To connect the IBM DB2 through JDBC from Virtual DataPort, I would perform the following steps,
1. Download the JDBC driver of IBM DB2, from the vendor’s website.
1. After downloading the driver, copy the jar file and paste in the DB2 11 folder located at <DENODO-HOME>lib-external/jdbc.
1. Start the Virtual DataPort Server and click on New> Data source > JDBC and Choose the Database Adapter as the DB2 11.
1. Then, enter the necessary detail such as Driver classpath, Driver Class, Database URI, login credentials and etc, and click on save.
For more information regarding the JDBC connection, have a look at [JDBC Sources](https://community.denodo.com/docs/html/browse/latest/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources) section in the Virtual DataPort Administration Guide.
Hope this helps!
