Hello ,
1- Can you help me to understand SCAN IP's which use by ORACLE-BASE VMware installion :
Http://Www.Oracle-Base.Com/Articles/11g/Oracle-Db-11gr2-Rac-Installation-On-Oel5-Using-Virtualbox.Php#Create_Shared_Disks
It dose not clear for me why they use three different IP's
----------------------------------------
If you are not using DNS, the "/etc/hosts" file must contain the following information.
127.0.0.1 localhost.localdomain localhost
# Public
192.168.0.101 ol5-112-rac1.localdomain ol5-112-rac1
192.168.0.102 ol5-112-rac2.localdomain ol5-112-rac2
# Private
192.168.1.101 ol5-112-rac1-priv.localdomain ol5-112-rac1-priv
192.168.1.102 ol5-112-rac2-priv.localdomain ol5-112-rac2-priv
# Virtual
192.168.0.103 ol5-112-rac1-vip.localdomain ol5-112-rac1-vip
192.168.0.104 ol5-112-rac2-vip.localdomain ol5-112-rac2-vip
# SCAN
192.168.0.105 ol5-112-scan.localdomain ol5-112-scan
192.168.0.106 ol5-112-scan.localdomain ol5-112-scan
192.168.0.107 ol5-112-scan.localdomain ol5-112-scan

* My Q Is Round-Robin DNS Is Between Vip So Why They Use Different Ip Than Vip ? and must i put scan ip on /etc/hosts ?
2- Can I Install Oracle 11g.R2 Rac Without Using Scan Ip , If I Did Not Have DNS . I Just Put One Scan_Ip On /Etc/Hosts. So It Will Work Without Issue ?
And It Will Work As 11G.R1?
- i test to install oracle rac on vmware with one ip scan and it work without using Round-Robin DNS and without any configuration for scan ip . i just put it on /etc/hosts
3- Can anyone how to configure scan IP as Round-Robin DNS ?
Thanks.
