Description
The control systems of the LHC experiments are built using the common commercial
product: PVSS II (from the ETM company). The JCOP Framework Project delivers a set
of common tools built on top of, or extending the functionality of, PVSS (such as
the control for widely used hardware, a Finite State Machine (FSM) toolkit, access
control management, cooling and ventilation application) which can be used by all
LHC experiments. The Configuration Database Tool is a part of the JCOP Framework
responsible for management of the configuration data. The tool manages versions of
system, static and configuration data, and uses Oracle DBMS to store it. Typically,
for a single subsystem, thousands of devices and tens of thousands of properties
would need to be managed. The paper describes our experiences from the prototype
phase and the design and implementation of the production version of the tool.
Currently, the implementation is being completed and the tool is being deployed in
the experiments' control systems. In this implementation, effort was put on
providing the functionality requested by the developers, and providing good
performance and scalability.
