From each Archer Server (including web and job engine servers)
1. Start ->ODBC Data Sources ->  Verify there is a valid DSN connection to the Oracle database that is referenced from the ODBC connection string configured in the Archer Data Feed.

2. Confirm that each Archer server has a tnsnames.ora file correctly configured with a valid reference to the database server and database name that is being used by the Archer Data Feed.  From a Windows Command prompt run the command:

notepad.exe %ORACLE_HOME%\network\admin\tnsnames.ora

3. If missing, install and configure Oracle ODBC software on all Archer servers (including web and job engine servers).  The software needs to be configured to point to a valid Oracle Database server that is reachable from all Archer servers in the environment, and it also needs to be configured with a reference to a valid Database on that server.
