How to set my Linux machine to have two network cards with two IPs

Dear all gurus out there,

I am newbie to Linux and networking.

I have a Red hat linux that used as a Database machine, oracle.

I have 2 network cards that I wish to set to 192.168.0.10 and
192.168.0.11 respectively, the default gw is 192.168.0.1. The
connection of the two IPs coming from 2 different switches (still from
the same router).

My purpose is that : if one of the switches is down, my connection
still up with the other side.

I know switch is hardly "down", but i wish to have full redundancy.

What I did is, I jus set the 2 network cards with the two IPs and I
switch off one of the switches, "poof" the whole network
down..........so, how can it be done ?

Or any other alternatives ?


Thanks.
