Splunk DB Connect: How do I troubleshoot why Java Bridge server not running from these error messages in the jbridge.log?

Running on Windows, DB Connect 1.1.6, Java 1.8.0_31.
Here is the latest in the jbridge.log

Try to turn off SSLv3

I'm sorry, but I don't understand how to turn off SSLv3. Is that within Splunk? Java? Would that have changed sometime between Java 8 u25 and u31? As I mentioned before Splunk ran fine on Java 8 u25. Thanks!

So what I needed to do is re-enable SSLv3 in the java.security file in the Java directory. Mine was in \[SERVER_NAME]\c$\Program Files\Java\jre1.8.0_31\lib\security. Remove SSLv3 from the last line:
jdk.tls.disabledAlgorithms=SSLv3

I saved the file and it worked. Javabridge is now running.

You may also need to run notepad as Admin to change the setting in java.security, as it states another process is using the file, which is explorer.exe.

Ran into jbridge not running issue on Linux when switched to jre1.8 and this fix worked. Thanks!

Thanks for this! Had to make DBX 1.1.7 work with Splunk 7.0.1 and this was the last missing setting - thanks 🙂

BTW: another example that a lot of problems you encounter using Splunk, are actually not related to Splunk at all 😉
