Oracle Linux vs. Red Hat Enterprise Linux: Clearing the Confusion

 


For many years, people have often assumed Oracle Linux and Red Hat Enterprise Linux (RHEL) are the same—or weren’t sure what truly sets them apart. While both share the same open-source upstream code base, Oracle Linux offers more flexibility, cost efficiency, and performance tuning.

🔍 Key Highlights

  • Binary Compatibility: Oracle Linux is 100% compatible with RHEL, ensuring that any application running on RHEL will run flawlessly on Oracle Linux.

  • Two Kernel Options:

    • Red Hat Compatible Kernel (RHCK) – identical to RHEL’s kernel.

    • Unbreakable Enterprise Kernel (UEK) – optimized for Oracle workloads and cloud performance.

  • Lower Total Cost: Oracle Linux delivers enterprise-grade support at a lower price, without additional subscription fees for updates or security patches.

  • Free Access to Updates: Oracle provides open and free access to all updates and patches through the Oracle Linux yum server—something RHEL restricts to paid subscribers.

  • Built for Oracle Cloud: Oracle Linux is deeply integrated with Oracle Cloud Infrastructure (OCI), providing consistency across on-premises and cloud environments.
