$ 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. Dapatkan informasi tentang catatan 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
Dimana:192.168.16.41, 192.168.16.42 e 192.168.16.43 adalah IP SCAN
3. Tampilkan Nama Cluster
$./olsnodes -c exadata-pclu1
4) Menampilkan nama PUBLIC dan VIP Node.
$ 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) Menampilkan informasi IP Pribadi
$./olsnodes -n -i -l -p exadatadm01vm011172.16.2.63exadata01vm01-vip
Informasi jaringan publik dan pribadi disimpan di Oracle Cluster Registry (OCR).
$./oifcfg getif bondeth0 192.168.16.0 global public ib0 172.16.0.0 global cluster_interconnect
“cluster_interconnect” — Antarmuka Pribadi di Oracle Clusterware
Perintah iflist menanyakan sistem operasi untuk menemukan antarmuka jaringan mana yang ada pada node ini.
Perintah iflist menunjukkan antarmuka yang tersedia yang dapat Anda konfigurasikan dengan “setif”.
-p parameter menampilkan jenis antarmuka yang dapat PRIVATE, PUBLIC atau UNKNOWN
-n termasuk 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) Konfigurasi antarmuka jaringan
