Re: [Wrapper-user] Problem with JVM parameters incase of JDK 5

[Ashish A. <ash...@ya...>]

Hi Leif and All,

I am able to resolve my problem. The problem was that when I run JBoss using run.bat file, all JVM parameters (especially realated with Heap size) are passed properly to JVM and the memory goes above 500 MBs for one of the operation in my application, which is well expected. I observed this using jconsole utility. But when I run JBoss using wrapper, the memory hangs around 190 MB and hence the same operation took more time in this case.

I am able to resolve this problem by supplying additional JVM parameter i.e. -server.

Thanks Leif and everyone for your help.

regards,

Ashish

Ashish,
What is the full command line that is being generated by the Wrapper?
It should be in the wrapper.log file.

Cheers,
Leif
