Step by Step installing Oracle 10g RAC
on VMware
Posted by Kamran Agayev A. on April 5, 2011
In this guide I’m going to show you the process of creating Oracle 10g R2 RAC on OEL4. First of all I have to mention that I’ve prepared this guide based on the well known RAC on VMWare guide of for Vincent Chan which can be found at OTN. After using that guide I’ve decided to create a more screenshot based explained guide and prepared this blog post which contains 150 screenshots!
These days wordpress.com is working veeeeery slowly, so it took me two days to upload all images and create this blog post That was really boring. But now the blog post is online and I would be glad to hear the visitors valuable feedbacks.
In this tutorial, we use OEL4 because Oracle 10gR2 is not compatible with OEL5 (as the db was released before the OS released) As in my all tutorials, I use vmware virtual machine. In this guide I will create two virtual machines. Let’s start creating the first machine. But before it, create three directories inside one folder (for example c:\vmware)
1C:\vmware\rac1
2
3C:\vmware\rac2
4
5C:\vmware\sharedstorage
Create the following virtual machine in the first folder and create all shared storages in the third folder
Click Next
Select Typical and click Next
Select “Red Hat Enterprise Linux 4” and Click Next
Provide the name of the virtual machine (rac1), select the location for vmware disk (you can make it c:\vmware\rac1) and click Next
Select bridged network and click next
Define the size of the hard drive of the virtual machine and click Next (set it to 20 GB and don’t check “Allocate all disk space now” checkbox)
Mount the ISO image of the OEL4 installation and start adding more four hard drives and one Ethernet device. Click on Add button
Select “Hard Disk” and click Next
Select “Create a new virtual disk” and click Next
Select “SCSI” and check “Independent->Persistent” and click Next
For the first device, specify the disk size as “3gb”, check “Allocate all disk space now” and click Next
Create a separate folder named “C:\vmware\sharedstorage” in your hard drive, set the name of the new hard drive to “ocfs2disk.vmdk”.
After creating the first device, create more three devices with 4GB in size (asmdisk1.vmdk, asmdisk2.vmdk, asmdisk3.vmdk) and make all of them “Independent->Persistent” and don’t allocate the disk space for each of them
Next, start changing the device node for each of them. Start from the firstly added hard drive, select it, click on Advanced button and make it SCSI 1:0. For next hard drive make it 1:1 and so on
Add new Ethernet device
Change the network connection to “Host-only”
Make sure that the last state of your virtual machine looks like as it’s seen above
Then locate the configuration file of the virtual machine and start editing it
Add the lines that are marked in bold to the configuration file to make the devices be shared between to nodes
- By specifying “disk.locking” to FALSE will allow any virtual machine to load a SCSI disk device even it’s in use by an another virtual machine
- Specify “diskLib.dataCacheMaxSize = “0″ to turn off the disk caching for clustered virtual machines.
- By specifying scsi1.sharedBus = “virtual” will give the whole bus the ability to be shared. This prevents the locking of this specific disk
Start the virtual machine
As you have already mounted the ISO image of the OEL4, the above screen appears
Select installation language and click next
Select appropriate keyboard and click next
Select “Server” as the installation type and click Next
Select Disk Druid for disk partitioning method and click Next
Click Yes for all warnings and click Next
Double click in the first drive /dev/sda
Specify ‘/’ as a mount point, make its files system “ext3” and make the End Cylinder 900 (to make the size of the root folder 7Gb). Check “Force to be a primary partition” and click Ok
Select File System Type as “swap” and change End Cylinder to 1170
Create mount point called /u01, make its files system “ext3” and make End Cylinder 2610 and click Ok
Make sure that the last state of your disk partitioning looks like as it’s seen above
Now let’s configure the network devices. Select the first device and click Edit
Uncheck “Configure using DHCP” and provide the following ip address and netmask:
IP Address: 192.168.2.131
Netmask: 255.255.255.0
Select the second device, edit it, uncheck “Configure using DHCP” and provide the following ip address and netmask
