Hello,

I bought the Oracle Data Provider from Acuiti yesterday and am trying to install DNN 4.9 to use an Oracle DB. I have created a blank user and also modified the two instances in the OracleWeb.config file to reflect the user credentials and machine name on which the database is installed. I have also renamed the OracleWeb.config to web.config. When I try to browse to the Default.aspx file from IIS I get the following error. Any help would be highly appreciated.

Thanks,

Rajesh

Sanjay,

Thnks for your reply. Is it better then that I install dnn 4.8 and use the Oracle DP or can you please suggest fix for the IIS settings.

Thanks,

Rajesh

I have the same problem, but i'm working with MSSQL 2005, this is my first time trying to instal dnn so maybe something with web.config or database users could be also wrong
