Amathuluzi e-IT enhlangano yawo azoba nesidingo esikhulu esikhathini esizayo. Sethula uhlolojikelele lwe-Citrix Workspace Environment Manager, into ebalulekile ekwakheni indawo yokusebenza yedijithali. Kulesi sihloko sizobheka ukwakheka kanye namakhono ayinhloko omkhiqizo.
Isixazululo sezakhiwo
I-Citrix WEM ine-architecture yesisombululo se-client-server yakudala.
I-ejenti ye-WEM ye-WEM - ingxenye yeklayenti yesofthiwe ye-Citrix WEM. Kufakwe ezindaweni zokusebenza (ezibonakalayo noma ezingokoqobo, umsebenzisi oyedwa (VDI) noma abasebenzisi abaningi (amaseva amatheminali)) ukuze kuphathe indawo yomsebenzisi.
Imisebenzi yengqalasizinda ye-WEM yezinsiza zengqalasizinda - ingxenye yeseva ehlinzeka ngezinsizakalo zama-ejenti we-WEM.
Iseva yeMS SQL - Iseva ye-DBMS iyadingeka ukugcina isizindalwazi se-WEM, lapho kugcinwa khona imininingwane yokucushwa kwe-Citrix WEM.
Ikhonsoli yokuphatha ye-WEM - Ikhonsoli yokuphatha imvelo ye-WEM.
Masenze ukulungisa okuncane encazelweni yengxenye yezinsiza Zengqalasizinda ye-WEM kuwebhusayithi ye-Citrix (bona isithombe-skrini):
Iwebhusayithi isho ngephutha ukuthi izinsiza ze-WEM Infrastructure zifakwe kuseva yetheminali. Lokhu akulungile. I-ejenti ye-WEM ifakwe kumaseva etheminali ukuze ilawule indawo yomsebenzisi. Ukwengeza, akwenzeki ukufaka i-agnet ye-WEM neseva ye-WEM kuseva efanayo. Iseva ye-WEM ayidingi indima Yamasevisi Etheminali. Le ngxenye iyingxenye yengqalasizinda futhi, njenganoma iyiphi isevisi, kuyalulekwa ukuthi uyibeke kuseva ezinikele ehlukile. Iseva eyodwa ye-WEM enama-vCPU angu-4, i-RAM engu-8 GB ingakhonza abasebenzisi abangafika kwabangu-3000. Ukuqinisekisa ukubekezelelwa kwamaphutha, kufanelekile ukufaka okungenani amaseva amabili e-WEM endaweni.
Izici Eziyinhloko
Omunye wemisebenzi yabaphathi be-IT ukuhlela indawo yokusebenza yabasebenzisi. Amathuluzi okusebenza abasebenzi abawasebenzisayo kufanele abe seduze futhi amiswe njengoba kudingeka. Abaphathi badinga ukunikeza ukufinyelela kuzinhlelo zokusebenza (beka izinqamuleli kudeskithophu kanye nemenyu yokuQala, setha izinhlangano zamafayela), unikeze ukufinyelela kuzinsiza zolwazi (amadrayivu enethiwekhi yemephu), ukuxhuma amaphrinta enethiwekhi, ikhono lokugcina imibhalo yabasebenzisi phakathi nendawo, ukunikeza ikhono. ukuze abasebenzisi balungiselele indawo yabo futhi, okubaluleke kakhulu, ukuqinisekisa ulwazi lomsebenzisi olunethezekile. Ngakolunye uhlangothi, abalawuli banesibopho sokuphepha kwedatha, kuye ngezimo ezithile lapho umsebenzisi asebenza khona kanye nemibandela yokuhambisana nenqubomgomo yokulayisensa kwesofthiwe. I-Citrix WEM yakhelwe ukuxazulula lezi zinkinga.
