PowerExchange can read bulk data from a CA Datacom source on an MVS system. However, PowerExchange cannot write bulk data to a Datacom target.

PowerExchange treats Datacom as a nonrelational DBMS. Consequently, you must create a data map for a Datacom data source from the PowerExchange Navigator. PowerExchange uses the data map to access Datacom source data and metadata to create a relational view of the source records for processing.

Because a Datacom database is on an MVS system, it is remote from the Windows system or systems on which the PowerExchange Navigator, PowerCenter Client, and Power Integration Service run. Therefore, you must run an additional PowerExchange Listener on the remote MVS system and verify that PowerExchange and PowerCenter can communicate with it.
