5) Exibe informações do IP privado.
$./olsnodes -n -i -l -p exadatadm01vm011172.16.2.63exadata01vm01-vip
As informações de rede pública e privada são armazenadas no Oracle Cluster Registry (OCR).
$./oifcfg getif bondeth0 192.168.16.0 global public ib0 172.16.0.0 global cluster_interconnect
“cluster_interconnect” — Interface Privada no Oracle Clusterware
O comando iflist consulta o sistema operacional para descobrir quais interfaces de rede estão presentes no node.
O comando iflist mostra as interfaces disponíveis que você pode configurar com o “setif”.
-p exibe o tipo de interface que pode ser PRIVATE, PUBLIC ou UNKNOWN
-n inclui a máscara de sub-rede
$ ./oifcfg iflist -p -n eth0 192.168.1.0 PRIVATE 255.255.255.0 bondeth0 192.168.16.0 PRIVATE 255.255.255.0 bondeth1 10.70.156.0 PRIVATE 255.255.255.0 ib0 172.16.0.0 PRIVATE 255.255.252.0 ib0 169.254.0.0 UNKNOWN 255.255.0.0 ib1 172.16.0.0 PRIVATE 255.255.252.0
