With the experience gained in the first years of running the ALICE apparatus we have identified the need of collecting and aggregating different data to be displayed to the user in a simplified, personalized and clear way. The data comes from different sources in several formats, can contain data, text, pictures or can simply be a link to an extended content. This paper will describe the idea to design a light and flexible infrastructure, to aggregate information produced in different systems and offer them to the readers. In this model, a reader is presented with the information relevant to him, without being obliged to browse through different systems. The project consists of data production, collection and syndication, and is being developed in parallel with more traditional monitoring interfaces, with the aim of offering the ALICE users an alternative and convenient way to stay updated about their preferred systems even when they are far from the experiment.

The main role of the ALICE Detector Control System (DCS) is to ensure safe and efficient operation of one of the large high energy physics experiments at CERN. The DCS design is based on the commercial SCADA software package WinCC Open Architecture. The system includes over 270 VME and power supply crates, 1200 network devices, over 1,000,000 monitored parameters as well as numerous pieces of front-end and readout electronics. This paper summarizes the computer infrastructure of the DCS as well as the hardware and software components that are used by WinCC OA for communication with electronics devices. The evolution of these components and experience gained from the first years of their production use are also described. We also present tools for the monitoring of the DCS infrastructure and supporting its administration together with plans for their improvement during the first long technical stop in LHC operation.

The first LHC run period, lasting 4 year brought exciting physics results and new insight into the mysteries of the matter. One of the key components in this achievements were the detectors, which provided unprecedented amounts of data of the highest quality. The control systems, responsible for their smooth and safe operation, played a key role in this success. The design of the ALICE Detector Control System (DCS) started more than 12 years ago. High level of standardization and pragmatic design led to a reliable and stable system, which allowed for efficient experiment operation. In this presentation we summarize the overall architectural principles of the system, the standardized components and procedures. The original expectations and plans are compared with the final design. Focus is given on the operational procedures, which evolved with time. We explain, how a single operator can control and protect a complex device like ALICE, with millions of readout channels and several thousand control devices and boards. We explain what we learned during the first years of LHC operation and which improvements will be implemented to provide excellent DCS service during the next years.
