In 2.6, with DBTab, I had something like: [Storage: Packed] type=ClientStorage addr=zeo://localhost:6001 storage=packed cache_size=100000000 [Database: Packed] cache_size=4000 mount_paths=/somepath open_at_startup=1 The closest I can get in 2.7 is: <zodb_db packed> <zeoclient> server 127.0.0.1:6001 storage packed cache-size 100000000 wait on </zeoclient> mount-point /content cache-size 4000 </zodb_db> What do I use instead of open_at_startup or has this functionality vanished in 2.7? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
