I assume that you are trying to query the RGMA but it returns no
data? If yes, then do you have some data producers (such as Apel
on the Computing Element) that are exporting the data to your
R-GMA server? Do you have some records in your local database
(MySQL, I assume)?

I think that you're messing up the R-GMA server and the R-GMA
registry. The former is just the server that holds the data, and
the latter is the instance that glues many distributed R-GMA servers
together: it is used for the discovery of the real R-GMA server
that holds the data. For the EGEE production needs there is only
one (to my knowledge) R-GMA registry server -- lcgic01.gridpp.rl.ac.uk.
But it is running default-to-deny mode, so you should at least
register within the service to publish your data locations there.
Though I am not sure that the production LCG Registry will accept
the testbed hosts. This needs to be checked with the service
Perhaps there are some Registries for the testbed needs, or you
will need to install one (and the Schema server as well) by yourself.
