You can't.  However, you could create a new kind of connection
object that did this for you.  This should be a reasonably 
straightforward hack of ZOracleDA:

  - Take a database name through the web.

  - Maintain an internal pool of actual connections, one per user.
    If this becomes expensive, then provide some logic for
    limiting the pool size by retiring unused conections or by
    only keeping connections for some function of a user hash.
