Oracle wrote in its update log: “In Oracle Linux 8, the core operating environment and related software packages for traditional Oracle Linux 8 servers are distributed by consolidating BaseOS and Applications Streams. BaseOS gives you the space to run your environment. ApplicationStreams provides a range of files that applications previously distributed in software collections and other products and programs that can be run in user space. “
