Modifikasi SCAN VIP address pada oracle 11g R2

--musabab--

documentasi from troublesome.......

--note--

scan menggunakan dns ( untuk settingan dns yang bagus menurut saya bisa mengacu ke sini )

--basic knowing--

yang perlu di perhatikan setelah editing adalah merefresh konfigurasi scan vip

--1--

cek konfigurasi awal

[oracle@cluster1 ~]$ srvctl config scan
SCAN name: cluster1-scan, Network: 1/12.168.1.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /12.168.1.2/12.168.1.2
SCAN VIP name: scan2, IP: /12.168.1.3/12.168.1.3
SCAN VIP name: scan3, IP: /11.168.1.1/11.168.1.1


--/kasus--

sekarang kita ingin merubah ip dari 11 ke 12

--2--

edit konfigurasi scan di DNS misal dalam grid.zone.nl( sesuaikan dengan settinga DNS masing 2)
cluster1-scan A 11.168.1.1
cluster1-scan A 12.168.1.2
cluster1-scan A 12.168.1.3

ubah menjadi :
cluster1-scan A 12.168.1.1
cluster1-scan A 12.168.1.2
cluster1-scan A 12.168.1.3

--3--


Restart DNS service

restart DNS service
[root@dns]# /etc/init.d/named restart
Reloading named: [ OK ]


--4--

tahapan terakhir adalah merefres settingan SCAN

[oracle@cluster1 ~]$ srvctl modify scan -n cluster1-scan

--cek n' jajal--

[root@cluster1 ~]# srvctl config scan
SCAN name: cluster1-scan, Network: 1/12.168.1.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /12.168.1.3/12.168.1.3
SCAN VIP name: scan2, IP: /12.168.1.1/12.168.1.1
SCAN VIP name: scan3, IP: /12.168.1.2/12.168.1.2
