[Zope] Zope product instance startup

Hello all, I have created a python product that creates a CORBA connection and makes a lot of things with it. Each instance of this product has its own connection string (like the zope database adapters), and I don't know the way to execute the connection routine to open the connection after Zope has started up. Is there any method (like manage_afterDelete or manage_afterClone) that I can use to open and close the connection of the object instances?
