Provides methods for retrieving information about the Java Virtual Machine (JVM) within with the current server instance is running. You cannot change the JVM's operating parameters while the JVM is active. Instead, use the startup options that are described in the JVM's documentation.
The WebLogic JVM contains only one of these Runtime MBeans:
If the JVM is an instance of a JRockit JDK, then the JVM
contains JRockitRuntime MBean.
Otherwise, it contains the JVMRuntimeMBean.
