How to increase heap size for jBoss server

Question

I have an upload files scenario in my project. When I\'m trying to upload the large files it\'s giving me an OutOfMemory error. That error is related to Java heap size.

Answer 1

In my case, for jboss 6.3 I had to change JAVA_OPTS in file jboss-eap-6.3\bin\standalone.conf.bat and set following values -Xmx8g -Xms8g -Xmn3080m for jvm to take 8gb space.
