Autonomous Database Blog series

Oracle has just released the Oracle Autonomous Transaction Processing Cloud Service. This is the second service of the Oracle Autonomous Database Cloud Services, after Oracle Autonomous Data Warehouse Cloud Service which launched earlier this year. I have been asked to produce some collateral for the new offerings which will surface here as well as on other sites. I hope they will be interesting for you and give you some insights into the technologies, how they work, and how you can get the most out of them.

To follow along with the code samples that you will see, I have created a new GitHub repo:
If you are on GitHub, feel free to give it a star and fork away. In the case that you are not, you will still be able to browse and download all code samples.

All blog posts will be marked with the tag Oracle Autonomous Database to make it easier for you to filter them.

Setting up Docker on Oracle Linux 7

Docker has become widely popular in the last couple of years. I use it on a regular basis these days for running Oracle databases on my laptop. Docker is available on all popular Linux distributions, as well as Mac and Windows, and of course Oracle Linux is no exception. Since a long time Docker ships with the Oracle Linux 7 addons yum repository. Having setup Docker on Oracle Linux numerous times, I thought it would be good for me to document my steps for others to follow.


  1. Update Oracle Linux and UEK to the latest version (OL 7 and UEK5): yum upgrade
  2. Enable the addons yum repo: yum-config-manager --enable *addons
  3. Install docker-engine: yum install docker-engine

Upgrading UEK kernel on Oracle Linux 7

linux_penguin_with_logoIn general I work almost exclusively on Macs these days. However, for work and various other reasons I always tend to have a VM with Linux on my Mac to test, run, script things. My VM runs Oracle Linux (OL) on VirtualBox. Oracle Linux just makes a lot of sense for me as we run everything on Oracle Linux internally and in general it is a solid Linux distribution. Of course, once in a while I have to update my Linux version as well to make sure that my Linux environment remains on the latest and greatest. Right now is such a time again as Oracle Linux 7 Unbreakable Enterprise Kernel 5 just released. In the past I was always a bit scared about upgrading kernels because I had little clue of what I was doing. 🙂 Turns out that it is a lot easier than one might think, and here is how you do it:


  1. Download new repo list: wget
  2. Enable the new repo: yum-config-manager --enable ol7_UEKR5
  3. Upgrade the environment: yum upgrade
  4. Reboot the environment: reboot

Creating an Oracle Database Vagrant box

Oracle recently launched a new GitHub repository for providing people with Oracle software inside Vagrant boxes. If you have ever setup an Oracle database inside a VirtualBox VM, whether it is as your sandbox environment, to explore Oracle database, or to use it as a full-on development environment, things have just gotten a lot easier for you. With Vagrant, you can now provision an Oracle database inside VirtualBox in a matter of a couple of simple steps.

Creating an Oracle REST Data Services Docker image

Oracle has added Oracle REST Data Services (ORDS) to the Docker build files family on GitHub, which means that you can now easily dockerize ORDS. If you don’t know yet what ORDS is, it’s a free technology from Oracle that allows you to REST-enable your Oracle databases. More specifically, with ORDS you can just fire off regular REST calls to modify or retrieve data from one or many Oracle databases without having to know how to write SQL; not that knowing SQL is a bad thing! 🙂 In modern application and microservices architectures REST has become more and more popular for exchanging information. ORDS enables you to easily exchange data from and to Oracle databases via REST without having to write lines and lines of code yourself.  For more information on what ORDS is and what it can do, check out Jeff Smith’s blog post about ORDS.
