When i try to open eclipse, it displayes this errorr: "Could not create java virtual machine" . I already tried all solution said on internet or stackowerflow, but didnt work for me. Please help me. How can i solve that. ( win 10 64bit)
Can you please check heap size specified in vm argument while starting.My guess is your jvm is pointing jdk 32 bit and in your heap you have mentioned higher value.That is the main reason for it.
check in eclipse.ini all value are correct or not
-vm
C:/java/bin/javaw.exe
--launcher.XXMaxPermSize
256M
-vmargs
-Dosgi.requiredJavaVersion=1.7
-Xms40m

I am testing a simple recommender system built using Mahout in Eclipse.
If the preferences file is too big I am getting this error:

I have already read several messages about this issue and my eclipse.ini is the following
-startup

-Xmx6000m
-Xdock:icon=../Resources/Eclipse.icns
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts
Basically I added -Xmx6000m and changed -Xmx and MaxPermSize (both) to 3000m.
I am not very fluent in Java so I don't know if the settings are correct, but during the execution I can see something like
Heap size: 55M of total 3017M max 5996 mark 55M
Which seems to reflect the settings.
The weird thing is that I don't see much increase of the heap size during execution, also the free memory in my computer (mac os) is around 800M.
Where is the problem?
If the preferences file is smaller, everything works fine.
The eclipse.ini settings are only used for the Eclipse application.
When you Run a Java application from Eclipse you need to go to 'Run > Run Configurations'. Find your application in the Java application list. On the 'Arguments' tab enter your memory settings in the 'VM arguments' section.
Read Java Heap Space - How does -Xmx work exactly?

Java Heap is not the same for every system i think that in Windows for example the default java Heap is 60 Mb
I'm having issue with running my Eclipse with the following config:
eclipse.ini
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502

-XX:MaxPermSize=512M
-XX:+UseParallelOldGC
-XX:ParallelGCThreads=2
-XX:ThreadPriorityPolicy=1
-Xverify:none
-XX:-UseSplitVerifier
The above configuration works except when I add the lines I specified above. What could be the problem?
I am running eclipse from a Windows 7 (64-bit) machine with 4GB ram, although the JDK I specified in the path is 32-bit which works just fine. The only problem is if I add those additional config parameters.
There are two place in eclipse.ini that includes
--launcher.XXMaxPermSize
256m
make it
--launcher.XXMaxPermSize
128m
I had exactly the same problem, one day eclipse wouldn't open. Tried editing eclipse.ini to the correct java version 1.7, but still the same error. Eventually changed :
-Xms384m
-Xmx384m
...and all working.
it works for me after changing MaxPermSize=512M to MaxPermSize=256M
Change the below parameter in the eclipse.ini (which is in the same directory as eclipse.exe) to match one of your current Java version. Note that I also changed the maximum memory allowed for the eclipse process (which is run in a JVM). If you having multiple Java versions installed this can be happen. The below trick word for me.
-Xmx512m
-Dosgi.requiredJavaVersion=1.6
I cahanged this to,
-Xmx1024m
-Dosgi.requiredJavaVersion=1.7
Then It worked...
Reduce the memory size to Xmx512m and it works.

