The Native Execution Environment is a VTAM application that allows concurrent access to a Data Object Broker. Sessions are established by logging in through a VTAM LU2 (3270) terminal or from remote clients such as IMS TM clients running in an IMS TM Message Processing Region (MPR).
The Native Execution Environment is also optionally used to support remote peer servers for distributed data and external data servers such as TIBCO Service Gateway for Adabas, TIBCO Service Gateway for Datacom, and TIBCO Service Gateway for IMS/DB.
