There are two ways for an HiRDB system to use a DNS server to manage IP addresses:
This section describes how to manage each of these configurations.
If the server machines reside in the same domain, specify either the host name or the FQDN (fully-qualified domain name; maximum of 32 characters) as the host name in the pdunit and pdstart operands. In this way, a DNS server can manage IP addresses, thereby making the hosts file unnecessary.
Basically, the host name or FQDN is specified using the following options:
Figure 25-6 shows an example system configuration using a single domain.

The following is an example of how to specify pdunit -x in this case:
If the server machines reside in multiple domains, specify the FQDN (fully-qualified domain name; maximum of 32 characters) as the host name in the pdunit and pdstart operands. In this way, a DNS server can manage the IP addresses, thereby making the hosts file unnecessary.
Basically, the FQDN is specified using the following options.
Figure 25-7 shows an example system configuration using multiple domains.
