[oracle@node1 bin]$ ./olsnodes -help
Usage: olsnodes [-n] [-p] [-i] [<node> | -l] [-g] [-v]where-n print node number with the node name-p print private interconnect name with the node name-i print virtual IP name with the node name<node> print information for the specified node-l print information for the local node -g turn on logging -v run in verbose mode [oracle@node1 bin]$

-n显示每个节点编号
-p显示每个节点用于private interconnect网卡名称
-i显示每个node vip
-g:打印日志信息
-v:打印详细信息

显示每个节点的ID:
[oracle@node1 bin]$ ./olsnodes -n
node1   1
node2   2
[oracle@node1 bin]$显示用于private interconnect网卡名称：
[oracle@node1 bin]$ ./olsnodes -n -p
node1   1       rac1-priv
node2   2       rac2-priv
[oracle@node1 bin]$ 显示每个节点的vip：
[oracle@node1 bin]$ ./olsnodes -n -p -i
node1   1       rac1-priv       rac1-vip
node2   2       rac2-priv       rac2-vip

12         <nodename> - name of the host, as known to a communications network
13         <if_name>  - name by which the interface is configured in the system
14         <subnet>   - subnet address of the interface
15         <if_type>  - type of the interface { cluster_interconnect | public | storage }

显示网口列表:
[oracle@node1 bin]$ ./oifcfg iflist
eth0  192.168.2.0
eth1  10.0.0.0获得网口信息(名称，网段地址，接口类型3个属性)：
[oracle@node1 bin]$ ./oifcfg getif
eth0  192.168.2.0  global  public
eth1  10.0.0.0  global  cluster_interconnect注：eth0接口的网段地址是192.168.2.0，网卡类型是public，也就是用于oracle net和vip；配置类型global说明所有节点的eth0网卡都属于192.168.2.0网段并都是public类型。查看public 类型的网卡：
[oracle@node1 bin]$ ./oifcfg getif -type public
eth0  192.168.2.0  global  public查看cluster_interconnect 类型的网卡：
[oracle@node1 bin]$ ./oifcfg getif -type cluster_interconnect
eth1  10.0.0.0  global  cluster_interconnect添加接口配置
[root@raw1 bin]# ./oifcfg setif -global eth0/192.168.1.119:public
[root@raw1 bin]# ./oifcfg setif -global eth1/10.85.10.119:cluster_interconnect删除接口配置
[root@raw1 bin]# ./oifcfg delif -global
