Description: 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. 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. If you set this attribute to true, each WebLogic Server instance invokes the method java.lang.management.ManagementFactory.getPlatformMBeanServer() and thus causes the initialization of the JVM's MBeans. In this case, the server's Runtime MBean Server uses the MBeanServer returned by this method as its MBeanServer. 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 MBeanServer interface that java.lang.management.ManagementFactory.getPlatformMBeanServer() 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. Do not use this configuration if you cannot control or cannot trust the applications that are running within a JVM.
