heap-size

问题 I have a Spring Boot app deployend on Elastic Beanstalk using a single EC2 t2.micro instance (1GB RAM). I need to increase my app's JVM Heap size but I'm not being able to do so. The things I have tried are: Setting a JAVA_OPTS variable in the enviroment configuration in the EB console with the value -Xms512m -Xmx896m . Deploying the app with a Procfile in the project root folder what contains the following line: web: java -jar <relative-path-to-jar> -Xms512m -Xmx896m What else could I try?

问题 I want to use geotools(8.0-M3 currently, could be also 2.7.3) library in an Android app, using eclipse. (win7 prof, 4gb ram) But the build process crash, and i get following error Unhandled event loop exception Java heap space The java heap space problem should be solveable, but it seems there is more. (3gb should be enough, isn't it?) My final target is to be able to request a postgres postgis db on geoserver by OGC "web feature service" and "web map service". I already set the eclipse ini

问题 I have tomcat 6 server on windows xp ,And I start tomcat through console i.e. using startup.bat. AFAIK catalina.bat file is for windows so I am changing bat file for memory management.I don't have tomcat configuration window. Now I want to increase its heap size so My question is should I extend the existing JAVA_OPTS in catalina.bat file i.e. set JAVA_OPTS=%JAVA_OPTS% -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file="%CATALINA_BASE%\conf

问题 I have this peculiar problem with running a Processing application in IntelliJ IDEA. I want to save a large image and to do this I run in to the following exception: Exception in thread "Animation Thread" java.lang.OutOfMemoryError: Java heap space at java.awt.image.DataBufferInt.(DataBufferInt.java:75) at java.awt.image.Raster.createPackedRaster(Raster.java:467) at java.awt.image.DirectColorModel.createCompatibleWritableRaster(DirectColorModel.java:1032) at java.awt.image.BufferedImage.

问题 In my Spring Boot application I want to upload files into a MySql database. When I want to upload large files, I get java.lang.OutOfMemoryError: Java heap space exception. I get it with files about over 60Mb which seems normal because as I know 64Mb is the default heap size. I've run Tomcat8w.exe and on the Java tab I've added the following lines to the Java Options: -Xms512m -Xmx8192m -XX:PermSize=512m -XX:MaxPermSize=1024m Also, I've created a setenv.bat file into the bin folder with the

问题 In one of my activities I load a large number of bitmaps dynamically and show them in a GridView. There is risk of exceeding the heap size and crashing the app. I need a reliable way to know when heap size is growing too large, to stop loading the bitmap and start recycling the ones now being viewed at the moment. I tried using this function: public int memoryPercent(){ Double alloc=new Double(Runtime.getRuntime().totalMemory()/1048576); Double avail=new Double(Runtime.getRuntime().maxMemory(

问题 I get an error java.lang.OutOfMemoryError: Java heap space while executing logstash with a large dictionary of 353 mega bytes in translate filter. I use it to do a lookup on my input data. I tried to allow the JVM to use more memory (with java -Xmx2048m). suppose i do it wrong because it has no effect. I tested my config file with "smaller" dictionary and it worked fine. Any help please ? how to give logstash enough RAM to not die ? My config file looks like that : input { file { type =>

问题 I am trying to change the size of my jmeter(version 4) heap size from set HEAP=-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m to more as i have system with 64bit, 16GB RAM but unable to change it. i have tried a lot but nothing works for me. can any one here help me out with this issues. Thanks in Advance!! 回答1: JMeter version 4 comes with 1 GB of HEAP allocated by default , you can amend it like: set HEAP=-Xms1G -Xmx10G && jmeter.bat You can also locate the following line in jmeter.bat file: set

问题 I can set the Java Heap Size minimum and maximum by passing the parameters -Xms and -Xmx , respectively. I understand that the maximum flag is necessary to limit the space, but what's the reason for setting a minimum initial heap size? If the maximum is big enough, the space will increase? Or do i miss something? 回答1: Minimun size is set so that the JVM doesn't have to "resize" the heap space if it starts off too small. 回答2: Java will start with the minimum heap size and will try to avoid

问题 I want to increase the heap size of my Glassfish. For that, I know that I can go up to 4GB: java -Xmx4000M -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode) I tried to set in domain.xml file the -Xmx to 2GB: <jvm-options>-Xmx2000m</jvm-options> But I am getting the following error: asadmin> start-domain Waiting for ... to start .Error starting domain ...
