Transfer Control (XTC)

CA XCOM Data Transport Transfer Control (XTC) parameters are used to handle dependencies between multiple transfers. For example, one transfer must complete in a certain way before another can start. They provide the means by which interdependent transfer requests can be defined and processed as a single group. A transfer request belonging to such a group can cause another transfer request in the same group to be held, purged, or released (either conditionally or unconditionally) from the transfer request queue.

The following XTC parameters have been added:

• HOLD—Prevents a TYPE=SCHEDULE transfer from starting until explicitly released.
• HOLDCOUNT—Associates a number with a transfer request that is incremented or decremented by the successful or unsuccessful completion of other transfer requests. As long as the number is greater than 0, the transfer is not released.
• XTCERRDECR—Specifies the transfer requests for which the HOLDCOUNT parameter value is decremented when the current transfer completes unsuccessfully.
• XTCERRINCR—Specifies the transfer requests for which the HOLDCOUNT parameter value is incremented if the current file transfer fails.
• XTCERRPURGE—Specifies the transfer requests to be purged if the transfer concludes unsuccessfully.
• XTCERRREL—Specifies the transfers to be released if the current transfer completes unsuccessfully.
• XTCGOODDECR—Indicates an XTCNET job whose hold count decrements if the file transfer completes successfully.
• XTCGOODINCR—Indicates the transfer requests whose HOLDCOUNT parameter is incremented when the current file transfer completes successfully.
• XTCGOODPURGE—Specifies the transfer requests to be purged when the current file transfer completes successfully.
• XTCGOODREL—Specifies the transfer requests to be released if the current file transfer concludes successfully.
• XTCJOB—Defines the name of a transfer request belonging to the group of interdependent transfer requests named through the XTCNET parameter.
• XTCNET—Defines the name of a group of interdependent transfer requests.
