After last week's release of Red Hat's RHEL (Red Hat Enterprise Linux) 7.3 operating system, now Oracle is proud to announce the general availability of its Oracle Linux 7.3 distribution for 64-bit (x86_64) servers.
Based on the Red Hat Enterprise Linux 7.3 and powered by its kernel-3.10.0-514.el7 Linux kernel package, Oracle Linux 7 Update 3 appears to be the first release of the server-oriented Linux-based operating system to use Oracle's new Unbreakable Enterprise Kernel Release 4 (UEK R4), versioned kernel-uek-4.1.12-61.1.18.el7uek. Oracle Linux 7.3 also introduces UEFI and Secure Boot support.
If you just want to download the graphical version of Oracle enterprise Linux then simply deselect all the ISO files and select the only one Oracle Linux Release 7 update 6 for x86 (64bit), 4.3 GB ISO file. In the same way, in future when new updates will available you can follow the same procedure to download them. Oracle Linux Release 7 Boot iso image for x86_64 (64 bit). The.iso installation file you can download is a disk image. It's a data block copy of the physical storage media. The installation disk image already contains a fllesystem and bootloader. All you might have to do is to duplicate the raw data of the.iso image to your raw USB media. Oracle Linux is often used to host a Oracle database Guide to Installing Oracle 11G on Oracle Linux 7.4. The software required to follow this process will be VMWare Workstation Pro 14 (Free Trial Available). Oracle Linux Release 7 is released through Oracle Software Delivery Cloud on DVD ISO image. The set contains installable DVD and 2 source code DVDs. Most of the systems can be booted with the installation DVD. Installation To install Oracle Linux 7 from DVD media, follow the following steps: 1. Download the compressed binary DVD images. Oracle Enterprise Linux is a freely distributed operating system based and compatible with the Red Hat Enterprise Linux distribution. It is an enterprise-ready server Linux OS designed to be used on small and medium-sized businesses.
'This is the first Oracle Linux 7 ISO to include UEK Release 4 (UEK R4). Please note that new installations of Oracle Linux 7 Update 3 will install and boot the UEK R4 kernel by default. However, updates to existing Oracle Linux 7 environments require the user to explicitly install UEK R4 and will not automatically replace existing UEK R3 kernels,' wrote Teri Whitaker, Program Manager at Oracle, in the release announcement.
Oracle Linux 7.3 supports the latest UEK R3u7 and later
In the good tradition of the operating system, Oracle Linux 7.3 supports both the Unbreakable Enterprise Kernel (UEK) and Red Hat Compatible Kernel (RHCK) kernels, but it boots the former by default, while the latter can be manually enabled by administrators. However, Oracle Linux 7 Update 3 continues to support the latest Unbreakable Enterprise Kernel Release 3 Update 7 and later.
As expected, those who have an active support subscription for Oracle Linux can now download the ISO installation images of Oracle Linux 7.3 from My Oracle Support, as well as from Oracle Software Delivery Cloud. Oracle also provides individual RPM packages for Oracle Linux 7.3 on the Unbreakable Linux Network (ULN) and a public YUM server. Users are encouraged to update their installations as soon as possible.

Oracle Database is an object-relational database management system (RDBMS) developed by Oracle Corporation. The Oracle Database is available under a Proprietary and OTN Standard License. The supported operating systems are Redhat Enterprise Linux (x86-64), SUSE and Oracle Linux, Microsoft Windows x86-64 and IBM Linux.
In this tutorial, I will show you step-by-step how to install Oracle 12c on a CentOS 7 x86-64 machine. This includes the preparation and configuration of the CentOS 7 machine for the Oracle 12c installation, the Oracle 12c installation and testing the database with the Oracle Database command line utility 'sqlplus' and the web-based Oracle Enterprise Manager.
Prerequisites
- CentOS 7 64-bit.
- At least 1 GB RAM Memory.
- Root Privileges.
