Apache NiFi not able to connect to Oracle 12c using ojdbc6.jar or ojdbc8.jar

Question

We are trying to connect to an Oracle 12c database from Apache NiFi. But it simply does not work: We get the following error:

bdc2314a-669e-1e85-875c-73b035db9ba5
ExecuteSQL[id=bdc2314a-669e-1e85-875c-73b035db9ba5] Unable to execute SQL select query select * from ETSETTRA.APB where rownum < 10 due to java.sql.SQLException: Cannot create JDBC driver of class 'oracle.jdbc.driver.OracleDriver' for connect URL 'jdbc:oracle:thin@//osiXXXX:1521/UTSOFTP'. No FlowFile to route to failure: org.apache.nifi.processor.exception.ProcessException: java.sql.SQLException: Cannot create JDBC driver of class 'oracle.jdbc.driver.OracleDriver' for connect URL 'jdbc:oracle:thin@//osiXXXX:1521/UTSOFTP

The configuration is as follow,. and I have tried a lot of other combination

This should be straight forward?

Answer 1

I think the driver name is not correct:

oracle.jdbc.driver.OracleDriver

vs.

oracle.jdbc.OracleDriver

Difference between Oracle jdbc driver classes?
