"but they should configure them as an alias or whatsoever". By alias, I mean network interface alias.

Awesome explanation. I always wondered about the virtual IP but never got a hang of it until I see your video. Thanks for explaining very well and with a good demonstration of the video. I am now trying to understand SCAN IP (11g). Do you have any video that explains about this?

Alex what are you saying in your video at 7:30-7:32? I can't for the life of me understand lol. You were saying something about not letting your system admin configure your VIPs as something, but I can't understand what it is you said.

thanks

Thanks Alex...good stuff...one minor thing...it would be nice to visualise where the "failed" vip is located...e.g., in crs_stat output...Keep up the good work!