Ngakho-ke, izici eziyinhloko ze-Citrix WEM:
- ukuphathwa kwemvelo yomsebenzisi

Ukuphathwa kwemvelo yomsebenzisi
Imaphi amakhono i-Citrix WEM ewahlinzekayo okuphatha izilungiselelo zokudala indawo yokusebenza yomsebenzisi? Isibalo esingezansi sibonisa ikhonsoli yokuphatha ye-Citrix Workspace Environment Manager. Isigaba Sesenzo sibonisa izenzo umlawuli angazisebenzisa ukuze alungiselele indawo yokusebenza. Okungukuthi, dala izinqamuleli zohlelo lokusebenza kudeskithophu nakwimenyu yokuqala (kuhlanganise nezinhlelo zokusebenza ezishicilelwe ngokuhlanganiswa ne-Citrix Storefront, kanye nekhono lokunikeza okhiye abashisayo bokwethula ngokushesha izinhlelo zokusebenza kanye nezixhumanisi zokubeka izinqamuleli endaweni ethile esikrinini) , xhuma amaphrinta enethiwekhi namadrayivu enethiwekhi, dala amadrayivu abonakalayo, phatha okhiye bokubhalisa, dala okuguquguqukayo kwemvelo, lungiselela ukumepha izimbobo ze-COM ne-LPT ngesikhathi, lungisa amafayela e-INI, sebenzisa imibhalo yohlelo (ngesikhathi se-LogOn, LogOff, Xhuma kabusha imisebenzi), phatha amafayela namafolda (dala, kopisha, susa amafayela namafolda), dala i-DSN Yomsebenzisi ukuze ulungise uxhumano kusizindalwazi esiseseva ye-SQL, lungisa izinhlangano zamafayela.
Ukuze kube lula ukuphatha, "izenzo" ezidaliwe zingahlanganiswa zibe Amaqembu Esenzo.
Ukuze usebenzise izenzo ezidaliwe, kufanele zabelwe iqembu lokuvikela noma i-KU yomsebenzisi wesizinda kuthebhu Yezabelo. Isibalo esingezansi sibonisa isigaba sokuhlola kanye nenqubo yokunikeza "izenzo" ezidaliwe. Ungabela Iqembu Lesenzo nazo zonke "izenzo" ezifakwe kulo, noma wengeze isethi edingekayo "yezenzo" ngazinye ngokuzihudula ukusuka kukholomu Etholakalayo kwesokunxele uye kukholomu Yabelwe kwesokudla.
Lapho unikeza "izenzo", udinga ukukhetha isihlungi, ngokusekelwe emiphumeleni yokuhlaziywa lapho uhlelo luzonquma isidingo sokusebenzisa "izenzo" ezithile. Ngokuzenzakalela, isistimu idala isihlungi esisodwa esithi Njalo Iqiniso. Lapho uyisebenzisa, zonke "izenzo" ezabelwe zihlala zisetshenziswa. Ukuze uthole ukuphathwa okuvumelana nezimo okwengeziwe, abalawuli badala izihlungi zabo esigabeni esithi Izihlungi. Isihlungi siqukethe izingxenye ezimbili: "Izimo" kanye "Nemithetho". Isithombe sibonisa izigaba ezimbili: ohlangothini lwesobunxele kukhona iwindi elidala isimo, futhi ngakwesokudla kunomthetho oqukethe izimo ezikhethiwe zokusebenzisa "isenzo" esifiselekayo.
Kunenani elikhulu kakhulu "lezimo" ezitholakala kukhonsoli - ezinye zazo kuphela ezikhonjisiwe emfanekisweni. Ngaphezu kokuhlola ubulungu kusayithi noma iqembu le-Active Directory, izimfanelo ze-AD ngazinye, izihlungi ziyatholakala ukuhlola igama le-PC noma ikheli le-IP, ukuhambisana nenguqulo ye-OS, ukuhlola ukuthotshelwa kwedethi nesikhathi, uhlobo lwezinsiza ezishicilelwe, njll.
Ngokungeziwe ekuphatheni izilungiselelo zendawo yokusebenza yabasebenzisi ngohlelo lokusebenza Lwesenzo, ikhonsoli ye-Citrix WEM inesinye isigaba esikhulu. Lesi sigaba sibizwa ngokuthi Izinqubomgomo namaphrofayili. Inikeza izilungiselelo ezengeziwe. Lesi sigaba siqukethe izigatshana ezintathu: Izilungiselelo Zemvelo, Izilungiselelo ze-Microsoft USV kanye nezilungiselelo zokuphatha iphrofayela ye-Citrix.
