Oracle 11gR2 RAC Installation on Oracle Linux 6.5
In this article we will be installing 2 node 11gR2 RAC on Oracle Linux 6.5. We will be looking at below steps:
Configure VM for Node 1
Open virtual box and create a new VM for node 1. We will be installing OEL 6.5 on both RAC nodes.
Create New VM
Open virtual box and click on New. Create first virtual machine with oraracn1 as the name.
Min RAM allocation should be 4 GB per RAC node.
Create a virtual disk now
Select VDI and click next
Select Dynamically allocated option and click next
Allocate Min 80 GB HDD to your virtual machine. You can allocate even more if you have good hard disk space. Click on Create
Now your virtual machine should be created. This is how your virtual box will look like
Right click on virtual machine and select settings. Under System settings, make sure to set below bootorder
Under storage > Optical Drive > choose OEL 6.5 iso file from your system.
Under Network, make sure attached to is set to Bridged Adapter and Enable the Network Adapter
In RAC, we need to have two network adapters. So, enable the second adapter same like the first one.
Click on OK to complete the RAC node 1 setup.
Install OEL 6.5 on Node 1
Now that our virtual machine is ready, go ahead, start the virtual machine and install OEL 6.5

OS Prerequisites – All Nodes
Connect to both RAC nodes via putty and execute all the below commands on both nodes.
Check if your machine is able to speak to internet. You can ping yahoo.com. Then install below package to perform all oracle installation pre-requisites
yum -y install oracle-rdbms*
Install ASM packages
yum -y install oracleasm*
yum -y install kmod-oracleasm
Change password for oracle user
passwd oracle
Disable firewall
/etc/rc.d/init.d/iptables status
/etc/rc.d/init.d/iptables stop
service iptables stop
chkconfig iptables off
echo 0 > /selinux/enforce
Create directories to install grid and oracle software
mkdir -p /u01/app/11.2.0/grid mkdir -p /u01/app/oracle/product/11.2.0/db_1 chown -R oracle:oinstall /u01 chmod -R 775 /u01/
mkdir -p /u02
chown -R oracle:oinstall /u02
Download Oracle 11.2.0.4 gird and database binaries. Copy it to /u02 location (Only on Node 1)
Setup Public & Private Network
We have below public and private network configuration for our RAC setup:
Also, below are the Virtual IP and Scan IP details:
Depending upon your environment, change IP addresses and put below under /etc/hosts file on both oraracn1 and oraracn2 nodes
On both nodes:
==============
127.0.0.1 localhost.localdomain localhost
# Public Network - (eth0)
192.168.0.101 oraracn1.oraclegenesis.com oraracn1
192.168.0.102 oraracn2.oraclegenesis.com oraracn2
# Private Interconnect - (eth1)
10.10.10.101 oraracn1-priv.oraclegenesis.com oraracn1-priv
10.10.10.102 oraracn2-priv.oraclegenesis.com oraracn2-priv
# Public Virtual IP (VIP) addresses - (eth0:1)
192.168.0.105 oraracn1-vip.oraclegenesis.com oraracn1-vip
192.168.0.106 oraracn2-vip.oraclegenesis.com oraracn2-vip
# Single Client Access Name (SCAN)
192.168.0.110 orarac-scan.oraclegenesis.com orarac-scan
Test the network configuration
On oraracn1:
============
# ping oraracn1 --> use Ctrl+C to exit from ping
# ping oraracn2
# ping oraracn1-priv
# ping oraracn2-priv
On oraracn2:
============
# ping oraracn1 --> use Ctrl+C to exit from ping
# ping oraracn2
# ping oraracn1-priv
# ping oraracn2-priv
Note: You cannot ping VIP and SCAN IP. Those IPs can only be used by an application and are not ping-able!
Configure Shared Storage
At this stage, shutdown both the virtual machines. We will allocate shared disks to RAC nodes. Open oraracn1 virtual machine settings and select storage. Click on Adds Hard Disk button under SATA controller
Choose Create new disk
Choose VDI and click Next
Select Fixed size and click Next
Allocate 100 GB of shared storage to your RAC setup
This will take some time to add shared disk to Node 1
Once disk is added, you can see the disk under Node 1 settings > storage
Now our goal is to make newly added disk on node 1 shared with node 2. For this, go to File > Virtual Media Manager
Select your shared disk > right click > choose Modify
Change the property from Normal to Shareable and click on OK
Now we are ready to share the disk with Node 2. Open oraracn2 settings > Storage > Adds hard disk icon
Do not create a new disk, Choose existing disk
Locate your shared disk at OS level. It must mostly be stored under your Node 1 location
The disk must now be shared with node 2 as well. You will see the RAC Shared Storage below
Create Shared Partitions
Now that we have 100 GB of shared storage, we need to create three partitions for the main three ASM disk groups
Create three partitions under the newly added 100 GB shared disk via node 1
On Node 1:
==========
fdisk /dev/sdb
n
p
1
<enter>
+10G
============ Frist partition is created, create second one ============
n
p
1
<enter>
+45G
============ Second partition is created, create third one =============
n
p
1
<enter>
+45G
======= All partitions are created, now save the partition table ==========
w this command will save the partition table
Configure ASM & ASM Disks
As we have created 3 partitions, we must allocate each partition to single ASM disks, which will then be allocated to ASM Disk groups
Configure ASM on both nodes
On Node 1 as root user:
=======================
/usr/sbin/oracleasm configure -i
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
On Node 2 as root user:
=======================
/usr/sbin/oracleasm configure -i
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Load oracle-asm kernel module on both nodes. This command Creates the /etc/sysconfig/oracleasm configuration file, creates the /dev/oracleasm mount point and mounts the ASMLib driver file system
On Node 1 as root user:
=======================
/usr/sbin/oracleasm init
On Node 2 as root user:
=======================
/usr/sbin/oracleasm init
Create ASM disks – Any one Node
On Node 1 as root user:
=======================
oracleasm createdisk CRS1 /dev/sdb5
oracleasm createdisk DATA1 /dev/sdb6
oracleasm createdisk FRA1 /dev/sdb7
Run below commands on both nodes to scan and list ASM disks
oracleasm scandisks
oracleasm listdisks
Oracle Grid Installation
Oracle grid software is the one which binds multiple independent servers into a cluster. You can configure ASM only when Oracle grid is installed because ASM is bundled with Oracle Grid Software.
Configure NTP – All Nodes
On Node 1 and Node 2:
=====================
# yum install ntp
# service ntpd start
# chkconfig ntpd on
# vi /etc/sysconfig/ntpd -> Open file delete all and put below line
OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid -g"
# service ntpd stop
# ntpdate 1.tw.pool.ntp.org
# service ntpd start
Now its good time to clean-up the YUM repository to release some space from the disk
On both nodes as root user:
===========================
# yum clean all
Set Bash Profile
Setup oracle user bash profile on node 1
# su - oracle
# vi .bash_profile
# Oracle Settings

