[ZODB-Dev] DBTab questions...

[Harald Ragger]

Hello,

just played around with DBTab (1.1), Zope 2.6.1 under win and linux:

1) mounted 2 databases (see: conf 1)

db MAIN: filestorage
db BDB: berkeley db (from ZODB 3.1.1b)

a)
all ok except: when i try to cut the "Examples" from the Main Storage to =
the
BDB Folder (berkeley storage) ---> key error ( see error 1)
same operation baut "copy" instead of "cut": everything is ok, all files =
and
subfolders were copied.

b) ControlPanel--> Database Management:
Main
BDB  (as expected)

klick on BDB: ok.
klick on Main: error: (see error 2)
=20

2) tried to use berkeley as Main storage: (see conf 2)
seems to be ok, but:

it seems still to use the Filestorage Database Data.fs from my default
installation (even though NOT configured in dbtab.conf):

just copied the Examples folder three times:
Data.fs grows: Berkeley DB doesnt grow
deleted Data.fs --> Restart Zope --> all my users were gone, as did all
created content (copies of Examples folder)=20

wrong configured dbtab?
did i try things BDTab isn't thought for?

I tried under Win XP and Linux (Suse 8.1): same errors.


Regards,
Harry
