java.lang.​OutOfMemor​yError について

MATLAB R2016b (9.1.0.441655) 64-bit (glnxa64) is used to predict survey information.

About three days ago, the following error occurred, and it examined in various ways and it understood to the place where Java heap area was short.

ExceptionObject: [1×1 java.lang.OutOfMemoryError] identifier: 'MATLAB:Java:GenericException' message: 'Java exception occurred: ...' cause: {} stack: [3×1 struct]

I checked the setting method on the MATLAB side, but I understood how to set it from the management screen by GUI, but because of AWS the GUI can not be used and I do not know how to set it.

It is saved if someone can tell me how to set it from the command line.

In addition, I think whether the memory use situation of AWS has no problem. KiB Mem: 60614968 total, 56340112 free, 1448516 used

Thank you.

You can change Java heap size by editing $prefdir/matlab.prf file.

By default in Linux MATLAB R2016b, $prefdir is would be /home/USER/.matlab/R2016b. If you want to increase Java heap size to 4,000MB, try the following.

vi /home/USER/.matlab/R2016b/matlab.prf

and add ( or change if JavaMemHeapMax is already existing)

 JavaMemHeapMax=I4000

Then restart MATLAB, the Java heap size will be changed.

Thank you very much. I will check it.
