The swap space is located on disk, in the form of a partition or a file. Linux uses it to extend the memory available to processes, storing infrequently used pages there. We usually configure swap space during the operating system installation. But, it can also be set afterward by using the mkswap and swapon commands.
What is using swap space?
A computer has a sufficient amount of physical memory but most of the time we need more so we swap some memory on disk. Swap space is a space on a hard disk that is indawo yenkumbulo yomzimba. It is used as virtual memory which contains process memory images.
Can we clear swap space in Linux?
To clear the swap memory on your system, you simply need to cycle off the swap. Oku kuhambisa yonke idatha ukusuka kwimemori yokutshintsha kwakhona kwi-RAM. Kukwathetha ukuba kufuneka uqiniseke ukuba unayo i-RAM ukuxhasa lo msebenzi. Indlela elula yokwenza oku kukuqhuba 'simahla -m' ukubona ukuba yintoni esetyenziswayo kwi-swap nakwi-RAM.
Kwenzeka ntoni xa imemori itshintshiwe ngokupheleleyo?
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 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-16gb RAM idinga indawo yokutshintsha?
Ukuba unomthamo omkhulu we-RAM - 16 GB okanye njalo-kwaye awudingi i-hibernate kodwa ufuna indawo yediski, unokuhamba nencinci. 2 GB tshintsha isahlulo. Kwakhona, kuxhomekeke kwimemori engakanani eza kusetyenziswa yikhompyuter yakho. Kodwa luluvo olulungileyo ukuba nesithuba sokutshintsha nje xa kunokwenzeka.
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.
Ndiyilawula njani indawo yokutshintsha kwiLinux?
Kukho iinketho ezimbini xa kuziwa ekudaleni indawo yokutshintsha. Unokwenza isahlulo sokutshintsha okanye ifayile yokutshintsha. Uninzi lofakelo lweLinux luza kwabiwe kwangaphambili ngesahlulelo sokutshintsha. Le yibhloko ezinikeleyo yenkumbulo kwihard diski esetyenziswa xa i-RAM ebonakalayo igcwele.
Nditshintsha njani kwiLinux?
Amanyathelo asisiseko omawawathathe alula:
- Cima indawo yokutshintsha ekhoyo.
- Yenza isahlulelo esitsha sokutshintsha sobungakanani obufunwayo.
- Phinda ufunde itafile yolwahlulo.
- Qwalasela isahlulelo njengesithuba sokutshintsha.
- Yongeza isahlulelo esitsha/etc/fstab.
- Layita utshintsho.
Ndiyicoca njani indawo kwiseva yeLinux?
Ikhulula isithuba sedisk kumncedisi wakho we Linux
- Yiya kwingcambu yomatshini wakho ngokuqhuba i-cd /
- Sebenzisa sudo du -h –max-depth=1.
- Qaphela ukuba ngabaphi abalawuli abasebenzisa indawo eninzi kwidisk.
- cd kwelinye labalawuli abakhulu.
- Qhuba ls -l ukubona ukuba zeziphi iifayile ezisebenzisa indawo eninzi. Cima nayiphi na ongayifuniyo.
- Phinda amanyathelo 2 ukuya ku-5.
