Ukunciphisa Isebenzo Ngokuphatha Kakhulu Kwe-Memory
Server ukulungiselela kwezikhathi kusemandleni kusidlala indima ephambili ekugcineni izinhlelo ezinamandla, ezihlakaniphileyo emhlabeni wamanje esebenza ngamadatha. Ngokuthi izicelo zombuso zakhula futhi izidingo zomsebenzisi zakhula, ukuzifundza konke okudingekayo ngendlela yokuphatha nokulungiselela imemori yomkluli kunconywa kakhulu abaprofeshini be IT nabagcwalisa izinhlelo. Le viki ephambili ihlola izindlela ezidebeleka nezephethe ukuthuthuka okwakhiwe ukuqasha isamba sakho sendlela yesikhathi, ukuqinisekisa ukusebenza kwempumelelo kunye nokuthembeka komali.
Izimboni ezintsha zihandlenza izenzo eziningi ngokulinganayo, ukusukela ekuphathiseni izimiso zomsebenzisi ukuya kuzo zodwa i-databases eziphucukelayo. Kuyadingeka imitholampilo yememori ngalinye lesi sikhathi, kungaba kube nomdawulo obuhle, izimboni zingahlupheka ngokushesha, okugcwalisa ukuchazwa kwemisebenzi futhi kufakazwe amaphutha esistimu. Masiyize into ebalulekile yokuhlengahlenga kwememori yesimemo futhi masithole konke kufanele kwenzeke.
Ukuziqonda Kwamajiko Wesimemo Wememori
Imemori Yomthwalo Ngaphandle Kwamajiko Wememori Evuliweyo
Umphakathi wamajiko wesimemo wememori ubandakanya imemori ye-RAM yomthwalo nezinhlobo zememori evuliweyo. Imemori ye-RAM yomthwalo inika indlela eyobulali ukuqashelana nodatha olusebenzayo nezenzo, ngelishwa imemori evuliweyo iyakhula imemori etholakala ngokusebenzisa indawo yediski. Ukuziqonda lokhu kubalulekile kakhulu ekunqumeni. Uma imemori yomthwalo isetshenziswa kabonakala, isistimu iselela ukushintshanisa udatha phakathi kwe-RAM nendawo yestorage ediskini, okungaholela ekuguqukeni kwezenzo.
Ukukhawuleza kwezinhlayiya zomsebenzisi kusenzo isinqumo esihle ngokusebenzisa izindlela ezivamile ekuphatheni kwememori, kanye nemaphashi, kanye nesithungu. Lezi zindlela zisebenza ngokuhlanganisa ukuqinisekisa ukufinyelela emshinini ngendlela efanelekile kanye nokusebenza kwezinhlayiya. Ngokuziqonda lezi ziphawu, ababhali bangeke bakhetha ngokuhle ngokwahlukaniswa kwememori kanye nezindlela zokuthuthelana.
Izindlela Zokwahlukaniswa Kwememori
Indlela okuhlelwa ngayo imemori yezinhlayiya ihluka kakhulu ekuphileni kwegunya. Ukubhalisa imemori ngendlela ethile kuvumela izinhlayiya ukuthatha imemori ngasikhathi sokusebenza, kodwa ukubhalisa imemori ngendlela echanekile kuyahlola imbangela yokugcina imemori ngasikhathi sokubhala. Izindlela zombili zinezimiso zakhe kanye nezimo eziphathelene nazo. Ukuziqonda lezi zindlela kuncike ekuboneni amathuba ethinta imemori engalutholakali kanye nezimali ezifanele.
Izindawo zokugcina kanye nezinhlekele zekeshi zihleza kabanzi ubunzima bokunika ngokugcinwa kwamabhloku ebukhazimbele ngaphambi kokufinyelela ngokushesha. Lezi zinhlekele zinakekela ukungabi nemiphambano futhi zizuze ubusetshiso besandla sonke sokugcina, zibenza kube yizinga eziphilayo zezinhlekele zasevafuleni.
