Ụlọ ọrụ Oracle wepụtara mmelite atụmatụ nke abụọ maka kernel Ụlọ ọrụ anaghị emebi emebi kernel R5, edobere maka ojiji na nkesa Oracle Linux dị ka ihe ọzọ na ngwugwu ọkọlọtọ nwere kernel sitere na Red Hat Enterprise Linux. kernel dị maka ụlọ ọrụ x86_64 na ARM64 (aarch64). Isi mmalite kernel, gụnyere ndakpọ n'ime patches nke ọ bụla, bipụtara na ebe nchekwa Oracle ọha Git.

Ngwungwu kernel Enterprise enweghị ike imebi dabere na kernel Linux 4.14 (UEK R4 dabere na kernel 4.1), nke emelitere site na njirimara ọhụrụ, njikarịcha na ndozi, a na-anwalekwa maka ndakọrịta na ọtụtụ ngwa na-arụ ọrụ na RHEL, ma na-ahazi ya ka ọ rụọ ọrụ na ngwanrọ ụlọ ọrụ Oracle na ngwaike. Ngwunye nwụnye na src nwere kernel UEK R5U1 kwadebere maka Oracle Linux 7.5 na 7.6 (ọ nweghị ihe mgbochi iji kernel a na ụdị RHEL, CentOS na Linux Scientific).
