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.
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 post.
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.
it has ssh setup for 2 Node rac
Manual User Equivalence (Key-Based Authentication) Configuration
Assuming we have a two node cluster (rac1.localdomain, rac2.localdomain), log in as the “oracle” user and perform the following tasks on each node.
su - oracle mkdir ~/.ssh chmod 700 ~/.ssh /usr/bin/ssh-keygen -t rsa # Accept the default settings.
The RSA public key is written to the ~/.ssh/id_rsa.pub file and the private key to the ~/.ssh/id_rsa file.
Log in as the “oracle” user on rac1.localdomain, generate an “authorized_keys” file and copy it to rac2.localdomainusing the following commands.
su - oracle cd ~/.ssh cat id_rsa.pub >> authorized_keys scp authorized_keys rac2.localdomain:/home/oracle/.ssh/
Next, log in as the “oracle” user on rac2.localdomain and perform the following commands.
su - oracle cd ~/.ssh cat id_rsa.pub >> authorized_keys scp authorized_keys rac1.localdomain:/home/oracle/.ssh/
The “authorized_keys” file on both servers now contains the public keys generated on all nodes.
To enable SSH user equivalency on the cluster member nodes issue the following commands on each node.
ssh rac1 date ssh rac2 date ssh rac1.localdomain date ssh rac2.localdomain date exec /usr/bin/ssh-agent $SHELL /usr/bin/ssh-add
But we need to work on configure ssh on 3 node rac for oracle user!!!
Copy hosts file from rac3 to the rest of the 2 servers rac1 and rac2.
Copy nslookup file from /usr/bin from rac1 to rac3cluvfy stage -pre nodeadd -n rac3 -fixup -verbose

Add Instance to Clustered Database
A database instance will be established on the new node. Specifically, an instance named “orcl3″ will be added to “orcl” – a pre-existing clustered database.
Satisfy Node Instance Dependencies
Satisfy all node instance dependencies, such as passwordfile, init.ora parameters, etc.
From the new node “rac3″, run the following commands to create the passwordfile, “init.ora” file, and “oratab” entry for the new instance[root@rac3 Desktop]# su - oracle [oracle@rac3 ~]$ export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1 [oracle@rac3 ~]$ cd $ORACLE_HOME/dbs [oracle@rac3 dbs]$ ls hc_orcl1.dat init.ora initorcl1.ora orapworcl1 [oracle@rac3 dbs]$ mv initorcl1.ora initorcl3.ora [oracle@rac3 dbs]$ mv orapworcl1 orapworcl3 [oracle@rac3 dbs]$ echo "orcl3:$ORACLE_HOME:N" >> /etc/oratab [oracle@rac3 dbs]$
From a node with an existing instance of “orcl” issue the following commands to create the needed public log thread, undo tablespace, and “init.ora” entries for the new instance

Update Oracle Cluster Registry (OCR)
The OCR will be updated to account for a new instance – “orcl3″ – being added to the “orcl” cluster database. Add “orcl3″ instance to the “orcl” database and verify
Start the Instance
Now that all the prerequisites have been satisfied and OCR updated, the “orcl3″ instance will be started. Start the newly created instance – “orcl3″ – and verify
