When Unity is configured with two Teradata systems, each of the two regions have the following processes:
  • Endpoint
  • Sequencer
  • Watchdog
  • Recovery log
  • Two dispatchers

Each Unity system also has a Unity repository with configuration settings and a data dictionary.

Each Teradata system has a transaction table that is created as part of system activation.



Each process is assigned a region. To provide high availability, each region may contain failover copies of processes from other regions.
