Display Node Group (DSPNODGRP) command

The Display Node Group (DSPNODGRP) command displays the nodes (systems) in a node group.

It also displays the partitioning scheme for the node group (partitioning is discussed later in Partitioning with DB2^® Multisystem).

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.

DSPNODGRP NODGRP(LIB1/GROUP1)

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.

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.

The following example prints a list of the systems in the node group named GROUP2 as well as the associated partitioning scheme:
