and forward mode relay
Transfer CFT store and forward mode enables you to route files from one computer
to another via one or more intermediate relays (computers or communication sites).
For example, when sending a file from computer A to computer C, where A and C are
either not directly connected or have a connection problem, the file is routed via
In the same way, a file to be sent to clients that are dependent on
the final receiver may transmit via intermediate systems and be sent on. This transfer
is accomplished using the same protocol from one end to
||This document describes the relay process as it relates to Transfer CFT. You can perform
relay transfers using other Axway products as the intermediary site.
The following illustration features 3 Transfer CFTs, where the protocol may be the
same or different between relay points:
- Source [Initial Sender A]
- Relay [Store and Forward B]
- Target [Final Receiver C]
Routing a transfer via a relay
Implementing the relay
To implement a relay in conjunction with
- Create the flow as described in the
Central Governance User Guide.
- In the SEND command include at a minimum:
- The name of the final receiver, for example TARGET_APPLICATION.
- The name of the flow, for example TEST_RELAY.
- The file to be transferred, for example
|cftutil send part=target_application, idf=test_relay, fname=report
- Optionally you can configure target post-processing to automatically send a reply.
cftutil send type=reply, part=&part, idm=idmr, idt=&idt, msg="Received file successfully."
cftutil end part=&part,idt=&idt
||You can use the script delivered with
Transfer CFT in the
runtime/exec directory/BIN_re.cmd as a basis for your ACK reply from the target application.
||When viewing the final transfer in the CG View Cycle Graph, you will see the number
of Transfer CFTs involved minus 1 entries and that these entries are linked. In the
example above, there would be two entries for the single "report" transfer.
Transfer CFT store and forward mode is only possible from a requester/sender (write transfers
only, not read).
