Indlela yokudibanisa ukuxhaswa kwabathengisi ababini kwi-SAP kwiiyure ze-12

Eli nqaku liza kukuxelela malunga neprojekthi enkulu yokuphunyezwa kwe-SAP kwinkampani yethu. Emva kokudityaniswa kweenkampani zeM.Video kunye ne-Eldorado, amasebe ezobugcisa anikwe umsebenzi ongewona umncinci - ukudlulisa iinkqubo zoshishino kwi-backend enye esekelwe kwi-SAP.

Ngaphambi kokuqala, besinesiseko se-IT esiphindwe kabini samatyathanga amabini evenkile, aquka iivenkile zokuthengisa ezingama-955, abasebenzi abangama-30 kunye namawaka amathathu amawaka erisithi ngosuku.

Ngoku ekubeni yonke into ilungile kwaye isebenza ngempumelelo, sifuna ukwabelana ngebali lokuba sikwazile njani ukugqibezela le projekthi.

Kulo mpapasho (owokuqala kwababini, ngubani owaziyo, mhlawumbi abathathu) siya kukubonisa ngedatha ethile kumsebenzi owenziweyo, ngakumbi onokuthi ufumane kwi-SAP ME intlanganiso eMoscow.

Iinyanga ezintandathu zokuyila, iinyanga ezintandathu zokubhala ikhowudi, iinyanga ezintandathu zokuphucula kunye novavanyo. KUNYE Iiyure ze12ukuqalisa inkqubo jikelele kwiivenkile ezili-1 kulo lonke elaseRashiya (ukusuka eVladivostok ukuya eKaliningrad).

Isenokuvakala ingekho ngqiqweni, kodwa siyenzile! Iinkcukacha phantsi kokusikwa.

Kwinkqubo yokudibanisa iinkampani zeM.Video kunye ne-Eldorado, sasijongene nomsebenzi wokuphucula iindleko kunye nokunciphisa iinkqubo zoshishino zeenkampani ezimbini ezahlukeneyo kwi-backend eyodwa.

Mhlawumbi le nto ingabizwa ngokuba yinhlanhla okanye i-coincidence - bobabini abathengisi basebenzisa iinkqubo ze-SAP ukulungiselela iinkqubo. Kwafuneka sijongane nokuphucula kuphela, kwaye hayi ngohlengahlengiso olupheleleyo lweenkqubo zangaphakathi zenethiwekhi ye-Eldorado.

Ngokusebenzayo, umsebenzi wahlulahlulwe wazizigaba ezithathu (eneneni ezine):

1. Yila “ephepheni” kunye nokuvunywa abahlalutyi bethu bezoshishino kunye nabacebisi be-SAP kwiinkqubo ezintsha (kunye nokuphuculwa kwezinto ezindala) kwiinkqubo ezikhoyo.

   Emva kokuhlalutya inani lezibonakaliso ze-backend esele isebenza kwiinkampani ezimbini, i-backend ye-M.Video yathathwa njengesiseko sokuphuhliswa kwenkqubo edibeneyo. Enye yeekhrayitheriya eziphambili apho ukhetho lwenziwa ngayo ukusebenza kakuhle kwenkampani iyonke, ingeniso enkulu kunye nenzuzo kwiindleko eziphantsi zokusebenza kweshishini.

   Uhlalutyo kunye nesigaba soyilo sithathe malunga neenyanga ezintandathu, iibhiliyoni zeeseli ze-nerve ezivela kwiintloko zesebe kunye neengcali zobugcisa, kwaye ezininzi, iilitha ezininzi zekofu zazinxilile.

2. Ukuphunyezwa ngekhowudi. Nanga amanani asekelwe kwiziphumo zeprojekthi:
   • Iindlela ezingama-2 ngosuku ezicwangcisiweyo kusetyenziswa imodyuli yolungiselelo.
   • Ngabasebenzisi abangama-38 ngaphambili nangasemva.
   • Iimpahla ezingama-270 kwiindawo zokugcina zeshishini elidibeneyo.

   Malunga neetshekhi ezingama-300 eziqhutywa yinkqubo ngosuku, ezithi emva koko zigcinwe ukuya kuthi ga kwiminyaka emihlanu ukubonelela abathengi ngesiqinisekiso, kunye neenjongo zophando lwemarike.

   Bala imivuzo, iimali ezihlawulwa kwangaphambili kunye neebhonasi zabasebenzi abangama-30 ngenyanga.

   Lo msebenzi wawubandakanya iqela leengcaphephe zezobugcisa ezingama-300 ezisebenze iinyanga ezilishumi. Ukusebenzisa izibalo ezilula ze-arithmetic, sifumana amanani amabini abonisa ngokucacileyo ubungakanani bomsebenzi owenziweyo: 90 indoda/iintsuku kunye… 000 iiyure zokusebenza.

