Start SMSDSCDS
In order to trace ACS routines in an alternate SCDS, the SMSDSCDS process must be started by DIF in addition to the SMSDEBUG product. No rules member is required in the DIF parmlib dataset. The following command can be used to start SMSDSCDS:
F DIF,START SMSDSCDS
If a change is made to the alternate ACS routine logic, then SMSDSCDS must be refreshed in order to pick up the change. This is required because the alternate ACS rou- tines are loaded into storage in the DIF address space. Thus, changes to the routines to be tested required that they be reloaded via a DIF REFRESH command. The following com- mand can be issued to DIF after changes have been made to the alternate ACS routines and the updated ACS routines have been translated.
F DIF,REFRESH SMSDSCDS
