Hi Henk,

Documentation-wise, there's a bit under "starter_method" in the queue_conf 
manual page. I'm sure there's other good stuff that people can direct you 
to.

However, in my usual "suck-it-and-see" approach, if you stick an echo "$@" 
line in the starter method, you'll see how it's getting called in your job 
output files.

My 2 pence... I generally have better luck with using eval instead of exec 
- I've seen a multitude of sins being passed through to my starter_method, 
generally when qrsh gets involved (e.g. tightly-integrated parallel jobs), 
which generally get coped with better that way.
