[Zope-DB] DCOracleStorage error

[Alessandro Pinato]

Hello,
I want to use DCOracle2 - DCOracleStorage to as a ZEO Storage Server.
The Zeo server go up well, but Zope client return this error during startup:

AttributeError: DCOracleStorage instance has no attribute 
'supportsTransactionalUndo' 

My StorageConfig.py

import DCOracle2, DCOracleStorage
zope=DCOracleStorage.Full(
        lambda : DCOracle2.Connect('zope/zope@mydb'),
        prefix='zodb_',
        )

My custom_zodb.py

addr=('10.26.49.26',8000)                                                                                                         
import ZEO.ClientStorage
Storage=ZEO.ClientStorage.ClientStorage(addr, storage='zope')
                                                                                                                
Help me please.

Bye

Alessandro