I deleted my eclipse.ini after non of the above worked for me.
I fully expected the next run (when it looked likely to work) to recreate it so I could compare but it did not.
So I can't tell what fixed it specifically.
an oddity I did have however was jdk 1.7 but when I ran
C:\Users\jonathan.hardcastle>java -version
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.7', but '1.6' is required.
Error: could not find java.dll
Error: could not find Java SE Runtime Environment.
i got the above.. so I (re?)installed jre 1.7 specifically and that went away.
This was not linked to my eclipse success directly.
--launcher.XXMaxPermSize
MaxPermSize=256m
-Xms512m
-Xmx1024m
replace with below one
--launcher.XXMaxPermSize
MaxPermSize=128m
-Xms256m
-Xmx512
m
You can also try closing other programs. :)
It's pretty simple, but worked for me. In my case the VM just don't had enough memory to run, and i got the same message. So i had to clean up the ram, by closing unnecessary programs.
Just add your JDK path in windows environment variable. This solves in my case
I had the same problem, I've fixed it very simple by updating my JDK version. If you don't have JDK installed or not updated, please Go here and install/update it. Mostly your problem will be fixed.
In my case reducing Xmx1024m to something smaller e.g Xmx512m make it works. So from all the responses (above and in similar other sites), it seems that you may try to massage/reduce the memory size.
I have added below line and its working fine.
-vm C:/Program Files/Java/jdk1.6.0_16/bin/javax.exe
-Xmx512m
-Dosgi.requiredJavaVersion=1.6
You can do a workaround as below:
Create a shortcut for eclipse and right click on the short cut and go to properties of the shortcut.
In the target box update the string:
-vm "C:\Program Files\Java\jdk1.6.0_07\bin"
the path will change according to your java installed directory.
So after changing the target string will be something like below.
D:\adt-bundle-windows-x86-20131030\eclipse\eclipse.exe -vm "C:\Program Files\Java\jdk1.6.0_07\bin"
Click apply and try clicking the Eclipse shortcut.
Try to open eclipse.ini and replace
-Xmx1024m
with
-Xmx512m
My java version is 1.7 as you can see below
-Dosgi.requiredJavaVersion=1.7
so i didn't modify that parameter.
This worked for me ;-)
For me it was a memory issue. If I run tomcat with my (large) webapp then try to start Eclipse, I get the Eclipse error. If I start Eclipse first, then start tomcat and my webapp, all works as expected.
Recently i encounter this issue and try all of the above method but none of them works for me.
Here is another Trick for to solve this error is
i just delete the eclipse configuration file and eclipse start working.. i don't know why but it works.
Maybe this helps someone else.
If Anybody Is using prior version then Jdk 8 update 20 and getting this Issue
Please Remove the following from eclipse.ini file
-XX:+UseStringDeduplication
As StringDeduplication was added in later version of JDK 8 in update 20
For StringDeduplication Clarification check this By Fabian Lange
https://blog.codecentric.de/en/2014/08/string-deduplication-new-feature-java-8-update-20-2/
I had also entered the path of MinGW complier for C++. After removing it, the error disappeared.
I tried several methods but didn't work. The only one that did is the one right at the bottom. I'll just list the other options I tried as well, for reference.
Some background, I migrated from Mars to Neon and copied over eclipse.ini almost exactly.
Reduce -XX:MaxPermSize and -Xmx
Like other answers have mentioned, progressively reduce these 2 flags (eg to 128m) and try again. If it still doesn't work at 128m then try other options below.
Find the offending flag by renaming eclipse.ini
Jon H's answer gave me a hint. Delete eclipse.ini (or rename it) and start eclipse. It should regen eclipse.ini and launch successfully (mine didn't regen eclipse.ini though eclipse launched fine).
If eclipse.ini did regen for you, then add each flag back one-by-one.
If not, revert the original eclipse.ini and remove each flag one-by-one until you've found the flag that causes an error.
For my case, I upgraded from Mars to Neon. The offending flag was -XX:+UseG1GC Removing this flag (and only this flag) worked for me. Setting back -Xmx and -XX:MaxPermSize to 1G worked for me as well.
It works for me after removing -XX:+UseParallelOldGC option from file.
Change target to specific installation file
like below
Target: D:\SoftWares\oepe-12.1.3.1-luna-maf-distro-win32-x86_64old\eclipse.exe -vm D:\delete\jdk1.7.0_67\bin\javaw.exe
I am using eclipse EE in ubuntu by downloading the .tar.gz file from eclipse website and extracting in my home directory. I set the -Xmx to 3072m in the eclipse.ini. Here it is:
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.1.R36x_v20100810
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-XX:MaxPermSize=256m
-Xms2048m
-Xmx3072m
But when I am trying to see my total memory by
Runtime.getRuntime().totalMemory()
It is returning 62193664 that is 59mb. I also tried to launch eclipse from terminal setting vmagrs, but nothing changed. I don't know what is happening. How can I set the heap size? My total ram is 4gb and I using 64bit Ubuntu with 64bit eclipse. Any information will be very helpful to me.
1) The Runtime.getRuntime().totalMemory() does not return the maximum allowed heap size.
2) I'm not sure how do you run Runtime.getRuntime().totalMemory() but I guess you do that from within your Eclipse in a Java application. In this case you execute the call in another JVM which does not inherit properties from your eclipse.ini file. If you want to determine the initial and max heap size for it you can go to Run->Run Configurations.... Click on your current run configuration and in the right pane click on the Arguments tab. There you may specify the VM arguments, e.g.:
-Xms64m
-Xmx1024m
Afterwards you may continue experimenting with the Runtime. eclipse.ini configures the resources for the Eclipse IDE not for the Java application that you run.
Cheers!
In short, Runtime.getRuntime().totalMemory() is useless, it returns the size of one GC generation.
This thread has an explanation: http://mail.openjdk.java.net/pipermail/hotspot-gc-use/2008-December/000318.html
Thank you. So the solution is setting VM Arguments from Run->Run Configurations in eclipse. I had set it to -Xms3072m -Xmx3072m and now the Runtime totalMemory() is returning 3087007744 that is 2944MB in 4gb ram with 64 bit Ubuntu 10.10 and 64 bit JVM.
I'm getting this error when I run or debug my GA/AI from MyEclipse:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
eclipse.ini looks like this:
-showsplash com.genuitec.myeclipse.product
--launcher.XXMaxPermSize 256m
-vmargs
-Xms128m
-Xmx512m
-Duser.language=en
-XX:PermSize=128M
-XX:MaxPermSize=256M
MyEclipse is called like this:
"C:\Program Files\MyEclipse 6.0\eclipse\eclipse.exe" -vm "C:\Program Files\MyEclipse 6.0\jre\bin\javaw.exe" -vmargs -Xms1448M -Xmx1448M
bumping the vm settings up from this:
"C:\Program Files\MyEclipse 6.0\eclipse\eclipse.exe" -vm "C:\Program Files\MyEclipse 6.0\jre\bin\javaw.exe" -vmargs -Xms80M -Xmx1024M
has had no effect. So I'm trying to get it to dump the heap to a file, but placing these:
-XX:+HeapDumpOnCtrlBreak
-XX:+HeapDumpOnOutOfMemoryError
in the Program arguments has had no effect. How do I get something to work with more memory usage analysis? jstack, for instance, is not currently available on Windows platforms. And using SendSignal has no effect that I can see.
There are a number of ways to get heap dumps. Here are some I've used:
-XX:+HeapDumpOnOutOfMemoryError should get you dump if you hit your OOM.
Connect with VisualVM (free) and use its GUI to force a heap dump
Use one of the many good commercial profilers (JProfiler, YourKit, ...)
Use jmap (see below) to force a dump from a running process
If you're running Java 6, jmap should work on Windows. This might be useful if you want to dump the heap and you haven't hit your OOM. Use Windows Task Manager to find the pid of your Java app, and in a console run this:
jmap -dump:format=b,file=c:\heap.bin <pid>
In addition to VisualVM, the Eclipse Memory Analyzer (also free) can help you analyze what's eating up all the space once you've got the dump.
-XX:+HeapDumpOnOutOfMemoryError should be put in "VM Arguments" not "Program Arguments"
You can monitor memory usages with JConsole.
The jstat also will help.