Izindlela Zokunciphisa Ngokuhle
Ukubeka Amava Kwe-Memory Nokuchaneka
Ukunciphisa okuhle kwe-memory kwe-seva ikhula ngekubeka amava kanye nokuchaneka kabange. Ukusebenzisa izixhumanisi ezivimbela ukubeka amava kusiza ekuboneni izinhlobo zokusetshiso kwe-memory, izinqamuzi, nezinkinga ezinokwenzeka ngaphambi kokuba ziqedeze isebenza. Ukuchaneka okudala kwezinkcazo zememory kusiza abagcwalisi ukufunda ngendlela abasebenzi ngayo i-aplikasi kanye nezidingo zezindlela, kusiza ukuba kwenzeke ukunciphisa ngaphambili.
Iziphumo ezithe phambili zokubeka amava kusenzoza ukulandelela izikhathi ezibalulekile njengezimvavabo, ukusetshiso kwe-swap, kanye nedonsa yesandla. Lezi zinkcazo zisiza abagcwalisi ukufunda indlela abasebenzi ngayo i-aplikasi nezinhlelo ezahlukene ngesandla se-seva, kusiza ukuba kwenzeke ukunciphisa okuphathelene ngempela.
Imithetho Yokuphatha Inkondlo
Ukuphatha kahle kwesitshixo kubangela ubumnandi besikhumba se-server. Ukusebenzisa izindlela zokugcina inkondlo, njengegciniko le-zenzo-ngezenzo kanye negciniko elahlukene, kungaholela ekuvusekeni imfundo yesicelo futhi kunciphisa ukulahlekwa kwe-sikhumba. Ukuhlanjelana kwegciniko kufaka phakathi ukulungiselela kahle kwebanzi yegciniko, izinhombolo zokuphela kweyona, nokumelana kwemithwalo yokucima.
Izinkampani zasemva zegciniko zafana nezigaba ezihle ngaphezu kwegciniko kanye negciniko elingcono, ezingathatha khona izilungiselelo zegciniko ngokuzenzekelayo ngokulinganisa ngenkathi esebenzayo. Lezi zindlela ezihle zinesizo ekugcineni isikhumba ngendlela efanelekile futhi zihlale ihlinze idatha eqashelwayo ihlale ilandelayo.
Izimiso Eziphucayo Zokuphatha Isikhumba
Ukukhokha Kwesikhumba
Ukulahlekelwa kwezikhathi kuyinto ephathelene nomdaba wokuphatha izikhathi zomshini. Kutholakala uma izicelo ayikhipheli izikhathi ezinikezwayo ngendlela efanelekile, okubangela ukulahlekwa kwegunya elijulile. Ukusebenzisa izixhumanisi zobuchwepheshe bezikhathi nezinhlelo ezihle zokuthutha izicelo kusiza ekukhonzeleni le minyaka.
Imbizo yombhalo njalo, ukuphawula okunconyiwe, nezixhumanisi zokuphawula izikhathi ziduma indima eyisiseko ekutholeni nokukhonzela ukulahlekelwa kwezikhathi. Ngaphezu kwalokho, ukusebenzisa izindlela ezifanelekile yokushintsha imposiso nezindlela zokuhlenga izinto kusiza izicelo ibe yilapho inqanawa yezikhathi ngokuefficient njalo njengoba isebenza.
Ukulungiswa Kwesithembiso Segunya
Ukusithembisa igunya ngendlela ethembekile kusiza ukuthi igunya leseva libe lisebenziswe ngokuefficient kuzonke izicelo nezinsizakalo. Lokhu kufaka phakathi ukusetha amatheshwold ezigcwele, ukusebenzisa izinhlelo zokwahlukanisa ngendlela efanele, nokulungisa izimodi zesicelo. Ukuqonda izidingo zesicelo nezinhlotshwa zokusebenzisa kusiza ekubekeni indlela efanele yesithembiso.
Izixhobo zokugcina i-container kunye neempalindilizi yovavanyo ziphinde ziphinde zinika iindlela ezintsha zokuphatha ukunikezelwa kwezinto. Le zixhobo zinika umlawuli obalulekileyo kwinkqubo yokwahlula imemori kwaye zinesiza ekukhokeleni izicelo eziphethekayo ukuba zibonakale ngokupheleleyo imida yaseva.
