Thanks a lot, guys.
Since I only want to configure RAC for testing purpose. I guess I will skip the NICs for backups, and no redudancy. Now if I have 2 NICs in my 2 linux machines. Can I connect them like:

Server A Server B
NICA_1 ------ NICB_1 (regular DB traffic) NICA_2 ------ NICB_2 (interconnect)

Are both connections just the normal direct network cable connections(other than cross cable)? Received on Wed Jan 15 2003 - 09:46:41 CST
