Splunk DB Connect: How to resolve error "Database 'NULL' does not exist"?

Hello,

after a while my Splunk DB Connect instance stopped working and I noticed this particular error message:

ERROR ServiceResponder:352 - action=service_responder_responding_error error={}
com.microsoft.sqlserver.jdbc.SQLServerException: Database 'NULL' does not exist. Make sure that the name is entered correctly.
    at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:216)
    at com.microsoft.sqlserver.jdbc.TDSTokenHandler.onEOF(tdsparser.java:254)
../..

Basically I've checked the config and overwritten it, pure and simple. it immediately started working for few minutes then again the error message.
On the DB server side everything is OK and nothing has changed.

It's like Splunk DB Connect doesn't keep the database name.

Any idea?

I've restarted splunk and it seems to have fixed the issue...
So far if any modification is done on the input config, splunk should be restarted I suppose.

Yes, whenever you make changes to configuration files, you should restart Splunk for those changes to take effect: https://docs.splunk.com/Documentation/Splunk/6.5.1/Admin/Configurationfilechangesthatrequirerestart
