Re: [Wrapper-user] AggressiveHeap

[Thierry H. <th...@in...>]

Are you on windows or solaris/linux ?.

If you are on windows the problem come probably from some dll loaded
somewhere ( up to the system) in the address space.

Aggressive Heap try to allocate the max memory possible or at least to
map the addresses requested to use this memory. The system will refuse
to map the range of address because the range could not be reserved (
range + address of dll > max address space allowed per process ).

There is not so much to do here.

First try to lauch your appli without the wrapper.

Then try to launch the wrapper without the dll ( it's normally working
the dll is use full to handle signal ) .

Then there is some method to force the address where the dll is loaded
but I don't remember them.

The best way is too not use Aggressive heap ( which is not recommended
by sun ;) ) and to specify a max memory in which everything fit in.

I am trying to get the java option aggressive heap to work. I have put
the following lines in the wrapper.conf:

=20

# Java Additional Parameters

wrapper.java.additional.1=3D-server

wrapper.java.additional.2=3D-XX:+UseParallelGC

wrapper.java.additional.3=3D-XX:+AggressiveHeap

=20

# Initial Java Heap Size (in MB)

#wrapper.java.initmemory=3D3

=20

# Maximum Java Heap Size (in MB)

#wrapper.java.maxmemory=3D256

=20

The following appears in the log:

=20

STATUS | wrapper  | 2006/09/28 10:44:55 | --> Wrapper Started as Service

STATUS | wrapper  | 2006/09/28 10:44:55 | Launching a JVM...

ERROR  | wrapper  | 2006/09/28 10:45:00 | JVM exited while loading the
application.

initialization of VM

INFO   | jvm 1    | 2006/09/28 10:45:00 | Could not reserve enough space
for object heap

=20

The application will start okay without the wrapper, but fails with the
wrapper, at start up it will use no more than 20M.

I have tried it with 3.1.2 and 3.2.1 version.

Any Ideas?
