23.2 Settings for a DNS server to manage IP addresses

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.

Organization of this section
(1) How to set up HiRDB in a single domain
(2) How to set up HiRDB in multiple domains

(1) How to set up HiRDB in a single domain

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:

The following figure shows an example of a system configuration using a single domain.

The following is an example of how to specify pdunit -x in this case:

(2) How to set up HiRDB in multiple domains

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.

The following figure shows an example of a system configuration using multiple domains.
