Perform a loopback transfer of data on HULFT Square

This section describes how to set a loopback transfer that sends a file from HULFT Square and then receives that file with HULFT Square.

Description

The flow of loopback transfer

The following figure is an example of a loopback transfer. This tutorial explains the steps to perform this loopback transfer.

= Remarks =

In the usual flow of operation, you run scripts from jobs associated with scripts, but in this tutorial on loopback transfer, the script for Send File is executed directly without going through a job.

 

On HULFT Square (outbound), a loopback transfer is performed in the following manner when you execute the script for Send File.

  1. The script for Send File gives the command to HULFT Transfer to execute sending.

  2. The HULFT Transfer service that receives the command to send, based on the HULFT management information, sends the file to the VPC endpoint.

  3. The file is sent from HULFT Square (outbound) to HULFT Square (inbound) connected via PrivateLink.

  4. HULFT Transfer service (inbound) gives a notification to the HULFT Transfer job when it detects the file receipt.

  5. The HULFT Transfer job receives the file based on the HULFT management information and gives the command to run a script that waits for 10 seconds.

  6. The script that waits for 10 seconds is executed.

HULFT Square settings and workflow

For the settings for loopback transfer, configure the inbound settings first, and then configure the outbound settings.
