Feem ntau nws ua ntej tus nqi yog 1/4th ntawm koj lub cev nco los yog 1GB (qhov twg me dua). Kuj Java configuration xaiv (cov kab lus hais kom tsis txhob) tuaj yeem "outsourced" rau ib puag ncig hloov pauv nrog rau -Xmx, uas tuaj yeem hloov pauv ua ntej (lub ntsiab lus qhia qhov tshiab ua ntej ).
Tsuas yog li ntawd, lub neej ntawd JVM lub cim xeeb loj yog dab tsi?
Server JVM heap configuration ergonomics tam sim no tib yam li cov neeg siv khoom, tshwj tsis yog tias cov ua ntej siab kawg loj loj rau 32-ntsis JVMs yog 1 gigabyte, sib xws rau lub cev nco loj ntawm 4 gigabytes, thiab rau 64-ntsis JVMs yog 32 gigabytes, sib xws rau lub cev nco loj ntawm 128 gigabytes.
JVM nco tau faib li cas? Heap nco yog lub sijhawm khiav cov ntaub ntawv cheeb tsam los ntawm qhov nco rau tag nrho cov chav kawm java thiab arrays yog faib . Lub heap yog tsim thaum lub JVM pib thiab tuaj yeem nce lossis txo qhov loj me thaum daim ntawv thov khiav. Qhov siab tshaj plaws loj loj tuaj yeem teeb tsa siv -Xmx kev xaiv. Los ntawm lub neej ntawd, qhov siab tshaj plaws loj loj yog teem rau 64 MB.
Ib yam li ntawd, lub neej ntawd XMX Java tus nqi yog dab tsi?
Tus chij Xmx qhia qhov siab tshaj plaws kev faib pas dej ua ke rau a Java lub tshuab virtual (JVM), thaum Xms qhia txog thawj lub cim xeeb faib pawg. Xms chij tsis muaj tus nqi pib , thiab Xmx feem ntau muaj ib tus nqi pib ib 256 MB. Ib qho kev siv rau cov chij no yog thaum koj ntsib a java ua . lang.
XMS thiab XMX parameter hauv Java yog dab tsi?
Hauv tsab ntawv no, peb yuav pom txog Xms thiab Xmx parameter hauv java . - Xmx qhia qhov siab tshaj plaws nco loj rau Java virtual tshuab (JVM), thaum - Xms qhia lub cim xeeb thawj zaug. Nws txhais tau tias JVM yuav pib nrog Xms tus nqi ntawm lub cim xeeb thiab JVM yuav siv tau ntau tshaj ntawm JVM tus nqi ntawm lub cim xeeb.

Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
Dab tsi yog sparse kem Dab tsi yog qhov zoo thiab qhov tsis zoo?
Koj poob 4 bytes tsis yog ib zaug ib kab; tab sis rau txhua lub cell hauv kab uas tsis yog null. Qhov zoo ntawm SPARSE kem yog: Qhov tsis zoo ntawm SPARSE kem yog: SPARSE kem tsis tuaj yeem siv rau ntawm cov ntawv, ntext, duab, timestamp, geometry, geography lossis cov neeg siv cov ntaub ntawv teev tseg
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
