Here i am going to post the steps needed to add a node to the existing two node RAC 11.2.0.3 Infrastructure on Oracle Virtual BOX
Already this is two node RAC Infrastructure configured on OEL6.5 on Oracle Virtual BOX.
I Have used backup to create additional node rac3.
During the Installation of 11.2.0.3 RAC on Virtual BOX before the configuration of ASM disks I have taken backup of Virtual BOX VM.
Please see my previous post
In the above post i have backed up the VM to some Backup location. To backup i have exported the present Appliance.
Backup VM. Click File export Appliance.
Now to Create a New RAC node, i have imported the appliance which was backed up earlier at the time installation of RAC.
Click on File->Import Appliance
If you dont have any backup. then need to configure a fresh vm and installation OEL6.5 with all pre-reqs steps which were mentioned in my previous post11gRACINSTALL
Select the backup file .ova path which was taken earlier.
Change the name to rac3 and scroll down to select the location where you want to save the imported VM.
RAC3 vm is going to get created once we import the appliance
Add ASMDISKS click on storage.
Click on the icon show in below screenshot
Click on Add Hard Disk
And select “choose existing disk”
Go to the ASM disk 1 and select it and click ok
Repeat this step for the remaining ASMDISKs*
Start the RAC3 VM
hostname has to be changed. Change it to rac3.
Save and exit.
Now we need to configure virtual nics with correct IP’s for Private and Public
Follow the navigation as below
Change the IP address from 192.168.56.71 to 192.168.56.73 this is for PUBLIC
Now change for Private also
Add the entries in /etc/hosts file as below
Install oracleasmlib rpm and configure ASM
in the above screenshot i have mistakenly provided group as dba(which should be oinstall).
Also install the missing RPM’s
also Configure SSH between all the 3 Nodes. I followed http://oracle-base.com/articles/linux/user-equivalence-configuration-on-linux.php
it has ssh setup for 2 Node rac
