title: What is the JVM memory allocated by default
body: <p>In my <code>Catalina.bat</code> file </p>
  
  <pre><code>:doStop
  shift
  set ACTION=stop
  set CATALINA_OPTS=
  goto execCmd
  </code></pre>
  
  <p><code>Xms</code> has not specified , so what would be the memory allocated by default ??</p>
  
  <p>is there any specific command to check the allocation given to the jvm ?</p>
