[SEGMENT     = { NO | YES}] Only in sender mode           Profile

Option to segment file records in several FPDUs.

  • NO: segmentation "if necessary".

Automatically implemented when a record to be transferred is greater than the maximum size of an NSDU minus 6 bytes. This relates to data FPDUs and not to the other protocol FPDUs.
Remember that the size of NSDUs being sent is negotiated using the SRUSIZE parameter of CFTPROT.

  • YES: "systematic" segmentation.

Implemented by the monitor to complete a "data unit" (NSDU). This option hence relates to all record sizes. This option is only effective if used with the option CONCAT = YES. It is not exclusive with the MULTART = YES option.

SIT profile
     The value SEGMENT = YES is PROHIBITED in SIT profile.

This option is not negotiated.

For the other profiles, it may only be adopted (SEGMENT = YES) with a monitor which supports concatenation of DTF (complete record) and DTFDA (start of record), DTFMA (middle of record) or DTFFA (end of record) FPDUs in a given data unit (NSDU).

In receiver mode, the Transfer CFT accepts the FPDUs of segmented records regardless of the local value of the SEGMENT parameter.
