[Zope] manage_minimize

Hi, Zope-2-7-6 I would like to minimize cache of my ZODB mounted database by manage_minimize function from PythonScript placed in Root Folder. I created the mounted database called "mounted_database" in ZODB. When I do it this way context.Control_Panel.Database.mounted_database.manage_minimize() it minimizes main database but not mounted_database, but when I do it this way context.REQUEST.RESPONSE.redirect('Control_Panel/Database/mounted_database/manage_minimize') it works. Why??? I have to use the first solution becouse I'm going to place more code after minimizing. Regards Krzychu
