I-Linux ihlukanisa i-RAM yayo ebonakalayo (inkumbulo yokufinyelela okungahleliwe) ibe yizicucu zememori ezibizwa ngokuthi amakhasi. Ukushintshanisa kuyinqubo lapho ikhasi lememori likopishelwa khona endaweni elungiselelwe kusengaphambili ku-hard disk, ebizwa ngokuthi i-swap space, ukuze kukhululwe lelo khasi lememori.
Ngabe ukushintsha indawo kusebenza kanjani?
Isikhala sokushintshana sisetshenzisiwe lapho isistimu yakho yokusebenza inquma ukuthi idinga inkumbulo engokwenyama ngezinqubo ezisebenzayo kanye nenani lenkumbulo etholakalayo (engasetshenzisiwe) engokwenyama ayanele.. Uma lokhu kwenzeka, amakhasi angasebenzi asuka enkumbulweni ebonakalayo abe esehanjiswa endaweni yokushintshana, kukhululwe leyo nkumbulo yomzimba kwezinye izinto.
Ingabe ukushintshanisa i-Linux embi?
Ukushintshanisa kuyinkumbulo ephuthumayo; isikhala esibekelwe eceleni sezikhathi lapho isistimu yakho idinga okwesikhashana inkumbulo engokwenyama kunaleyo onayo ku-RAM. Kunjalo kuthathwa ngokuthi “kubi” ngomqondo wokuthi ayisheshi futhi ayisebenzi kahle, futhi uma isistimu yakho idinga njalo ukusebenzisa ukushintshana ngakho-ke kusobala ukuthi ayinayo inkumbulo eyanele.
Kungani kudingeka ukushintshanisa?
Ukushintshanisa kuyinto esetshenziselwa ukunikeza izinqubo igumbi, noma ngabe i-RAM yesistimu isivele isetshenzisiwe. Ekucushweni okujwayelekile kwesistimu, lapho isistimu ibhekene nokucindezela kwenkumbulo, ukushintsha kuyasetshenziswa, futhi kamuva lapho ukucindezela kwenkumbulo kunyamalala futhi uhlelo lubuyela ekusebenzeni okujwayelekile, ukushintshaniswa akusasetshenziswa.
Ingabe i-RAM engu-8GB idinga isikhala sokushintshwa?
Ngakho-ke uma ikhompuyutha ibino-64KB we-RAM, ukuhlukaniswa kwe-swap I-128KB kungaba usayizi olungile. Lokhu kwacabangela iqiniso lokuthi osayizi benkumbulo ye-RAM ngokuvamile babebancane kakhulu, futhi ukwaba ngaphezu kwe-RAM engu-2X yesikhala sokushintshana akuzange kuthuthukise ukusebenza.
...
Ingakanani inani elilungile lesikhala sokushintshanisa?
| Inani le-RAM efakwe ohlelweni | Isikhala sokushintsha esinconyiwe |
|---|---|
| > 8GB | 8GB |
Kwenzekani uma inkumbulo yokushintshanisa isigcwele?
Uma amadiski akho engasheshi ngokwanele ukuba aqhubeke, isistimu yakho ingase igcine ishaya ngamandla, futhi thola ukwehla njengoba idatha ishintshwa ngaphakathi nangaphandle kwenkumbulo. Lokhu kungaholela enkingeni. Okwesibili kungenzeka ukuthi ungase uphelelwe inkumbulo, okuholela ekuhlakanipheni nokuphahlazeka.
Kungani ukusetshenziswa kokushintshana kuphezulu kangaka?
Amaphesenti aphezulu okusetshenziswa kokushintshana avamile lapho amamojula anikeziwe enza ukusetshenziswa kanzima kwediski. Ukusetshenziswa kokushintshashintsha okuphezulu kungase kube uphawu lokuthi isistimu ibhekene nokucindezeleka kwenkumbulo. Nokho, isistimu ye-BIG-IP ingase ihlangabezane nokusetshenziswa kokushintshashintsha okuphezulu ngaphansi kwezimo ezivamile zokusebenza, ikakhulukazi ezinguqulweni zakamuva.
Yenzani i-Swapoff ku-Linux?
ukushintsha ikhubaza ukushintshanisa kumadivayisi namafayela acacisiwe. Uma i- -a ifulegi inikezwa, ukushintshanisa kuyacishwa kuwo wonke amadivaysi namafayela okushintshaniswa aziwayo (njengoba atholakala ku-/proc/swaps noma /etc/fstab).
Yiziphi izinzuzo ezimbili zokushintshanisa?
Izinzuzo ezilandelayo zingatholwa ngokusetshenziswa okuhlelekile kokushintshanisa:
- Ukuboleka Ngezindleko Eziphansi:
- Ukufinyelela Ezimakethe Zezezimali Ezintsha:
- Ukuvimbela Ubungozi:
- Ithuluzi lokulungisa Ukungafani Kwesibopho Sempahla:
- Ukushintshanisa kungasetshenziswa ngokunenzuzo ukulawula ukungafani kwesibopho sempahla. …
- Imali Engenayo Eyengeziwe:
Kuyini ukushintshanisa kuchaza ngesibonelo?
Ukushintshanisa kubhekisela ekushintshaneni kwezinto ezimbili noma ngaphezulu. Isibonelo, ekuhleleni idatha ingase ishintshwe phakathi kwezinto ezimbili eziguquguqukayo, noma izinto zingashintshwa phakathi kwabantu ababili. Ukushintshashintsha kungabhekisa ku-: Ezinhlelweni zamakhompiyutha, uhlobo oludala lokuphatha inkumbulo, olufana nokupheja.
Ingabe ngidinga ukushintshanisa kuseva?
Yebo, udinga ukushintsha isikhala. Uma sikhuluma ngokujwayelekile, ezinye izinhlelo (ezifana ne-Oracle) ngeke zifakwe ngaphandle kokushintshana kwesikhala esikhona ngenani elanele. Amanye amasistimu wokusebenza (afana ne-HP-UX - esikhathini esedlule, okungenani) abela kuqala isikhala sokushintshwa ngokusekelwe kulokho okusebenzayo kusistimu yakho ngaleso sikhathi.
