How does Oracle support RHEL3 and RHEL4?

Oracle Unbreakable Linux FAQ より

Oracle fully supports RHEL3U8 and onward through the Unbreakable Linux Support program. Unbreakable Linux Network (ULN) will offer a channel for RHEL3U8 patches, which users will be able to subscribe to. Users will be able to run up2date rpm for RHEL3 and download all patches including security erratas, whether released from Red Hat or provided by Oracle. Basic and Premier support customers can also call Oracle support 24x7 and get patches for specific issues on RHEL3.

Oracle supports all existing installations of RHEL3. Oracle makes rpms available for all the patches and updates and all changes are published. If RHEL3U9 is released, everything new since U8 will be made available through ULN. Oracle will provide rpms for all the packages that were changed in U9.
