Abstract: A first computer establishes a logical connection to a second computer for requesting and/or receiving data from a database. A logical connection is independent of the underlying physical network connection used to connect to the database. A context identifier is stored by both computers to enable the context of a logical connection to be persisted between switches from one physical network connection to another within the logical connection thus enabling database transfers to be continued on a second physical network connection when a failure in a first physical network connection occurs.
