Initial Heap Allocation for JVM

[Benjamin McCartney]

Dear experts,

I have a set of Java applications running on HP-UX 11 for which I am trying to determine memory settings. I have specified the initial memory size to 256MB using -Xms256m and the maximum size to 512MB using -Xms512m.

I expected to see the resident memory size (RSS) indicate 256MB as soon as the application started however it sits at 118MB only. I have had problems with the application running out of memory so I am concerned that it is not being allocated the appropriate memory upon startup and that it cannot grow.

Could someone please confirm what I should be seeing in terms of behaviour of the memory?

Truly appreciated.
Benjamin

If you are running out of memory, maybe we should look at your system config and kernel parameters?
