DBX MSSQL Cannot Connect

chrisboy68 — Thu, 29 Jan 2015 16:07:28 GMT

Hi,

I have been struggling trying to get DBX connected to an MSSQL DB. There is no named instance:

In database.conf,
database = SERVERNAME/DB

If I use the host name for the default instance name, I get:
Error while executing command: Error getting database connection: Server SERVERNAME has no instance named SERVERNAM.

So this tells me a connection is trying to be made to the DB. So, then I change the conf, just to list the DB.
IE:
database = DB

When I do this, it just hangs and timesout.

Anyone know the correct syntax to connect to a MS DB w/out a Named Instance? I have an ODBC Data Source working fine on this DB, so I know my credentials are fine and the Server Name.

Thank you!

Chris

Hi, been struggling to get DBX to connect to an MSSQL DB. I did install a JDBC tool directly on the splunk server just to verify my credentials or JDBC was an issue, all worked out fine.

I have debug running, here is a portion of the DBX Log:

2015-02-17 12:29:55.780 dbx4915:DEBUG:Database - Connecting to database database

Here is a portion of the jbridge_cleint.log:

It appears that its not even hitting the DB and the javabridge is refusing the connection. I played with the JDBC connections and nothing made a difference.

Javabridge is up and running, below is from the status page.

Bump

Any ideas? Nothing is working with this client. As I stated other JDBC clients work fine.

Thank you,

Chris

One of the line in the message log reads "Connection refused.". Check:
1. MSSQL is set to use SQL Authentication.
2. JAVA_HOME is auto-detected by the app while setting it up after installation.
3. If using DBX 1.1.7, use jre7u or jre8u45 for DBX 2.0.x

Pls share what OS/SQLver/JREv are you have in your setup.

Mitesh.
