relinquishing database connections

We have a web app whose connection pooling code is modeled on basic example stuff on the web (classes like ConnectionPool, PooledConnection, etc), and my understanding is that when we restart Tomcat, all the ODBC connections will be reset on the database side. Now, we know that our particular ODBC driver has a problem which results in them not being reset sometimes, but generally it does release them.

Now, I'm wondering how the driver even knows to release them to begin with (when it's working right, I mean). Does Tomcat specifically tell the driver a special command to release all the connections or something like that?

Since the question concerns the inner workings of Tomcat, I'm moving this along to the Tomcat forum.
