Java applications reserves 240 MB memory on 11i

Ingo Huckele_1 — Wed, 01 Mar 2006 05:55:50 GMT

Hello,
we have different java applications and with HPUX 11i java reserves about 250 MB memory. Is the displayed value from "top" correct?
Is there any kernel parameter or patch to reduce this?
With HPUX 11.00 it was only 8 MB.

Thanks in advance

Hello Ingo,

You need to look into http://www.hp.com/products1/unix/java/?jumpid=go/java
http://h18012.www1.hp.com/java/patches/index.html

for more information according to your Java version.

top may be 'mis-reporting' the size.

Also have a look at:

Hi Ingo,

You need to look at the actual java command being issued - specifically any -Xm????? statements on the command line.
They designate the memory allocation for the command. Use the following to see the entire command line:

ps -efxp

HTH,
