Kutyhilwe i-Oracle Kutshanje ukukhutshwa kohlaziyo lwesibini olusebenzayo lweshishini elingenakuqhekeka Kernel R6, ibekelwe ukusetyenziswa kulwabiwo lwe-Oracle Linux njengenye indlela yokufumana iphakheji esemgangathweni ngeRed Hat Enterprise Linux kernel.
Ishishini elingenakuqhekeka Kernel 6 isekwe kwiLinux 5.4 (UEK R5 isekwe kwi-4.14 kernel), ethi iye yaphuculwa ngeempawu ezintsha, ukulungiswa kunye nokulungiswaKuye kwavavanywa ukuhambelana nezicelo ezininzi ezisebenza kwi-RHEL, kwaye ngokukodwa zilungiselelwe ukusebenza kunye ne-Oracle hardware kunye nesoftware yezoshishino.
Kwabo abangaziyo ngale nto I-Kernel iguqulwe ngu-Oracle, ibekwe njengeseti esezantsi I-Linux kernel, ibekwe kakuhle ukusetyenziswa kulwabiwo lwe-Oracle Linux njengenye indlela yokufumana iphakheji yekernel yeRed Hat Enterprise yesiqhelo.
IKernel yeShishini elingenakuqhekeka (UEK) ibonelela ngemithombo emitsha evulekileyo, Ukulungiselela okuphambili kunye nokhuseleko kwilifu nasemsebenzini.
YiKernel kernel enegunya kwiOracle Cloud kunye neNkqubo yeenjineli zeOracle, njengeOracle Exadata Database Machine kunye ne-Oracle Linux kwi-Intel kunye ne-AMD 64-bit okanye amaqonga e-Arm 64-bit.
Ukukhutshwa kwe-UEK 6 igcina iRed Hat ehambelana nokuhambelana kweKernel (RHCK) kwaye ayikhubazi naziphi na izinto ezinikwe amandla kwiRHCK. Iimpawu ezongezelelweyo zenziwe ukuba zixhase iimfuno eziphambili zomsebenzi kunye neepatches zisetyenziselwa ukuphucula ukusebenza kunye nokwenza ngcono i-kernel.
Ishishini elingenakuqhekeka Kernel R6U2 Amanqaku amatsha aphambili
Ukukhutshwa kweShishini elingenakuqhekeka Ukuhlaziywa kwe-6 yohlaziyo 2 kusekwe kwiLinux 5.4 Kernel kwaye ibandakanya ukulungiswa kwe-LTS ye-bug, kunye neepatches ezongezelelweyo zokuphucula ukusebenza okukhoyo kunye nokubonelela ngokulungiswa kwe-bug encinci kunye nokuphuculwa kokhuseleko. I-Oracle iyaqhubeka nokuphucula kunye nokusebenzisa iibhugi ezibalulekileyo kunye nokulungiswa kwezokhuseleko kwi-UEK R6. Olu hlaziyo lubandakanya amanqaku amatsha, ukusebenza okongeziweyo, kunye nokulungiswa kwe-bug kwiinkqubo ezahlukeneyo ezisezantsi.
Kule nguqulo intsha ibonisiweyo sinokufumanisa ukuba ngamaqela, kongezwe isilawuli senkumbulo esitsha esitsha ephawuleka kugqithiso lwe-slab accounting ukusuka kwinqanaba lememori kwiphepha le-kernel, okwenza ukuba kwabelwane ngamaphepha e-slab kumaqela ahlukeneyo, endaweni yokwabiwa kwee-slab ezahlukeneyo kwiqela ngalinye.
Indlela ecetywayo ivumela ukwanda kokusebenza ngokusetyenziswa kweslab, ukunciphisa ubungakanani bememori esetyenziselwa iibhloko ukuya kuthi ga kwi-50%, ukunciphisa kakhulu ukusetyenziswa kwememori kernel kunye nokunciphisa ukuqhekeka kwememori.
Olunye utshintsho olwahlukileyo inxulumene ngezixhobo zeMellanox ConnectX-6 Dx, kuba yongezwa umqhubi we-vpda omtsha ngenkxaso yesakhelo se-vDPA (vHost Data Path Acceleration), eyenza ukuba oomatshini bokwenyani basebenzise ukukhawulezisa izixhobo ezisekwe kwiVirtIO ye-I / O.
Kuyacaciswa ukuba ithuba lokulinga ukunciphisa umda ukwenziwa kwemisebenzi kuphunyezwa kwishedyuli yomsebenzi ibalulekile kwii-cores ezahlukeneyo ze-CPU, ukuvimba amajelo avuzayo ahambelana nokusebenzisa indawo ekwabelwana ngayo kwi-CPU.
Ye- Olunye utshintsho olwahlukileyo kolu hlobo lutsha:
- Ukuphuculwa okubonakalayo okunxulumene nenkxaso yezixhobo zeNVMe ukusukela kwiLinux kernel 5.9.
- Ukulungiswa okuhanjisiweyo kunye nezixhasi zeBtrfs, CIFS, ext4, NFS, OCFS2, kunye neenkqubo zefayile zeXFS.
- Ukuhlaziywa kwabaqhubi kubandakanya i-lpfc 12.8.0.5 (Broadcom Emulex LightPulse Fibre Channel Channel SCSI) 256 Gigabit mode for SCSI
- Ifayibha Channel, mpt3sas 36.100.00.00 (LSI MPT Fusion SAS 3.0), qla2xxx 0.02.00.103-k (QLogic Fiber Channel HBA).
- Yongeze inkxaso yokuvavanywa kweVPN Wireguard, ephunyezwe kwinqanaba lekernel.
- I-NFS yongeza inkxaso yokulinga yokukhuphela iifayile ngokuthe ngqo phakathi kweeseva njengoko kuchaziwe kwinkcazo yeNFS 4.2
Okokugqibela, ukuba unomdla wokwazi okungakumbi ngale nguqulo intsha ikhutshiweyo, ungajonga iinkcukacha Kule khonkco ilandelayo.
I-kernel iyafumaneka x86_64 kunye ne-ARM64 (aarch64) yoyilo. Imithombo ye-Kernel, kubandakanya ukwahlulahlula iziqwengana ezizimeleyo, zithunyelwa kwindawo yokugcina izinto kawonkewonke yeOracle
