Note:
  1. Timestamp, as mentioned in Connection to DBCTL.
  2. DL/I command or call type: PCB indicates a schedule request using the DL/I call interface.
  3. PSB name (TDLRA1).
  4. Recovery token (C3C9C3E2D2D7C7F1AB6538123994CA01).
  5. The DRA is invoked for a thread request: 0301 is a PSB schedule request. (See PAPL request and return codes.)
  6. DFHDBAT must wait, because the request has entered IMS code.
  7. The DFHDBAT wait ends and DBCTL return code (00000000) is issued. The DBCTL return code is 00000000 because the PSB was successfully scheduled. See Figure 1 for an example of the DBCTL return code in the case of a PSB scheduling failure. See Return codes in DBCTL for an explanation of DBCTL return codes.
  8. 00 in the UIBFCTR, and 00 in the UIBDLTR (underscored in this example) indicate that the PSB was scheduled successfully. See PSB scheduling failure for an example of the contents of these fields, PSB scheduling fails. See Summary of DBCTL abends and return codes for information on the UIBFCTR and UIBDLTR.
