Systems and methods are disclosed to support Host Initiated Processing (HIP), in which an application in a first system calls a software object in a second system that is in some respect incompatible with the first system. The calling application resides in a legacy system (e.g., an IBM mainframe), and is written based on a programming model (e.g., CICS). The called software object is based on a WINDOWS-based programming model (e.g., COM or .NET), which is incompatible with the legacy system's programming model. The HIP system converts a call from the legacy system so that the call is usable with the WINDOWS-based system, and also converts the result provided by the WINDOWS-based system into a form usable by the legacy system. Example aspects of incompatibilities between a legacy system and a WINDOWS-based system include: data representation, data types, communications protocol, passing of call parameters and return values, and error handling.

Transaction interoperability using host-initiated processing

A system that allows a user of a first domain to access a second domain. A request originates in the first domain to perform an action in the second domain. The request indicates a user of the first domain on whose behalf the request was originated. The access request is received by an adapter in the second domain. The adapter requests an access token for a user of the second domain who corresponds to the user of the first domain. A mapping table is used to identify which user in the second domain corresponds to the user in the first domain. Once the correct user of the second domain is identified, an access token for that user is returned to the adapter. The adapter then carries out the requested action by using the access token to impersonate the user of the second domain.
