title: Jmeter - Can I change a variable halfway through runtime?
body: <p>I am fairly new to <code>JMeter</code> so please bear with me. </p>
  
  <p>I need to understand whist running a <code>JMeter</code> script I can change the variable with the details of <code>"DB1" to then look at "DB2"</code>.</p>
  
  <p>Reason for this is I want to throw load at a <code>MongoDB</code> and then switch to another <code>DB</code> at a certain time. <code>(hotdb/colddb)</code></p>
