title: How to maintain Selenium Grid?
body: <p>I have many VMs which are used as part of Grid. Some as RC and some as Hub. Due to the large number of VMs that is being used, it is a big task to maintain the grid now. To change the RC to point to a different hub, I will have to </p>
  
  <ol>
  <li><p>login to that machine </p></li>
  <li><p>kill the current RC</p></li>
  <li><p>run the java command again with a different hub URL</p></li>
  </ol>
  
  <p>Yes, I can use a batch script to restart all the machines. But what if I just want to change just one machine? </p>
  
  <p>Is it possible to create an application using JAVA RMI which can run the required commands to kill, start, restart the RCs or Hub? Has anyone ever tried to create such an application? </p>
