https://answers.axonivy.com/questions/2411/start-controlcenter-sh-in-headless-mode<p>I try to start the ControlCenter in headless mode, but I hit this error: java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it.</p> <p>There is no XServer on this machine so the error does make sens. Documentation mention we can start it in command line mode: <a href="http://developer.axonivy.com/doc/latest/EngineGuideHtml/misc.html#misc-toolreference-servercontrolcenter">http://developer.axonivy.com/doc/latest/EngineGuideHtml/misc.html#misc-toolreference-servercontrolcenter</a></p> <p>But I can't manage to make it work. I've try various switch and various syntax (-headless, -h) and try to display an help file somehow (-?,?... )</p> <p>I've try to figure it out by looking at ControlCenter.sh content, control.conf and launcher.sh. Didn't find anything relevant. This is on our version of engine 6.0.5. I've try to run the 6.3 version as well (present on this server) and I got the same exception.</p>enFri, 03 Feb 2017 15:11:39 -0500https://answers.axonivy.com/questions/2411/start-controlcenter-sh-in-headless-mode#2421<p>but yes I agree.

If you can't start the ControlCenter on the command line you should update your documentation accordingly: <a href="http://developer.axonivy.com/doc/latest/EngineGuideHtml/misc.html#misc-toolreference-servercontrolcenter">http://developer.axonivy.com/doc/latest/EngineGuideHtml/misc.html#misc-toolreference-servercontrolcenter</a></p> <pre><code>Platform Console support Launcher Windows no bin/ControlCenter.exe Windows yes bin/ControlCenterC.exe Linux yes bin/ControlCenter.sh Table 7.7.
