Oracle tau tshaj tawm Unbreakable Enterprise Kernel R5U2

Oracle tuam txhab tso tawm thib ob feature hloov tshiab rau lub kernel Unbreakable Enterprise Kernel R5, positioned rau siv nyob rau hauv lub Oracle Linux faib raws li ib tug lwm txoj rau cov txheej txheem pob nrog lub ntsiav los ntawm Red Hat Enterprise Linux. Lub kernel muaj rau x86_64 thiab ARM64 (aarch64) architectures. Kernel qhov chaw, suav nrog kev tawg mus rau hauv ib tus neeg thaj ua rau thaj, luam tawm hauv Oracle public Git repository.

Lub Unbreakable Enterprise Kernel 5 pob yog raws li cov ntsiav Linux 4.14 (UEK R4 yog raws li 4.1 kernel), uas tau hloov kho nrog cov yam ntxwv tshiab, kev ua kom zoo thiab kho, thiab tseem raug sim rau kev sib raug zoo nrog feem ntau cov ntawv thov uas khiav ntawm RHEL, thiab tshwj xeeb tshaj yog ua haujlwm nrog Oracle muaj software thiab kho vajtse. Kev teeb tsa thiab src pob nrog UEK R5U1 kernel npaj rau Oracle Linux 7.5 thiab 7.6 (tsis muaj qhov cuam tshuam rau kev siv cov ntsiav no hauv cov qauv zoo sib xws ntawm RHEL, CentOS thiab Scientific Linux).

Ntsiab kev txhim kho:

• Patches tau raug xa mus nrog kev siv PSI (Pressure Stall Information) subsystem, uas tso cai rau koj los txheeb xyuas cov ntaub ntawv hais txog lub sijhawm tos kom tau txais ntau yam kev pabcuam (CPU, nco, I / O) rau qee yam haujlwm lossis cov txheej txheem hauv ib pawg. . Siv PSI, cov neeg siv chaw ua haujlwm tuaj yeem kwv yees qhov tseeb ntawm cov txheej txheem thauj khoom thiab cov qauv qeeb piv rau Load Nruab Nrab;
• Rau cgroup2, lub cpuset resource controller tau qhib, uas muab cov txheej txheem rau kev txwv qhov kev tso kawm ntawm cov haujlwm ntawm NUMA nco ntawm thiab CPUs, tso cai rau kev siv cov peev txheej nkaus xwb uas tau teev tseg rau pawg neeg ua haujlwm los ntawm cpuset pseudo-FS interface;
• Lub ktask lub moj khaum tau siv los ua kom sib luag ua haujlwm hauv cov ntsiav uas siv cov peev txheej CPU tseem ceeb. Piv txwv li, siv ktask, parallelization ntawm kev khiav hauj lwm kom tshem tau ntau yam ntawm cov nplooj ntawv nco lossis txheej txheem cov npe ntawm inodes tuaj yeem teeb tsa;
• Hauv DTrace ntxiv kev txhawb nqa rau pob ntawv ntes ntawm libpcap siv qhov kev txiav txim tshiab "pcap(skb, proto)" Piv txwv li "dtrace -n 'ip::: xa { pcap((void *)arg0, PCAP_IP); }'";
• Los ntawm cov kernel tshiab nqa hla kho nyob rau hauv qhov kev siv ntawm btrfs, CIFS, ext4, OCFS2 thiab XFS cov ntaub ntawv systems;
• Los ntawm kernel 4.19 nqa hla kev hloov pauv cuam tshuam txog kev txhawb nqa rau KVM, Xen thiab Hyper-V hypervisors;
• Hloov tshiab ntaus ntawv tsav tsheb thiab nthuav kev txhawb nqa rau NVMe drives (hloov los ntawm kernels 4.18 rau 4.21 tau raug xa mus);
• Cov kev hloov kho tau raug siv los ua kom zoo rau kev ua haujlwm ntawm ARM platforms.
