6-2. Configuring DNS
Problem
You wish to configure your DNS servers to support an Exadata installation.
Solution
DNS configuration is a prerequisite to a successful Exadata Database Machine installation. As outlined in Recipe 6-1,
your Exadata configuration will have multiple IP addresses and use your entered database machine name to identify
hostnames for each server and component inside your Exadata.
After completing your configuration worksheet, Oracle or your Oracle Partner will send you a script called
checkip.sh
and an associated
dbm.dat
file. The purpose of
checkip.sh
, as outlined in Recipe 6-3, is to validate your
DNS and network configuration for all Exadata network components as specified in your configuration worksheet.
For
checkip.sh
to succeed and to ensure a smooth Exadata installation, use the values you supplied in your
configuration spreadsheet and enter the following fully qualified hostnames in your DNS servers:
•
SCAN names and addresses
•
Compute server names and addresses
•
Cell server names and IP addresses
•
VIP names and IP addresses
