I would like to connect with Oracle Database Version 11.2.0. I have installed under Help/Install new software/KNIME&Extensions KNIME connectors for common databases and restarted KNIME. But I have only drivers for my sql, SQLite etc., not for Oracle. What can I do? Thanks in advance!
Oracle does not allow bundling their JDBC drivers with other applications. Therefore it's not contained in the common database drivers. You have to install and register the Oracle driver yourself (in the preferences).
you can find information about how to register a new jdbc driver in KNIME at the Database documentation page. The documentation contains also a link to the Oracle jdbc driver.
