PowerExchange does not require the IMSID statement to create data maps if you import DBD information for source objects from the DBDLIB library. However, when you perform IMS bulk data movement operations, PowerExchange matches the
in the IMSID statement against the
value in the data map to determine the DBDLIB data set to use. Also, for IMS log-based CDC, PowerExchange matches the
value in the IMSID statement against the
value in the
field in the registration group.
