I am working on a project to convert several old informix standard
engine databases over to a new platform. I converted a small database
and have been doing some testing and so far Firebird (super server)
seems to be working wonderfully.

Does anyone on this forum have any experience using Firebird in a large
production environment? I know that large is relative.... some of the
system that I need to convert have as many as 50 concurrent users and
several tables with 5 million+ records. The databases grow to 10 or so
gigs. So when I say large I mean to large for ms access not oracle :-)

We will be using Tomcat and JDBC to access the database.

Thanks,
Fred.
