Oracle Linux was created in 2006 to provide a Linux solution which was well-tested for enterprise products such as the Oracle Database, Middleware and applications, coupled with enterprise-level support. Oracle has been an active contributor to Linux since 1998, shipping the first ever commercial database on Linux and contributing multiple filesystems and feature enhancements. Our core focus is developing open source products and improving the stability and performance of the OS (see https://linux.oracle.com/ for more info). Most projects for our team are developed using C, python, and bash shell. Projects initiated or led by Oracle include core Linux components: btrfs, the next generation Linux filesystem; OCFS2, a general purpose filesystem; t10 DIF, enforcing data integrity throughout the IO stack; and RDS, a reliable datagram socket replacement for UDP on Infiniband fabrics. A comprehensive listing of our open source contributions can be found on oss.oracle.com and oss.oracle.com/git.Through our experience with engineered systems such as the flagship Exadata, and OCI we created an additional kernel option, the Unbreakable Enterprise Kernel (UEK). Supporting engineered systems required us to be more innovative with the Linux kernel, and UEK is a Linux kernel which combines mainline Linux performance with enterprise stability. UEK has secured world record database benchmarks for Oracle and provides the fastest execution environment for Oracle products. This kernel is refreshed from upstream Linux every 18 months, ensuring that new features can be used by these products in a timely fashion. See https://github.com/oracle/linux-uek for more info.As a member of the Oracle Linux Kernel Engineering team, you are expected to diagnose and troubleshoot customer reported problems seen in our Cloud, and on premise systems and develop code fixes to resolve those problems.
