Getting [ODBC Driver Manager] Data source name not found error after deployment

Question

I deployed a project in Windows Server 2008 r2 64 bit and getting following error

ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Following connection string I am using

<add name="thisconnect" connectionString="Driver={Microsoft ODBC for Oracle};Server=1.2.4/thisdb;Uid= uname;
Pwd= pname;" providerName="System.Data.Odbc"/>

Guide How I remove this error

Answer 1

Most likely means that the driver is not installed. Maybe you only have 32 bit driver?
