Are these features available out of the box or exclusive to Oracle?

dTrace is Oracle exclusive, as no one else bothered.

Ubuntu has live kernel patching also, but with a different technology. And it's called different.

Ubuntu ships the live patching that was developed by SUSE and Red Hat.

After Oracle acquired the company that developed ksplice and took the technology private, SUSE started to develop kGraft[1] and Red Hat started to develop kpatch[2], and these were eventually merged and upstreamed[3] into Linux.