Izilungiselelo Zemvelo zihlanganisa inani elikhulu lezilungiselelo, eziqoqwe ngokwezibalo zaba amathebhu amaningana. Amagama abo ayazikhulumela. Ake sibone ukuthi yiziphi izinketho ezitholakalayo kubaphathi ukuze bakhe indawo yomsebenzisi.
Qala Ithebhu Yemenyu:
Ithebhu yedeskithophu:
Ithebhu ye-Windows Explorer:
Ithebhu Yephaneli Yokulawula:
Ithebhu yokushuna ye-SBCHVD:
Sizokweqa izilungiselelo kusukela esigabeni Sezilungiselelo ze-USV. Kuleli bhulokhi, izingxenye ze-Microsoft ezijwayelekile ziyalungiswa - Ukuqondisa Kabusha Kwefolda kanye Namaphrofayili Azulayo, afana nezilungiselelo zezinqubomgomo zeqembu.
Futhi isigatshana sokugcina sithi Izilungiselelo Zokuphathwa Kwephrofayela Ye-Citrix. Unesibopho sokumisa i-Citrix UPM yokuphathwa kwephrofayela yomsebenzisi. Kunezilungiselelo eziningi kulesi sigaba kunalezi ezimbili ezedlule zihlangene.

Ngezansi kunesithombe esinethebhu Yezilungiselelo Zokuphathwa Kwephrofayela Eyinhloko ye-Citrix kanye nohlu lwamathebhu atholakalayo angezwe ukuze kubhekwe kabanzi.
Ukuphatha okumaphakathi kwezilungiselelo zendawo yokusebenza yomsebenzisi akuyona into esemqoka ehlinzekwa yi-WEM. Imisebenzi eminingi ebalwe ngenhla ingafezwa kusetshenziswa izinqubomgomo zeqembu ezijwayelekile. Inzuzo ye-WEM ukuthi lezi zilungiselelo zisetshenziswa kanjani. Izinqubomgomo ezijwayelekile zisetshenziswa uma abasebenzisi bexhuma ngokulandelana ngokulandelana. Futhi kuphela ngemva kokuthi zonke izinqubomgomo sezisetshenzisiwe, inqubo yokungena iyaqedwa futhi ideskithophu itholakala kumsebenzisi. Uma izilungiselelo zinikwa amandla ngezinqubomgomo zeqembu, kuthatha isikhathi eside ukuzisebenzisa. Lokhu kwandisa isikhathi sokungena ngemvume. Ngokungafani nezinqubomgomo zeqembu, umenzeli we-WEM ushintsha uhlelo lokucubungula futhi asebenzise izilungiselelo kuchungechunge oluningi ngokuhambisana nangokuvumelanayo. Isikhathi sokungena komsebenzisi sincishiswe kakhulu.
Inzuzo yokusebenzisa izilungiselelo nge-Citrix WEM phezu kwezinqubomgomo zeqembu iboniswa kuvidiyo.
Bala ukuphathwa kwezinsiza
Ake sicabangele esinye isici sokusebenzisa i-Citrix WEM, okungukuthi ikhono lokuthuthukisa isistimu ngokuphatha ukusetshenziswa kwezinsiza (Ukuphathwa Kwezinsiza). Izilungiselelo zitholakala esigabeni Sokwenza Isistimu futhi zihlukaniswe ngamabhulokhi ambalwa:
- Ukuphathwa kwe-CPU
- Ukuphathwa Kwenkumbulo
- Ukuphathwa kwe-IO
- I-logoff esheshayo
- I-Citrix Optimizer
Ukuphathwa kwe-CPU kuqukethe amapharamitha wokuphatha izinsiza zokucubungula: ukukhawulela ukusetshenziswa kwensiza ngokujwayelekile, ukuphatha ama-spikes ekusetshenzisweni kwensiza yokucubungula, nokubeka phambili izinsiza ezingeni lesicelo. Izilungiselelo eziyinhloko zitholakala kuthebhu Yezilungiselelo Zomphathi we-CPU futhi ziboniswa esithombeni esingezansi.
