Installation of Oracle Enterprise Linux on VMWare
Recently, Oracle announced and released it’s Enterprise linux. Time to check out what’s it all about!
While downloading the software from OTN, I was surprised to see there were no less than 8 discs, I downloaded all of them (a hefty 4.5 gigabytes) and found out after unzipping that the first 4 discs are installation discs and the other four contain only sources. The other four disks contain additional packages and software. So save yourself the bandwidth and cd-roms and start with the first four.
I do not have a spare machine for installing Linux so I installed VMWare Workstation and hooked up a 250 GB external harddisk. Let’s roll!
I use VMWare Workstation 5.0. I choose a pre-configured image which is named “Red Hat Enterprise Linux 4”. I was told OEL and Red Hay linux are very similar, so that should work fine. The imagesize is 15 gigabytes, and initially my virtual machine has 256 MB of memory assigned.
As you can see, the interface is modern and very user-friendly.
I save myself the trouble of pondering what partition should be which size, so I let the setup decide.
OEL does find my virtual disk and I choose to install the partitions in the free space available.
It creates a 512MB swapdrive and the remaining space is one logical volume group. The partition type is ext3. It’s fortunate to see that the size of the swapfile meets the minimum requirements for installation of Oracle Application server (which is also 512MB).
In the Package group selection step you can choose which tools and utilities you wish to install. Note the Server Configuration package which still mentions Red Hat instead of Oracle!
After all steps are followed, the actual installation begins.
Some post-installation tasks; confirm the license agreement, set date and time and create a system user.
And… Thunderbirds are Go! Now everything is working, it’s time to install your own software.
As you see, installing Linux goes without any pain. All the hardware works without tweaking, as well as the KDE graphical user interface. Really, I took me a lot more time to write this blog than to do the actual install. My guess of the total installation time: about half an hour.
Next action for me: installing Oracle 10g for Linux. But I’ll save that for the next blog!
Vmware and oracle linux
What is Oracle Linux?
Oracle Linux is an open source operating system available under the GNU General Public License (GPL) and is available for free download.
Oracle Linux includes two kernels:
Unbreakable Enterprise Kernel, tracks mainline Linux kernel closely, and offers the latest features and
tested performance and stability
In this tutorial we are going to install Oracle Linux 5 Update 8 (64 bit) prepared to install Orcale Database 11g on it.
What we are going to cover:
1. New virtual image creation
2. Linux Installation using Linux ISO Image download from Oracle eDelivery website
We will include into installation Oracle Validated package (rpm included in distribution) which is automatically configuring system components like Linux kernel parameters, creates oracle users and groups, installs rpm packages required by Oracle products and Oracle Universal Installer. It makes OS ready for installation of most Oracle products, like Oracle Database or WebLogic Server, without additional manual configuration steps – very handy.
1. Once we have downloaded and installed VMware Player or Workstation from www.vmware.com website we are ready to launch the application and press Create a New Virtual Machine button.
In the end press Edit Virtual Machine Settings and configure all image parameters.
Don’t forget to mount Downloaded Linux ISO image as CD/DVD device.
Note: 1GB Memory , 1 CPU and 20 GB hard disk would also be enough.
2. Power up virtual machine and Linux Installer will boot up.
As we mentioned above we are going to include oracle-validated package from System Tools packages group.
As you can see at the last screenshot, the oracle user has been created and has been assigned to oinstall and dba groups (one of the several actions performed by oracle-validated package).
UPDATE: There is one package which oracle-validated doesn’t install – unixODBC-2.2.11-10.el5.i386.rpm
That package is required by the Oracle Universal Installer when installing Oracle Database 11g R2 on Oracle Linux 64 bit.
Let’s install missing package.
You have still Linux ISO image mounted in vmware machine.
As “root” user run the following commands:
[[email protected] ~]# mount /dev/cdrom /media mount: block device /dev/cdrom is write-protected, mounting read-only [[email protected] ~]# rpm -Uvh /media/Server/unixODBC-2.2.11-10.el5.i386.rpm warning: /media/Server/unixODBC-2.2.11-10.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159 Preparing. ########################################### [100%] 1:unixODBC ########################################### [100%]
That’s it. System is ready for an Oracle Database installation.

Oracle Linux (OL, formerly known as Oracle Enterprise Linux) is a Linux distribution packaged and freely distributed by Oracle, available partially under the GNU General Public License since late 2006. It is compiled from Red Hat Enterprise Linux (RHEL) source code, replacing Red Hat branding with Oracle’s. It is also used by Oracle Cloud and Oracle Engineered Systems such as Oracle Exadata and others.
Potential users can freely download Oracle Linux through Oracle’s E-delivery service (Oracle Software Delivery Cloud) or from a variety of mirror sites, and can deploy and distribute it without cost. The company’s Oracle Linux Support program aims to provide commercial technical support, covering Oracle Linux and existing RHEL or CentOS installations but without any certification from the former (i.e. without re-installation or re-boot). As of 2016 Oracle Linux had over 15,000 customers subscribed to the support program.
Oracle Linux, like CentOS and Scientific Linux, is a binary clone of the Red Hat Enterprise Linux (RHEL) distribution. In this relationship Red Hat is known as the upstream vendor. What does this mean? These groups download the RHEL source code, remove trademarks, compile it, create a distribution and allow you to downloads and use it for free. This is perfectly legal because the software that makes up this Linux distribution is covered by an assortment of open source software licences, including GPL. Indeed, without the these open source software licenses RHEL would not exist as it is the reason Red Hat can legally create their distribution, since they are not the originators of all of this code.
VMware Workstation is a virtual machine software that is used for x86 and x86-64 computers to run multiple operating systems over a single physical host computer. Each virtual machine can run a single instance of any operating system (Microsoft, Linux, etc.) simultaneously. VMware Workstation strongly supports hardware compatibility and works as a bridge between the host and virtual machine for all kinds of hardware resources including hard disks, USB devices and CD-ROMs. All device drivers are installed via the host machine.
VMware was established in 1998 and has produced many products for virtualization. VMware Workstation was launched by VMware in 2001.
VMware Workstation allows for the installation of multiple instances of different operating systems, including client and server operating systems. It helps the network or system administrators to check, test and verify the client server environment. Administrator can also switch between different virtual machines at same time.
VMware Workstation has its limitations, including hardware support, operating system issues, and network protocols hurdles.
VMware Workstation is the wildly popular software which facilitates creating and operating virtual machines or VM’s right on your x86 based laptop or desktop computer.
Oracle Linux is pretty much the same as any other installation. Download the ISO, burn the ISO onto a USB drive, boot from the USB drive, and click the Install icon.
