Description

DFHTDA, which is link-edited with RMODE(ANY), handles DFHTD macro requests. In particular:
  • DFHTD TYPE=GET|PUT|PURGE requests are converted to the corresponding DFHTD CTYPE=GET|PUT|PURGE requests.
  • DFHTD CTYPE=GET|PUT|PURGE requests for intrapartition queues are routed to DFHTDQ for further processing.
  • All of the processing for DFHTD CTYPE=GET|PUT for extrapartition queues is done under the QR TCB.
  • Much of the processing for DFHTD CTYPE=OPEN|CLOSE for extrapartition queues is done under the RO TCB.

CICS® Transaction Server for z/OS® uses QSAM GL|PL mode processing.
