Further information on Oracle Linux 8

For more details about these and other new features and changes, please consult the Oracle Linux 8 Update 1 Release Notes and Oracle Linux 8 Documentation.

Oracle Linux can be downloaded, used, and distributed free of charge and all updates and errata are freely available. Customers decide which of their systems require a support subscription. This makes Oracle Linux an ideal choice for development, testing, and production systems. The customer decides which support coverage is best for each individual system while keeping all systems up to date and secure.

Customers with Oracle Linux Premier Support also receive support for additional Linux programs, including Gluster Storage, Oracle Linux Software Collections, and zero-downtime kernel updates using Oracle Ksplice.

Application Compatibility

Oracle Linux maintains user-space compatibility with Red Hat Enterprise Linux (RHEL), which is independent of the kernel version that underlies the operating system. To minimize impact on interoperability during releases, the Oracle Linux team works closely with third-party vendors for hardware and software that have dependencies on kernel modules.
