Hello Fabio, I read your post at: http://zope.nipltd.com/public/lists/dev-archive.nsf/AGByKey/35A02E5C64B9 3519 about DBtab and BDBStorage. I am interested in doing the same thing. I have a Plone site that I expect to become very large and I need to find some other solutions than ZODB and its 2GB limit. Do you think you could help me with figuring this out? I have been reading documentation, posts and everything else and am a little confused. Here are a few questions I have from reading your post. 1. What did you need to install to make this work and did you do it after you already had a Plone/Zope site going? 2. What is the code that goes in DBtab.conf, I read through it about 10 times and can't understand how I need to set it up? 3. Do you have to create a new DB manually every time you want to separate info, is there no way to setup so that it dynamically adds as you need space. 4. I read a little on BerkleyDB Storage, does that give more space than ZODB? Thanks for any help on this that you can give. There should be a tutorial on this somewhere; it seems like something a lot of people would be interested in. A 2GB limit is just horrible. Thanks! Andrew R. Halko
