Thanks peter,

The javac is indeed linked to .java_wrapper, but to me it's not clear what I
should change such that it works in classic mode. Neither do I find anything
about that in the man pages. Doesn't anyone knows how to execute
java -classic .. on a Linux box ??

yep.

java -classic -jar orion.jar

works fine for me. I'm using sun's java version 1.3.1.

I am currently sitting on a w2k box, but I remember that under Unix many

of

these files are links to a wrapper for either hotspot or classic JVM. You
may have to play around and change those.

Thanks peter,

I tried it as classic, but it doesn't work. It complains that it can't

find

the JIT, wheras it is able find it, as the below, any idea why this is (I
haven't got much experience with running the jvm in different modes, any
idea where to find more info, as I can't find it in the man java ??) ??:
-------
[orion@ojo Orion]# java -classic orion.jar

I have seen other instances where profiling doesn't work with the

HotSpot

JVM - use the Classic, and it (may) work.

Thanks Marcel,

Indeed I get more information when I start with -Xprof, however when I

use

the -Xrunhprof I get the following error (the total command is also
included):

Funny !!!,

Hi Eddie,

You could try to use the JVM profiler (startup arguments -Xprof
and -Xrunhprof). This is ofcourse not orion specific, but you can give

it

a

try. You can also try leaving out parts of your application until you

find

the bit that's causing your problem.

Marcel

Can someone please tell me how to monitor the cpu usage of

Orion in detail

per component/item/application ?

When I use orionconsole I can only view the overall memory

usage of all

application, but that's it. With "top" I see it is using a

lot of cpu
time:

about 50 percent.
But I want more information, how do I get that ??

Eddie
