capacity are as follows.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">The server restricts you from assigning more 5250 interactive
|
||
|
|
capacity to a partition than the assigned processor capacity in the same partition.</h4><p>This
|
||
|
|
restriction prevents you from wasting 5250 interactive capacity. For example,
|
||
|
|
for a server with six installed and activated processors, each processor has
|
||
|
|
approximately 16.7% of the total server capacity. For a single-processor partition
|
||
|
|
on this server with an Enterprise Edition, the maximum 5250 interactive allocation
|
||
|
|
can be 17% of the total 5250 interactive capacity, which allows you to allocate
|
||
|
|
slightly more 5250 interactive capacity than the partition's processor capacity.
|
||
|
|
However, you cannot allocate 17% on all of the six one-processor partitions
|
||
|
|
because the total exceeds 100%.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">The percentage of interactive capacity you assign is based
|
||
|
|
on the total number of installed processors, whether they are activated or
|
||
|
|
not.</h4><p>However, you can only use the interactive capacity for activated
|
||
|
|
processors. For example, for a server with six installed processors and three
|
||
|
|
activated processors with three one-processor partition, you cannot allocate
|
||
|
|
more than 50% of interactive capacity across all three processors. This is
|
||
|
|
because you only have access to interactive capacity for the three activated
|
||
|
|
processors. Therefore if you create three one-processor partitions, you can
|
||
|
|
allocate 16.7% interactive capacity for each partition. But if you attempt
|
||
|
|
to allocate 16.7% interactive capacity for two partitions and 30% interactive
|
||
|
|
for the third partition, the third partition will fail.</p>
