The CMS DCS (Detector Control System) will use a commercial SCADA (Supervisory Controls And Data Acquisition) product. The 4 LHC experiments at CERN have selected PVSS II from the company ETM as SCADA product. The SCADA has its own database, which is suitable for storing conventional controls data as voltages, temperatures, pressures. In LHC experiments calibration data and FE (Front-End) electronic configuration need to be stored. The amount of these data is too large to be stored in the SCADA database [1]. Therefore another database will be used for storing such data. This database should be completely integrated into the SCADA. This means that the database should be accessible from the SCADA and the SCADA features, e.g. alarming, logging, should be available for data stored in the database. For prototyping an Oracle 8i was selected as external database. The development of this calibration constants and FE electronics configuration controls system is being done in close collaboration with the CMS tracker group and JCOP (Joint Controls Project)[2].
