Controlling File Transfer
The current Secure File Transfer Protocol (SFTP) does not transfer
any information about the files to be transferred, only the file
contents as a byte stream. This is sufficient for Unix-type files if the
sender and receiver use the same CCS.
SSH Tectia Server for IBM z/OS needs more information: which transfer format to
use, what code sets are involved, and what the file characteristics
are. SSH Tectia introduces some extensions to SFTP and the information can
be relayed by using the Site commands of
sftpg3. Alternatively file transfer profiles can be
For command descriptions, see the
command on the
sftpg3 man page and the
--src-site options on the
scpg3 man page.
A file transfer profile is a mechanism for pre-configuring different
types of secure file transfers. Both the mainframe clients (
sftpg3) and the server use the same profile mechanism. There are
two types of profiles: named profiles and filename-matched profiles.
