Hello everyone,
We have recently installed 10gR2 RAC + ASM on 2 Sun servers running
Solaris 10 OS. Since we started using the system (before applying
patch 10.2.0.3) we have been observing a rather strange behaviour.
We start the CRS, nodeapps, asm and finally the database. crs_stat -t
reports everything to be fine. Then, after a random period of time,
one of the nodes' vip is lost, resulting to the eviction of the node.
After applying the patch, the node is not evicted, the vip is
reassigned to the other node and the instance keeps functioning
properly. BUT, the vip continues to fail on random intervals.
After searching through the OS's logs, in /var/adm/messages we get a
message that the qfe (public IP nic) gets turned off and restored in
a second at the specific moments that the vip service gets losts.
After we experimented enough, we came to the discovery that if we
keep pinging endlessly the public IPs of the the 2 nodes, the qfes of
both the servers never get turned off and on. This way the RAC
performs without any problems.
Can someone of you explain this behavior? Is there something we are
missing during or post installation? Is this a Solaris problem, an
Oracle problem or a HW problem? We have almost eliminated the
posibility for a NIC problem, since we switched the qfe nic for the
ce nic (previously used for the interconnect) and we get the same
behavior, this time for the ce card.
Any help and/or guidance is extremely welcome since we seem to run
out of options and directions. If anyone is interested, we will
gladly provide any logs or elaborate on the matter.
Thank you very much for your time and interest.
