Question
HULFT Square has auto resend feature.
What conditions must be met for auto resend to be carried out?
Answer
As a prerequisite, you need to set a value of 1 or more in "Socket Error Retry Count" of the HULFT Transfer Service to enable auto resending. If a communication error occurs during a file transferring process, HULFT Square will attempt to resend the file(s) for this number of times.

Auto resend is carried out when a specific error code is returned during a file transferring process.
The error codes that are subject to auto resend are as follows:
Error codes when a communication error occurs
If a communication error occurs during sending a file, one of the following detail codes is recorded in the Send Log:
- 208 : Reading of the communication socket failed.
- 212 : Writing of the communication socket failed.
Error codes when a failover occurs on the receiving host and the host is forcibly stopped
If a failover occurs on the receiving host, one of the following error codes is recorded in the Send Log:
- 250-591
-
- 250 : Status code of the Send process (server error)
- 591 : Status code of the host on the receiving side indicating that the host was forcibly stopped
For details, refer to Error Codes and Messages of the host type on the receiving side.
A forced stop due to a failover on the receiving host can be detected if the following products are installed on the host:
-
HULFT for UNIX/Linux
-
HULFT for Windows Ver.7.3.0 or higher
Error codes when a data verification error occurs on the receiving-side host
If a data verification error occurs on the receiving host, one of the following error codes is recorded in the Send Log:
- 250–535
-
- 250 : Status code of the Send process (An error occurred on the receiving side)
- 535 : Status code of the receiving-side host indicating that a data verification error occurred
For details, refer to Error Codes and Messages of the host type on the receiving side.
If the transferring process fails due to a cause other than the above, auto resend will not be carried out.
