[resolved] Could not create the Java virtual machine.

Anonymous — Sat, 16 Nov 2024 14:19:10 GMT

Hello,
I install TOS v2.4 on Vista with TalendOpenStudio-win32-x86.in file :
-vmargs
-Xms500m
-Xmx500m
-XXermSize=128m
-XX:MaxPermSize=128m
I can start TOS and create job, but when I run a job (even a simple job like tRowGenerator => tLogRow), I get the message:
Starting job simple at 17:21 26/06/2008.
Could not create the Java virtual machine.
Error occurred during initialization of VM
Could not reserve enough space for object heap
Job simple ended at 17:21 26/06/2008.
Remark: I can run the job in debug mode.
Thanks.

Hi dlrem,
prefer this conf:

-vmargs
-Xms40m
-Xmx500m
-XX:MaxPermSize=128m

Xms must not be same that Xmx
How much total memory do you have in your computer ?

Ok I test with your conf, but I have the same problem...
The computer has 2Mb RAM...

- go to menu Window > Preferences
- then go to category Talend > Run / Debug
finally change conf of Run job such as:
Xms128M
Xmx512M
I hope it will work 🙂

Normally it's because WinZozz added a java executable in WINDOWS/system32/.
Moving the JAVA_HOME/bin entry in the Path variable to the first position should solve the problem.

Hi,
please reduce the value for minimum memory:
-Xms1200m
to
-Xms500m
(for example)
Bye

Hi! Same problem, I tried to solve using your hints but no way.
OS WinXP SP3
TalendOpenStudio-win32-x86.ini:
-vmargs
-Xms40m
-Xmx500m
-XX:MaxPermSize=128m
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)
Path=C:\Programmi\Java\jre6\bin;
Talend Open Studio version TOS-Win32-r29643-V3.2.0RC1 (but same problem with 3.1.4 ...)
Error appears when I run jobs:
Could not create the Java virtual machine.
Error occurred during initialization of VM
Could not reserve enough space for object heap
or when I try to add a metadata in guessing schema:
Could not create the Java virtual machine.
Preview error. Some settings must be changed.
Note: Preview errors are generally due to a wrong encoding setting.
org.talend.designer.runprocess.shadow.ShadowFilePreview.preview(Unknown Source)
org.talend.repository.ui.utils.ShadowProcessHelper.getCsvArray(Unknown Source)
org.talend.repository.ui.wizards.metadata.connection.files.delimited.DelimitedFileStep2Form$PreviewProcessor.nonUIProcessInThread(Unknown Source)
org.talend.commons.ui.swt.thread.SWTUIThreadProcessor$1.run(Unknown Source)
but it's not an encoding issue ...
Thank you in advance.

Hello kevins
As Vincenzo vitale said, try to move the JAVA_HOME/bin entry in the Path variable to the first position should solve the problem.
Best regards

The problem is that the JVM cannot reserve the space.
The ini memory settings are only for Talend, not for the running job. You need to set those in the Preferences under Talend->Run and Debug, which, by default is set to Xmx 1024.
Try decreasing the memory setting in the Preferences and run it again. If that doesn't work, export the job as a script and try running it outside of the Studio via the Command Prompt.

Jandy,
thanks, that allowed the job to run fine.

Hi,
I am running TIS version 3.2.1 and have tried many combinations of the memory setting but still get :-
Could not create the Java virtual machine.
Error occurred during initialization of VM
Could not reserve enough space for object heap
I have 2.5Gb of memory.
Current settings are :-
-vmargs
-Xms256M
-Xmx1536M
-XX:MaxPermSize=128m
I want to be able to run the debugger, so exporting the job and running from the command line is not feasible.
One of the posts says :-
'Moving the JAVA_HOME/bin entry in the Path variable to the first position should solve the problem.'
but I do not know how to do this??
Can anyone help?

If your OS is Windows, Windows itself will always reserve HALF of all available memory for itself, leaving the other half for all applications. This means you may have significantly less memory available for the JVM than you might think.

I have the same issue since some days : I can't launch the jobs that I create, but I can launch those already created...

-Xms1024M
-Xmx2048M
- Java : jre6

Same issue, but I am pretty sure it is purely down to the fact that the max ammount that you tried to reserve is not actually available to the JVM. This did not work: "-Xms256m -Xmx1024m" but when I changed it to "-Xms256m -Xmx512m" that was fine (I used the -XX:+UseParallelGC garbage collector)
Try gradually reducing the Xms and Xmx and see what happens

It was the project properties who were incorrect, I change them to ""-Xms256m -Xmx1024m" and I can now create job without any problem.
