Overview

UDMG (Universal Data Mover Gateway) is a business-to-business MFT (Managed File Transfer) Solution. It provides the capabilities to securely manage File transfers with external business partners (i.e. Customers or Suppliers) and between any endpoint in today's Hybrid-IT infrastructure, on-premises, or in the cloud (public and or private).

This Universal Extension provides the capability to perform file transfer where UDMG is the client and upload or download files to remote partners.

Key Features

Feature	Description
Actions	GET: trigger a File Transfer on UDMG to download a file from a remote partner. PUT: trigger a File Transfer on UDMG to upload a file to a remote partner. MGET: trigger a Wildcard File Transfer on UDMG to download several files from a remote partner. MPUT: trigger a Wildcard File Transfer on UDMG to upload several files to a remote partner. LIST: trigger a Wildcard List File Transfer on UDMG to list the files matching a wildcard pattern on a remote SFTP partner.
File Transfer Control	Capability to pause a partial transfer. Capability to resume a paused transfer. Capability to cancel a transfer (from planned, running, paused, or error status). Capability to retry a failed transfer. Synchronous mode: the task monitors the UDMG transfer and terminates when the transfer is completed (either with success or error). Asynchronous mode: the task registers the UDMG transfer and terminates when the transfer request is acknowledged on UDMG.
Input/Output	Capability for the UAC task author, to retrieve the list of partners from UDMG for a given protocol. Capability for the UAC task author, to retrieve the list of transfer rules from UDMG for a given partner. Monitor the transfer with periodic polling from UDMG and display to output-only fields and extension output.
Other	Support for SFTP, HTTPS, PeSIT, and PeSIT-TLS file transfer protocols.

MFT Server	Text	Yes	UDMG Server URL. This is the URL for the REST API endpoint, the port is configured in the UDMG Server configuration file. For example: http://udmg.company.com:8080/api	Introduced in 1.0.0
MFT Credentials	Credentials	Yes	UDMG Server Credentials. The Credentials definition should be as follows. User Name as "Runtime User". User Password as "Runtime Password". The user must have read permissions for rules and partners, read/write permission for transfers	Introduced in 1.0.0
Source File	Text	Yes	The name of the source file, or the search pattern: PUT: local file GET: remote file MPUT: wildcard pattern for local files MGET: wildcard pattern for remote files LIST: wildcard pattern for remote files	Introduced in 1.0.0
Target File	Text	No	The name of the file on the target system after the transfer, PUT: remote file GET: local file MPUT/MGET/LIST: not used, the field is not displayed.	Introduced in 1.1.0
Partner	Dynamic Choice	Yes	Dynamically fetched list of partner names. The list is restricted to the partners that support the selected Protocol. The user can select the required partner name from a drop-down list.	Introduced in 1.0.0
Rule	Dynamic Choice	Yes	Dynamically fetched list of transfer rules. The list is restricted to the rules that are assigned to the selected Partner. The user can select the required rule from a drop-down list.	Introduced in 1.0.0
Dynamic Retrieval of Partner Account Options	Boolean	No	If enabled, the partner account field will be replaced by a dynamic choice field variant. The default value is false.	Introduced in 1.4.0

Wait for Transfer Completion	Boolean	Yes	By checking this field, the extension monitors the completion of the transfer on UDMG before completing its execution. Actions PUT/GET: Wait for the single transfer to be completed. Actions MPUT/MGET/LIST: Wait for the child file transfers to be completed or not. The extension will always wait for the parent process to be completed successfully, regardless of this configuration attribute. The default value is true.	Introduced in 1.2.0
Polling Interval	Integer	No	The amount of time (in seconds) the task will wait before polling to check the transfer status. Valid values start from 1. The default value is 5.	Introduced in 1.0.0
Max Files to Monitor	Integer	Yes	The number of files, above which no monitor will be done, apart from the successful trigger of the file transfer. In practice, this means that for the actions MGET & MPUT, if a wildcard transfer results in more child transfers than the number indicated, the extension will not check the transfer status of these files, and proceed to completion with a special return code (see corresponding section in this document). The default value is 100.	Introduced in 1.2.0

