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.

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 of 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.

Import Universal Template

To use the Universal Template, you first must perform the following steps.

This Universal Task requires the Resolvable Credentials feature. Check that the Resolvable Credentials Permitted system property has been set to true.
To import the Universal Template into your Controller, follow the instructions here.
When the files have been imported successfully, refresh the Universal Templates list; the Universal Template will appear on the list.

Modifications of this integration, applied by users or customers, before or after import, might affect the supportability of this integration. For more information refer to UDMG File Transfer#IntegrationModifications.

Configure Universal Task

For a new Universal Task, create a new task, and enter the required input fields.

Input Fields

The input fields for this Universal Extension are described below.

Field	Input type	Default value	Type	Description
Action	Required	PUT	Choice	Action performed upon the task execution. Available actions: GET PUT MGET MPUT LIST
Protocol	Required	SFTP	Choice	The transfer protocol. Available values: SFTP HTTP HTTPS PeSIT PeSIT-TLS Note The protocol serves as a filter for the Partner list. The actual protocol for the file transfer is the one that is configured on UDMG for the selected Partner
MFT Server	Required	-	Text	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.stonebranch.com:8080/api
MFT Credentials	Required	-	Credentials	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
Source File	Required	-	Text	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
Target File Introduced in version 1.1.0	Optional	-	Text	The name of file on the target system after the transfer, PUT: remote file GET: local file MPUT/MGET/LIST: not used, the field is not displayed.
Partner	Required	-	Dynamic Choice	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.
Rule	Required	-	Dynamic Choice	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.
Partner Account	Required	-	Text	The name of the account to use for the connection to the selected Partner. The account credentials are configured on UDMG.
Wait for Transfer Completion Introduced in version 1.2.0	Required	True	Boolean	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 transferred 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.
Polling Interval	Optional	5	Integer	The amount of time (in seconds) the task will wait before polling to check the transfer status. Valid values from 1.
Max Files to Monitor Introduced in version 1.2.0	Required	100	Integer	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).

Task Execution

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 for 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 for 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 for 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
- Continute 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 for 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	Means "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 cancelled.
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

Changelog

ue-mft-transfer-1.3.0 (2023-09-29)

Deprecations and Breaking Changes

Breaking Change: "Polling Interval" minimum value is set to 1, a value of 0 could cause an infinite loop (#33815).

Enhancements

Added: new LIST action to retrieve the names of the files matching a wildcard pattern on a remote SFTP partner (#33358).
Added: Logging of dynamic command processing in the agent log with TRACE level (#32993).
Added: MGET/MPUT: error is raised when monitoring of child transfers is skipped because the list is greater than "Max Files To Monitor": CHILD_TRANSFERS_NOT_MONITORED_WARNING with exit code 90 (#33065).
Added: Support for throttling the MGET/MPUT monitoring with the environment variable UDMG_CLIENT_MAX_THROTTLE_RATE. It sets the maximum number of calls per second to the UDMG API during the monitoring phase. Default is 60 (#33432).
Changed: "Target File" only visible for GET & PUT actions (#33367).
Changed: After a dynamic command, the extension will terminate immediately if the transfer is already completed (#32989).
Changed: "Polling Interval" field is always visible, as it is still used to check for parent transfer completion (#32994).
Changed: MGET/MPUT: "Transfer Progress" is only updated when a child transfer is completed (DONE, ERROR, CANCELLED) (#33815).
Changed: Sorting of the "Action" list (#33064).

Fixes

Fixed: Exit code to be 11 in case of 404 API errors (#28881).
Fixed: Extension finishes successfully after unexpected transfer CANCELLED status (#29248).
Fixed: Fix Task Cancel to also process child transfers that are in ERROR status (#33804).
Fixed: Proper catching of UDMG API errors during wildcard transfer monitoring (#33310).

ue-mft-transfer-1.2.0 (2023-05-09)

Deprecations and Breaking Changes

Breaking Change: Transfer Progress output only field is changed to text value (#32195)

Enhancements

Add: Support Wildcard Transfer (#32198, #32195, #32201)
1. New actions "MPUT" and "MGET" for wildcard transfers:
  - support for wildcard in source file parameter,
  - creation of wildcard transfer on UDMG,
  - monitoring of child transfers on UDMG,
  - tabular report on STDOUT with final child transfer status,
  - short summary report in EXTENSION output,
  - PAUSE, RESUME, and CANCEL commands are propagated to child transfers
2. "Transfer Progress" output field is redefined to show human readable value
  - size in KB, MB, or GB for single transfer,
  - "x out of y files" for wildcard transfer
3. "Max files to monitor" parameter: limit the number of child transfers that are monitored by the task instances, 100 by default.
4. "Wait for transfer completion" parameter: task instance only returns when the transfer is completed (with DONE or CANCELLED status) on UDMG.
  For wildcard transfers, only returns when all child transfers are completed. Activated by default.
Add: Refresh task instance output with re-run (#32463)
Add: Keep UC task instance ID in UDMG file transfer metadata field udmg_ue_task_uuid (#30931)
