memory arguments in start up script

[Ranjeeth Chandra]

Hi all

I was getting the exception 'java.lang.OutOfMemoryError: PermGen space'
To solve this, i added memory arguments in the start up script, which is as follows -

------------------------
set JAVA_OPTIONS= ...
set JAVA_OPTIONS= ...
set MEM_ARGS=-Xms512m -Xmx1280m
-------------------------

MEM_ARGS is the line i ve added. It is added after java options are set. But, still i am getting outOfMemoryError. I feel that the piece of code is not working as intended.

Do i need to add this somewhere else?
Also, i heard that USER_MEM_ARGS can be used to overtide memory options. I tried that too. But it didnt work.

Any help would be much appreciated

Thanks!
Ranji

The Xms and Xmx configure heap size. Heap memory is separate from PermGen space. Here is an in-depth article the subject. You can increase PermGen space with the -XX:MaxPermSize switch. 64Mb is the default.
