[Opendap-tech] Hyrax vs Thredds: large dataset support (Java)

Try googling for this:
" An Exploration of Candidate Architectures for IOOS Data Sharing "









I've problems to serve a 10GB~ .nc file using hyrax!

THREDDS works for all other nc, hdf5 and (my handler) sql type of file but won't show my wrf_20081127.nc file wich should be a regular nc file (nc dumps this file with no problem).
LFS should be automatically included in the netCDF-4 server or not?
Here are commands I use to get my modules installed (version latest-stable):
NETCDF:
$cd netcdf-4.0

$./configure --prefix=/home/cancellieri/platform/stable/netcdf-4/ --with-hdf5=/home/cancellieri/platform/stable/hdf5/ --with-szlib=/home/cancellieri/platform/stable/szlib [--enable-cxx-4 (works but unuseful)] [ --enable-netcdf-4 --enable-benchmarks (handler won't work if)]

$make -j 8 && make install



$cd netcdf_handler

$./configure --prefix=/home/cancellieri/platform/stable/bes/ --with-netcdf=/home/cancellieri/platform/stable/netcdf-4/ [ --enable-debug=[1,2]  You have to FIX=NCArray.cc:85 commenting out a variable]

$make -j 8 && make install

Using bescmdln to request this file:

BESClient> set container in catalog values c,/nc/wrf_20081127.nc;

<?xml version="1.0" encoding="UTF-8"?>

<setContainer>

    <response>

        <BESError>

            <Type>4</Type>

            <Message>Unable to access node /nc/wrf_20081127.nc: Value too large for defined data type</Message>

            <Administrator>admin.email.address at your.domain.name</Administrator>

        </BESError>

    </response>

</setContainer>

BESClient>exit


Where i've to look for to solve this "Value too large" error???
