<p>Causes each WebLogic Server instance to initialize the JDK's
platform MBean server and to use the platform MBean server as the
Runtime MBean Server.</p>
<p>As of JDK 1.5, JVMs provide a platform MBean server that local
processes can instantiate. There can be only one instance of the
platform MBean server for each JVM. When a process instantiates
this MBean server, the JVM creates several platform MBeans that
provide monitoring data for the JVM itself.</p>
<p>If you set this attribute to <code>true</code>, each WebLogic
Server instance invokes the method
<code>java.lang.management.ManagementFactory.getPlatformMBeanServer()</code>
and thus causes the initialization of the JVM's MBeans. In this
case, the server's Runtime MBean Server uses the
<code>MBeanServer</code> returned by this method as its
<code>MBeanServer</code>. This makes it possible to access the
WebLogic Server MBeans and the JVM platform MBeans from a single
MBean server. In addition, if you enable the Runtime MBean Server
to be the platform MBean server, local processes in the JVM can
directly access this MBean server through the
<code>MBeanServer</code> interface that
<code>java.lang.management.ManagementFactory.getPlatformMBeanServer()</code>
returns. With this local access, there are no WebLogic Server
security checks to make sure that only authorized users can access
WebLogic Server MBeans. Any application that is running in the JVM
can access any of the WebLogic Server MBeans in the Runtime MBean
Server/JDK Platform MBean Server. <b>Do not use this configuration
if you cannot control or cannot trust the applications that are
running within a JVM</b>.</p>
