How does CA XCOM Data Transport for z/OS manage Generation Data Sets (GDGs)?
If you submit a type=schedule transfer with GDG(0) or GDG(+0) specified for the LFILE, the CA XCOM Data Transport server resolves the filename to be the current GxxxxV00 number at the time the transfer is scheduled. When local file is specified with LFILE=, XCOM transfers according to its relative generation number. This permits maximum flexibility without alteration of the production JCL. Using LCLDS01 to specify the GDG to be transferred is not recommended.TYPE=EXECUTE Transfers
Since the transfer is immediate, the filename is resolved immediately.Transferring all Generations
CA XCOM Data Transport can transfer all generation data sets within a GDG in a single transfer operation. To do so, specify the GDG by its base name in the request (that is, without a relative generation number).Sending a Specific Generation
CA XCOM Data Transport then transfers all data sets in a single stream, starting with the newest generation and ending with the oldest.
To send a particular generation, give it a GxxxxV00 suffix. This data set is then processed whenever the transfer executes.