IP address: 10.10.10.31
Netmask: 255.255.255.0
Set the hostname as “rac1.test.az” (you can provide any domain name) and set the gateway to 192.168.2.1
Disable Firewall and SELinux and click Next
Select the default language for the system and click Next
Select Time-Zone and Click Next
Provide the password for the root user and click next
Select necessary packages for Oracle installation. Here’s the list of the necessary packages:
X Window System
Gnome Desktop Environment
Editors
Graphical Internet
Server Configuration Tools
Legacy Network (click Details and select “rsh_server” and “telnet-server”)
Development Tools
Legacy Software Development
Administration Tools
System Tools (select all packages that starts with “ocfs2” and “oracleasm”, select “systat” as well)
Click Next to start the installation
After installation completed the machine restarts. Click Next
Agree with license and click Next
Set the date and time and click Next
Set the display and click Next
You don’t need to create a user so click Next
Click Next and finish the installation
Now let’s install vmware tools. For this, disconnect the mounted ISO image, choose “Install VMware Tools” from VM menu
Double click on VMware tools icon and run the .rpm file by double clicking on it
After the window is closed, open new terminal and run vmware-config-tools.pl and finish the installation of vmware tools
To synchronize the time on the virtual machine with the host machine execute “vmware-toolbox” on the terminal window and check the check box
Edit /boot/grub/grub.conf file and add “clock=pit nosmp noapic nolapic” to the line that reads kernel /boot
The “clock=pit” prevents the clock for running to quickly and “nosmp noapic nolapic” prevents the clock from running too slowly. After you make the change, reboot the machine for change to take effect
Now let’s start the prerequisite steps for Oracle installation. For this we’ll create a group, a user and some directories
view source
print ?
0 groupadd
1 oinstall0203
groupadd dba
0405
mkdir -p /export/home/oracle
0607
mkdir /ocfs
0809
useradd -d /export/home/oracle -g oinstall -G dba oracle
1011
chown oracle:dba /export/home/oracle /u01
1213
passwd oracle
Change the .bash_profile (and .bashrc) file and add the following lines:
view source
print ?
0 export
1 EDITOR=vi0203
export ORACLE_SID=devdb1
0405
export ORACLE_BASE=/u01/app/oracle
06
07
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
08
09
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
10
11
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
12
13
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
1415
umask 022
Now switch to oracle user with “su – oracle” command. Make sure all environment variables are set (echo $ORACLE_HOME). After that, create the following directories:
view source
print ?
1 su - oracle2
3mkdir -p $ORACLE_BASE/admin
4
5mkdir -p $ORACLE_HOME
6
7mkdir -p $ORA_CRS_HOME
8
9mkdir -p /u01/oradata/devdb
Note that if environment variables are not set correctly, then the above mentioned directories will not be created.
Change /etc/security/limits.conf file with a root user and add following lines:
view source
print ?
1 oracle soft nproc
20472
3oracle hard nproc 16384
45 oracle soft nofile 10246
7oracle hard nofile 65536
Change /etc/pam.d/login file and add the following line:
view source
print ?
1 session required /lib/security/pam_limits.so
Now mount the third installation cd of the OEL4, connect it and open new terminal. Switch to the RPMS folder inside the cd and install “libaio-0.3.105-2.i386.rpm” and “openmotif21-2.1.30-11.RHEL4.6.i386.rpm” packages
view source
print ?
1rpm –Uvh libaio-0.3.105-2.i386.rpm
2
3rpm –Uvh openmotif21-2.1.30-11.RHEL4.6.i386.rpm
Change /etc/sysctl.conf file and add the following lines:
view source
print ?
01
kernel.shmall = 2097152
0203
kernel.shmmax = 2147483648
0405
kernel.shmmni = 4096
0607
kernel.sem = 250 32000 100 128
0809
fs.file-max = 65536
1011
net.ipv4.ip_local_port_range = 1024 65000
1213
net.core.rmem_default = 1048576
1415
net.core.rmem_max = 1048576
1617
net.core.wmem_default = 262144
181 net.core.wmem_max =
9 262144
Then execute the following command for change to take effect:
/sbin/sysctl -p
Now let’s configure the network configuration files. For this we need to add IP addresses and hostnames to the /etc/hosts file in each node and test the connection by pinging the hostnames
view source
print ?
