# Virtual Database Configuration Parameters

If you run the Distributed Action Handler in non-mirror mode, you create a `[VDBN]` section for each of the virtual databases you want to create, in which you can specify the database details.

NOTE: You cannot configure virtual databases when you set SimpleCombinatorMode to `True`.

For example:

    [VDB0]
    DbName=AllNews
    Internal=True
    Type=Combinator
    MapsTo=0:Today,2:News,3:CurrentAffairs

    [VDB1]
    DbName=Archive
    Internal=False
    Type=Distributor
    MapsTo=0:Archive,1:Library
