Tau nce Daim Ntawv Thov Server JVM heap loj
- Nkag mus rau Daim Ntawv Thov Kev Pabcuam Kev Tswj Xyuas Server.
- Niag rau JVM xaiv.
- Kho qhov kev xaiv -Xmx256m. Qhov kev xaiv no teeb tsa JVM heap loj.
- Tsim qhov kev xaiv -Xmx256m rau tus nqi siab dua, xws li Xmx1024m.
- Txuag qhov chaw tshiab.
Yuav ua li cas yog tias JVM nco puv?
Java cov khoom nyob hauv thaj chaw hu ua heap. Lub heap yog tsim thaum JVM pib thiab tuaj yeem nce lossis txo qhov loj thaum daim ntawv thov khiav. Thaum lub pob zeb puv tag, khib nyiab tau sau Lub sijhawm khaws cov khoom khib nyiab uas tsis siv lawm raug tshem tawm, yog li ua qhov chaw rau cov khoom tshiab.
Yuav ua li cas nce JVM heap loj hauv IBM WebSphere?
1. Hauv WebSphere lub vev xaib, xaiv Servers -> Server Hom -> WebSphere daim ntawv thov servers -> Server Infrastructure -> Java thiab Txheej Txheem Kev Tswj -> txheej txheem txhais. 3. Nyob rau hauv General Properties section, muab 256 rau "thawj heap loj" thiab 1024 rau "qhov loj tshaj heap ".

Nco tseg: qhov no yog qhov zoo nkauj me me thiab koj tau txais qee cov khoom siv thiab cov xov tooj uas lub cim xeeb ntau. Yog koj muaj peev xwm yuav tau me ntsis ntxiv nws yuav ua rau koj lub neej yooj yim dua.
Vim li cas JVM siv lub cim xeeb ntau heev?
Java kuj yog ib hom lus siab heev Cov Hom Phiaj-Oriented programming lus (OOP) uas txhais tau hais tias thaum daim ntawv thov code nws tus kheej yooj yim dua los tswj, cov khoom uas tam sim no yuav siv nco ntau ntxiv.
