HP e-Commerce/XML Director Server Appliance SA8250 Getting Started Guide

Configuring DNS

We recommend using IP addresses for the fastest performance. You

can also use a host table in the SA8250 when IP addresses are not

assigned via DHCP. The host table makes SA8250 restarts faster and

eliminates the chance of service failure due to DNS errors and time-

outs.

Using a DNS

Server

The SA8250 is sometimes required to identify itself and other devices

on its network by name and IP address. If your site has a DNS server

that contains the names of the SA8250 and servers, the SA8250 can

be configured to recognize these by entering the DNS addresses in the

SA8250’s Boot Monitor.

Host name resolution is always performed in the following order:

1. Local static hosts table

2. Primary DNS server

3. Secondary DNS server

Using the

SA8250

without a DNS

Server

Another way is to add hosts to the SA8250’s host tables, which

contain an IP address and hostname for each device.

Host tables are managed using the CLI. This procedure walks you

through the naming and addressing setup for the SA8250.

For more information on the CLI, see Chapter 5 in the User Guide.

Configure the hosts file to avoid DNS dependency

A static hosts table and DNS servers can be used in concert. When a

hostname is not resolved by static hosts table lookup, the SA8250 will

use the DNS server.

1. Enter the following into the SA8250’s hosts file to avoid the need

for DNS:

• The SA8250's own name (automatically entered by the Boot

Monitor program, though you can subsequently change it)

• The backup SA8250's name (if using serial cable failover, see

Chapter 3 of the User Guide)

• The “online” SA8250 name (if using serial cable failover)