01
127.0.0.1 localhost
0203
192.168.2.131 rac1.test.az rac1
0405
192.168.2.31 rac1-vip.test.az rac1-vip
0607
10.10.10.31 rac1-priv.test.az rac1-priv
0809
192.168.2.132 rac2.test.az rac2
1011
192.168.2.32 rac2-vip.test.az rac2-vip
1213
10.10.10.32 rac2-priv.test.az rac2-priv
Try the connection by pinging all hostnames (don’t ping VIP addresses as they will be created during clusterware installation):
ping rac1.test.az
ping rac1-priv.test.az
and son on
Now start creating disk partitions for OCFS2 and ASM. /dev/sdb will be used for OCFS2 and rest devices will be used for ASM.
fdisk /dev/sdb
Type n (to create new partition)
Type p to create a primary partition
Type 1 to provide the partition number
Double click on Enter and type “w” to save the changes
Perform above steps for all hard disk:
fdisk /dev/sdc
fdisk /dev/sdd
fdisk /dev/sde
To map the raw devices to the shared partitions, change /etc/sysconfig/rawdevices file:
view source
print ?
1 /dev/raw/raw1
/dev/sdc12
3/dev/raw/raw2 /dev/sdd1
4
5/dev/raw/raw3 /dev/sde1
And run the following command to make it effective
/sbin/service rawdevices restart
Then change the permission for all newly created raw devices:
view source
print ?
1chown oracle:dba /dev/raw/raw[1-3]
2
3chmod 660 /dev/raw/raw[1-3]
45 ls -lat /dev/raw/raw*
Next, switch to the oracle user and create links for raw devices
view source
print ?
1 su - oracle2
3ln -sf /dev/raw/raw1 /u01/oradata/devdb/asmdisk1
4
5ln -sf /dev/raw/raw2 /u01/oradata/devdb/asmdisk2
6
7ln -sf /dev/raw/raw3 /u01/oradata/devdb/asmdisk3
As the raw devices are remapped on boot, change /etc/udev/permissions.d/50-udev.permissions with the root user and add the following lines:
view source
print ?
1# raw devices
2
3ram*:root:disk:0660
4
5#raw/*:root:disk:0660
6
7raw/*:oracle:dba:0660
After performing all above steps, shutdown the virtual machine. Then copy all its files to another directory (c:\vmware\rac2)
Open it, switch to the Options tab, change its name to “rac2” and start it
Open Network Configuration and change addresses of each Ethernet device.
eth0 – 192.168.2.132
eth1 – 10.10.10.32
Then from Hardware Device type click on “Probe” button to get new MAC address, enable both network devices, change hostname to rac2.test.az and click Ctrl+S to save the changes. Then add the following line to the /etc/hosts file
127.0.0.1 localhost
Now it’s time to establish user equivalence with SSH. Oracle Universal Installer installs the binaries in one node and then propagates the files to the other nodes. For this, it uses ssh and scp command in the background during installation to run remote commands and copy files to the other cluster nodes. So SSH must be configured so that these commands not prompt for a password. For this power on the first machine, login with root user, switch to the oracle user and generate RSA and DSA key pairs
su – oracle
ssh-keygen –t rsa (click Enter twice)
ssh-keygen –t dsa (click Enter twice)
Perform above steps in the second node (rac2)
Now (from rac1) add the generated keys to the ~/.ssh/authorized_keys file
view source
print ?
1 cat ~/.ssh/id_rsa.pub >>
~/.ssh/authorized_keys2
3cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
Then from rac1 SSH to rac2 twice and add the .rsa and .dsa keys to the “authorized_keys” file that locates in the first node:
view source
print ?
1ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
2
3ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
Now copy the “authorized_keys” file from rac1 to rac2:
view source
print ?
1scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys
After performing all above steps, you should successfully open SSH connection from rac1 to rac2 and vice verse. So run the following commands in both nodes and ensure that you’re not prompted for the password for the second time:
view source
print ?
01
ssh rac1 date
0203
ssh rac2 date
0405
ssh rac1-priv date
0607
ssh rac2-priv date
0809
ssh rac1.test.az date
1011
ssh rac2.test.az date
1213
ssh rac1-priv.test.az date
1415
ssh rac2-priv.test.az date
I want to note again “Please make sure that after running above commands on each node, you’re not prompted for the password for the second time”
Now let’s configure Oracle ASM (Automatic Storage Management). So run the following commands from both nodes with root user:
/etc/init.d/oracleasm configure
Pass “oracle” as a parameter for “default user”
Pass “dba” as a parameter for “default group”
Pass “y” for the third and fourth parameters
Then create ASM disks on any node (try on the first node – rac1) with a root user:
/etc/init.d/oracleasm createdisk VOL1 /dev/sdc1
Marking disk “/dev/sdc1″ as an ASM disk: [ OK ]
/etc/init.d/oracleasm createdisk VOL2 /dev/sdd1
Marking disk “/dev/sdd1″ as an ASM disk: [ OK ]
/etc/init.d/oracleasm createdisk VOL3 /dev/sde1
Marking disk “/dev/sde1″ as an ASM disk: [ OK ]
Verify that the ASM disks are visible from every node.
