Follow the oraclesupport online steps and further refine the steps. The environment is rhel6.2-64 oracle11.2.0.3.

1. First install the IB network card and its driver, and use the command to view the installed network card:

[root@nari65 bin] # ifconfig-a

Ib0 Link encap:InfiniBand HWaddrA0:00:01:00:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00

Inet addr:192.168.12.65 Bcast:192.168.12.255 Mask:255.255.255.0

Inet6 addr: fe80::f652:1403:86:3ae1/64 Scope:Link

UP BROADCAST RUNNING MULTICAST MTU:2044 Metric:1

RX packets:185019 errors:0 dropped:0 overruns:0 frame:0

TX packets:232627 errors:0 dropped:6 overruns:0 carrier:0

Collisions:0 txqueuelen:1024

RX bytes:117911220 (112.4 MiB) TXbytes:324758674 (309.7 MiB)

2. If you use the RDS protocol, you need to modify the linux kernel parameters of all nodes:

Net.core.rmem_default=262144

Net.core.rmem_max=4194304

Net.core.wmem_default=262144

Net.core.wmem_max=2097152

3 the ipoib protocol is the default for the RDS Infiniband Nic. If you use the RDS protocol, modify the contents of the / etc/infiniband/openib.conf file on all nodes, add RDS_LOAD=yes, or change it to yes and change the ipoib parameter to no when this parameter is already no.

# Load IPoIB

IPOIB_LOAD=no

# Enable IPoIB Connected Mode

SET_IPOIB_CM=no

# Load SRP module

SRP_LOAD=no

RDS_LOAD=yes

# Load ISER module

ISER_LOAD=no

4. Verify that the ip address of the IB network card is in the / etc/hosts file, and that the network card is in the private network of RAC.

[root@nari65 bin] # cat / etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

:: 1 localhost localhost.localdomain localhost6 localhost6.localdomain6

# node1

# public

192.168.200.62 nari62

192.168.200.65 nari65

# priv

192.168.12.62 nari62-priv

192.168.12.65 nari65-priv

# vip

192.168.200.32 nari62-vip

192.168.200.35 nari65-vip

# scan_ip

192.168.200.33 racscan

[grid@nari65 ~] $oifcfg getif

Eth0 192.168.200.0 global public

Ib0 192.168.12.0 global cluster_interconnect

5. If you originally used the ipoib protocol, you need to shut down all node oracle services.

[root@nari62 bin] #. / crsctl stop crs

6. After confirming that the service is turned off, use oracle users to relink on all nodes.

[oracle@nari65~] $cd $ORACLE_HOME/rdbms/lib

[oracle@nari65~] $make-f ins_rdbms.mk ipc_rdsioracle

7, after relink, use root to start the oracle service of all nodes again.

[root@nari62 bin] #. / crsctl start crs

If you look at the alert-log file, you can see that it is already a rds protocol:
