Transaction abend processing

If, during transaction abend processing, another abend occurs and CICS® continues, there is a risk of a transaction abend loop and further processing of a resource that has lost integrity, because of uncompleted recovery.

If CICS detects that this is the case, the CICS system abends with message DFHPC0402, DFHPC0405, DFHPC0408, or DFHPC0409.

The action taken by CICS on the abend exit code can:
  • Terminate the task normally
  • Terminate the task abnormally

Abnormal termination of a task describes the processing that might follow the abnormal termination of a task.