Ngokuvamile, inhloso yemingcele icacile emagameni abo. Isici esijabulisayo yikhono lokuphatha izinsiza zokuphrosesa, i-Citrix ezibiza ngokuthi βsmartβ optimization - I-CPUIntelligent CPU optimization. Igama elinomsindo lifihla ukusebenza okulula kodwa okusebenzayo. Uma isicelo siqala, inqubo inikezwa ukusetshenziswa okuphezulu kakhulu kwe-CPU. Lokhu kuqinisekisa ukuqaliswa okusheshayo kohlelo lokusebenza futhi ngokuvamile kwandisa izinga lokunethezeka lapho usebenza nesistimu. Wonke βumlingoβ ukuvidiyo.
Kunezilungiselelo ezimbalwa ku-Memory Management kanye ne-IO Management section, kodwa ingqikithi yazo ilula kakhulu: ukuphatha inkumbulo kanye nenqubo ye-I/O lapho usebenza ngediski. Ukuphathwa kwememori kunikwe amandla ngokuzenzakalela futhi kusebenza kuzo zonke izinqubo. Lapho uhlelo luqala, izinqubo zalo zigcina i-RAM ethile yomsebenzi wazo. Njengomthetho, lesi sabelomali sikhulu kunalokho okudingekayo okwamanje - indawo yokugcina yenzelwe "ukukhula" ukuze kuqinisekiswe ukusebenza okusheshayo kwesicelo. Ukuthuthukisa inkumbulo kuhlanganisa ukukhulula inkumbulo kulezo zinqubo ebeziku-Idle State isikhathi esimisiwe. Lokhu kufezwa ngokuhambisa amakhasi ememori angasetshenzisiwe uwayise efayeleni lokupheja. Ukuthuthukiswa komsebenzi wediski kufinyelelwa ngokunikeza izinto eziza kuqala ezinhlelweni zokusebenza. Isithombe esingezansi sibonisa izinketho ezitholakalayo zokusebenzisa.
Ake sibheke isigaba se-Fast Logoff. Lapho ephuma ngokujwayelekile, umsebenzisi ubona izinhlelo zokusebenza zivaliwe, iphrofayela ikopishwa, njll. Uma usebenzisa inketho ye-Fast Logoff, umenzeli we-WEM uqapha ikholi ye-Log Off futhi anqamule iseshini yomsebenzisi - iyibeka kusimo sokunqamula. Kumsebenzisi, isikhathi siphela ngokushesha. Futhi uhlelo luhlala luqeda zonke izinqubo zomsebenzi "kungemuva". Inketho ye-Fast Logoff inikwe amandla ngebhokisi lokuhlola elilodwa, kodwa okuhlukile kunganikezwa.
Futhi ekugcineni isigaba, Citrix Optimizer. Abaphathi be-Citrix balazi kahle ithuluzi lokuthuthukisa "isithombe segolide" - I-Citrix Optimizer. Leli thuluzi lihlanganiswe ne-Citrix WEM 2003. Isibalo esingezansi sibonisa uhlu lwezifanekiso ezitholakalayo.
Abalawuli bangahlela izifanekiso zamanje, bakhe ezintsha, futhi babuke amapharamitha asethwe kuzifanekiso. Iwindi lezilungiselelo liboniswa esithombeni esingezansi.
