Splunk DB Connect: How to resolve when RPC Service is down when initially setting up the add-on?

[dbcase]

Hi,

I'm attempting (badly) to get the Splunk DB Connect add-on working. Here is what I've done so far:

Installed the heavy forwarder on the same host as the Oracle DB
Configured it to talk to the Splunk Cloud server
Installed Java JDK 8. Also tried JRE 1.8
Configured the settings

What happens is JRE comes up but the RPC Service is down. What am I missing?

Found it!

It was this

Here is the log entry in the dbx2.log that just keeps repeating
