OracleRACネットワークおよびIP情報の確認

1.現在のスキャン構成を表示します

$ 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:

2.SCANDNSレコードに関する情報を取得します。

$ 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

ここで、192.168.16.41、192.168.16.42e192.168.16.43はSCANIPです

3.クラスター名を表示する

$./olsnodes -c
exadata-pclu1

4）PUBLICおよびVIPノード名を表示します。

$ 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）プライベートIP情報を表示する

$./olsnodes -n -i -l -p
exadatadm01vm011172.16.2.63exadata01vm01-vip

パブリックおよびプライベートネットワーク情報は、Oracle Cluster Registry（OCR）に格納されます。

$./oifcfg getif
bondeth0 192.168.16.0 global public
ib0 172.16.0.0 global cluster_interconnect

「cluster_interconnect」— OracleClusterwareのプライベート・インターフェース

iflistコマンドは、オペレーティングシステムにクエリを実行して、このノードに存在するネットワークインターフェイスを見つけます。
コマンドiflistは、「setif」で構成できる使用可能なインターフェイスを表示します。

-pパラメータは、PRIVATE、PUBLIC、またはUNKNOWNのインターフェイスのタイプを表示します
-nにはサブネットマスクが含まれます

$ ./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）ネットワークインターフェイスの構成

$ ifconfig |grep 192.168*
Ifconfig uses the ioctl access method to get the full address information, which limits hardware addresses to 8 bytes.
Because Infiniband address has 20 bytes, only the first 8 bytes are displayed correctly.
Ifconfig is obsolete! For replacement check ip.
