Dispensing with DFHTCT macros

If you are able to use RDO, with or without autoinstall, to manage all the resources formerly defined using the DFHTCT macroinstructions, you can now dispense with your DFHTCT macro source altogether. Proceed as follows:
  1. First check that the assembly confirms that all the definitions in the TCT were eligible for RDO.
  2. Check again that the CSD file now contains all the definitions needed for operation with RDO. If you are using autoinstall, make sure that the CSD file contains all necessary model TERMINAL definitions.
  3. If the CSD file now contains all the necessary definitions, code TCT=NO as a system initialization parameter. This ensures that a “dummy” TCT (DFHTCTDY) is used.

    DFHTCTDY is supplied by IBM®. It contains predefined values for the DFHTCT TYPE=INITIAL parameters. If you wish to use different DFHTCT TYPE=INITIAL parameters, you may code and assemble your own version of DFHTCTDY. Note that some of the old DFHTCT TYPE=INITIAL options are now coded as system initialization parameters. For further guidance on this, see the CICS® System Definition Guide.
