Yeah, in a RAC environment what makes it angry is trying to call
interface status ioctls on the loopback interface - which of course
isn't a real interface at all. Programatically, there's no reason
Oracle couldn't have had it return some sane error message like, "Tried
to attach to interface that does not support necessary information - ip
(blah) interface (blah)", etc. etc. Instead, the cluster manager just
crashes with gibberish and numbers that obviously indicate type
overflows.
10g is extra dumb, because it actually uses the output from uname() or
gethostname() (we haven't determined which) to determine its node
identity in a CRS config - its not smart enough to store ip
information, or be told that on the fly. When we implemented 10g
support in our software, that was one of the multitude of new 10g RAC
annoyances.
Thanks,
Matt
