Kugawa kwa Oracle Linux 7.7 kulipo

Kampani ya Oracle losindikizidwa kutulutsidwa kwa kugawa kwa mafakitale OracleLinux 7.7, yopangidwa kutengera nkhokwe ya phukusi Red Hat Enterprise Linux 7.7. Kutsitsa popanda zoletsa, koma mutalembetsa kwaulere, wogawidwa ndi kuyika chithunzi cha iso, 4.7 GB kukula, chokonzekera x86_64 ndi ARM64 (aarch64) zomangamanga. Kwa Oracle Linux komanso ndi lotseguka mwayi wopanda malire komanso waulere ku yum repository ndi zosintha zamabinala zomwe zimakonza zolakwika (errata) ndi zovuta zachitetezo.

Kuphatikiza pa phukusi la kernel kuchokera ku RHEL (3.10.0-1062), Oracle Linux imabwera ndi kumasulidwa m'chilimwe, Unbreakable Enterprise Kernel 5 (4.14.35-1902.3.2) imaperekedwa mwachisawawa. Magwero a kernel, kuphatikiza kugawanika kukhala zigamba pawokha, amapezeka pagulu Git repositories Oracle. Kernel imayikidwa ngati njira ina ya phukusi la kernel lomwe limaperekedwa ndi Red Hat Enterprise Linux ndipo limapereka zingapo. chowonjezera mwayi, monga kuphatikiza kwa DTrace ndikuthandizira bwino kwa Btrfs. Kupatula kernel, Oracle Linux 7.7 ndi yofanana ndi RHEL 7.7.

pakati chatsopano mawonekedwe a Oracle Linux 7.7 (pafupifupi zosintha zonse zomwe zatchulidwazi ndizodziwikanso RHEL 7.7):

  • NetworkManager yawonjezera kuthekera kokhazikitsa malamulo oyendetsera ndi magwero adilesi (njira yamalamulo) ndikuthandizira kusefa kwa VLAN pamakina a mlatho wa netiweki;
  • Zosinthidwa za NSS (Network Security Services), scap-security-guide 0.1.43, shadow-utils 4.6, gcc-libraries 8.3.1, linuxptp 2.0, tuned 2.11, chrony 3.4 phukusi. Anawonjezera python3 phukusi ndi Python 3.6 womasulira;
  • Pazotengera ndi zithunzi za mtundu wa UBI (Universal Base Image), thandizo lawonjezedwa pakusanthula zinthu kuti zigwirizane ndi mbiri yachitetezo cha SCAP Security Guide;
  • RHEL kernel yasiya kuthandizira ma Btrfs (kuti mugwiritse ntchito ma Btrfs, muyenera kugwiritsa ntchito ma maso a UEK R4 ndi UEK R5). Maphukusi okhala ndi MySQL achotsedwa pazolemba, zomwe ziyenera kutsitsidwa kuchokera kumalo osungiramo yum;
  • Kuzindikira kowonjezera kothandizira mawonekedwe a Simultaneous Multithreading (SMT) m'dongosolo ndikuwonetsa chenjezo lofananira kwa oyika zithunzi;
  • Dalaivala wosinthidwa wa NVMe/FC QLogic qla2xxxx;
  • Maluso oyesera amaperekedwa kuti ayesedwe mu UEK R5 kernel:
    • kulowetsa ndi kutumiza zotengera ku Systemd,
    • masanjidwe opangira zosungirako ngati zida za block ndi kusungira zinthu kwa pNFS,
    • Thandizo la DAX (kufikira mwachindunji pamafayilo akudutsa cache yamasamba osagwiritsa ntchito mulingo wa block block) mu ext4 ndi XFS,
    • Thandizo la OverlayFS,
    • HMM (Heterogeneous memory management) yogwiritsira ntchito zida zomwe zili ndi magawo awo owongolera kukumbukira,
    • No-IOMMU mode,
    • Cisco VIC InfiniBand ndi madalaivala a ibusnic_verbs,
    • kuthandizira kwa SR-IOV (Single-Root I/O Virtualization) mu dalaivala wa qlcnic,
    • Thandizo la TNC (Trusted Network Connect),
    • Thandizo la I/O pogwiritsa ntchito mizere ingapo (scsi-mq, Multi-queue) mu SCSI,
    • plugin yowongolera zosungirako kudzera pa libStorageMgmt API.
