Chapter 3. Operating NetView FTP V2.2.1 MVS - IBM

Mode Name
Use the DLOGMOD keyword to specify the name of an entry in the userdefined
ACF/VTAM logon mode table.
An entry for this mode name must be defined in the logon mode table for the
remote server LU. The default value for the DLOGMOD keyword is FTPBIND.
For further information see “Creating a Logon Mode Table” on page 82.
┌─FTPBIND──────────────────┐ ►►──DLOGMOD= ─┴─logmode-table entry name─┴──────────────────────►◄ Byte Checkpoint Interval
You can specify the byte checkpoint interval as follows:
nK Number of kilobytes between checkpoints; an integer from 1 to 9999.
nM Number of megabytes between checkpoints; an integer from 1 to 999.
0 This indicates that the server does not automatically take checkpoints.
This does not preclude exceptional checkpointing, that is, taking checkpoints
under special situations, such as a line interruption.
The more often checkpoints are taken, the smaller the amount of data that
must be retransmitted should the file transfer be interrupted. However, taking
checkpoints takes time and uses system resources. You must determine an
appropriate value for this parameter empirically.
The default value of 32K is used if BYTECR or TIMECR is not specified.
If you specify a value for this parameter, do not specify a time checkpoint
interval.

Use the TIMECR keyword to specify the time interval at which a server is to
write checkpoints to the checkpoint file when it is the receiving server during a
file transfer.
n Specifies the time in seconds between checkpoints; an integer from 1 to
9999.
0 This indicates that the server should not automatically take checkpoints.
The server will still perform exceptional checkpointing, that is, it will take
checkpoints in special situations, such as a line interruption.
The more often checkpoints are taken, the smaller the amount of data that
must be retransmitted should the file transfer be interrupted. However, taking
checkpoints takes time and uses system resources. You must determine an
appropriate value for this parameter empirically.
