The Oracle Linux and Virtualization Team is pleased to announce the general availability of Oracle Linux 7 Update 3 for x86-64 servers.

Users with a support subscription can download ISOs from My Oracle Support. ISO installation images can also be downloaded from Oracle Software Delivery Cloud. Individual RPM packages for Oracle Linux 7 Update 3 are available on the Oracle Linux yum server and the Unbreakable Linux Network (ULN).

This is the first Oracle Linux 7 ISO to include UEK Release 4 (UEK R4). Please note that new installations of Oracle Linux 7 Update 3 will install and boot the UEK R4 kernel by default. However, updates to existing Oracle Linux 7 environments require the user to explicitly install UEK R4 and will not automatically replace existing UEK R3 kernels.

Kernel Support with Oracle Linux 7 Update 3

The Oracle Linux 7 Update 3 ISO includes and installs two sets of kernel packages:
Unbreakable Enterprise Kernel (UEK) and Red Hat Compatible Kernel (RHCK).

The installation process configures the system to boot with UEK as the default kernel, and configures RHCK as an alternate kernel.

The Oracle Linux 7 Update 3 ISO contains the following kernel packages:

•           kernel-uek-4.1.12-61.1.18.el7uek (UEK R4u2 +errata)

•           kernel-3.10.0-514.el7

Oracle Linux 7 Update 3 continues to support, but does not ship with, the latest UEK R3u7 and later.

Application Compatibility

Oracle Linux maintains user space compatibility with Red Hat Enterprise Linux, which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on Oracle Linux 7 Update 3 with UEK R4 and no re-certifications are needed for applications already certified with RHEL 7 or Oracle Linux 7.

Notable in Oracle Linux 7 Update 3:

UEFI Secure Boot Support. This update allows you to install and use Oracle Linux 7 on systems that have enabled UEFI Secure Boot, which is fully supported on Oracle Linux 7 Update 3.

For more details on this and other new features and changes in Oracle Linux 7 Update 3, please consult the release notes in the Oracle Linux Product Documentation Library.

Oracle Linux can be downloaded, used and distributed free of charge and all updates and errata are freely available. For support, you decide which of your systems require a support subscription. This makes Oracle Linux an ideal choice for your development, testing and production systems. You decide which support coverage is the best for each of your systems individually, while keeping all of your systems up-to-date and secure. For customers with Oracle Linux Premier Support, you also receive access to zero-downtime kernel updates using Oracle Ksplice and support for Oracle OpenStack for Oracle Linux.
