Working with the services on the Database Server machine
Working with the services on the Database Server
machine
As well as hosting the System Database, the Database Server machine runs the following
system services under the control of a Server Controller.
• The System Service combines a number of service roles:
– As a data service, it has direct access to the System Database. It handles the transfer to and
from the database of: service configuration information; iTX Desktop start-up information
and layout data; software License information.
– It maintains the security of the iTX system. In this role, it checks the rights of users who log
on at iTX Desktop workstations to use the system resources.
– It holds a register of alerts – i.e. warnings that it and other iTX services can issue. The
warnings relate to potential system conditions that, if they happen, need to be brought to
the attention of system administrators or operators.
•
The Logging Service. All iTX services create logs – records of their actions and
responses to system events. The Logging Service collects these logs and stores them in
the System Database; it also stores copies on the local drive of the Database Server
machine.
• The OPUS 2 Service has two main roles:
– It handles the transfer to and from the System Database of data on all the media files that
are available to users in the iTX system.
– It searches the media data in the System Database. When it finds media items that meet
specified criteria, it returns a list of these for iTX to display and operators to select.
•
The Time Service keeps time for the iTX system. It bases its time on a reference signal
from a time source: by default, a VITC generator if there is one in the system; if there
is no VITC generator, from the PC clock on the Database Server or an external NTP
server.
• The As-Run Logging Service stores the details of schedule events that have taken
place. From this information, iTX can generate as-run logs.
• The Routing Data Service handles the transfer to and from the System Database of
routing information (when iTX is set up to operate a matrix router).
• The Locator Service keeps a register of the iTX services. When one of these services
needs to interact with another, it gets the connection details from the Locator Service.
• The iTX Software Updater. More details , page 297.
