Oracle says its release version is not a branch of Red Hat.

For the past two or three years, Oracle has been selling Oracle Enterprise Linux, a Red Hat Enterprise Linux-based release that is supported by Oracle, But Oracle's Linux director said there is a major difference between the two, therefore, Oracle is not a branch of Red Hat.

Oracle Enterprise Linux is Binary compatible with Red Hat Enterprise Linux, that is, software that can run on Red Hat can also run on Oracle.

However, Wim Coekaerts, Oracle's Linux Engineering director, said that Oracle Enterprise Linux is not considered a copy of Red Hat. The most important thing for Linux distributions is to provide users with high-quality operating systems, "We don't want to create a new release version different from Red Hat. The problem is about support, not the software." Oracle said that its idea is to strengthen Linux, rather than creating one from scratch. The biggest difference between Oracle release and Red Hat is OCFS (Oracle Cluster File System) file System and Xen-based OracleVM virtualization technology.
