Checkpoint interval (CHKPTINT)

Use checkpoint interval to set the number of records that are sent before a restart marker is sent. Checkpoint markers are sent to clients who use EBCDIC block mode or EBCDIC compress mode during data set retrieval. If the FTP connection fails while using the checkpoint intervals, the transfer can be restarted at the last checkpoint by reconnecting to the FTP server and issuing the restart command.

Check the box labeled "Use checkpoint" to activate this function and optionally you may modify the number of records.

Note: If you plan to have clients that do not support the restart marker, do not set the checkpoint interval, but instead use the FTP SITE/LOCSITE command checkpoint interval for individual clients.
