Apache NiFi无法使用ojdbc6.jar或ojdbc8.jar连接到Oracle 12c

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?
