Java Heap Memory Allocation
Hi there!
I'm trying to increase Java Heap size for Java WS applications. I have entered the below in the deployment properties:
deployment.javapi.jre.1.5.0_03.args=-DcheckMemory\=false -Xms32m 朮mx256m -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 -XX:NewRatio=2 -Dsun.java2d.ddoffscreen=false
As a result I have been getting the following messsage: "Several Java Virtual Machines running in the same process caused an error" or, whilst trying different combinations: "Java Plug-in Fatal Error - The Java Runtime Environment cannot be loaded".
Once I get the first error I am forced to log-out otherwise any Java Apps started will get the error, can't see any processes to kill in the Task Manager either.
Any help would be muchly appreciated!!
Many thanks,

Sure. What I do not understand is why you
do not use the technique shown here..
http://www.physci.org/jws/#giffer
(The example, besides using a library, offers
either 'standard memory' or 'expanded memory'*
versions of the launch file.)
* that requests a maximum of 512 Meg.

Try these:
/* Data Virtue BASE */
"-J-Xms32m -J-XX:PermSize=32m -J-XX:MaxPermSize=96m -J-Xverify:none -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled -J-XX:CompileThreshold=100"
/* Data Virtue HIPO */
"-J-Xms32m -J-Xmx128m -J-XX:PermSize=32m -J-XX:MaxPermSize=96m -J-Xverify:none -J-XX:+UseConcMarkSweepGC -J-XX:+CMSClassUnloadingEnabled -J-XX:+CMSPermGenSweepingEnabled -J-XX:CompileThreshold=100"
