Increasing memory in Eclipse

Dear list,

I hope this is not too off-topic, but I am developing ImageJ plugins using
Eclipse, and I really like it except I keep running up against what appears
to be an absolute memory limit of 63MB. You can¹t set the memory in an
Eclipse instance of ImageJ by Edit>Options>Memory... Because it generates an
error ³ImageJ is unable to change the memory limit.² However the Current
limit it gives is 144MB well beyond the 63MB Out of Memory Eclipse error.
I tried changing the eclipse.ini file from the default:

-Xms40m
-Xmx256m

to

-Xms256m
-Xmx512m

but I still get the Out of Memory All available memory (63MB) has been
used. I have been struggling with this for a long time but can¹t seem to
find any help in the Eclipse Help or Help lists they seem reluctant to
deal with ImageJ issues for some reason. I am using a Mac G5 dual 2.3GHz
with 2GB ram. If anyone knows how to increase the memory in Eclipse, I
would be very grateful. Thanks in advance.

Re: Increasing memory in Eclipse

Hi,

I'm no expert on Eclipse, but I recall having the same problem. I solved
it by editing the run configuration and adding '-Xmx256m' to the program
arguments.

Hope this helps
Jon

Hello Christopher,
to increase the memory of your eclipse environment start it with a link
like:

C:\Programme\eclipse\eclipse.exe -vmargs -Xms256m -Xmx512m

To increase the memory of imagej when you start it from eclipse:

right click the ImageJ class and choose the menu entry run>run... to
open the configuration dialog
In the Arguments tab use the VM arguments to set the memory:
-Xms256m -Xmx512m

Hope this helps,
Volker

Yes, Thank you Volker! This problem has been plaguing me for months and,
given eternity, I probably would have figured it out myself, but it was not
obvious.

I had a similar problem because on imageJ program start up, I blocked
the changes that I tried to put into effect. I don't know if that
was your problem - I am only starting myself.
