  • 8-socket: Oracle Exadata X8M-8

  Note:

  Oracle Exadata System Software release 26.2.0 supports only Oracle Exadata systems based on RoCE Network Fabric.

• Minimum Oracle Exadata System Software version required on an existing system before updating to release 26.2.0:

  • Oracle Exadata System Software 25.1.9, September 2025

  • Oracle Exadata System Software 25.2.2, September 2025

  • Oracle Exadata System Software 26.1.0, June 2026

  Note:

  • Remove custom software packages (RPMs) before updating from Oracle Linux 8 to Oracle Linux 9. Oracle Linux 8 RPMs are not supported on Oracle Linux 9.

  • Ensure that all Exadata servers and the system that runs the update use SSH RSA keys with a minimum key length of 2048 bits. If this requirement is not met, regenerate and distribute SSH keys that meet the minimum key-length requirement before starting the update. The update cannot start until this requirement is met.

  • Exadata Live Update cannot perform an update across major Oracle Linux releases. When updating to Oracle Exadata System Software release 26.2.0, you must use a conventional update operation. After the update completes, you can use Exadata Live Update for eligible subsequent updates.

  • Use the patchmgr version included with the Oracle Exadata System Software release 26.2.0 software bundle.

  • On systems configured with virtual machines (VMs) on the database servers, you can upgrade the hypervisor (Oracle VM Server or Oracle Linux KVM) before or after the guest VMs. However, each VM guest must meet the minimum Oracle Exadata System Software requirement before being upgraded. Likewise, the hypervisor must meet the minimum Oracle Exadata System Software requirement before being upgraded.
