I'm using Eclipse Indigo and I'm following this tutorial, after I run the example project and get my HPROF file, I tried to open it (see 3.3 Use MAT in the link I gave), I just keep receiving 'Out of Memory' error. I checked the file generated and its size is about 350MB. So I edited the eclipse.ini file to add more memory (I changed -xmx to 1024m), also did the same for the java app in run->run configurations. But no mather what number I give to -xmx I'm still getting the same heap space error. Any ideas? or is there any other tool that I can use?
In my eclipse.ini I use the following settings:
-vmargs
-XX:PermSize=256m
-XX:MaxPermSize=256m
-Xms256m
-Xmx1024m
I am able to open big hprofs with some hundreds of megabytes.

My PlayFramework app always starts with only 256mb ram. Is there a way to increase the default ram?
I start my application with sbt run
Thanks in advance
I got this error java.lang.OutOfMemoryError: Java heap space
You can edit sbt\conf\sbtconfig.txt and set -Xmx1024M for sbt globally.
Problem sovled:
"C:\Program Files\Java\jdk1.8.0_144\bin\java.exe" -Dfile.encoding=UTF8 -Djline.terminal=none -Dsbt.log.noformat=true -Dsbt.global.base=C:\Users\USER\AppData\Local\Temp\sbt-global-pluginstub -Xms512M -Xmx1024M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=2048M -classpath C:\Users\User\.IntelliJIdea2018.3\config\plugins\Scala\launcher\sbt-launch.jar xsbt.boot.Boot "project ji_approvalmachine_processes" run
Its not generic solution. But you can use relative paths or enviroment variables instead of the absolute path.
I have spring app, with intelliJ (community edition), ant, tomcat 8.5. There is build.xml (ant) file that works for others, but in my case it gives me an error :java.lang.OutOfMemoryError: Java heap space.
I have already tried:
Creating setenv.bat (I'm on windows) set JAVA_OPTS=-server -Xmx1024m.
Then, setting CATALINA_OPTS/JAVA_OPTS/ANT_OPTS system env. variable to -Xms512m -Xmx1024m
Then in Configure tomcat(GUI) -> Java -> Initial memory pool and Maximum memory pool to 512 and 1024.
Then in idea.exe.vmoptions (intelliJ), changed -Xms to 512m and -Xmx to 1024m
But it keeps giving me an error about not enough heap space, while other app (spring mvc as well) works perfectly fine on the same computer with the same intelliJ and the same tomcat configuration (but with maven).
I will download JVisualVM to get better overview what is happening but in the meantime maybe someone could give me a tip what else I could try to fix it?

I have updated the jdev.conf file to include the following, but still receive the error:
AddVMOption -XX:MaxPermSize=512M
AddVMOption -Xmx512M
AddVMOption -Xms512M
Furthermore, this project opens just fine without issue on a colleague's computer, where the jdev.conf file -XX:MaxPermSize=512M switch is set to 256M and the other 2 switches are not present.
I've spent the afternoon playing with different settings, trying to discover the difference, and I am left stumped. Is there something I'm missing? When I try to bump the setting to higher memory limits, JDeveloper fails to start the Java machine (I suspect that is related to memory allocated to Java itself), though it shouldn't be necessary, as the app works fine on my coworker's computer with half the memory allocated to JDeveloper.
I faced the same issue and it get resolved with the help of below link :
Fixing java.lang.OutOfMemory Java Heap Space error in JDeveloper
Beside changing the configration fieles (jdev.conf and ide.conf) to have the commands
JDEV.CONF
AddVMOption -XX:MaxPermSize=256M
IDE.CONF
AddVMOption -Xmx768M
AddVMOption -Xms256M
See also this link:
Jdeveloper throwing Out of Heap Space error with SVN
Beside, stop versioning option for Jdeverlper as follow:
In JDeveloper -> Choose Versioning menu -> Choose Configure -> Uncheck “Versioning support for Subversion”
You can use some standalone SVN clients such as TortoiseSVN for
versioning
Egh. Simple, REALLY obvious solution that we just somehow overlooked. He is running an older version of JDeveloper. Installed that version, everything works.
When I'm using the graphical layout editor after 5-10 minutes of working I get the error "java heap size". I tried to increase size in eclipse.ini:
-Xms512m
-Xmx1024m
But it doesn't helped. Please tell me who encountered this problem and how to solve it?
Your eclipse.ini settings will take effect only if you change following:
Run -> External Tools -> External Tool
Configurations. go to configuration that u use, under jre tab -select option
Run in same JRE in workspace.
For more info on the topic have a look at this link. What are the best JVM settings for Eclipse?
If sometimes you get this error and smetimes doesn't then It might happens because RAM is being used by other processes which require large memory. Close all the other Applications/processes and try to start/load the eclipse. It works.
You can set this on the command line before running eclipse so that eclipse has more mem: How do I set Java's min and max heap size through environment variables?
I am writing an application on Java and it is throwing this error Java.lang.OutOfMemory Java Heap Space JDeveloper. I know that I can add java -Xmx512m to the command line to solve the problem. However, I need to run this application on JDeveloper. So, my Question is:
How to increase the size of the Heap on JDveloper?
Thank you,
Sami
Overview
The reasons JDeveloper can run out of memory include heap limits and large files.
Heap Limits
Files that control the amount of memory afforded to the JVM for JDeveloper upon startup, relative to the jdeveloper/ide/bin/ directory, include:
jdev.conf
ide.conf
Update these files as follows:
Quit JDeveloper.
Edit ide.conf.
Append the following
AddVMOption -Xms256M
AddVMOption -Xmx1024M
Edit jdev.conf.
Find the AddVMOption for the "heap size."
Change the values as follows:
AddVMOption -Xmx1024M
AddVMOption -XX:MaxPermSize=1024M
Large Files
JDeveloper naïvely attempts to parse files having known file extensions that are located in the project's root level directory. A sufficiently large file, such as a 3GB XML file, will cause problems. To work around this issue, create a subdirectory for the large data and move the file into it. JDeveloper will not try to find resources in arbitrary subdirectories.
Edit ${JDEV_HOME}\jdev\bin\jdev.conf and set the following options:
AddVMOption -Xmx512M
AddVMOption -XX:MaxPermSize=512M
then restart JDeveloper.
If your jDeveloper doesn't start after trying the above options, reduce the size from 1024 to 768 to 512
In 'ide.conf' change
AddVMOption -Xms256M
AddVMOption -Xmx1024M
to
AddVMOption -Xms256M
AddVMOption -Xmx768M
If this also doesn't start your jDeveloper, change it to
AddVMOption -Xms256M
AddVMOption -Xmx512M
And the same goes with 'jdev.conf'
