Exadata Simulation on VMWare Part-1
Hi Guys,
After long time blogging new post, this time we will see how to simulate Exadata environment in vmware.
Note :
This is for learning purpose and a simulation to practice the commands but the actual performance and other features can only be experienced on real exadata machines.
My environment going to be:
Storage cell servers:
- Exacel01.hussain.net = 192.168.0.130 (Public)
10.0.0.100 (Private)
2. Exacel02.hussain.net = 192.168.0.131 (Public) 10.0.0.101(Private)
Database Compute nodes:
- Exadb01.hussain.net = 192.168.0.133 (Public) 10.0.0.50 (Private)
2. Exadb02.hussain.net = 192.168.0.134 (Public) 10.0.0.51 (Private)
Virtual ip’s:
192.168.0.152 = exadb01-vip.hussain.net
192.168.0.153= exadb02-vip.hussain.net
Scan ip’s:
Exa-scan.hussain.net = 192.168.0.163
192.168.0.164
192.168.0.165
Operating system: Oracle Enterprise Linux 5.8
Exadata storage software version: 11.2.3.2.1 and zip file is V36290-01.zip (Download from oracle edelivery)
Grid and Database version : 11.2.0.3
Now, will create a VM and will clone the same for the rest of three servers.
Please follow below screenshots and install OS OEL 5.8
After rebooting system, login into the system using root credentials.
And setup network ipaddress, install VMware tools.
In my case: Ip address 192.168.0.130 (Public) and 10.0.0.100 (Private)
Configure yum repository, actually it’s not needed for cell server, but I’m cloning the same server for database nodes right where I require yum repository to install database related rpm.
Update the /etc/hosts file with below information.
Update the below configuration files with specified parameter values.
vi /etc/sysctl.conf
fs.file-max = 655360
=============================================
vi /etc/security/limits.conf
* soft nofile 655360
* hard nofile 655360
==============================================
vi /etc/grub.conf
default=1
==============================================
vi /etc/bashrc
export DISPLAY=:0
===============================================
Vi ~/.rpmmacros
%_query_all_fmt %%{name}-%%{version}-%%{release}
================================================
mkdir /var/log/oracle
chmod 775 /var/log/oracle
================================================
Copy the Exadata storage software to /stage directory and extract it.
Now install JDK and cell software rpm which we extracted and restart the server.
Create the soft links for the extra added disks to use as celldisk.
fdisk -l 2>/dev/null |grep ‘B,’
mkdir -p /opt/oracle/cell11.2.3.2.1_LINUX.X64_130109/disks/raw
cd /opt/oracle/cell11.2.3.2.1_LINUX.X64_130109/disks/raw
ln -s /dev/sdb exacel01_DISK01
ln -s /dev/sdc exacel01_DISK02
ln -s /dev/sdd exacel01_DISK03
ln -s /dev/sde exacel01_DISK04
ln -s /dev/sdf exacel01_FLASH01
ln -s /dev/sdg exacel01_FLASH02
Check the services and we should have to configure cell(in my case) with eth1 ipaddress i.e 10.0.0.100.
Check the physical disk and Lun
By using celldisk create the griddisk and repeat the whole activity for exacel02 server as well, as we are going to have two Exadata storage servers.
And these grid disks are used to configure the diskgroups through ASM from database compute nodes.
In next post, will see how to install and configure Oracle Grid Infrastructure and RDBMS software.
Happy Learning,

Hello ,
Please publish your second part of this post

Hi, Hari shankar,
Sorry for late reply, will do that soon.

waiting for your part 2 man. Thanks!
Hi Sir — I have successfully installed cell RPM but , post that i am struggling to fix GUI issue . for more that i have recreated different OS version 5.3 / 5.8 /5.10 but issue remain same .
tried to set en variable / try to run from VNC by configuring it . I am still not able to understand/fix issue which you fixed and worked for you easily ………. please help me in this ….i m totally frustrated because of this …or suggest alternate option

Hi,
Do you still have a installation guide how to build your own Exadata VMware ?
Can’t find the download *.zip files anymore and can install it like your discripted.
Do you have a up-to-date (2020-09-26) installation guide ?
I am new to Exadata Oracle installation but want to learn about this.
Kind Regards,
Chris
