|
|
<div><p>The Display Node Group (DSPNODGRP) command displays the nodes (systems)
|
||
|
|
in a node group.</p>
|
||
|
|
<p>It also displays the partitioning scheme for the node group (partitioning
|
||
|
|
is discussed later in Partitioning with DB2<sup>®</sup> Multisystem).</p>
|
||
|
|
<div class="p">The following example shows how to display a node group named GROUP1 as
|
||
|
|
well as the partitioning scheme that is associated with the node group. This
|
||
|
|
information is displayed to you at your workstation. For complete details
|
||
|
|
on the DSPNODGRP command, see the Control Language topic in the information
|
||
|
|
center. <pre>DSPNODGRP NODGRP(LIB1/GROUP1)</pre>
|
||
|
|
</div>
|
||
|
|
<p>When you issue the DSPNODGRP command with a node group name specified,
|
||
|
|
the Display Node Group display is shown. This display shows you the names
|
||
|
|
of systems (listed in the relational database column) and the node number
|
||
|
|
that is assigned to the system. This is a direct method for determining what
|
||
|
|
system has what node number.</p>

<p>To see the node number that is assigned to each partition number, use F11
|

|
|
(Partitioning Data) on the Display Node Group display. The next display shows
|
||
|
|
you the node number that is assigned to each partition number. Mapping between
|
||
|
|
the system and the node number (or node number to system) can be easily done
|
||
|
|
by using the DSPNODGRP command.</p>
