Hi Fred,

can you do:
% grep port  $SGE_ROOT/default/common/jmx/management.properties
this gives you the correct jmx port.
e.g.
com.sun.grid.jgdi.management.jmxremote.port=12345
...

To see if the jmx thread started check the following:

$SGE_ROOT/default/common/bootstrap
...
jvm_threads             1

and the qmaster jgdi* log files (especially jgdi0.log) in the directory 
specified in

grep qmaster_spool_dir $SGE_ROOT/default/common/bootstrap


And check if the correct entry for libjvm is set in the configuration:

qconf -sconf
...
libjvm_path                  /Library/Java/Home/../Libraries/libjvm.dylib
additional_jvm_args          -Xmx256m

check if the libjvm_path is really existing


If all this is working you should try
telnet <yourhost> <jmx port from the grep above>

telnet myhost 123
Trying nnn.nnn.nnn.nnn...
Connected to myhost.
Escape character is '^]'.

^]
telnet> close
Connection closed.



[ Try this only if the other tests above succeed]

Another possible problem why nothing is shown could be a version 
mismatch of the jgdi.jar and juti.jar files:

cp $SGE_ROOT/sgeinspect/sgeinspect/modules/ext/jgdi.jar 
$SGE_ROOT/sgeinspect/sgeinspect/modules/ext/jgdi.jar.saved
cp $SGE_ROOT/sgeinspect/sgeinspect/modules/ext/juti.jar 
$SGE_ROOT/sgeinspect/sgeinspect/modules/ext/juti.jar.saved

cp $SGE_ROOT/lib/jgdi.jar 
$SGE_ROOT/sgeinspect/sgeinspect/modules/ext/jgdi.jar
cp $SGE_ROOT/lib/juti.jar 
$SGE_ROOT/sgeinspect/sgeinspect/modules/ext/juti.jar
