I-Linux yahlula i-RAM yayo yokwenyama (inkumbulo yofikelelo ngokungacwangciswanga) kwiichucks zememori ezibizwa ngokuba ngamaphepha. Ukutshintshana yinkqubo apho iphepha lenkumbulo likhutshelwa kwindawo esele iqwalaselwe kwihard diski, ebizwa ngokuba sisithuba sokutshintshana, ukukhulula elo phepha lenkumbulo.
Ukutshintsha indawo kusebenza njani?
Indawo yokutshintsha isetyenziswa xa inkqubo yakho yokusebenza igqiba ukuba ifuna inkumbulo yomzimba kwiinkqubo ezisebenzayo kunye nemali ekhoyo (engasetyenziswanga) inkumbulo yomzimba ayonelanga.. Xa oku kusenzeka, amaphepha angasebenziyo asuka kwinkumbulo ebambekayo athi asiwe kwindawo yokutshintshiselana, ekhulula loo nkumbulo yomzimba ukwenzela ezinye izinto.
Ngaba ukutshintsha iLinux embi?
Ukutshintshana kuyinkumbulo yexesha likaxakeka; isithuba esibekelwe bucala ngamaxesha apho inkqubo yakho ifuna okwethutyana inkumbulo yomzimba ngaphezu kokuba ikhona kwi-RAM. Yiyo kuthathwa ngokuba “mbi” ngengqiqo yokuba iyacotha kwaye ayisebenzi, kwaye ukuba inkqubo yakho isoloko ifuna ukusebenzisa utshintshiselwano ngoko ngokucacileyo ayinayo inkumbulo yaneleyo.
Kutheni kufuneka ukutshintshanisa?
Ukutshintshana ku esetyenziselwa ukunika inkqubo igumbi, naxa i-RAM yomzimba yenkqubo sele isetyenzisiwe. Kwinkqubo eqhelekileyo yokucwangciswa, xa inkqubo ijongene noxinzelelo lwememori, utshintshiselwano lusetyenzisiwe, kwaye kamva xa uxinzelelo lwememori lunyamalala kwaye inkqubo ibuyela ekusebenzeni okuqhelekileyo, ukutshintshisana akusasetyenziswa.
Ngaba i-8GB RAM idinga indawo yokutshintsha?
Ke ukuba ikhomputha ine-64KB ye-RAM, isahlulelo sokutshintsha kwe 128KB iyakuba ngowona bungakanani. Oku kuthathela ingqalelo into yokuba ubukhulu bememori ye-RAM babuncinci kakhulu, kwaye ukwaba ngaphezulu kwe-2X ye-RAM yendawo yokutshintsha akuzange kuphucule ukusebenza.
...
Ngowuphi ubungakanani obufanelekileyo besithuba sokutshintsha?
| Isixa se-RAM efakwe kwisistim | Kucetyiswa indawo yokutshintsha |
|---|---|
| > 8GB | 8GB |
Kwenzeka ntoni xa imemori yokutshintsha igcwele?
Ukuba iidiski zakho azikhawulezi ngokwaneleyo ukuzigcina, ngoko ke inkqubo yakho inokugqiba ukubhuqa, kwaye uya amava okucotha njengoko idatha itshintshwa ngaphakathi nangaphandle kwinkumbulo. Oku kuya kubangela umqobo. Okwesibini ukuba kungenzeka ukuba uphelelwe yinkumbulo, okukhokelela kububi kunye nokuphazamiseka.
Kutheni ukusetyenziswa kokutshintshana kuphezulu kangaka?
Ipesenti ephezulu yokutshintshwa kosetyenziso iqhelekile xa iimodyuli ezibonelelweyo zisebenzisa kakhulu idiski. Ukusetyenziswa kokutshintsha okuphezulu kunokuba uphawu lokuba inkqubo ifumana uxinzelelo lwenkumbulo. Nangona kunjalo, inkqubo ye-BIG-IP inokufumana ukusetyenziswa kokutshintsha okuphezulu phantsi kweemeko eziqhelekileyo zokusebenza, ngakumbi kwiinguqulelo zamva.
Wenza ntoni uSwapoff kwiLinux?
tshintsha ikhubaza ukutshintshana kwizixhobo ezikhankanyiweyo kunye neefayile. Xa iflegi inikezelwe, ukutshintshiselana kuvaliwe kuzo zonke izixhobo zokutshintsha ezaziwayo kunye neefayile (njengoko zifunyenwe kwi /proc/swaps okanye /etc/fstab).
Zeziphi iingenelo ezimbini zokutshintshana?
Ezi zibonelelo zilandelayo zinokufunyanwa kusetyenziso olucwangcisiweyo lokutshintsha:
- Ukuboleka ngexabiso eliphantsi:
- Ukufikelela kwiiMarike eziNtsha zeMali:
- Ukuthintela uMngcipheko:
- Isixhobo sokulungisa ukungangqinelani kwe-Asethi-Liability:
- Utshintshiselwano lunokusetyenziswa ngenzuzo ukulawula ukungahambelani koxanduva lwe-asethi. …
- Umvuzo owongezelelweyo:
Yintoni ukutshintshanisa kuchaza ngomzekelo?
Ukutshintshana kubhekisa kutshintshiselwano ngezinto ezimbini nangaphezulu. Umzekelo, kwidatha yokucwangcisa inokutshintshwa phakathi kwezinto ezimbini, okanye izinto zinokutshintshwa phakathi kwabantu ababini. Ukutshintshana kunokubhekisa ngokuthe ngqo: Kwiinkqubo zekhompyuter, uhlobo oludala lolawulo lwenkumbulo, olufana nepheyiji.
Ngaba ndifuna ukutshintsha kwiseva?
Ewe, udinga indawo yokutshintsha. Ukuthetha ngokubanzi, ezinye iinkqubo (ezifana ne-Oracle) aziyi kufakwa ngaphandle kokutshintsha indawo ekhoyo ngobuninzi obaneleyo. Ezinye iinkqubo zokusebenza (ezifana ne-HP-UX - kwixesha elidlulileyo, ubuncinane) zabela indawo yokutshintsha kwangaphambili ngokusekelwe kwinto esebenzayo kwinkqubo yakho ngelo xesha.
