Hi Rohan,

Is oracle installed on this server?  Try to connect to database in server, instead using the Connection string from Development machine.

Or better use ODBC instead of OLEDB.

Regards,

Jagan.

Everything installed properly. ODBC we have already implemented but the thing with ODBC is it is very slow compared to OLEDB

Hi,

Try to create a qlikview file in server and connect to database using OLE DB in server.
