Overview

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:

       
Fully Qualified Interface NameIf you use the getMBeanInfo operation in MBeanTypeServiceMBean, supply the following value as this MBean's fully qualified interface name:
weblogic.management.runtime.JVMRuntimeMBean
Factory Methods No factory methods. Instances of this MBean are created automatically.
Access Points You can access this MBean from the following MBean attributes:
    Access Points Inherited from RuntimeMBean Because this MBean extends or implements RuntimeMBean, you can also access this MBean by retrieving RuntimeMBeans. The following attributes contain RuntimeMBeans and its subtypes:
    Subtypes The following MBeans extend or implement this MBean type:
