17. XFEL The European X-Ray Laser Project 17 optional plugins Management (Updates) local user has restricted access to new/updated plugins by default the user's role defines the range of possibilities for the user it's not allowed to update CSS with non-approved plugins by default the user can't add plugins to CSS by default update is triggered by central repository

18. XFEL The European X-Ray Laser Project 18 Update mechanism encapsulate the existing Update-Plugin The non-privileged operator must not have the possibility to manually update the local installation of the CSS-System. The running instance will register itself at the central repository to get updated. The privileged operator may start an update-process with non-approved features (with explicit login). update local plugins and features All plugins and features of the local CSS-System will be updated automatically without any interaction by the operator. The update- process is inited by a respository-admin.

19. XFEL The European X-Ray Laser Project 19 Update mechanism grant password-protected access to central repository for beta-updates Usually, the operator will init the automatic update- process: all available – approved – updated plugins and features are installed. With a login and password, the operator may also browse the repository and update the local CSS-installation with non-approved – maybe unstable – plugins and features. CSS running 24/7 These systems will be updated by remote. Running instances will be restartet – if needed.
