Hi,
the script is synchronizing the data with data from another database. so there
are inserts and updates of existing data in my databaes connect by JDO.
the script doing the synchronisation is just an ant task i have written myself
(similar to the sqltask included by ant).
regards,
markus

Nick,
you are right that we don't know about the nature of the inserted data
(whether it includes updates to existing data, etc.), so some of my
remarks apply to specific scenarios only. But let's hear more about the
data inserted before coming up with any additional advice.
