How to configure Splunk DB Connect 3.3 to connect to Oracle OCI DB?


Trying to connect to Oracle 18c db, I have followed the instructions in the troubleshooting guide "Connect Splunk DB Connect to Oracle Wallet environments using ojdbc8" without any luck.

I'm getting the following error "[dw-58 - POST /api/connections/status] ERROR io.dropwizard.jersey.errors.LoggingExceptionMapper - Error handling a request: 2a01705792fdb22a java.lang.NullPointerException: null
at com.splunk.dbx.connector.logger.AuditLogger.replace(
at com.splunk.dbx.connector.logger.AuditLogger.error(" regardless of what I put in the connection string which leads me to believe that the message is just disguising the real issue. I have the logs set to "DEBUG" but no information other than the null pointer exception mentioned above. I am able to connect to the DB from the server using sqlplus and show the connection string using tnsping.


Even i am facing the same issue when i am trying to establish a connection between MSSQL database and splunk HF.

can anyone help

jdbcDriverClass = io.lenses.jdbc4.LensesDriver
jdbcUrlFormat = jdbc:lsql:kafka:http://<host>:<port>
testQuery = SELECT amount FROM cc_payments LIMIT 1
