1. Afficher la configuration d'analyse actuelle
$ 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. Obtenez des informations sur les enregistrements DNS SCAN.
$ 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
Où :192.168.16.41, 192.168.16.42 et 192.168.16.43 sont les IP SCAN
3. Afficher le nom du cluster
$./olsnodes -c exadata-pclu1
4) Affichez le nom du nœud PUBLIC et VIP.
$ 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: VIP exists: network number 1, hosting node exadatadm02vm01 VIP Name: exadata02vm01-vip VIP IPv4 Address: 192.168.16.47 VIP IPv6 Address: VIP is enabled. VIP is individually enabled on nodes: VIP is individually disabled on nodes:
5) Afficher les informations IP privées
$./olsnodes -n -i -l -p exadatadm01vm011172.16.2.63exadata01vm01-vip
Les informations sur les réseaux publics et privés sont stockées dans Oracle Cluster Registry (OCR).
$./oifcfg getif bondeth0 192.168.16.0 global public ib0 172.16.0.0 global cluster_interconnect
"cluster_interconnect" - Interface privée dans Oracle Clusterware
La commande iflist interroge le système d'exploitation pour trouver quelles interfaces réseau sont présentes sur ce nœud.
La commande iflist affiche les interfaces disponibles que vous pouvez configurer avec "setif".
Le paramètre -p affiche le type d'interface qui peut être PRIVATE, PUBLIC ou UNKNOWN
-n inclut le masque de sous-réseau
$ ./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) Configuration de l'interface réseau
$ ifconfig |grep 192.168* Ifconfig uses the ioctl access method to get the full address information, which limits hardware addresses to 8 bytes.
