问题
Background: I am about to enhance an existing application. This application uses already derby.
For an other use case I want to use derby, too.
Is it possible to run embedded AND client server derby database at the same time?
回答1:
Yes, you can do this. We call this "Embedded Server", and you can find more details here: http://db.apache.org/derby/docs/10.10/adminguide/cadminov17524.html
回答2:
Not it is not possible to run the derby in both the modes at the same time. But if you run derby in the network or client/server mode then both your local and remote applications can access the databse. Remote applications means, applications running in different JVMs on the same machine or on remote machines.
