When it is time to proceed to the Unity server with the active sequencer, you can fail over the sequencer to the second Unity server. This causes an interruption because the standby sequencer must become active, wait for the other components to re-connect, and then initiate a recovery of the managed Teradata systems.
  1. To put all Teradata systems in an out-of-service state, select Components, then select Endpoints.
  2. Click "" to fail over the sequencer process.
    You can also use the unityadmin command SEQUENCER FAILOVER.