Ikhawulela ukufinyelela ezinhlelweni zokusebenza
I-Citrix WEM ingasetshenziswa ukukhawulela ukwethulwa kohlelo lokusebenza, ukufakwa, ukwenziwa kombhalo, nokulayisha kwe-DLL. Lezi zilungiselelo ziqoqwa esigabeni Sokuphepha. Isibalo esingezansi sibonisa imithetho isistimu ehlongoza ukuyidala ngokuzenzakalelayo esigatshaneni ngasinye futhi ngokuzenzakalelayo yonke into ivunyelwe. Abalawuli bangabhala ngaphezulu lezi zilungiselelo noma bakhe ezintsha; emthethweni ngamunye, isenzo esisodwa kwezimbili siyatholakala - AllowDeny. Inombolo yemithetho edalwe kuyo ikhonjiswe kubakaki enegama lesigatshana. Isigaba Sokuphepha Kohlelo lokusebenza asinazo izilungiselelo zaso; sibonisa yonke imithetho evela ezigatshaneni zayo. Ngokungeziwe ekudaleni imithetho, abalawuli bangangenisa imithetho ekhona ye-AppLocker uma inhlangano yabo iyisebenzisa futhi baphathe izilungiselelo zemvelo kusuka kukhonsoli eyodwa.
Esigabeni sokuphatha Inqubo, ungakha uhlu olumnyama nolumhlophe ukuze ukhawulele ukwethulwa kwezinhlelo zokusebenza ngamagama wamafayela asebenzisekayo.
Ukuphatha izindawo zokusebenza zomzimba
Izilungiselelo zangaphambilini bezithakazelisa kithi ngokuphatha izinsiza kanye nemingcele yokudala indawo yokusebenza yomsebenzisi mayelana nokusebenza ne-VDI namaseva agcinayo. I-Citrix inikezela ngani ukuphatha izindawo zokusebenza oxhume kuzo? Amakhono e-WEM agqanyiswe ngenhla angasetshenziswa kuma-workstations aphathekayo. Ngaphezu kwalokho, ithuluzi likuvumela ukuthi "uguqule" i-PC yakho ibe "iklayenti elincane". Lolu shintsho lwenzeka ngokuvimbela abasebenzisi ukuthi bafinyelele kudeskithophu nokusebenzisa izici ezakhelwe ngaphakathi zeWindows ngokujwayelekile. Esikhundleni sedeskithophu, igobolondo lesithombe somenzeli we-WEM liyaqaliswa (i-ejenti efanayo ye-WEM isetshenziswa njengaku-VDIRDSH), kusixhumi esibonakalayo okuboniswa kuso izinsiza ze-Citrix. I-Citrix ine-software ye-Citrix DesktopLock, ekuvumela futhi ukuthi uguqule i-PC ibe yi-βTCβ, kodwa amandla e-Citrix WEM abanzi. Ngezansi kunezithombe zezilungiselelo eziyisisekelo ongazisebenzisa ukulawula amakhompyutha aphathekayo.
Ngezansi isithombe-skrini sokuthi indawo yokusebenza ibukeka kanjani ngemva kokuyiguqula ibe βiklayenti elincanyanaβ. Imenyu yokudonsela phansi Izinketho ibala izinto ezivumela umsebenzisi ukuthi enze ngokwezifiso imvelo ngendlela ayithandayo. Ezinye noma zonke zingasuswa kusixhumi esibonakalayo.
Abaphathi bangakwazi ukwengeza izixhumanisi ezinsizeni zewebhu yenkampani esigabeni esithi "Amasayithi", kanye nezinhlelo zokusebenza ezifakwe kuma-PC aphathekayo adingekayo emsebenzini wabasebenzisi esigabeni "Amathuluzi". Isibonelo, kuyasiza ukungeza isixhumanisi kuphothali yosekelo lomsebenzisi "Kumasayithi", lapho isisebenzi singakwazi ukudala ithikithi uma kunezinkinga zokuxhuma ku-VDI.
Isixazululo esinjalo asikwazi ukubizwa ngokuthi "iklayenti elincane" eligcwele: amandla alo anqunyelwe uma kuqhathaniswa nezinguqulo zezohwebo zezixazululo ezifanayo. Kepha kwanele ukwenza lula nokuhlanganisa isikhombimsebenzisi sokusebenza nohlelo, ukhawule ukufinyelela komsebenzisi kuzilungiselelo zesistimu ye-PC futhi usebenzise imikhumbi ye-PC egugile njengenye indlela yesikhashana yezixazululo ezikhethekile.
