title: Increase memory for jMeter on command line
body: <p>I am running jMeter from the command line on a Mac. Today it threw an Out of memory, heap space error....</p>
  
  <pre><code>newbie$ sh jmeter.sh
  Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space
  at java.awt.image.DataBufferInt.&lt;init&gt;(DataBufferInt.java:41)
  at java.awt.image.Raster.createPackedRaster(Raster.java:455)
  </code></pre>
  
  <p>I know I need to increase the memory allocated to it, but not sure how.  I looked at this post <a href="https://stackoverflow.com/questions/25976985/unable-to-increase-heap-size-for-jmeter-on-mac-osx">Unable to increase heap size for JMeter on Mac OSX</a> and found that jMeter script file in the bin folder it mentions and made the below updates..</p>
  
  <pre><code>HEAP="-Xms1024m -Xmx2048m"
  NEW="-XX:NewSize=512m -XX:MaxNewSize=1024m"
  </code></pre>
  
  <p>But I am still getting the out of memory error. Do I just need to give it more or am I changing in the wrong place? Could it be I need to restart my whole machine?</p>
