https://community.hpe.com/t5/operating-system-hp-ux/initial-heap-allocation-for-jvm/m-p/2818117#M720828 Dear experts,<BR /><BR />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. <BR /><BR />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.<BR /><BR />Could someone please confirm what I should be seeing in terms of behaviour of the memory? <BR /><BR />Truly appreciated.<BR />Benjamin Thu, 03 Oct 2002 08:12:09 GMT Benjamin McCartney 2002-10-03T08:12:09Z https://community.hpe.com/t5/operating-system-hp-ux/initial-heap-allocation-for-jvm/m-p/2818117#M720828 Dear experts,<BR /><BR />I have a set of Java applications running on HP-UX 11 for which I am trying to determine memory settings.
