AIX

Hello All,

I want to install ORACLE RAC on AIX 6.1.
In the installation guide. the below two points were mentioned:

Each node must have at least two network adapters or network interface cards
(NICs): one for the public network interface, and one for the private network
interface (the interconnect).

How can i check if i have two network adapters or network interface cards?
If i do not have how can i add ?

Before starting the installation, you must have at least two interfaces configured on
each node: One for the private IP address and one for the public IP address.

How can i do that ?

A DHCP service running on the public network for the cluster

How can i check if DHCP service is running ? in case not how can i run it ?

Well, you will not want to use DHCP for your database servers. Use static adresses. You can check the available adapters with

Code:

lsdev -C | grep ent

and the configured IP adresses with

Code:

ifconfig -a

Why i will not want to use DHCP is there any disadvantage ?
