Hi Sanjay,
I have good experience with HAIP, too. Usually it causes less discussions w/
sysadmins and network staff, and is less prone to missing switchovers due to
misconfigured bonding methods (or mis-coordinated ones, speaking of switch and
bond configs).
Important, as Stefan already pointed out, use seperate networks for each
"channel". But as I know from my current RAC project, just a little subnetting
on your interfaces will do, don't mess with the sleeping network lions...

Betreff: Oracle RAC multiple Nic for Private network vs interconnect bonding
Hi
Can someone share his experience in using multiple NIC for Private network and
therby focing Oracle to use multiple HAIP vs interconnect bonding. I had RAC
setup where OS level Private network Bonding is not failing over due to one
issue on NIC and causing Oracle cluster to bounce the node. This happen
several
time and so checking Oracle Docs that says that 11g(11.2) onwards it is
recommended to use multiple nic and details from DOc is
"With Redundant Interconnect Usage, you can identify multiple interfaces to
use
for the cluster private network, without the need of using bonding or other
technologies. This functionality is available starting with Oracle Database 11
g Release 2 (11.2.0.2). If you use the Oracle Clusterware Redundant
Interconnect feature, then you must use IPv4 addresses for the interfaces.
When you define multiple interfaces, Oracle Clusterware creates from one to
four
highly available IP (HAIP) addresses. Oracle RAC and Oracle Automatic Storage
Management (Oracle ASM) instances use these interface addresses to ensure
highly available, load-balanced interface communication between nodes. The
installer enables Redundant Interconnect Usage to provide a high availability
private network.
By default, Oracle Grid Infrastructure software uses all of the HAIP addresses
for private network communication, providing load-balancing across the set of
interfaces you identify for the private network. If a private interconnect
interface fails or become non-communicative, then Oracle Clusterware
transparently moves the corresponding HAIP address to one of the remaining
functional interfaces."
So want to check is someone is using and share the experience
TIA
