Heap memory usage

Hi,

Recently I have made an observation that one of my application is getting deployed successfully with same heap memory in Windows 7 when I use Weblogic but it fails when I try to deploy it on Websphere!!!

Any idea why heap memory required in WAS is more than what is required in WLS???

Thanks in advance

Hi Ashutosh.

When it failed to deploy what message did it give.
Your WLS could have been using Sun JDK and in WAS you might have used ibm JDK. Hope you used the approprate Java parameters for WAS(things like GC policy etc are different).

Other thing that everyone will like to know is
a. What were the versions of WAS and WLS
b. what was the heap size

Thanks
Deepak