/etc/init.d/oracleasm scandisks
Scanning system for ASM disks: [ OK ]
/etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3
Now let’s configure Oracle Cluster File System (OCFS2). For this, run “ocfs2console” with a root user from the first node. Then from the Cluster menu select Configure Nodes, click Add button and apply both nodes:
rac1
192.168.2.131
7777
rac2
192.168.2.132
7777
Then propagate the configuration to the second node. For this select “Propagate Configuration” from the Cluster menu.
To configure O2CB to start at the boot unload and configure it on both nodes as a root user:
/etc/init.d/o2cb unload
/etc/init.d/o2cb configure
and pass the following parameters
“y”
ocfs2
61
Now format the file system on the first node (rac1). For this run ocfs2console program, select Format from the Tasks menu and click OK to format the drive. Press Ctrl+Q to quit
Now execute the following command on both nodes to mount the files system
mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs
and add the following line to the /etc/fstab to mount the files system on boot
/dev/sdb1 /ocfs ocfs2 _netdev,datavolume,nointr 0 0
Create a “clusterware” directory under /ocfs folder and change the owner:
view source
print ?
1mkdir /ocfs/clusterware
2
3chown -R oracle:dba /ocfs
Now to test the shared device, create a file in the /ocfs directory from the first node (rac1) and check the same folder in the second node.
cd /ocfs
touch test_file
ls
Now download the clusterware installation, copy it under /tmp directory, unzip it and start the installation
./runInstaller
Provide the folder for the Inventory and click Next
Create a “clusterware” directory under /ocfs folder and change the owner:
view source
print ?
1 mkdir /ocfs/clusterware</span></p>
2<p class="MsoNormal" style="margin: 0 0 10pt;"><span style="font-family: Calibri; font-size: small;">chown -R oracle:dba /ocfs
Now to test the shared device, create a file in the /ocfs directory from the first node (rac1) and check the same folder in the second node.
cd /ocfs
touch test_file
ls
Now download the clusterware installation, copy it under /tmp directory, unzip it and start the installation
./runInstaller
Provide the folder for the Inventory and click Next
Change the CRS folder to /u01/app/oracle/product/10.2.0/crs_1 and click Next
After checking all prerequisites it should not give any warning, so click Next
Click on Add button and provide the information on the second node:
Public Node Name: rac2.test.az
Private Node Name: rac2-priv.test.az
Virtual Host Name : rac2-vip.test.az
Click on Edit button, change the Interface type of the first Ethernet device (eth0) to “Public” and the second to “Private”
Select External Redundancy and provide the location for OCR :
/ocfs/clusterware/ocr
Select External Redundancy and provide the location for Voting Disk
/ocfs/clusterware/votingdisk
Now click Install button to start the clusterware installation
After installation completes, run both scripts on both nodes
Run /u01/app/oracle/oraInventory/orainstRoot.sh on rac1 and rac2 (wait each script to complete before running it on the second node)
Run /u01/app/oracle/product/10.2.0/crs_1/root.sh on rac1 and rac2 (wait each script to complete before running it on the second node)
After running the second script on the second node (rac2) you’ll get an error (on running VIPCA), so you need to run it manually. Switch to the following directory
cd /u01/app/oracle/product/10.2.0/crs_1/bin
and run the ./vipca to create and configure VIP
Select the first Ethernet device and Click Next
After running the second script on the second node (rac2) you’ll get an error (on running VIPCA), so you need to run it manually. Switch to the following directory
cd /u01/app/oracle/product/10.2.0/crs_1/bin
and run the ./vipca to create and configure VIP
Select the first Ethernet device and Click Next
Type “rac1-vip” on the IP Alias Name for the first node (rac1). The rest boxes will be filled automatically. Click Next
Click Finish to start the installation
After vipca finished successfully, switch to the first node and click OK button on the “script running” window.
