Reliable Transfer Service (RTS) values determine message
reliability parameters, such as the checkpoints to include in data
and the amount of unacknowledged data that can be sent. The options
on the TCP/IP and X.25 X.400 connector Override tab enable
you to change the default X.400 service attributes, such as RTS
values, when using a specific X.400 connector. Use the
Override options to establish communication and manually
configure message transfer to a foreign system only when
Note Changes to the override
values for one connector do not affect message transfer over any
other connector. If you do not specify override values, the X.400
service uses the default values when connecting to a remote X.400
Right-click a connector, and then click Properties.
Click the Override or MTA Override tab, and then
click Additional Values.
Under RTS Values, modify the Checkpoint size (KB)
value, which is the amount of data (in kilobytes) transferred
before a checkpoint is inserted. If an error occurs and the message
must be resent, the process restarts from the most recent
checkpoint. Specify zero for no checkpoint. Decrease checkpoint
size when the link is less reliable.
Under RTS Values, modify the Recovery timeout
(sec) value, which determines the amount of time, after a
broken connection occurs, that the message transport agent (MTA)
waits for reconnection before deleting the information (with its
checkpoints) and restarting the transfer from the beginning.
Under RTS Values, modify the Window Size value,
which is the number of checkpoints that can go unacknowledged
before data transfer is suspended. Specify window size only if the
checkpoint size is greater than zero.