Step 1 - Install required Packages
As the first step, we have to install a lot of packages required by Oracle database, like GCC, Binutils, Glibc etc. We will install them from the Centos repository with the yum command.
Install packages required by Oracle database with yum.
Step 2 - Configure User and System
Oracle Database will run under a normal Linux user and not with root privileges. In this step, we will create a new user and group for Oracle.
Create new groups named 'oinstall' and 'dba', then create a new user 'oracle' and add it to the 'oinstall' group.
New user and group are created, now we need to configure our system for the Oracle installation. There are some kernel parameters that we must configure for the Oracle installation.
Edit 'sysctl.conf' file with vim.
Paste configuration below.
Save the file and exit the editor.
Now run the commands below to display all kernel parameter and apply the new values.
Next, we need to configure some limits for the oracle user. Specify the max number process and max number of open files descriptors.
Edit 'limits.conf' file with vim.
Paste the configuration below.
Save the file and exit vim.
New user and system configuration is finished.
Step 3 - Configure Desktop
The Oracle installation requires GUI access, so the fastest way for this is by installing a X Window System on the server, and then access the GUI app with ssh -X option.
Install X Window System with yum command below.
When the installation is done, open a new terminal and connect to the server as oracle user with the ssh command option below. Try to run the GUI application and you will get the application screen.
Step 4 - Download Oracle Database
If you do not have an Oracle account yet, register one and then log in to download 12c for Linux.
Below are my oracle files.
Install zip and unzip to extract the archives.
Oracle Linux 6.7 Iso Download
Extract the Oracle files to a new directory named 'stage'.
Change owner and group of the '/stage/' directory to the oracle user and oinstall group.
Next, create new directories for the Oracle installation files and Oracle database files.
Directory 'u01' is for the Oracle installation files and 'u02' for the Oracle database files.
Change owner and group of the new directories and set permissions to '755'.
Oracle is downloaded and the new directories for the installation are ready.
Step 5 - Install Oracle Database 12c
Open a new terminal and connect to the CentOS 7 server with the ssh command below.
Go to the stage database directory and run the installer file.
The script will check the server, make sure all tests are passed.
And you will see the GUI installation screen below, there click 'Next'.
At 'Installation Options', choose 'Create and configure a database' and click 'Next'.
Under the 'System Class' section, choose 'Desktop Class' and click 'Next' again.
'Typical Installation' info.
- Oracle base: '/u01/app/oracle'
- Software location: /u01/app/oracle/product/12.1.0/dbhome_1
- Database file location: /u02
- Database edition: Default
- Character set: Default
- OSDBA group: dba
- Global database name: Type your own name
- Administrative password: Type your own password
- Confirm password: Type again
- Uncheck the 'Create as Container database'
Click Next.
At 'Create Inventory', enter the path below:
Inventory Directory: /u01/app/oraInventory
oraInventory Group Name: use 'oinstall' group.
Click 'Next'.
Make sure all checks completed without an error, then you will see a summary of the Oracle configuration.
Click 'Install'.
Installation process.
During installation process, you will be asked to execute some scripts as root.
Open a new terminal and execute the files.
You will get the results below.
Next, you will be shown a new pop-up from the database configuration assistant, please wait, it takes a time.
When the 'Database Configuration Assistant' is finished, you will see the info below:
Click 'Ok' and the Oracle database installation is done.
Click 'Close'.
Step 6 - Testing
The Oracle installation is finished and ready for testing. I will try to access Oracle from the command line first.
Log in to the server and access the oracle user.
Login to the oracle user.
Execute the commands below to set the oracle environment.
Access the oracle database utility 'sqlplus', log in as 'sysdba' privileges.
Oracle comes with some default users. Run the query below if you want to change the default user named 'sys'.
Sqlplus is working fine.

Login with user 'system', and the password you have setup as 'Administrative Password' in step 5. Or you can use the 'sys' user and your password.
After login, you will see the 'Oracle Enterprise Manager' dashboard below.
The Oracle Database 12c installation and configuration is done.
