The DFHDCT macros are supported for migration purposes only. All DCTs must be migrated to CSD resource definitions using the DFHCSDUP MIGRATE facility.
The DFHDCT TYPE=(INITIAL,MIGRATE) and DFHDCT TYPE=GROUP macros, and extensions to the DFHCSDUP MIGRATE command help you convert your existing DCT macro definitions to RDO definitions. See RDO GROUP for migration—DFHDCT TYPE=GROUP for more information.
The destination control table (DCT) contains an entry for each transient data destination. A destination can be intrapartition, extrapartition, indirect, or remote. You code different DFHDCT macros for each type. The macros specify the symbolic name for each destination, and other information that CICS® needs.
The DFHDCT TYPE=GROUP macro can be used for migrating DCTs to the CSD file. A TYPE=(INITIAL,MIGRATE) macro must be specified in this case, to obtain the correct AMODE and RMODE.
