Hi, In order to connect to Oracle you would need to use the corresponding Database adapter. For example I am choosing Oracle 12c to connect to my Oracle database. The value for the Driver Class is usually automatically filled when choosing the Database Adapter. The driver class name is **oracle.jdbc.driver.OracleDriver** I would make sure that the values and connection details are filled correctly. Also note that the JDBC Driver for Oracle is already included in the Denodo Platform as seen in the section [Supported JDBC Data Sources](https://community.denodo.com/docs/html/browse/8.0/vdp/administration/appendix/supported_jdbc_data_sources/supported_jdbc_data_sources#supported-jdbc-data-sources), so it is not required to manually add the oracle JDBC driver. Hope this helps!
