Oracle e lokolotse ntjhafatso ea bohlano ea tšebetso bakeng sa Unbreakable Enterprise Kernel R5, e behiloeng molemong oa ho sebelisoa phepelong ea Oracle Linux e le mokhoa o mong oa sephutheloana se tloaelehileng le kernel ho tsoa ho Red Hat Enterprise Linux. Kernel e fumaneha bakeng sa meralo ea x86_64 le ARM64 (aarch64). Mehloli ea kernel, ho kenyelletsa le karohano ea lipache ka bomong, e phatlalalitsoe sebakeng sa sechaba sa Oracle Git.
Unbreakable Enterprise Kernel 5 e ipapisitse le Linux kernel 4.14 (UEK R4 e ne e ipapisitse le kernel 4.1, mme UEK R6 e ne e ipapisitse le 5.4), e nchafalitsoeng ka likarolo tse ncha, ntlafatso le litokiso, 'me e lekoa ho lumellana le lits'ebetso tse ngata. e sebetsa ho RHEL mme e ntlafalitsoe ka ho khetheha bakeng sa ho sebetsa le software ea indasteri le lisebelisoa tsa Oracle. Liphutheloana tsa ho kenya le src tse nang le UEK R5U5 kernel li lokiselitsoe Oracle Linux 7 (ha ho na litšitiso tsa ho sebelisa kernel ena liphetolelong tse tšoanang tsa RHEL, CentOS le Scientific Linux).
Lintlafatso tsa mantlha:
- Khoutu e ikarabellang bakeng sa ho hlakola cache ea leqephe la memori ho hypervisor ea KVM e ntlafalitsoe, e ntlafalitseng ts'ebetso ea litsamaiso tse kholo tsa baeti le ho fokotsa nako ea bona ea ho qala.
- Litšitšili li lokisitsoe 'me lintlafatso li entsoe ho khoutu ea li-btrfs, CIFS, ext4, NFS, OCFS2 le XFS litsamaiso tsa lifaele.
- RDMA e ntlafalitse ts'ebetso ea li-switch tsa RDS (Reliable Datagram Sockets) ha ho ka ba le liphoso. E kenyellelitse lisebelisoa tse ncha tsa ho lokisa li-RDS tse sebelisang trace ho sebelisa eBPF le DTrace.
- Sebopeho sa /sys/kernel/security/lockdown se kenyellelitsoe ho li-securityfs ho laola Secure Boot Lockdown mode, e fokotsang phihlello ea basebelisi ho kernel le ho thibela UEFI Secure Boot bypass litsela.
- Bakhanni ba lisebelisoa ba ntlafalitsoe, ho kenyelletsa le mefuta e mecha ea bakhanni ba LSI MPT Fusion SAS 3.0, BCM573xx, Intel QuickData, Intel i10nm EDAC, Marvell PHY, Microsoft Hyper-V le QLogic Fiber Channel HBA.
