Hi there: In the ZODB Howto: "A Storage Manager is the database back end of Zope. The default storage manager for Zope is a ZODB3 database file object that can be found in the top level var directory of Zope (var/Data.fs). There are other storage managers for Zope, in various stages of development: o The Relational Storage Manager stores all Zope transactions in a relational database. This is still experimental." I've looked all over but I was unable to find the way to change the storage manager from the Data.fs file to a relational DB (mySQL, Sybase, etc ) or indeed to any other kind (like the Temp storage manager also mentioned in the ZODB Howto). Can anyone give me some insights or pointers on how to do this ? C U! -- Mario Valente
