Maximum heap size for 64bit JVM

843829Jun 20 2008 — edited Jun 24 2008
Hi,

I am trying to set the maximum heap size for a java process in a 64bit JVM . I am not able to set more then 3G

command line config:
java -Xms64m -Xmx3g -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=8000 com.superpages.puboptions.CampaignFeedStarter >> publisher.out 2>&1 &



Hardware / software configs
*$uname -a*
SunOS labsbear 5.9 Generic_122300-19 sun4u sparc SUNW,Sun-Fire-V440
*16GB total physical memory*
*4 processor machine*

*64 bit JVM*
JDK1.6

where is this limitation coming from. How to set the heap size to 6g.

Thanks for your time

Meena
