DNS Perhaps the most common short name resolution option is Domain Name Service (DNS).
As with the hosts file, it is good practice to place all the network names of your
GroupWise resource groups into DNS.
For short name resolution to work using DNS, the client workstation must either belong to
the same DNS zone (such as support.novell.com) as the resource group, or the cluster
resource zone must be configured in the client's DNS suffix search path under TCP/IP
settings for the workstation.
Specific setup instructions for each of these short name resolution methods are provided in

GroupWise resource groups.
33.8 Deciding How to Install and Configure the
Agents in a Cluster
There are several cluster-specific issues to consider as you plan to install the Windows MTA and
POA in your clustered GroupWise system:
Section 33.8.1, "Planning Cluster-Unique Port Numbers for Agents in the Cluster," on
page 283
Section 33.8.2, "Deciding Where to Install the Agent Software," on page 285
Section 33.8.3, "Planning the Agent Services," on page 287
Section 33.8.4, "Planning the Windows Agent Installation," on page 287
33.8.1 Planning Cluster-Unique Port Numbers for Agents in the
Cluster
By default, the GroupWise agents listen on all IP addresses, both primary and secondary, that are
bound to the server on their specified port numbers. The primary IP address is the IP address of the
physical node. Secondary IP addresses are the IP addresses associated with GroupWise resource
groups.
Any time there is a possibility of two of the same type of agent running on the same node, it is
important that each agent use a cluster-unique port number, even though each agent is using the
unique IP address established for each GroupWise resource group. The best way for you to avoid
port conflicts is to plan your cluster so that each agent in the cluster runs on a cluster-unique port.
