Outbound File Transfer
An outbound file transfer is triggered by a scheduled event configured in the ActiveTransfer Server or when the ActiveTransfer Server directly invokes the wm.mft.schedule:executeEventservice service.
To configure failover support for outbound file transfers:
*In the copy or move action configuration on the Event Management page, select Retry failed copies and Resume transfer from the point of interruption options.
Select this option...
To...
Retry failed copies
Retry a failed copy or move operation for the specified number of times.
Resume transfer from the point of interruption
Resume an interrupted copy or move operation from the point of interruption.
For additional details, see Copying or Moving Files.
*If you are transferring files by way of a virtual folder instead of directly connecting to an external server, configure the following additional options for the virtual folder in the Administration > Integration > Managed File Transfer > Virtual Folder Management page before you use the virtual folder in a move or copy action:
*High Availability Download Recovery, if you want ActiveTransfer Server to recover from a download that was not completed.
*High Availability Upload Recovery, if you want ActiveTransfer Server to recover from a upload that was not completed.
The High Availability Upload/Download Recovery options provide recovery from short drops in connections (30 to 60 seconds) during file transfers. ActiveTransfer Server maintains an internal buffer for the transfer-in-progress which is used for automatic retries to re-connect to the external server if the connection goes down. And, when the connection is re-established, ActiveTransfer Server resumes the file transfer from the point of failure. This automatic resume is triggered by ActiveTransfer Server without the intervention of the requestor ensuring uninterrupted file transfer. For additional details on configuring these options, see Associating a Virtual Folder with a Physical Folder Location.
The outbound file transfer scenario is shown in the following illustration:
Label
Description
1
A scheduled event configured in ActiveTransfer Server triggers a file transfer request to an external server.
2
The file transfer request is configured to transfer files to or from an external server, or transfer files to a virtual folder pointing to an external server configured in ActiveTransfer Server and pointing to an external server.
If the connection between an ActiveTransfer Server and a remote server goes down when a file transfer is in progress, ActiveTransfer provides failover support as follows:
*You can configureActiveTransfer Server to try to re-establish the connection with the remote server. You can set the number of retries when you configure a copy or move action in a post-processing or scheduled event. The default value for the number of retries is Unlimited. Once the connection with the remote server is established, you can configure the ActiveTransfer Server to resume file transfer from the point of failure or from the beginning.
*You can configure the High Availability Upload/Download Recovery options in a virtual folder. If selected, these settings provide automatic resume of interrupted file transfer requests from the point of failure. This process is triggered by ActiveTransfer Server without the requestor’s knowledge or intervention.
