11gr2 Rac Install: Stuck at the DNS SCAN portion.

Xev BellringerJan 20 2014 — edited Feb 5 2014
  • Hi Guys, it's Xev.

Ok, I have followed his install guide to the dot. http://www.oracle-base.com/articles/11g/oracle-db-11gr2-rac-installation-on-oel5-using-virtualbox.php#install_grid_infrastructure

During the Grid Infrastructure install portion, it's stops me and tells me that "No Locally adapter is defined" when I am right here, it won't let me past this point right below...

Now, this install document, tells you to put the 3 SCAN Ip addresses in the /ect/hosts file and does not tell you that you need to install DNS on a server and configure it, or does he? The way he says it to

me just doesn't make sense.

My question is to only people that have actually installed 11gr2 RAC using VirtualBox and using oracle linux 5.8.

He says in the install document this right here, but some how i think he is just flat out wrong.

I quote from the install document,,,

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

Note. The SCAN address should not really be defined in the hosts file. Instead is should be defined on the DNS to round-robin between 3 addresses on the same subnet as the public IPs. For this installation, we will compromise and use the hosts file. This is not possible if you are using 11.2.0.2 onward.

If you are using DNS, then only the first line needs to be present in the "/etc/hosts" file. The other entries are defined in the DNS, as described here. Having said that, I typically include all but the SCAN addresses..

END QUOTE.

So, Guys, what does he actually mean with this? MY Grid install fails when it's trying to resolved the scan. DO I need to install DNS like he gives in the link above, OR can the install work with the SCAN in the /ect/hosts file? I Personally think this is just wrong, and you have to have DNS working 3 ip round-robin for the SCAN to work.

Please only reply to this thread if you have actually successfully installled 11rg2 Rac (11.0.1) on Oracle Linux 5.8 using VirtualBox, or actually know where i am going wrong by your own experience, not just goggle searching.....but you got it to work....

I am begging on my knees for help with this, since I have been at this for weeks now.

If you help me through this, I'll be your friend

Xev.
