An optional, second, Date Control record can be defined for a User Daily to enable Enhanced Daily Checkpointing. If an interruption such as a system crash occurs during job ordering, Enhanced Daily Checkpointing facilitates automatic rerun of the job ordering process by enabling Control-M to identify the last job ordered before the interruption. Control-M can then continue the ordering process from that point.
This second Date Control record has a completely different format than the regular Date Control record. In fact, the Enhanced Daily Checkpointing Date Control record contains far more than dates.
The following table shows the format of the second Date Control record, which is required only if Enhanced Daily Checkpointing is used.
