increase java heap space

HI,

How do I increase java heap space? I searched around and found some other questions about this in the forum but unfortunately I didn't understand the responses. Do I need to put some code directly in my processing sketch to set the minimum/maximum?

One post said something about adding this: Xms528m -Xmx1000m but...I don't know where I should add it to.

I'm using Mac os 10.6.6

Thanks very much.

appreciate it.

hello,

i don't have my mac with me today to check exactly, but on windows the option is within processing, in the preferences.
you can only set the maximum (Xmx). but that should be enough for most cases i suppose.

HI henri,

Thanks very much for your response. I found in the Processing preferences a box you can check for:

'Increase maximum available memory to ___ MB'

How can I figure out what is the maximum number I can put here? I tried increasing the number but still get this error when I try to export:

Exception in thread "Thread-5" java.lang.OutOfMemoryError: Java heap space

at processing.app.Base.loadBytesRaw(Base.java:2131)

at processing.app.Sketch.exportApplet(Sketch.java:1837)

at processing.app.Sketch.exportApplet(Sketch.java:1582)

at processing.app.Editor$DefaultExportHandler.run(Editor.java:1915)

at java.lang.Thread.run(Thread.java:680)

thank you

Ah, that's a different issue. The answer given by motscousus was about increasing memory for running the sketches, while you have a crash of the PDE itself. I have seen another user reporting such crash on export, which is a bit strange.
