Chapter 39      Centralized Management Using Clusters
  Managing Clusters
Use the 
clustermode
 command to switch between different modes.
The prompt in the CLI changes to indicate your current mode. 
or 
In machine mode, the prompt will include the fully qualified domain name of the machine.
Copying and Moving Settings
All non-restricted (see 
) commands have new operations: 
CLUSTERSHOW
 and 
CLUSTERSET
CLUSTERSHOW
 is used to show in which modes a command is configured 
(see 
). The 
CLUSTERSET
 operation allows you to move or copy the 
current settings (configurable with the current command) from one mode to another or between levels 
(e.g. from a machine to a group).
copy retains the settings for the current mode. A move resets (clears) the configuration of the current 
mode; i.e., following a move, no settings will be configured for the current mode.
For example, if you have configured Good Neighbor Table settings (the 
destconfig
 command) for group 
northamerica
, and you decide that you want the entire cluster to have these settings, you can use the 
clusterset
 operation from within the 
destconfig
 command to copy (or move) the current settings to 
the cluster mode. (See 
.) 
Caution
Exercise caution when moving or copying configuration settings to avoid inconsistent dependencies. For 
example, if you move or copy listeners with disclaimer stamping configured to another machine, and that 
new machine does not have the same disclaimers configured, disclaimer stamping will not be enabled on 
the new machine. 
Experimenting with New Configurations
One of the most advantageous ways to use clusters is to experiment with new configuration settings. First 
you make changes at the machine mode, in an isolated environment. Then, when you are satisfied with 
your configuration, you move those configuration changes up to the cluster mode to make them available 
on all machines.
