Oracle RAC modifies private IB NIC protocol for RDS Protocol

follow the oraclesupport online steps to further refine the process and the environment is rhel6.2-64 oracle11.2.0.3

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

[Email protected] 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 for all nodes:

net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=2097152

3,the InfiniBand NIC is the IPOIB protocol by default and is modified at all nodes if using the RDS protocol /etc/infiniband/ openib.conf file contents, add Rds_load=yes, or already have this parameter no, modify to Yes, and modify the IPOIB related parameter to 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, confirm The IP address of the IB network card in the/etc/hosts file, and verify that the NIC is in the private network of the RAC

[Email protected] 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

[Email protected] ~]$ oifcfg getif

Eth0 192.168.200.0 Global Public

Ib0 192.168.12.0 Global Cluster_interconnect

5, If the original is using the Ipoib protocol, you need to shut down all nodes Oracle services.

[[email protected] bin]#./crsctl Stop CRS

6, after confirming the service shutdown, use the Oracle user to relink on all nodes .

[[Email protected]~]$ cd $ORACLE _home/rdbms/lib

[Email protected]~]$ make-f ins_rdbms.mk ipc_rdsioracle

7, after relink, use ROOT to start the Oracle service for all nodes again .

[[email protected] bin]#./crsctl start CRS

View The Alert-log file to see the RDS protocol already:
