Sun J2SE 1.4.2 max heap size

[J Casqueiro]

Hi there !

Can anyone confirm what is the max heap size for the VM in Sun's J2SE
1.4.2 SDK (for windows 64b Itanium 2) ?

In the documentation it is mentioned that for Solaris we have a 64b
address space but I couldn't find anything regarding wintel 64b and I
would like to confirm.

Thanks/Brgds

If you are speaking about the plugin, I believe it is 96 (on Wintel), but
you can up to it with the -Xmx option. For example, under Wintel, to up it
to 256:
control-panel
java 2 plugin
addvanced tab
and under "java runtime parameters:"
-Xmx256m

IA64 64-bit for Windows and Linux
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
With the release of J2SE platform version 1.4.2 comes a new addition to the
platforms supported by the HotSpot JVM. Full 64-bit support for the Intel
IA-64 architecture and the Itanium family of processors is a major addition
for the J2SE platform, and is a strong example of Sun's continued focus on
enterprise and network computing.

With a new port to IA-64 comes the opportunity to leverage past work with
the 64-bit version of the Java virtual machine for the SolarisTM Operating
System (SPARC® Platform Edition) ensuring delivery of a reliable, scalable,
high performing, and highly competitive 64-bit version of the JVM machine.

This gives 64 bit addressing. The size of an address is in
transparent in Java. We have always had 64 bit data
