Overview

Transfer operations take place within the context of a transfer session. A transfer operation is initiated once the Universal Data Mover Manager has established a transfer session with the primary and secondary transfer servers (see Universal Data Mover Transfer Operations). All subsequent transfer operations take place between the primary and secondary transfer servers.

Universal Data Mover transfer sessions can be either two-party or three-party.

Logical Names

When a transfer session is established, the user gives each server a unique logical name. Commands addressed to a particular server reference this logical name.

Two-Party Transfer Sessions

For a two-party transfer session, the Universal Data Mover Manager also acts as the primary transfer server, running in the directory – and under the user ID – under which the Manager was launched. This means that the machine on which Manager resides is the first endpoint of the transfer.

With a two-party transfer session, the secondary server is invoked by the manager / primary server via the Universal Broker. The second endpoint of the transfer session will be on the machine in which the secondary server was spawned. Transfer operations occur between the manager / primary server and the secondary server.

(See the following illustration.)

Three-Party Transfer Sessions

For a three-party transfer session, the Universal Data Mover Manager acts solely as a control point for transfer operations, sending commands to the primary and secondary servers to be executed. Both the primary and secondary servers are spawned via the Universal Broker, and transfer operations take place between the two machines under which these servers are running.
