Re: [Pharo-users] how to increase memory for the jvm through jniport?

Hi Tudor,

it should be
jvmSettings runtimeSettings addOption: '-Xmx4000m'.
The options are added with exactly the same string which is used in command
lines.

You can check the value of an option by using java.lang.System.getProperty()
if it is a -Dname=value option. For -X options, it is not as simple as
that, see e.g.

 Hi Joachim,
 
 Do you happen to know how to set the Xmx for the JVM through JNIPort?
 
 I have this one right now, but I am not sure it's correct:
 
 jvmSettings := JVMSettings new.
 ...
 jvmSettings runtimeSettings addOption: 'Xmx4000m'.
 ^ JVM newWithSettings: jvmSettings
 
 Cheers,
 Tudor

[Pharo-users] how to increase memory for the jvm through jniport?

[Tudor Girba]

Hi,

When using JNIPort I am getting a java.lang.OutOfMemory: Java heap space.
To go around this, I would need to provide more memory to the JVM.

Essentially, I would like to provide the correspondent of a command line
like:
java -Xmx4000m

How should I do this?

Cheers,
Doru
