10-5. Managing Grid Infrastructure Network Resources
Problem
You wish to validate the Oracle 11gR2 Grid Infrastructure network resources and configuration on Exadata in order to
confidently manage your Grid Infrastructure network components.

Solution
In this recipe, you will learn how to identify and manage the following 11gR2 Grid Infrastructure network components
and resources:

• The Oracle Cluster High Availability IP framework, or HAIP

ora.net1.network Oracle cluster resource • The

• The virtual IP addresses, or VIPs

• The SCAN network and SCAN listeners

• The database listeners

Validate your Oracle Cluster High Availability IP Framework
Start by examining your Oracle's Cluster High Availability IP framework, or HAIP. This is the interface upon which
your Oracle RAC interconnect is deployed. You can find the details of the cluster HAIP by querying the relevant
cluster resource:

[root@cm01dbm01 ~]# /u01/app/11.2.0.3/grid/bin/crsctl stat res -init -w "TYPE = ora.haip.type"
NAME=ora.cluster_interconnect.haip
TYPE=ora.haip.type
TARGET=ONLINE
STATE=ONLINE on cm01dbm01
[root@cm01dbm01 ~]#

Using oifcfg , you can find where Oracle places the InfiniBand network. Following, we see that the cluster
interconnect is on network 192.168.8.0 , using the bondib0 interface:

[root@cm01dbm01 ~]# /u01/app/11.2.0.3/grid/bin/oifcfg getif
bondib0 192.168.8.0 global cluster_interconnect
bondeth0 172.16.10.0 global public
[root@cm01dbm01 ~]#

Validate Your ora.net1.network Oracle Cluster Resource
Log in as the Grid Infrastructure owner and confirm the status of the ora.network.type cluster resource:

[grid@cm01dbm01 ~]$ crsctl stat res -w "TYPE = ora.network.type"
NAME=ora.net1.network
TYPE=ora.network.type