alias grid_env='. /home/oracle/grid_env'
alias db_env='. /home/oracle/db_env'
Create a file to set grid variables on node 1. This file will set grid environmental variables making it easy to switch between DB home and grid home.
# vi /home/oracle/grid_env
ORACLE_SID=+ASM1; export ORACLE_SID
ORACLE_HOME=$GRID_HOME; export ORACLE_HOME

alias grid_env='. /home/oracle/grid_env'
alias db_env='. /home/oracle/db_env'
Create a file to set grid variables on node 2. This file will set grid environmental variables making it easy to switch between DB home and grid home.
# vi /home/oracle/grid_env
ORACLE_SID=+ASM2; export ORACLE_SID
ORACLE_HOME=$GRID_HOME; export ORACLE_HOME

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPAT H
At this stage, exit as oracle user and the open another terminal with new session OR switch to root user and then back to oracle user. This will make the new environmental variables in effect.
Now it’s time to test our environment variables and check if they are working fine or not. As oracle user, execute below commands on both nodes to check if environmental variables are set properly
Node 1:
-------
su – oracle
# . grid_env --To set grid env variables
# env |grep ORA
ORACLE_UNQNAME=RAC
ORACLE_SID=+ASM1
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=oraracn1
ORACLE_TERM=xterm
ORACLE_HOME=/u01/app/11.2.0/grid
# . db_env --To set DB env variables
# env |grep ORA
ORACLE_UNQNAME=RAC
ORACLE_SID=RAC1
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=oraracn1
ORACLE_TERM=xterm
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
Node 2:
-------
su – oracle
# . grid_env --To set grid env variables
# env |grep ORA
ORACLE_UNQNAME=RAC
ORACLE_SID=+ASM2
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=oraracn2
ORACLE_TERM=xterm
ORACLE_HOME=/u01/app/11.2.0/grid
# . db_env --To set DB env variables
# env |grep ORA
ORACLE_UNQNAME=RAC
ORACLE_SID=RAC2
ORACLE_BASE=/u01/app/oracle
ORACLE_HOSTNAME=oraracn2
ORACLE_TERM=xterm
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
Configure SSH Between Nodes
Configure SSH connectivity between the nodes as oracle user. There are two methods to setup SSH connectivity between the nodes is: Manual method and automatic method. The manual method is very long and you might encounter errors while doing it. The easy way is the automatic method via script provided by oracle.
As you have already copied the grid and database software files under /u02, unzip the grid software file. This will create a new folder name grid under /u02. Oracle provides automatic ssh setup script
On node 1 as oracle user:
=========================
cd /u02
unzip <grid_software_file_name>
cd grid/sshsetup
./sshUserSetup.sh -user oracle -hosts "oraracn1 oraracn2" -noPromptPassphrase -confir m -advanced
Run cluvfy utility
Oracle provide a pre-installation utility which is called as Cluster Verification Utility (CLUVFY). This utility performs cluster verification before, during and after install of grid software. Let us run CLUVFY utility to check cluster before installation of grid
# /u01/softwares/grid
# ./runcluvfy.sh stage -pre crsinst -n oraracn1,oraracn2 -fixup -verbose
Below is the sample output:
[oracle@oraracn1 grid]$ ./runcluvfy.sh stage -pre crsinst -n oraracn1,oraracn2 -fixup -verbose