Dynamic Commands

Command Name	Allowed Task Instance Status	Description
Pause	RUNNING	Issue the pause command on the UDMG transfer. For a wildcard transfer (MPUT or MGET), the pause command is issued for all child transfers on UDMG. Only the eligible children in status PLANNED or RUNNING, are considered. Failure on one transfer does not block the execution of the other transfers.
Resume	RUNNING	Issue the resume command on the UDMG transfer. For a wildcard transfer (MPUT or MGET), the resume command is issued for all child transfers on UDMG. Only the eligible children in status INTERRUPTED or PAUSED, are considered. Failure on one transfer does not block the execution of the other transfers.

Cancelation

When the task instance is canceled on the Controller, a cancel command is issued on the UDMG transfer to attempt a graceful termination.

• If the transfer has no children (PUT, GET, LIST action):
  • Fetch the UDMG transfer status and update the output-only fields.
  • Proceed to cancel the UDMG transfer only when its status is one of PLANNED, RUNNING, INTERRUPTED, PAUSED, or ERROR.
  • Update output only fields when the operation is completed.
• If the transfer has children (MPUT, MGET action): cancel the execution of all of the eligible child transfers on UDMG ( in status PLANNED, RUNNING, INTERRUPTED, PAUSED, ERROR). Failure on one transfer does not block the execution of the other transfers.

Re-Run

When the task instance is re-run on the Controller, a resume command is issued on the UDMG transfer for the file transfers in status ERROR.

• If the transfer has no children (PUT, GET, LIST action):
  • Fetch the UDMG transfer status and update the output-only fields.
  • Proceed to resume the UDMG transfer only when its status is ERROR, otherwise
  • Continue the monitoring until the UDMG transfer is completed.
• If the transfer has children (MPUT, MGET action): resume the execution of all of the eligible child transfers on UDMG (in status ERROR). Failure on one transfer does not block the execution of the other transfers.

UDMG Transfer Error Code

Error Code	Description
TeOk	This is the code used by default. It indicates that there is no error
TeUnknown	Indicates an unknown error (the details of the error can give more information).
TeInternal	Indicates that an internal error occurred in the UDMG Server (lost connection to the database, etc.)
TeUnimplemented	Indicates that the partner wanted to use a valid functionality, but which is not implemented by the UDMG Server.
TeConnection	Indicates that the connection to a remote partner cannot be established. This is the most general error code. A more specific code, if available, should be used.
TeConnectionReset	Corresponds to "connection reset by peer".
TeUnknownRemote	Indicates that the requested remote partner is not known in the UDMG Server database. For security reasons, the external use of this error code (returning this error to a client) is discouraged for incoming connections in favor of TeBadAuthentication, at the risk of leaking information (here, the account exists, but authentication failed).
TeExceededLimit	Indicates that the transfer cannot be processed because the defined limits have been reached (number of connections, number of transfers, etc.)
TeBadAuthentication	Indicates a connection error caused by incorrect authentication data (user, password, certificate, etc. Details of the error can provide more information).
TeDataTransfer	Indicates that an error occurred during data transfer. This is a general error and a more specific code, if available, should be used.
TeIntegrity	Indicates that the integrity check has failed.
TeFinalization	Indicates that an error occurred during the finalization of the transfer.
TeExternalOperation	Indicates that an error occurred during the execution of pre-transfer, post-transfer, or error processing.
TeStopped	Indicates that the transfer was stopped.
TeCancelled	Indicates that the transfer was canceled.
TeFileNotFound	Indicates that the requested file was not found.
TeForbidden	Indicates that the remote partner is not allowed to perform an action.
TeBadSize	Indicates an error related to the size of the file (it exceeds a quota, there is not enough space left on the destination disk, etc.)
TeShuttingDown	Indicates that the UDMG Server is shutting down
