Figure 1-3 RC session data flow in a multi-TMR environment
Based on Figure 1-3, here we detail each step from the time when the Tivoli
Administrator opens an RC Tool from a Collection located in the HUB TMR until

The legend used in Figure 1-3 is explained as follows:
A The Tivoli Administrator must first open an RC Tool to be able to
select a Target from a list. As the RC Tool is located in a Policy

Tool is available in the HUB TMR.
B As soon as the RC Tool on the Spoke is opened, the Spoke Remote
Control Server needs to validate the Controller by checking:
– If the Controller is an Endpoint.