Install Grid Software
The following steps will guide you to install Oracle Grid software with Oracle ASM binaries. As oracle user, start the grid runInstaller
On Node 1:
==========
su – oracle
# cd /u02/grid/
# ./runInstaller
Note: sometimes there might be display variable error. issues below command as root user to enable GUI
# xhost +
Under Select Installation Option, choose Install and Configure Grid Infrastructure for a Cluster and Click Next
Select Advanced Installation and click Next
Select Advanced Installation and click Next
Input below details and click Next
Below screen will list out the nodes which you want to install and configure as part of Grid
Click on Add and enter details of Node 2. Click on OK
In case you have more than two nodes, Add each node by clicking on Add. Click Next to proceed
Specify network interface by selecting public and private interfaces. Click Next
Select storage option as Automatic Storage Management (ASM). Click Next
You need to assign a disk where the grid installer will keep OCR and Voting disks. Click on Change Discovery Path, type /dev/oracleasm/disks/* and click OK. Under Add Disks, you must see the three disks which we have created as part of Shard Storage.
Before you proceed, sometimes you might not see the lists of disks. In such cases, follow below:
1. Check if /dev/sdb1, /dev/sdc1, /dev/sdd1 had ownership as oracle user. If not then issue below commands as root user on both nodes:
# chown oracle:oinstall /dev/sdb1
# chown oracle:oinstall /dev/sdc1
# chown oracle:oinstall /dev/sdd1
2. Also give full permissions on above disks
# chmod 777 /dev/sdb1
# chmod 777 /dev/sdc1
# chmod 777 /dev/sdd1
Again go to Change Discovery Path, type /dev/oracleasm/disks/* and click OK. Now all the disks will be listed. Type Disk Group Name as CRS, Redundancy as External and under Disk Path /dev/oracleasm/disks/CRSVOL1
Now provide password for sys user and click Next
It will prompt you for password standard, just click on Yes
Select Do Not Use IPMI and click Next
Go with default operating system groups and click Next. If prompted with notification, just click on Yes
Provide Oracle Base and Software Installation Location. Click on Next
Go with default inventory location. Click Next
The run Installer will perform pre-requsites test again. If any step is failed, you must fix it before proceeding ahead
The final screen displays installation summary. Important things to note here:
Oracle Base Location
Oracle Home – This should actually be grid home
Click on Finish to start the installation
Now the setup will start installing Grid Software on both nodes
Now the installer will prompt you for two root.sh scripts to be run on each node. Execute them as root user on both nodes one by one.
Your grid installation will finish and Cluster Verification Utility Filed error will be displayed. Just ignore the error.
Oracle RAC Installation
During the installation of Oracle grid infrastructure, we configured one ASM disk group named +CRS which was used to store the Oracle clusterware files (OCR and voting disk). Now we will configure ASM disk groups for DATA and FRA
Create DATA & FRA Diskgroups
Launch asmca form the command prompt as oracle user
On node 1:
==========
su – oracle
asmca
ASM Configuration Assistant window will launch. From the Disk Groups tab, click on Create.
The Create Disk Group window will open and it should show two of the ASMLib volumes we created earlier
Click on Create. Give a name to your DATA disk group. This disk group will hold database files. Then click on OK
Install Oracle RAC Software – Node 1 only
Unzip the database software files under /u02. There will be two files downloaded. Unzip them as oracle user one by one
# su - oracle
# cd /u02
# unzip linux.x64_11gR2_database_1of2.zip
# unzip linux.x64_11gR2_database_2of2.zip
Unzipping files will create a new folder as database under same location
# ls -lrt
drwxr-xr-x 8 oracle oinstall 4096 Aug 21 2009 database
-rwxr-xr-x 1 oracle oinstall 1052897657 Nov 2 09:41 linux.x64_11gR2_grid.zip
-rwxr-xr-x 1 oracle oinstall 1239269270 Dec 1 01:00 linux.x64_11gR2_database_1of2.zip
-rwxr-xr-x 1 oracle oinstall 1111416131 Dec 1 01:01 linux.x64_11gR2_database_2of2.zip
Go to database folder and start the runInstaller
# cd database
# ./runInstaller
Create RAC Database
From node 1, start dbca as oracle user
On node 1:
==========
su - oracle
dbca
Done! Your 2 node RAC database is ready to use!
