Transactions in Copper

[Ron Schultz]

I am unclear on the transaction model within Copper and utilizing it to restart failed workflows. As an example, say I have a workflow performing an SFTP, and that SFTP fails due to a connection error. Generally the SFTP connection becomes available in 2-3 minutes. 

a) Is there a way I can retry a Copper workflow from the point it last failed and 

b) control the number of retries performed, and the delay between retries?

Regards,

Ron

Hi Ron,

as I understand your case, you might embed the SFTP call into a retry loop incl. exception handling.

I typically used a wait inside the loop with a time out of second, minutes ...