Ukulungisa Iimpumelelo kunye Nokuhlela
Ukulungiswa Kweengqwalasela Zesistimu
Ukulinganiswa kakuhle kwesistimu kuthatha indima enkulu ekusikweni kwempumelelo wememori yeseva. Oku kufaka phawula ukulungisa iiparamitha zekernel, ukumisela isithuba esihlaziyiweyo, nokulungisa iiseto ezinxaleneyo ngezememori kwindalo yesistimu. Ukubeka kanjalo nokuvuselela kwezi zisetshenziswa kuyakusenela ukuba kufezekayo impumelelo njengeenguquko ezifuna.
Ukulungisa kumpumelelo kufaka phakathi iiseto zenkqubo yocingo, apho iiparamitha njengeezixhobo zokunxibelelana, inani leentambo, neebhafu zikhathaze kakhulu emehlweni yememori. Ukufumana ubungakanani obulungileyo phakathi kwezi zisetshenziswa kudinga ukuhlolwa nokugcoba kahle.
Imisebenzi yokuphepha ngokwesikhathi
Ukusekelwa kwezinhlelo zokulungisa okuphathelene kusiza ekugcineni imfundo ephelele yememori yeserver ngasikhathi. Kufaka phakathi ukucima kwegumbi ngemvula, ukuqala kabusha kwebhrawuza uma kudingeka, nokuvuselela kwisistimu ngokwesikhathi. Ukulungiswa okuphathelene kusinda ukuthetha kwemfundo futhi kusiza ekuboneni izinkinga ezinokuthuthuka kuqala.
Umbiko womsebenzi nezinhlelo zokuphatha utshintsho kusiza ekunikelweni umdalo wokulungiswa nokusiza ekulandeleni ubuchule bezindlela zokuphatha. Izimcheshiso eziphakeme zemfundo nokuvuselela kwezinhlelo zokulungiswa zihlinza izinqumo zokuphatha ziqashishe isidingo esishintsha sesistimu.
Imibuzo Evame Ukubuzwa
Ngani na ngikwazi ukubona izilahleko zememori kumaseva amabhrawuza?
Izilahlelo zememori zingabonwa ngendlela eyizilinganiso noma izindlela, kufaka phakathi izixhobo zokuhlola imemori, izisiko zokubukeka, nokuzinza izincwadi zomlando. Buka izimilo zokwandisa kumthetho wememori engaphansi kokulahleka, sebenzisa izixhobo ezithile zokuhlolwa, futhi enze ukubukeka okuphathelene kumfanekiso wememori ukuze ubone izilahlelo ezinokuthuthuka kuqala.
Uyini ukulungiselela kwegunya leseva kumasevisi okwenza kakhulu?
Ukulungiselela kufanelekile kubangelwa yizinkinga eziningi kanye nezidingo zomsebenti, izinhlobo zokusebenza, nokulungiselela kwesistimu. Ngokuvamile, kudingeka uvule amaginya aphumelela ngokuphelele futhi uthole ibafuli ephethilweyo yezikhathi zokusebenza kakhulu. Ukuchazwa nokubamba iqembu ngokuthuthukisa kusiza ekubeni uthole ukulungiselela okufanelekile kumsebenti wakho.
Kungakanjani isikhathi esifanele ukulungiselela kwegunya leseva kuqashelwe khona?
Kufanele ukulungiselela kwegunya leseva kube yinto evuthiwe noma ingekho yeyodwa kuphela. Kudingeka ukubamba iqembu kuqhubeka ngokudlulayo, kodwa ukubuyekeza okujulile nokulungiselela kufanele kwenzeke ngaphansi kweminyaka yonke. Ngaphezu kwalokho, qinisekisa ukuthi uqhubeka nokulungiselela ngokugcwele emva kokushintsha okukhulu komsebenti noma xa ushintshana nokuthuthukisa.
