1. Display the current scan configuration
$ srvctl config scan SCAN name: exadata-pscan1, Network: 1 Subnet IPv4: 192.168.16.0/255.255.255.0/bondeth0, static Subnet IPv6: SCAN 0 IPv4 VIP: 192.168.16.43 SCAN VIP is enabled. SCAN VIP is individually enabled on nodes: SCAN VIP is individually disabled on nodes: SCAN 1 IPv4 VIP: 192.168.16.41 SCAN VIP is enabled. SCAN VIP is individually enabled on nodes: SCAN VIP is individually disabled on nodes: SCAN 2 IPv4 VIP: 192.168.16.42 SCAN VIP is enabled. SCAN VIP is individually enabled on nodes: SCAN VIP is individually disabled on nodes:
2. Obtain information about SCAN DNS records.
$ nslookup exadata-pscan1 Server: 192.168.16.20 Address: 192.168.16.20#53 Name: exadata-pscan1 Address: 192.168.16.41 Name: exadata-pscan1 Address: 192.168.16.42 Name: exadata-pscan1 Address: 192.168.16.43
Where: 192.168.16.41, 192.168.16.42 e 192.168.16.43 are the SCAN IPs
3. Display Cluster Name
$./olsnodes -c exadata-pclu1
4) Display the PUBLIC and VIP Node name.
$ cd /u01/app/12.1.0.2/grid/bin/ $ ./olsnodes -n -i exadatadm01vm011exadata01vm01-vip exadatadm02vm012exadata02vm01-vip $./srvctl config nodeapps -a Network 1 exists Subnet IPv4: 192.168.16.0/255.255.255.0/bondeth0, static Subnet IPv6: Ping Targets: Network is enabled Network is individually enabled on nodes: Network is individually disabled on nodes: VIP exists: network number 1, hosting node exadatadm01vm01 VIP Name: exadata01vm01-vip VIP IPv4 Address: 192.168.16.46 VIP IPv6 Address: VIP is enabled.

VIP is individually enabled on nodes: VIP is individually disabled on nodes:
5) Display Private IP information
$./olsnodes -n -i -l -p exadatadm01vm011172.16.2.63exadata01vm01-vip
Public and private network information are stored in Oracle Cluster Registry (OCR).
$./oifcfg getif bondeth0 192.168.16.0 global public ib0 172.16.0.0 global cluster_interconnect
“cluster_interconnect” — Private Interface in Oracle Clusterware
The iflist command queries the operating system to find which network interfaces are present on this node.
The command iflist shows the available interfaces that you can configure with “setif”.
-p parameter displays the type of interface which can be PRIVATE, PUBLIC or UNKNOWN
-n include the subnet mask
$ ./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
6) Network interface configuration
