Release 10.1A: OpenEdge Data Management:
DataServer for ODBC

Connection troubleshooting

Here are some reasons why a connection attempt to an ODBC data source might fail:

The schema holder is not connected.
The OpenEdge or ODBC-required environment variables are not set correctly when using the DataServer and a broker. For environment variable information, see Chapter 3, " Configuring the DataServer."
The data-source is not registered properly for ODBC client connectivity.
You have an outdated version of an ODBC DLL; for example, ODBC16.DLL, which runs on 16-bit machines only. This prevents OpenEdge from accessing the data source, though you might still be able to access the data source through your ODBC driver using another product, such as MS Query.
The data source has not been started or is not running correctly. Use the data-source utilities to check the status of the data source and the ability to connect to it.
You omitted a -Dsrv parameter that is required for the data source to which you are attempting to connect. See the "Connecting a schema holder at startup" section and the "ODBC options" section for details.
The login name and password combination that you provided during connection is invalid for the data source.
You specified an incorrect ODBC data-source name when you created the schema holder.