   
   
   Okulandelayo - ukulungelelaniswa kweendlela zomntu ngamnye kwiimodyuli ze-SAP malunga nekhulu leendlela eziye zakhawuleziswa amaxesha amahlanu ukuya kwesithandathu ngokulungisa ikhowudi kunye nemibuzo kwisiseko sedatha.

   Kwiimeko zomntu ngamnye, sikwazile ukunciphisa ixesha lokwenziwa kwenkqubo ukusuka kwiiyure ezintandathu ukuya kwimizuzu elishumi ngokulungiselela imibuzo kwiDBMS.

3. Inqanaba lesithathu mhlawumbi lelona linzima kakhulu - ukuvavanya. Yayiquka imijikelo emininzi. Ukuze siphumeze, siye sahlanganisa iqela labasebenzi abangama-200, babandakanyeka kwiimvavanyo ezisebenzayo, zokudibanisa kunye nokubuyisela umva.

   Siza kuchaza iimvavanyo zomthwalo kumhlathi ohlukeneyo;

   Ngokusekelwe kwiziphumo zovavanyo ngalunye, ikhowudi kunye neeparitha ze-DBMS, kunye ne-database indexes ziphuculwe (siziqhuba kwi-SAP HANA, ezinye kwi-Oracle).

   Emva kwazo zonke iimvavanyo zomthwalo, malunga ne-20% ngaphezulu yongezwa kumandla okubalwa kwekhompyutha, kwaye uvimba omalunga nomthamo ofanayo (20%) wenziwa.
   Ukongeza, emva kokwenza le mijikelo ichazwe ngasentla, saqala ukuhlalutya iinkqubo ezili-100 ezisebenza kakhulu, ngokusekwe kwiziphumo esathi saphinda sayiphinda ikhowudi saza sawukhawulezisa umsebenzi wazo ngomyinge wezihlandlo ezihlanu (eziphinda ziqinisekise Ukubaluleka kokuhlenga-hlengisa kwakhona kunye nokwandisa ikhowudi).

   Uvavanyo lokugqibela olwenziwe "lunqunyulwe ngaphezulu". Indawo yovavanyo eyahlukileyo yenzelwe yona, ekhuphele iziko lethu ledatha elivelisayo. Senze "Sika ngaphezulu" kabini, ixesha ngalinye lithatha malunga neeveki ezimbini, apho silinganisa isantya sokusebenza okunje: ukutshintshela useto lwenkqubo ukusuka kwindawo yovavanyo ukuya kwindawo enemveliso, ukulayisha izikhundla ezivulekileyo zoluhlu lweempahla kunye namaxesha okungabikho imisebenzi.

4. Kwaye inqanaba lesine - ukuqaliswa ngqo emva kokuphumelela iimvavanyo. Umsebenzi wawu, ukuthetha ngokunyanisekileyo, kunzima: kwiiyure ze-12 ukutshintsha malunga neevenkile ze-955 kwilizwe lonke, kwaye kwangaxeshanye ungayeki ukuthengisa.

Ngobusuku bukaFebruwari 24-25, iqela leengcali ezilishumi zenkampani yethu zathatha "ukubukela" kwiziko ledatha, kwaye umlingo wenguqu waqala. Siza kuthetha ngayo ngokubanzi kwi-meetup yethu, kwaye emva koko siya kunikela inqaku lesibini kwiinkcukacha zobuchwepheshe bomlingo wethu we-SAP.

Iziphumo.

Ngoko ke, umphumo womsebenzi kwaba ukwanda kwezi zalathi ezifana:

• Umthwalo kwi-backend uphantse uphindwe kabini.
• Inani leetshekhi ngosuku landa ngama-50% ukusuka kwi-200 ukuya kwi-300 lamawaka.
• Inani labasebenzisi be-frontend lenyuka ukusuka kwi-10 lamawaka ukuya kwi-20 lamawaka.
• Kwimodyuli yokubala umvuzo, inani labasebenzi linyuke ukusuka kwi-15 lamawaka ukuya kwi-30 lamawaka abantu.

Siza kuthetha ngazo zonke iinkcukacha zobuchwepheshe kwintlanganiso yethu ye-SAP eMoscow, eya kwenzeka ngoJuni 6 kwiofisi ye-M.Video-Eldorado. Iingcali ziya kubelana ngamava abo okuphunyezwa. Ngokusekwe kwiziphumo zentlanganiso, iingcaphephe eziselula ziya kukwazi ukufumana i-internship ehlawulwayo kwinkampani ngethemba lokuqeshwa.

Ungafumana iinkcukacha ezithe vetshe kwaye ubhalise ku esi sixhobo
