Grass Valley Aurora Playout v.7.0 - Manual (Page 22)

When the status of a clip changes, the SDB Server updates available status and clip
duration in the Aurora Playout database, which in turn updates the Aurora Playout
application. In addition, when a clip sent from Aurora Edit is associated with a Aurora
Playout placeholder, the SDB Server updates the number of missing items in the
Assignment List Manager and Assignment List Plug-in.
The SDB Server runs on the same computer as the XMOS Server, and optionally on
a second system as a hot standby backup database.
Overview of the XMOS Server
The XMOS Server displays the communication between the Newsroom Computer
System and Aurora Playout.
It runs on the same computer as the primary SDB Server.
