So you want to play with Oracle 11gs RAC?

Heres how.Installing Oracle 11g RAC on virtual servers using VMware.

This post describes the installation of Oracle 11g RAC on virtual servers.Hardware

The following hardware was used for the installation:Operating

system

Processor Memory HDDs

Windows XP

SP2 (32 bit)

Intel P4 3Ghz 3Gb 1 x 160Gb 7200rpm & 1x

250Gb 7200rpm. Both on

Ultra ATA Controllers

Youll need at least 3Gb of RAM for this installation as the virtual machines will be configured with 1Gb of

RAM each, leaving 1Gb for the host operating system. The virtual machines further requires a total of 40Gb

of storage.

Software

Oracle 11g (11.1.0.6) Database & Clusterware Software

Oracle Enterprise Linux 4 (Update 5)

VMware Server 1.0.3

General

For obvious reason this installation should never be used for Production or Development purposes. This type

of environment is however extremely helpful if you want to learn and understand Oracle RAC and you do not

have access to traditional hardware resources.

I used VMware Server (1.0.3) to facilitate my virtual machines. If you have not done so already download the

software here. Youll need to register to get an activation code, but it is a free product.

Configure your first virtual machine:

1. Install VMware Server and launch.

2. Select local host and OK to close the pop-up window.3. Select New Virtual Machine from the VMware Server Console to create the hardware specification for

your first virtual machine.

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-391, default 391):

Using default value 391

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.


61/197

The key sequence after entering the fdisk command is:

n [return] p [return] 1 [return] [return] [return] w [return]

39.Prepare raw disksBind the OCR and Voting Disk partitions to raw devices. To do this edit the file:/etc/sysconfig/rawdevices and add the following lines:/dev/raw/raw1 /dev/sde1

/dev/raw/raw2 /dev/sdf1

Restart the raw devices service for the new settings to take effect:

[root@rac1 ~]# service rawdevices restart

Assigning devices:

/dev/raw/raw1 > /dev/sde1/dev/raw/raw1: bound to major 8, minor 65

/dev/raw/raw2 > /dev/sdf1

/dev/raw/raw2: bound to major 8, minor 81When you restart an Oracle Enterprise Linux 4

system, ownership and permissions for raw devices will revert to the root owner. To prevent this from

happening edit the raw devices section of the /etc/udev/permissions.d/50-udev.permissions file to look


62/197

like the following:

40.Create users and groupsIn Oracle 11g Oracle recommends a new system group (osasm) if you want to separate the ASM

administration function from your DBAs. Likewise they recommend creating a separate group (crs) for

Clusterware administration. I will however create a single software owner (oracle) for all Oracle

software.To create the necessary groups and users execute the following from the command line as the

root user:# groupadd -g 501 oinstall

# groupadd -g 502 dba# useradd -g oinstall -G dba -s /bin/ksh oracle

# passwd oracle

41.Configuring kernel parameters and shell limitsAppend the following to the /etc/sysctl.conf file as the root user:kernel.sem = 250 32000 100 128

kernel.shmmax = 536870912

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 4194304net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 262144

You can issue the following command for these settings to take immediate effect: /sbin/sysctl p


63/197

42.Add the following entries to the /etc/hosts file as the root user:Public 192.168.1.50 rac1.startoracle.com rac1

192.168.1.60 rac2.startoracle.com rac2

VIP 192.168.1.51 rac1-vip.startoracle.com rac1-vip

192.168.1.61 rac2-vip.startoracle.com rac2-vip

Inter-connect 10.10.10.50 rac1-priv.startoracle.com rac1-priv

10.10.10.60 rac2-priv.startoracle.com rac2-priv

43.The /etc/hosts file should now contain the following entries:

Restart the network services to pick up the new settings with the following command: # service network

restart

44.As root create the following oracle directories and change the ownership to oracle:# mkdir -p /u01/app/oracle/product/11.1.0/crs


64/197

# mkdir /u01/app/oracle/product/11.1.0/db_1

# mkdir /u01/Stage11g

# chown -R oracle:oinstall /u01/app

# chown oracle:oinstall /u01/Stage11g45. Set shell limits for the Oracle user

As the root user add the following lines to the /etc/security/limits.conf file:oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536Add the following as the second last lines in the /etc/pam.d/login file if

it does not exist:

session required pam_limits.soAppend the following to the /etc/profile file:if [ $USER = oracle ]; then

if [ $SHELL = /bin/ksh ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fiumask 022

fi

46.Install the ASMLib packageDownload the ASM Lib package from the Oracle Technology Network. Download the package named
http://www.oracle.com/technology/software/tech/linux/asmlib/rhel4.htmlhttp://www.oracle.com/technology/software/tech/linux/asmlib/rhel4.html


65/197

oracleasmlib-2.0.2-1.i386.rpm under the section Intel IA32 (x86) Architecture and install it as theroot user with the following command: # rpm -i oracleasmlib-2.0.2-1.i386.rpm

47. Clone the virtual machineAt this point shutdown the virtual machine and copy all the files from the virtual machines directory tothe directory for the second virtual machine. Once this is complete add the second virtual machine as

follows:

Select the Home tab in the VMware Server Console.

Select Open Existing Virtual Machine and browse to the cloned virtual machine directory and select the

file Red Hat Enterprise Linux 4.vmx. The cloned virtual machine will now show up in the VMware

Server Console.

