I specialize in working with Docker and Oracle Database (version 7 onwards), leveraging official Oracle images to build custom containers based on Oracle Linux, as well as performing general database server installations.

Beyond containerization, I handle bare-metal and server-specific installations for databases and application servers. My core expertise lies in deploying cluster environments and high-availability databases. Additionally, I prepare specialized images to serve as automated installers across servers, enabling rapid provisioning for both Docker environments and Oracle VM infrastructures.

Using Oracle Linux via SupportedImages has had a positive impact on our organization, particularly in supporting certified Oracle Database environments. Oracle Linux and its associated application servers—such as Enterprise Manager—provide crucial alignment for bug fixes and technical support.

While alternative distributions like Red Hat sometimes receive priority support for third-party storage drivers and compatibility updates, adopting Oracle Linux ensures a unified support channel. Using non-Oracle images often resulted in finger-pointing between vendors during troubleshooting, leaving us stuck between parties. Oracle Linux eliminates this friction, streamlining problem resolution and ensuring end-to-end accountability."

The best features that Oracle Linux 7 | Support by SupportedImages offers include support for the database, which is the main reason we use Oracle Linux, and also because it is free. The repositories are very good, although not as extensive as those of other vendors, but they generally meet our needs. The images usually come updated and do not have errors during installation.

I consider it relevant to mention virtualization, and also automation already included in the free packages, and the integration with the Oracle Install package, which is an Oracle installer that greatly simplifies the installation of the Oracle product itself, the database. This helps a lot at installation time and speeds up the process.

The overall installation experience could be enhanced by expanding the options available during initial setup, particularly regarding software repositories, application packages, and virtualization models. Currently, the installer feels limited by primarily supporting Oracle Virtual Machine (OVM), rather than offering native integration for modern container runtimes like Docker or alternative virtualization options.

While Oracle Linux is a solid, reliable product, documentation around customization could be improved. The current guides provide basic examples, but they lack deep, diverse coverage on building custom container images or automating deployments. Expanding manuals for advanced image creation and enterprise automation would be a huge value-add.

Installer Customization & Unattended Deployments: I rate the product an 8/10. Although the modern installer interface is intuitive, it needs granular customization options at setup time. Users should be able to define server roles, package selection, network settings, and user configurations directly from a unified console. Additionally, adding the ability to export and save those setup preferences (e.g., Kickstart files/profiles) would significantly streamline silent, offline installations across scaled infrastructure.

I have been working with Oracle Linux in general since Oracle started creating its own images, so I imagine that must be more than 10 years.

I find the images to be reliable, and I am able to get good results with the images they currently provide. Oracle Linux 7 | Support by SupportedImages is stable, and I have not had any problems with it.

I normally use the images to create clusters, and I have not had any problems.

Regarding database support, normally I do not need to contact Oracle. I have had some issues where I had to contact Oracle support, but it was related to other types of products, not the database, not the operating system itself, but compatibility, for example, with Oracle ASM and Oracle Database versions. At installation time, I did have problems and had to contact Oracle for support with the installations.

Customer support is very poor and not very good. I would rate it from poor to fair. I would rate customer support a five on a scale from 1 to 10.

Before Oracle Linux 7 | Support by SupportedImages, I used SUSE Linux and also Red Hat, but we switched from SUSE Linux because the vendor started certifying Oracle Linux first and also started making Oracle products install almost transparently on Oracle Linux, not showing the same ease for other products or providing the same facilitators for the other products in this case, SUSE Linux and Red Hat.

Setup: Moderate (Straightforward interface, but complex for deep customization)

"The initial setup is generally straightforward, thanks to an intuitive installer interface. However, configuring advanced options can become complex due to limited customization out of the box.

• What was easy: The base installation is user-friendly and quick to get up and running for standard deployments.
• Where it gets complex: Setting up specific network configurations, package repositories, and non-standard virtualization models (like custom Docker environments) requires extra manual tweaking and custom scripting.

We purchased our licensing through Oracle, but all design, configuration, and automated deployment work was completed internally by our own engineering team. Our experience with the reseller was limited strictly to software procurement, which was smooth.

Automation delivers a immediate and high return on investment (ROI). Spending just one or two days developing an automated deployment script enables us to rapidly provision 200 to 400 servers in a fraction of the time. Because our base images are pre-configured and reliable, every deployment yields fully certified environments for Oracle software, driving significant cost savings and accelerating operational efficiency.

I do not work with the licensing side, and the configuration cost is fine.

Before choosing Oracle Linux 7 | Support by SupportedImages, I was already using other solutions, but the company chose to use Oracle Linux due to licensing reasons and support from a single vendor.

On a scale from 1 to 10, I would rate Oracle Linux 7 | Support by SupportedImages an eight.