Click Exit button to exit the installation of an Oracle Clusterware
Now copy the installation of the database (Oracle 10gR2) to the /tmp directory, unzip and start the installation. You need to start the installation with an oracle user, so run “xhost +” from the root user to allow the connection to the X server and switch to the oracle user
xhost +
su – oracle
./runInstaller
Select “Enterprise Edition” and click Next
Provide the installation directory (/u01/app/oracle/product/10.2.0/db_1)
Select both nodes and click Next
The prerequisite check should be successful, so click Next
Let’s install just a software, so check “Install database Software only” and click Next
Click Install to start the installation
Execute the mentioned script on both nodes (wait for the script to finish before running it on the second node)
After installation finishes, run “dbca” (Database Configuration Assistant), select “Oracle Real Application Clusters database” and click Next
Select “Configure Automatic Storage Management” and click Next
Select both nodes and click Next
Provide the password for an ASM instance, select “Create initialization parameter file (IFILE)” and click Next
Click OK to create and ASM instance on both nodes
Click YES to create listener on both nodes
Now let’s create an ASM disks. For this, click “Create New” button
Provide the name of the diskgroup “dg1”, select the “External” redundancy, select two disks “raw1,raw2” and click OK
The disk group will not be mounted in the second node, so omit this warning. The second node should be restarted (but not now)
Create the second disk group for flash recovery area (fg), select an “External” redundancy, select the last device (raw3) and click Ok
As you see, the state of disk group shows that it’s not mounted on the second node. For this, we need to restart the second node. Click on Finish and restart the second node. After it starts, login with root user and call dbca from the first node again.
Move to the above window again and you’ll see that the disk group is mounted on both nodes. Click on Finish button
Run dbca again and select “Create a Database”
Select both nodes and click Next
Select “General Purpose” and click Next
Provide the database name “devdb” and click Next
Uncheck “Configure the Database with Enterprise Manager” as it’s taking too much (some hours) to finish (however, if you have enough RAM, you can check it) and click Next
Provide the password for the SYS user and click Next
Select “Automatic Storage Management” and click Next
Provide the password for ASM and click OK
Select the first disk group and click Next
Select “Use Oracle-Managed Files” and click Next
Check “Specify Flash Recovery Area” and chose “FG” disk group and click Next
Click Next (We’ll create TAF afterwards)
Click Finish to start the installation
After some hours (as I was running each virtual machine with 1GB RAM) this screen appears. Click Exit
Now both instances will be started.
After all, check the status of the Clusterware. As you see, some applications are with “OFFLINE” state. To make them online, stop and start them with SRVCTL utility as it’s shown above
After all, check the CRS status again. As you see, the State column of all applications are ONLINE
Now connect to the database from the first node (rac1) and run the following query
SQL>col host_name format a20
SQL>SELECT instance_name, host_name, thread#, status from gv$instance;
Try the conection to both instances:

Now let’s create a Service. Services are used to manage the workload in an RAC environment and provide high availability. To create the service run “dbca”
Select the first option and click Next
Select “Service Management” and click Next
Select the first database and click Next
Provide the name of the Service and click Next
When you specify PREFERRED instances, you are specifying the number of instances on which a service will normally run. The Oracle Clusterware attempts to ensure that the service always runs on the number of nodes for which you have configured the service. Afterwards, due to either instance failure or planned service relocations, a service may be running on an AVAILABLE instance
Select Preferred for the first instance, and Available for the second instance, change the TAF policy to Basic and click Finish
After the Service created automatically, check tnsnames.ora file and you’ll see that the new entry is added

Try to connect to the database using this service. As you see, we’ll automatically connect to the first instance. Now let’s check the RAC high availability
For this, while connecting to the first instance (devdb1) using a “service”, open new terminal, connect to the first instance and shut it down
Now go back to the first session and query the v$instance view again. As you see, you’ll be automatically forwarded to the second instance
In this step by step tutorial I’ve shown you the deep step by step guide using 150 screenshots to make the RAC installation easier for you. I hope you’ll successfully install RAC and make your own tests. Good Luck!

Dear Kamran,How I can check that my OLE 4.8 vmware is sharing disks.
I have fallowed the steps carefully but my OCFS2 disk not mount at second node, I can’t see it on second node after mounting it successfully on node1 (server of ocfs)
I check /etc/ocfs2/cluster.conf that is properly formatted and when I check status of o2cb it shows me Active heartbeat at node1 only.
I am using vmware 7 workstation, my vmx file is as fallows. I am great-full for you help.
