ABSTRACT:
Methods, systems and computer program products are provided for error recovery in a network having a first application associated with a first endpoint node and a second application associated with a second endpoint node. These methods, systems and computer program products non-disruptively switch the first application associated with the first endpoint node to a third endpoint node arbitrarily selected from existing endpoint nodes when the first endpoint node is no longer available to the second application associated with the second endpoint node. The first application is provided on the third endpoint node in substantially the same state as the first application existed on the first endpoint node prior to the unavailability of the first endpoint node. The present invention is preferably carried out where the endpoint nodes are VTAM facilities. Also, the first and third endpoint nodes are VTAM facilities in the same SYSPLEX.
