||
In modern scientific instruments like ALBA, ELETTRA or Synchrotron Soleil the monitoring and tuning of thousands of parameters is essential to drive high-performing accelerators and beamlines. To keep tracks of these parameters and to manage easily large volumes of technical data, an archiving service is a key component of a modern control system like Tango [1]. To do so, a high-availability archiving service is provided as a feature of the Tango control system. This archiving service stores data coming from the Tango control system into MySQL [2] or Oracle [3] databases. Tree sub-services are provided: An historical service with an archiving period up to 10 seconds; a short term service providing a few weeks retention with a period up to 100 milliseconds; a snapshot service which takes "pictures" of Tango parameters and can reapply them to the control system on user demand. This paper presents how to obtain a high-performance and scalable service based on our feedback after years of operation. Then, the deployment architecture in the different Tango institutes will be detailed. The paper conclusion is a description of the next steps and incoming features which will be available in the next future.
