What is the DB2 Provider in connectionstring of MVC web app?

Hi, I am trying to connect DB2 database,

in connectionstring I used this format:

string connString =@"provider = IBMDADB2.1;persist security info = false;data source = sample;";

so in my case, I have something like this:

string connectionString = @"provider = IBMDADB2;Server=DBDEV:60000;Database=DBPROD001;UID=jondoe;Pwd=blahblah;";

Here, I do not know how to input the value for "provider" above, so the connection was failed.

How where can I find the provider? is it a DB2 driver I should download and import it to my asp.net MVC app?

or it is the db2 version I can query from my DB2 database and used here? thanks
