Detector Controls Meets JEE on the Web

Remote monitoring and controls has always been an important aspect of physics detector controls since it was available. Due to the complexity of the systems, the 24/7 running requirements and limited human resources, remote access to perform interventions is essential. The amount of data to visualize, the required visualization types and cybersecurity standards demand a professional, complete solution. Using the example of the integration of the CMS detector controls system into our ORACLE WebCenter infrastructure, the mechanisms and tools available for integration with controls systems shall be discussed. Authentication has been delegated to WebCenter and authorization been shared between web server and control system. Session handling exists in either system and has to be matched. Concurrent access by multiple users has to be handled. The underlying JEE infrastructure is specialized in visualization and information sharing. On the other hand, the structure of a JEE system resembles a distributed controls system. Therefore an outlook shall be given on tasks which could be covered by the web servers rather than the controls system.
