When you have high availability, the SQL transformation provides database connection resiliency for static and dynamic connections. When the Integration Service fails to connect to the database, it retries the connection. You can configure the connection retry period for a connection. When the Integration Service cannot connect to the database in the time period that you configure, it generates a row error for a dynamic connection or fails the session for a static connection.
The SQL transformation database connection is not resilient for Informix or ODBC connections.
