Abstract
Abstract The invention provides a mechanism to integrate differing transaction protocols by augmenting an existing Resource Manager to act as both a Transaction Manager and a Resource Manager within a system which also contains a standards-based Transaction Manager which has overall transaction management responsibility. The Transaction Manager within the Resource Manager acts as an interface to provide specific mappings between the Transaction Manager which has overall transaction management responsibility and a proprietary transaction processing system which it manages. The interface is required to map different transaction identification specifications, record appropriate state information and have procedures to effect failure and restart scenarios.
