DFHKCD

DFHKCD is the dispatcher part of task control module DFHKCP for CICS version 2.1. It performs the following functions:

  • checks for the expiration of any time-ordered event and calls internal control to initiate the event.

  • frees some storage areas if CICS is short on storage.

  • scans the chain of active tasks to locate and dispatch an eligible task.

  • interfaces with operating system timer facilities.
