User ID

Identifies the user ID under whose set of resource access privileges this file transfer is to execute on the source (transfer‑initiating) system.

Up to eight characters: Specifies the user ID under whose set of resource access privileges this file transfer is to execute on the source system.

Notes:

This information is primarily used for third‑party processing. For example, a CA XCOM Data Transport node in New York could request that a CA XCOM Data Transport node in Los Angeles send a file to a CA XCOM Data Transport node in Chicago.
To use this feature, all systems must be identified to VTAM and running CA XCOM Data Transport Version 2 or higher. For conventional (that is, non‑third‑party) file transfers, use this parameter to identify the user that initiated the transfer. This is useful when performing operator tracking and control functions through the CA XCOM Data Transport Operator Control screen.
To send a blank parameter value to the source system, enter “ ”, inserting at least one blank space between the quotation marks. Do this when the source system supplies its own default value for the user ID under whose access privileges the file transfer is to execute on the source system.

Default: TSO user ID
