Re: [fully-OT] File replication between webapps
Oracle is the only aproved database (clusterable or not). This is the reason I was looking for a "rsync"-linke solution.

One of them is that the (only) usable database is Oracle. As we don't use a database for the app, adding orcale only to get DB replication may be difficult to explain (and will add a significant cost) Sure it does :) If oracle is only 'clustered' database possible but other non lcustered ones are available, maybe C-JDBC could help you (it provide RAID like ontop of any database).
