Oracle rakafukurwa Munguva pfupi yapfuura kuburitswa kweyechipiri kunoshanda kunatsurudzwa kweiyo Isingaputsike Enterprise Kernel R6, yakamira kuti ishandiswe muOracle Linux kugovera seimwe nzira kune yakajairwa package neRed Hat Enterprise Linux kernel.
Isingachinjiki Enterprise Kernel 6 yakavakirwa paLinux 5.4 (UEK R5 yaive yakavakirwa pa4.14 kernel), iyo yakagadziriswa nezvitsva, optimizations, uye kugadzirisaYakave yakaedzwawo kuenderana neakawanda mafomu anomhanya paRHEL, uye yakagadziridzwa zvakanyanya kushanda neOracle Hardware uye software yeindasitiri.
Kune avo vasingazive nezve izvi Kernel yakagadziridzwa naOracle, yakamisikidzwa senge yepamusoro seti Linux kernel, yakamira yekushandisa muOracle Linux kugovera seimwe nzira kune yakajairwa Red Hat Enterprise Linux kernel package.
Isingachinjiki Enterprise Kernel (UEK) inopa yazvino yakavhurwa sosi matsva, kiyi optimizations uye chengetedzo yegore uye pa - nzvimbo nzvimbo mabasa.
Ndiyo Linux kernel iyo inopa Oracle Cloud uye Oracle Injiniya Systems, senge Oracle Exadata Dhatabhesi Mashini uye Oracle Linux pane Intel uye AMD 64-bit kana Arm 64-bit mapuratifomu.
UEK Kuburitswa 6 inochengetedza Red Hat Inoenderana Kernel kuenderana (RHCK) uye haina kudzima chero maficha anogoneswa muRHCK. Zvimwe zvinowedzerwa zvinogoneswa kutsigira makiyi anoshanda anodikanwa uye zvigamba zvinoshandiswa kuvandudza mashandiro uye kugadzirisa kernel.
Main nyowani maficha easingaputsike Enterprise Kernel R6U2
Isingachinjiki Enterprise Kernel Kuburitswa 6 Kwidziridzo 2 yakavakirwa paLinux 5.4 Kernel uye inosanganisira inokwira kumusoro kweLTS bug fixes, iine mamwe matinji ekuvandudza mashandiro aripo uye nekupa zvimwe zvidiki zvigadziriso zvebug uye zvigadziridzo zvekuchengetedza. Oracle inoenderera nekuvandudza uye nekushandisa yakakosha bugs uye ekuchengetedza gadziriso kuUEK R6. Iyi yekuvandudza inosanganisira akati wandei maficha, akawedzera mashandiro, uye gadziriso inogadziriswa pane akasiyana masisitimu.
Mune iyi vhezheni nyowani yakaratidzwa tinogona kuwana izvo kumakungu, new slab memory controller yakawedzerwa izvo zvinozivikanwa nekuchinjiswa kweslab accounting kubva padanho repamusoro rendangariro kuenda padanho rechinhu chekernel, zvichiita kuti zvikwanisike kugovana mapeji echi slab mumapoka akasiyana, pane kugovera akapatsanurwa masirabhu eecheka rimwe nerimwe.
Maitiro akataurwa inobvumidza kuwedzera kugona kwekushandisa kweslab, kudzikisira saizi yendangariro inoshandiswa kumabhuroko kusvika pa50%, zvakanyanya kudzora kernel ndangariro yekushandisa uye kudzikisa ndangariro kupatsanurwa.
Imwe shanduko inomira pachena ane hukama neMellanox ConnectX-6 Dx zvishandiso, nekuti yakawedzerwa mutyairi mutsva wevpda ane rutsigiro rweiyo vDPA fomati (vHost Data Path Kuwedzeredza), iyo inogonesa michina chaiyo kushandisa VirtIO-yakavakirwa Hardware kumhanyisa yeI / O.
Izvo zvakare zvakasimbiswa izvo mukana wekuyedza kudzikamisa kuenzanisirwa kwekuitwa kwemabasa kunoitwa mune iyo schedulerator yebasa yakakosha pane akasiyana maCUU cores, kuvhara nzira dzinodonha dzakabatana nekushandisa yakagovaniswa cache pane iyo CPU.
Of the dzimwe shanduko dzinomira pachena yeiyi vhezheni itsva:
- Yakavandudzwa inovandudzwa inoenderana nerutsigiro rweNVMe zvishandiso kubvira Linux 5.9 kernel.
- Mafambiro akagadziriswa uye zvigadziriso zveBtrfs, CIFS, ext4, NFS, OCFS2, uye XFS mafaira masisitimu.
- Yakagadziridzwa madhiraivha anosanganisira lpfc 12.8.0.5 (Broadcom Emulex LightPulse Fiber Channel SCSI) 256 Gigabit modhi yeSCSI
- Fiber Channel, mpt3sas 36.100.00.00 (LSI MPT Fusion SAS 3.0), qla2xxx 0.02.00.103-k (QLogic Fiber Channel HBA).
- Wakawedzera rutsigiro rwekuyedza rweVPN Wireguard, inoitwa padanho rekernel.
- NFS inowedzera rutsigiro rwekuyedza rwekunanga faira kuteedzera pakati pemaseva sekutsanangurwa kwayakaitwa muNFS 4.2
Chekupedzisira, kana iwe uchifarira kuziva zvakawanda nezve iyi nyowani vhezheni yakaburitswa, unogona kutarisa ruzivo Mune inotevera chinongedzo.
Iyo kernel inowanikwa yeX86_64 uye ARM64 (aarch64) zvivakwa. Zvinyorwa zveKernel, kusanganisira kupaza kuita zvigamba, zvinotumirwa kuOracle's Git yeruzhinji nzvimbo.
