Splunk DB Connect: How to resolve error in dbx2.log "Exception: Invalid java path" and empty inputs.conf?

[patriziadepaola]

I have a problem after an unexpected restart of my splunk.

The Splunk DB Connect app v. 2.3.0 doesn’t work properly. This is the error in dbx2.log:

2016-12-13T02:25:18+0100 [INFO] [rpcstart.py], line 363: action=run_rpc_start rpc_start_pid=5999 args=['/opt/splunk/etc/apps/splunk_app_db_connect/bin/rpcstart.py', '--scheme']

  File "/opt/splunk/etc/apps/splunk_app_db_connect/bin/rpcstart.py", line 151, in run
    raise Exception("Invalid java path.")
Exception: Invalid java path.

I set my java_home path in

and save and restarted my RPC server.

Why, after the unexpected restart, the inputs.conf is empty with only these lines:

[rpcstart://default]
javahome = /opt/java
useSSL = 0 

Can you help me in order to prevent similar situations in future?

Are you looking at the inputs.conf in the default directory? Take a look at the inputs.conf in the /splunk/etc/apps/splunk_app_db_connect/local directory.
