Oracle wuxuu siidaayay Kernel Enterprise Unbreakable R5U2

Shirkadda Oracle la sii daayay update feature labaad ee kernel-ka Kernel Enterprise Aan La jabin karin, oo loo qoondeeyey in loogu isticmaalo qaybinta Oracle Linux si loogu beddelo xirmo caadi ah oo leh kernel-ka Red Hat Enterprise Linux. Kernel-ku wuxuu diyaar u yahay x86_64 iyo ARM64 (aarch64) qaab-dhismeedyada. Ilaha kernel-ka, oo ay ku jiraan kala qaybsanaan balastar gaar ah, la daabacay gudaha kaydka Oracle Git ee dadweynaha.

Kernel Enterprise Unbreakable 5 wuxuu ku salaysan yahay kernel-ka Linux 4.14 (UEK R4 waxay ku salaysan tahay 4.1 kernel), kaas oo lagu cusboonaysiiyay sifooyin cusub, hagaajin iyo hagaajin, waxaana sidoo kale lagu tijaabiyay inay la jaanqaadi karaan inta badan codsiyada ku shaqeeya RHEL, waxaana si gaar ah loogu wanaajiyay inay la shaqeyso Oracle software-ka warshadaha iyo qalabka. Rakibaadda iyo xirmooyinka src ee leh UEK R5U1 kernel diyaarisay loogu talagalay Oracle Linux 7.5 iyo 7.6 (ma jiraan wax caqabado ah oo loo isticmaalo kernel-kan noocyada la midka ah ee RHEL, CentOS iyo Linux Scientific).

Furaha horumar:

• Xirmooyinka waxaa lagu wareejiyay hirgelinta nidaamka hoose ee PSI (Cadaadiska Stall Information), kaas oo kuu ogolaanaya inaad falanqeyso macluumaadka ku saabsan waqtiga sugitaanka si aad u hesho ilo kala duwan (CPU, xusuusta, I/O) ee hawlaha qaarkood ama habraacyada kooxeed . Isticmaalka PSI, dadka isticmaala meelaha bannaan waxay si sax ah u qiyaasi karaan heerka culeyska nidaamka iyo qaababka hoos u dhaca marka la barbar dhigo Celceliska Load;
• Cgroup2, kontoroolka kheyraadka cpuset ayaa karti u leh, kaas oo bixiya habka lagu xaddidayo meelaynta hawlaha NUMA nodes memory iyo CPUs, taas oo u oggolaanaysa isticmaalka kaliya ee khayraadka lagu qeexay kooxda hawsha iyada oo loo marayo cpuset pseudo-FS interface;
• Qaab dhismeedka ktask ayaa la hirgeliyay si loo barbar dhigo hawlaha kernel-ka ee cuna ilaha muhiimka ah ee CPU. Tusaale ahaan, isticmaalka ktask, isbarbardhigga hawlgallada si loo nadiifiyo tirada bogagga xusuusta ama habaynta liiska inodes waa la abaabuli karaa;
• Gudaha DTrace ayaa lagu daray Taageerada qabashada xirmada iyadoo la adeegsanayo libpcap iyadoo la adeegsanayo ficilka cusub "pcap(skb,proto)" Tusaale ahaan "dtrace -n 'ip :: dir {pcap((void *)arg0, PCAP_IP); }";
• Laga soo bilaabo kernel-ka cusub qaaday hagaajinta hirgelinta btrfs, CIFS, ext4, OCFS2 iyo nidaamka faylka XFS;
• Laga soo bilaabo kernel 4.19 qaaday isbeddelada la xidhiidha taageerada KVM, Xen iyo Hyper-V hypervisors;
• La cusboonaysiiyay Dareewalada aaladaha iyo taageerada la ballaariyay ee darawallada NVMe (isbeddelka kernels 4.18 ilaa 4.21 ayaa la wareejiyay);
• Hagaajinta ayaa lagu dabaqay si kor loogu qaado waxqabadka aaladaha ARM.
