Multiple Derby Network Server instances on a same computer

[AirDT <co...@solgt.fr>]

Hi

1 - Is it possible to run multiple Derby Network Server instances on a same
computer? (each one with a different port and a different system derby
directory) ? 
2 - Can I do it in a single thread or should I use separate threads ? 
3 - Is there a maximum number of databases on witch  users can connect with
a given Derby Network Server ? 
4 - When there are no more connected users to a database is it possible to
automatically shutdown the database ?

Thanks in advance

AirDT

Yes, you can run multiple servers on the same machine. The system 
directory is a JVM-wide property. If you need a separate system 
directory for each server, then you can start each server in its own JVM.

I've never done this. Off the top of my head, I'd recommend a separate 
thread per server. Maybe someone with real-world experience can comment.

There is no Derby-imposed limit.

This would be an interesting enhancement request, but I am not aware of 
any way to tell Derby to do this.

Hope this helps,
