The DBH includes STXIT routines for specific error events of the STXIT event class, such as program errors or ABEND events (ABEND=Abnormal End).
Before an error event takes effect, the DBH executes an appropriate STXIT routine and tries to terminate the session normally. It then issues the STOP,KEEP admission command (see "STOP-DBH"f) internally. In the case of program errors, a dump is output first.
When an error event occurs in a session with transaction management, the DBH tries to terminate in such a way that the consistency of the data is preserved. If the DBH indicates errors by means of a job variable, an external restart may be necessary.
In a session without transaction management in which only CALL DML applications have been running, CALL DML being directly updated at the time of termination must be repaired by means of media recovery (see the “ Core manual”).
Irrespective of the backup function, the DBH sets switch 12 after the DBH session is terminated, and you receive a message.
