To gradually shift passive users off a system ahead of a system outage, fail over the session.
-
Use one of the following methods to perform a failover.
Method Steps Unity UI - From the Unity UI, select Sessions.
- Click , then select Failover.
unityadmin unityadmin> help session failover; Command: SESSION FAILOVER { <unity session id> | <routing name> } Description: Moves the preferred system for the session/routing to the next available system in the ordered list. unityadmin> SESSION FAILOVER <unity session id> | <routing name>;
The best practice is to use a Time Window to shift users automatically ahead of the outage.
You do not need to fail over Managed Sessions, which stop on the Teradata system automatically when it is moved to the out-of-service state.
