Connection Reset with db-connect and MS SQL

bleinfelder — Fri, 16 May 2014 08:10:47 GMT

Hi there,

I struggled quite a time to make db-connect work with my splunk 6.0.3 installation.

Error Message in dbx.log is attached.

I solved the issue with replacing JRE8 with JRE7. I guess there is some issue with different encryption ciphers used in JRE7/8.

As I couldn't find anything on this issue maybe this note is helpful to others.

Regards,

Bernd

Thanks for the note. The jtds issue is in the process of being fixed (http://sourceforge.net/p/jtds/bugs/725/) and we'll pick it up as soon as practical.
