UEK R7 includes Remote Direct Memory Access (RDMA) features that are provided in the upstream kernel, with the addition of Ksplice and DTrace functionality. RDMA enables direct memory access between two systems that are connected by a network. RDMA facilitates high-throughput and low-latency networking in clusters.

Starting with Oracle Linux 9, the process of installing Oracle-supported RDMA packages has been simplified through the use of new, user space packages and a dedicated ULN channel and yum repository for RDMA-related packages. For more information, see Installing and Upgrading Oracle-Supported RDMA Packages on Oracle Linux.

If you are running Oracle Linux 8, the process of installing Oracle-supported RDMA packages remains the same as in previous releases.
