I-Quarkus: Izicelo Zesimanje Ezisebenzisa i-Helloworld Njengesibonelo esivela ku-JBoss EAP Quickstart (iyaqhubeka)

Sanibonani nonke - lokhu okuthunyelwe kwesihlanu ochungechungeni lwethu lwe-Quarkus! (Ngendlela, bukela i-webinar yethu "Lena iQuarkus - uhlaka lweJava yaseKubernetes". Sizokukhombisa ukuthi ungaqala kanjani ukusuka ekuqaleni noma udlulisele izixazululo esezilungile)

В okuthunyelwe kwangaphambilini sibheke ukwenza izinhlelo ze-Java zibe zesimanje sisebenzisa ubuchwepheshe obusekelwa yi-Quarkus (CDI ne-Servlet 3) sisebenzisa uhlelo lwe-helloworld olusuka endaweni yokugcina njengesibonelo. I-Red Hat JBoss Enterprise Application Platform (JBoss EAP) Quickstart. Namuhla sizoqhubeka nesihloko sesimanje futhi sixoxe ngendaba yokusebenzisa inkumbulo.

Isilinganiso sokusebenza siyisisekelo esiyisisekelo sanoma yikuphi ukuthuthukiswa, futhi ukubika ukusetshenziswa kwenkumbulo kuyingxenye ebalulekile yenqubo yokuhlaziya ukusebenza. Namuhla sizobheka amathuluzi okulinganisa afanelekile angasetshenziswa ukulinganisa ukuthuthukiswa okutholwe ngokwenza izinhlelo zokusebenza ze-Java zibe zesimanjemanje.

Ukuze uthole ulwazi olwengeziwe mayelana nokulinganisa ukusetshenziswa kwememori, bheka okokufundisa kwe-Quarkus okunesihloko Ukulinganisa Ukusebenza—Sikukala kanjani ukusetshenziswa kwenkumbulo?

Ngezansi sizovele sibonise indlela yokuqhathanisa idatha yokusetshenziswa kwenkumbulo phakathi kwezinhlobo ezintathu ezihlukene zezinhlelo zokusebenza (i-JBoss EAP, iphakheji ye-JAR, nesebenzisekayo) ngokuqoqa le datha ku-Linux kusetshenziswa izinsiza ze-pmap ne-ps.

JBoss EAP

Sethula isibonelo sohlelo lwe-JBoss EAP (bona isigaba esithi “Deploying helloworld” ku okuthunyelwe kwangaphambilini) bese ubheka inqubo yayo ye-PID (esibonelweni sethu yi-7268) usebenzisa umyalo olandelayo:

$ pgrep -lf jboss
7268 java

Qaphela. I--inketho ikuvumela ukuthi ukhiphe umugqa womyalo ophelele (okungukuthi: $ pgrep -af jboss).

Manje sisebenzisa i-PID 7268 kumiyalo ye-ps neye-pmap.

Kanje:

$ ps -o pid,rss,command -p 7268
PID RSS COMMAND 
7268 665348 java -D[Standalone] -server -verbose:gc -Xloggc:/home/mrizzi/Tools/jboss-eap-7.2.0/jboss-eap-7.2/standalone/log/gc.log -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=3M -XX:-TraceClassUnloading -Xms1303m -Xmx1303m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferI

Futhi kanje:

Iphakheji ye-JAR

Sethula uhlelo lwe-JAR (bona isigaba esithi “Run helloworld epakishwe ku-JAR” ku okuthunyelwe kwangaphambilini):

$ java -jar ./target/helloworld-<version>-runner.jar

Siphinde sibheke i-PID sisebenzisa umyalo we- pgrep (kulokhu sisebenzisa inketho echazwe ngenhla):

$ pgrep -af helloworld
6408 java -jar ./target/helloworld-<version>-runner.jar

Sisebenzisa i-ps ne-pmap ukukala ukusetshenziswa kwememori, kodwa manje ngenqubo engu-6408.

Kanje:

$ ps -o pid,rss,command -p 6408
  PID   RSS COMMAND
 6408 125732 java -jar ./target/helloworld-quarkus-runner.jar

Futhi kanje:

Ifayela elisebenzisekayo

Sethula elomdabu (bona isigaba esithi “Ukusebenzisa ifayela lendabuko le-helloworld elisebenzisekayo” ku okuthunyelwe kwangaphambilini):

$ ./target/helloworld-<version>-runner

Ake sibheke i-PID yayo futhi:

$ pgrep -af helloworld
6948 ./target/helloworld-<version>-runner

Bese sisebenzisa i-ID yenqubo engumphumela (6948) kumiyalo ye-ps neye-pmap.

Kanje:

$ ps -o pid,rss,command -p 6948

Sibheka i-RSS futhi sibona ukuthi ifayela elisebenzisekayo lithatha cishe u-20 MB wememori.

Ukuqhathanisa ukusetshenziswa kwenkumbulo

Ngakho-ke, sithole izinombolo ezilandelayo zokusetshenziswa kwememori:

• I-JBoss EAP - 650 MB.
• Iphakheji ye-JAR - 130 MB.
• Ifayela elisebenzisekayo - 20 MB.

Ngokusobala, ifayela elisebenzisekayo lithatha inkumbulo encane kakhulu.

Ake sifingqe okuthunyelwe 4 no-5

Kulokhu nokuthunyelwe kwangaphambilini, sibheke ukwenza izinhlelo ze-Java zibe zesimanjemanje sisebenzisa ubuchwepheshe obusekelwe ku-Quarkus (CDI ne-Servlet 3), kanye nezindlela ezihlukahlukene zokuthuthukisa, ukwakha nokusebenzisa izinhlelo ezinjalo. Sibonise indlela yokuqoqa idatha yokusetshenziswa kwememori ukuze sihlole ukuthuthukiswa okutholwe ukuthuthukiswa okunjalo. Lezi zihloko zikusiza uqonde ukuthi i-Quarkus isebenza kanjani nokuthi kungani ilusizo, noma ngabe ukhuluma ngohlelo olulula lwe-helloworld ezibonelweni zethu noma izinhlelo zokusebenza eziyinkimbinkimbi kakhulu zokuphila kwangempela.

Sizobuya emasontweni amabili nokuthunyelwe kokugcina mayelana neQuarkus - sizokubona lapho!

Eposini lethu lokugcina, sizobonisa indlela yokuhlanganisa i-AMQ Online ne-Quarkus ukuze kwakhiwe isistimu yesimanje ye-OpenShift yemiyalezo kusetshenziswa ubuchwepheshe obusha obusha bemiyalezo. Funda uqhubeke isixhumanisi.
