Transfer Lag Considerations

Generation data sets introduce a complicating factor into any non-immediate, queued procedure, as in CICS. There may be a significant time lag between the request and its implementation. For example, the partner system may not sign on for an indeterminate period of time. If a relative generation number is specified for a queued CA XCOM Data Transport transfer, and the GDG is updated before the transfer executes, the wrong file may be transferred. This would depend on whether you wanted the file designated by the relative generation number at the time of the request, or the most current generation of the file. CA XCOM Data Transport can accommodate either.
