System-initiated end of commitment control

The system can end commitment control, or perform an implicit commit or rollback operation. Sometimes the system-initiated end of commitment control is normal. Other times, commitment control ends with an abnormal system or job end.

• Commitment control during activation group end
  The system automatically ends an activation-group-level commitment definition when an activation group ends.
• Implicit commit and rollback operations
  In some instances a commit or rollback operation is initiated by the system for a commitment definition. These types of commit and rollback operations are known as implicit commit and rollback requests.
• Commitment control during normal routing step end
  The system ends all commitment definitions for a job when a routing step is normally ended.
• Commitment control during abnormal system or job end
  This topic applies only to commitment definitions with job-scoped locks.
• Updates to the notify object
  This topic lists the uncommitted changes for purposes of the notify object.
• Commitment control recovery during initial program load after abnormal end
  When you perform an initial program load (IPL) after your system ends abnormally, the system attempts to recover all the commitment definitions that were active when the system ended.
