Max heap space?

[Vishal Biyani]

What is the maximum heap space that one can set for a java process on HP-UX box? Is this governed by some system parameter/setting and can it be configured?

Hi Vishal,

As per Java on HP-UX, maximum heap size is 3.8 GB. You can set "-Xms" equal to "-Xmx"

Set "-Xmn" to be one third the value of "-Xmx".

Refer Java performance tuning guide,

Thanks for the info Arun and Ninad, only thing is the links you have given require a HP-Passport sign in , and i have a simple free login! Is it possible for you to provide some alternate pointers!

I dont think its something restricted -
Since you already have a forums id, you can create a HP Passport sign in - its free and also link the forums id to it - its in the process which will prompt you, dont worry.

Hi Vishal,

HP'S DSPP is free for HP-UX developers and partners. You can register for absolutely free. Go ahead and do it yourself.
