Actually, you can make multiple connections to the same database as long as
all the connections are coming from the same client (the one that is
embedded with *that* server instance). You just can't make multiple
connections from divers clients, e.g. an app connecting via fbclient.dll on
the same machine, an app connected to an embedded database in a different
application directory, or any remote clients.

So (provided TIBDatabase is session-safe, i.e. can be isolated from every
last artifact of all other connections) you can create as many instances of
it as you need, subject of course to machine resource limits.
