Issue/Introduction

When trying to connect to the repository, I am receiving the following error:

FATAL CA Test Data Manager- Datamaker logon error.
Cannot connect using the supplied values.
ORA-12154: TNS could not resolve the connect identifier specified. 

Cause

This error message can occur when installing Datamaker or connecting to the repository in Datamaker, Portal, or TDoD. The most common cause of this error message is that the tnsnames.ora file in not in the correct location for TDM to use it. Also make sure that the version of Datamaker installed on the system is compatible with the repository version.

Environment

CA Test Data Manager (TDM)- Datamaker, Portal, or Test Data on Demand (TDoD)

Resolution

To resolve this issue, please copy your tnsnames.ora file from <ORACLE_HOME>\Network\Admin into the following locations:

  • C:\Program Files (x86)\Grid-Tools\GTDatamaker
  • C:\Grid-Tools\TDoD\TDoD_ConfigEditor\libraries


You may also need to check your rep.xml file has the same updated information as the tnsnames.ora file. This document outlines how to find existing rep.xml files and create a new one if needed: https://support.ca.com/us/knowledge-base-articles.TEC1656693.html
