Why Oracle on Linux?

Oracle Database Tips by Donald BurlesonDecember 14, 2015

Why Oracle on Linux?

Linux that is running Oracle offers the following advantages:

n  Lower costs via GPL licenses and suppresses additional license costs for the OS

n  Stable OS and a huge community for support

n  Higher availability, flexible and scalable

n  Excellent support from Oracle on Linux

Therefore, Linux and Oracle is an outstanding choice to support the IT systems.


Linux has a long history at Oracle Corporation. The first commercial version started in 1998 and developed so well that Oracle provided a code level support on Linux and had an 80% share of the market. All key Oracle products are run under Linux. Oracle itself runs all the following business applications only on Linux:, Oracle financial system, Oracle demo system and Oracle On Demand.


Oracle RDBMS systems require from an operating system the following characteristics:

n  Asynchronous I/O management that enables I/O to be handled without waits as the processing continues, thus avoiding I/O bottlenecks. With synchronous I/O, the requests are submitted to the OS and the writing processes are blocked while they wait until the write is confirmed as completed.

n  Memory support, more than 4 GB to be allocated

n  Ability to run on servers with multiple processors so tasks can be dedicated to two or more processors

n  Support cluster technology

n  Large support of hardware platforms and components such as network cards, disk controllers and such

n  Robust I/O support; for example, RAID, SAN or NAS controllers

All those needs are covered by Linux, and especially in the newest kernel, the support of multiprocessing is further enhanced.

Potential Users of Linux and Oracle

Linux started in the internet arena as a platform for web servers and other internet applications running the web server Apache. Linux is now on its way to replacing all UNIX servers and it is a strong competitor of Microsoft Windows.


The following organizations and people are using Linux for their IT systems:

n  Small enterprises and personal users who are willing to have cheap IT systems and standard solutions to support their small businesses. They need accounting, email, spreadsheets and word processors. All those applications exist under Linux and furthermore, Oracle can be used as repository storage for the information.

n  Medium enterprises that are looking for simple and efficient IT systems to support the business and are willing to buy designed software. The IT people in those corporations have a general knowledge of IT systems.

n  Corporations and service providers, like power suppliers and hospitals, are big users of IT systems; they have critical systems that need to be up seven days a week and 24 hours a day. With solutions based on Oracle and Linux, they will be able to get those IT systems up to that level.

n  Universities, education and research institutions that need a platform for administrative work but also need a platform for scientific computing or research. Obviously, the benefit of a free-of-charge OS and a database that is stable and efficient is a must-have solution.
