Configuring the System Service to use the back-up Database Server
When you use Microsoft SQL Server mirroring functionality to keep the back-up System
Database synchronised with the main System Database, you need to configure the System
Service on the main Database Server machine to use the back-up Database Server.
You do this by entering the name of the back-up machine in the Backup Database Server box in
the Database Configuration dialog:
The dialog appears when you install the Database Server module. You can display it after
installation by running the System Service Configuration tool (ObjectDatabaseConfig.exe).
The tool is stored in the folder:
C:\Program Files (x86)\iTX 2.0\Services\SystemServiceConfig
Running a back-up Output Server
Master and slave channels
Two Output Servers, one main and one back-up, operate a pair of master-slave playout
channels: the main Output Server provides the master channel; the back-up Output Server, the
slave channel. iTX plays out the schedules in both channels at the same time.
Normally, the output signal from the main Output Server is delivered to the transmission
system through a matrix router; the back-up Output Server is connected as an alternative
router source. The diagram shows this arrangement:
The router destination to which the transmission system is connected is used to define the
master channel – i.e. the channel that is routed to this destination is the master channel. You
specify the destination when configuring the channel. More details , page 146.
