SSIS 2008 R2 BIDS
I created a ADO.NET connection manager that connects to an ODBC data source. For the first time the test connection succeeds and I am able to pull the data through ADO.NET source.
When I try to edit the connection manager again or close the package and try to re-open it, the connection manager throws the below errors.
Could not create a DbProviderFactory class for provider invariant name - SSIS ADO.NET Connection manager
The connection string is not valid. Keyword not supported: 'dsn'.
I tried connecting to the same ODBC datasource through excel and it works fine not just the first time but always.
Also the issue is not just with a teradata server. I used a dsn that connects to SQL server and that works fine the first time and fails all the other times.
When i tweaked with the user profile it worked for 2 days and then suddenly stopped working.
FYI, the ODBC connection is a system DSN for which I am not the admin.
Please help!!!!
