jdbc_response probe fails to connect to Oracle 12c database

Cannot monitor Oracle 12c databases with the jdbc_response probe.  The loglevel 5 logs captured from the probe generate an error message similar to the following when the probe is activated, or when testing the connection to the database:

Could not connect to jdbc:oracle:thin:@<server>:<port>:<database>. No matching authentication protocol.



Oracle improved authentication security with the 12c release which prevents older oracle jdbc drivers from successfully authenticating when logging into the database server.


jdbc_response probe through the current GA release version 1.23


  1. Deactivate the jdbc_response probe.
  2. Download a copy of the ojdbc7.jar jdbc driver jar file for the Oracle 12c database from Oracle.
  3. Rename the downloaded jar file to oracle.jar
  4. Replace the <installPath>\Nimsoft\probes\database\jdbc_response\lib\oracle.jar file on the robot where you have the jdbc_response probe installed with the renamed jar file that you downloaded.
  5. Activate the jdbc_response probe.
