Thank you for the answer Brian.
Actually: we are not experiencing any freeze or hag. The node is there,
alive. But it refuses connection if a link up is not present on the
interconnect network interface.
You are right: we are using a crosscable since we do not have a gigabit
ethernet switch (and management is not eager to spend thousands of euros
for one *sigh*). However even unplugging it with 9.2.0.4 didn't give us
problem: we got a normal node eviction but the second node went on
giving service.=20
Not so from sunday, when we upgraded.
However the problem would still be there with a switch: what if that
network device is switched off? it would be identical to unplugging a
cable...
RAC used to work even with a cross cable. To check for a working
interface is not a bad thing... but this is not a hardware HA solution
anymore. Only a logical one.
I would use a switch for some testing but I don't have one (maybe I
should revert to 10/100 NIC and using a normal switch).=20
