RADIUS Cannot Re-Establish a Connection to ODBC Data Source
Article ID: 221196 - View products that this article applies to.
This article was previously published under Q221196
When Remote Authentication Dial-In User Service (RADIUS) uses an ODBC data source for validation data, it cannot re-establish a connection to the ODBC data source if the connection is broken (database crash, database maintenance, network storm, hardware problems, electrical outages).
No retry logic was implemented for ODBC, so the service fails to start if the database is unavailable, and fails to reconnect if the server is unreachable for any reason.
