Defining DFHHPSVC to MVS

The DFHHPSVC module must be defined to MVS™ as a Type 6 SVC; the default HPO SVC number defined in the DFHSIT module is 215. If you want to change the default Type 6 SVC number:

  1. Define the new number to MVS. (See Defining the CICS SVCs to your MVS.)
  2. Define the new number to CICS® by using the SRBSVC system initialization parameter.

If you are not using HPO, you should not load the DFHHPSVC module into the MVS nucleus. You choose to use HPO explicitly by coding HPO=YES in the system initialization table (SIT).
