Creating Sybase-ASE data source.

[Cogknows]

Hi all,

We have a requirement to create a Datasource on Sybase-ASE DB.
The data source must be able to access all the Schemas in a particular server.
In cognos connection the database name is mandatory to crate this Sybase-ASE data source

Is  there a way to achive this with single DS?

thanks in advance..
