<div><p>To enable database files to be visible across a set of <span class="keyword">iSeries™</span> servers, you must first define
|
||
|
|
the group of systems (node group) that you want the files on.</p>
|
||
|
|
<p>A node group can have 2 to 32 nodes defined for it. The number of nodes
|
||
|
|
that is defined for the node group determines the number of systems across
|
||
|
|
which the database file is created. The local system must be one of the systems
|
||
|
|
that is specified in the node group. When the system creates the node group,
|
||
|
|
the system assigns a number, starting with number 1, to each node.</p>

|

A <em>node group</em> is a system object (*NODGRP), which is stored
|

|
|
on the system on which it was created.</li>

Before using the Create Node Group (CRTNODGRP) command or any of the node group commands, you must ensure that the distributed relational database network you are using has been properly set up.</li>
