Creating New MBeans

Objects implemented as MBeans can be registered with the Remote JMX Agent (MBean Server) using the mkdir command. The method is the same as the Local JMX Agent.

Server Configuration

The JMX technology is included with Sun's J2SE 5.0 as documented here.

The Remote JMX Agent can be enabled by starting the JVM with the following properties:

-Dcom.sun.management.jmxremote.port=1090
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

More information can be found in the following articles:

• Getting Started with Java Management Extensions (JMX): Developing Management and Monitoring Solutions.
• J2SE 5.0 in a Nutshell. Monitoring and Manageability.
• Monitoring Local and Remote Applications Using JMX 1.2 and JConsole.

Connecting from wlshell

Once the Remote JMX Agent is configured and running, the following URL can be used with the wlshell connect command:

connect service:jmx:rmi:///jndi/rmi://localhost:1090/jmxrmi

wlshell should be started using J2SE 5.0 and the JMX environment. See the installation section for more information.

Example

In the following example, we will start a Java application with the Remote JMX Agent enabled and connect from wlshell. The example is for the Windows platform.

set JAVA_HOME=c:\jkd1.5.0
cd %JAVA_HOME%
bin\java -Dcom.sun.management.jmxremote.port=1090
           -Dcom.sun.management.jmxremote.authenticate=false
           -Dcom.sun.management.jmxremote.ssl=false -jar demo\jfc\Java2D\Java2Demo.jar

set WLSHELL_HOME=c:\wlshell-2.1.0
cd %WLSHELL_HOME%\bin
wlsh

wlsh [not connected]> connect service:jmx:rmi:///jndi/rmi://localhost:1090/jmxrmi
connecting to MBeanServer(s) as weblogic...done
