Oracle Exalytics Software - Version 1.0.0.3.0 and later
Information in this document applies to any platform.

Symptoms

Using Oracle Business Intelligence Enterprise Edition (OBIEE) 11.1.1.7.140715 with Teradata 13.10 data source on single node OBIEE server on Exalytics.  When connecting via OBIEE Admin tool as the biadmin user, a Teradata data source can be imported successfully.
When trying to do row counts, the OBIEE admin tool reports "connection has failed" error message.  At the same time, the nqserver.log shows message like:

[[
[nQSError: 43113] Message returned from OBIS.
]]

This problem can also occur on a standalone (non-Exalytics) OBIEE server environment.
