10g Release 1 (10.1) for hp OpenVMS Alpha
Part No. B13681-01
The Oracle 10g installation guide for OpenVMS states that :
2.2.2 IP Address Requirements
Before starting the installation, you must identify or obtain the following IP addresses for each node:
o An IP address and an associated host name registered in the domain name service (DNS) for each public network interface
o One unused virtual IP address and an associated virtual host name registered in the DNS that you must configure for the primary public network interface
The virtual IP address must be in the same subnet as the associated public interface. After installation, you
can configure clients to use the virtual host name or IP address. If a node fails, then its virtual IP address fails
over to another node.
o A private IP address and an optional host name for each private interface
Oracle recommends that you use nonroutable IP addresses for the private interfaces, for example,
10.*.*.* or 192.168.*.*.. You can use the local TCP/IP database on each node to associate private host
names with private IP addresses.
o One private IP address for each node to serve as the private interconnect
This IP address must be separate from the public network, and it must have the same interface name
on every node that is part of the cluster.
