Browsing Runtime MBeans

Similar to the configuration information, WebLogic Server runtime MBeans are arranged in a hierarchical data structure. When connected to an Administration Server, you access the runtime MBean hierarchy by entering the serverRuntime or the domainRuntime command. The serverRuntime command places WLST at the root of the server runtime management objects, ServerRuntimeMBean; the domainRuntime command, at the root of the domain-wide runtime management objects, DomainRuntimeMBean. When connected to a Managed Server, the root of the runtime MBeans is ServerRuntimeMBean. The domain runtime MBean hierarchy exists on the Administration Server only; you cannot use the domainRuntime command when connected to a Managed Server.

For more information, see ServerRuntimeMBean and DomainRuntimeMBean in the WebLogic Server MBean Reference.

Using the cd command, WLST can navigate to any of the runtime child MBeans. The navigation model for runtime MBeans is the same as the navigation model for configuration MBeans. However, runtime MBeans exist only on the same server instance as their underlying managed resources (except for the domain-wide runtime MBeans on the Administration Server) and they are all un-editable.
Navigating and Displaying Runtime MBeans Example

The commands in Listing 5-3 instruct WLST to connect to an Administration Server instance, navigate, and display server and domain runtime MBeans.