Rename the new virtual machine:

To rename the virtual machine select Edit virtual machine settings and select the Options tab. Change

the virtual machine name (EL4_11gRAC2) and click OK to continue.


66/197

Start the new virtual machine (while leaving the old one powered off) and log in as root. Whenprompted if you want to create a new UUID for the virtual machine select Create and OK to continue.

Upon startup you will be asked to remove the 2 old network cards and add new network cards.

Select Remove Configuration to remove the network cards. Youll need to do this twice.


67/197

Select Configure to configure the first network card.

Enter the IP configuration for the second virtual machines first network card (Private) as per the table

in step 36. OK to continue.


68/197

For each network device do the following:


69/197

Select the device and Select Edit.

Make sure the IP address is correct for each device eth0 (the bridged network connection) should be

on the public network and eth1 (the host-only network connection) should be on the private network. If

the settings are incorrect update the IP address, subnet mask and default gateway.


70/197

Select the Hardware Device tab and click Probe to get the new MAC address for the device. Select OK

to continue.


71/197

Select the DNS tab and update the Hostname to rac2.startoracle.com. From the file menu select Save

72/197

Restart the virtual machine for the changes to take effect and start the first virtual machine. Both virtual

machines should now be up and running.Note: To test the network setup, ping the nodes from each

other using the public and private ip addresses (the virtual ip address is not pingable at this stage).

48.Enabling SSH User EquivalencyThe OUI (Oracle Universal Installer) uses the ssh and scp commands during installation to run remotecommands and copy files to other nodes in the cluster, therefore you need to setup user equivalency for

the Oracle user on all nodes.Perform the following in order to setup user equivalency:As the oracle user

on node rac1:$ mkdir ~/.ssh

$ chmod 700 ~/.ssh


73/197

$ /usr/bin/ssh-keygen -t rsa

Note: Whenever prompted for a passphrase leave it empty and press return.

As the oracle user on node rac2:

$ mkdir ~/.ssh$ chmod 700 ~/.ssh

$ /usr/bin/ssh-keygen -t rsa

As the oracle user on node rac1:$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

$ ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

$ scp ~/.ssh/authorized_keys rac2:/home/oracle/.ssh/

Perform the following as the oracle user on node rac1 and then node rac2:ssh rac1 date

ssh rac2 date

ssh rac1.startoracle.com date

ssh rac2.startoracle.com date

ssh rac1-priv date

ssh rac2-priv date

ssh rac1-priv.startoracle.com date

ssh rac2-priv.startoracle.com date

Hi T

The 10g installation is exactly the same, except you need to configure the hangcheck timer on Linux as an

additional task. In 11g the Process Monitor Daemon (oprocd) monitors the system state of cluster nodes so

you no longer need the hangcheck timer.

Kind Regards

Hi,Great article..

I always install seperate homes for the asm and db because if you upgrade in the future

15. MiladinJanuary 22, 2008 at 6:23 pm

Good work.For someone who is not familiar with this install picutres are very usefull.

Only thing is missing here is to install ASM in a separate Oracle home.It is for High Availability and

maintenace.

Thats mean after installing Oracle Database Software do one more install

ORACLE_HOME=:/u01/app/oracle/products/11.1.0/asm directory.

Choose option Configure ASM.

Thanks.

Hi Miladin & Pekka Koppanen

Thanks for your valuable feedback. You are indeed right. Seperating the ASM and Oracle Homes in a

production environment is recommended. I wanted to save disk space hence the reason for using only one

home!

First of all thank you for creating these instructions. They are very helpful.

I have managed to create the two VM-s and they are able to communicate among themselves. But I am not

able to see the outside world (internet) from within the VM-s. Can you tell me what I might be missing? I

tried both the bridged and NAT. The former does not allow the host computer to connect to the VM but thelatter does. But with the NAT, I cannot connect to the host or the internet from within the VM-s.

Thanks.

Hi Dallas

You dont need OCFS/OCFS2. I used the following:

1.) Raw devices for the voting disk & OCR

2.) Local file systems for the Oracle & Clusterware Homes

3.) ASM for the database files.

You can place the following on OCFS: Oracle software, Oracle database files, Voting disks, OCR & spfiles if

you want to.

Cheers

Frikkie


Hi Jarek

This is done under the section Install Oracle Enterprise Linux.

Great how-to guide. Nice to update for RHEL5U2 which does not support the raw device any more. The

information here about raw devices needs to be updated.

I followed the instructions on the following website, which seems working:

nowhere else. Have I missed a step?

Great!!! I have one doubt regarding ASM and RDBMS, Oracle 11g recommends seperate HOME for ASM and

Hi Ravi

This is perfectly fine, although it does complicate matters when it comes to upgrades & patching. Itstherefore recommended to have separate homes for ASM and the database in production environments.

Frederik,

This is a really nice article for Installing RAC.

However I got stuck at one point and cannot move any forward.

I followed the instructions above for installing linux and I find the unixODBC rpm missing. I could not find it

in the CDs either. I donwloaded it from the internet but its complaining about lot of other pre-requisites.

Please let me know if you had to do anything else to get those packages. For this reason, I am not able to gopast the runClufy stage. Thanks.
