Biztalk SEHException Source: IBM.Data.DB2.iSeries when connecting IBM DB2

Hi,
In my biztalk application I used Helper.cs class and I have to connect to DB2  in this class. Connection code in the below:
 AS400SP as400Sp = new AS400SP();               iDB2Connection conn = as400Sp.GetConnection(“DB2Connection”);
When I deploy to biztalk application on my local admin it works fine. But when I  create msi. package and deploy to test machine I get the XLANG error below.

Exception type: SEHException
