I’m trying to create a connection to db2 but I get the following error  
 ![error%201](https://us1.discourse-cdn.com/inductiveautomation/original/2X/6/6cc46fefcf1172a785c025620713c4c913b3c8c1.png)

I tried with an as400 connection but it also fails.

Does anyone have an idea why it fails?

“Obtain a licensed copy” seems pretty clear to me. You probably need to talk to IBM sales.

I also thought that, I have a valid licence and I can connect to DB using C#.Net, also using a DSN Driver

ODBC != JDBC.

> The **JDBC** driver in use is not licensed for connectivity to QDB2 databases.

You need an additional .jar file for the DB2 JDBC driver.

According to the error message, `db2jcc_license_cisuz.jar`; which [you should be able to find somewhere in your software distribution](https://stackoverflow.com/a/48090412), apparently.
