Re: Max Heap Size.
Hi Ben, Thanks for your kindly reply. I have application it takes more more then 900MB .becoz my application stores the data into the memory as long as server is running. could you please give some more detail to find how much memory it occupies where i can the bottleneck between web server and app server. Sorry for troubling you again. i have big problem on this issue. Thanks Kannan.

JRun has some really nice metrics built in to log memory growth. I would recommend setting Xms and Xms both equal to some number like 128 meg so that memory is 'pre-allocated', and turn on the collection of memory statistics. Then you can see if you don't have a leak. What the amount of memory used. If you do have a leak you can get a tool like OptimizeIt (trial available) to help pinpoint it. I've tried using a free tool called jmp, but it had some reliability problems last time I tried about 6m ago. Good luck, BenG.

Max Heap Size.
Hello, I have some problem on the my application. i will give my scenario of my problem. when i start both app server @ web server it works fast . when people starting using the web. slowly it become very slow. and after some time it is not working ( i mean somebody try to open a page it never shows up). I think i have problem on the memory or between app server and webserver( connector). Please i need help on this issue. Anyone response my mail it very very thankful. How to increase the Max Heap Size & VM Arguments : right now my Max heap size is : 512 MB & VM Arguments : -Xmx1024M. i want increase both heap size and VM Arguments. please i need example value. please recommends on this too.
