For IMS data sources, the REG_COPY CHECKXREF statement forces the DTLURDMO utility to load the corresponding data map on the target system and to update the registrations with the database organization information from the DBD that is specified in the data map when copying registrations. Use the CHECKKXREF parameter if you change the DBD to specify a different database organization and then need to the change the registrations.
This statement has no parameters.
When you run the DTLURDMO utility with a REG_COPY CHECKXREF statement in the SYSIN and a TARGET value of LOCAL, ensure that the IMS RESLIB data set, or whichever library contains module DFSVC000 in your installation, is specified in the STEPLIB concatenation in the DTLURDMO JCL. If the TARGET value specifies a PowerExchange Listener node, ensure that the IMS RESLIB data set, or whichever library contains module DFSVC000, is specified in the STEPLIB concatenation in the target Listener JCL.
