AIB return and reason codes

When a DL/I problem occurs, IMS returns return and reason codes in an application interface block (AIB) as AIB return and reason codes.

Important:
  • The AIBERRXT of the AIB block might contain additional information about the problem.
  • X'000000F0' is a unique AIB return code assigned to the IMS Queue Control Facility manager message requeuer processor (IQCQMRQ0). It is set in the AIBRETRN field of the AIB by IQCQMRQ0 when an error is detected while performing an IMS Queue Control Facility function. For information about AIB reason codes that are associated with AIB return code X'000000F0', see the AIB reason codes information under IMS Queue Control Facility.
