Managing WebLogic JMX Through JConsole

JConsole is part of JDK, it can be found in $JAVA_HOME/bin directory, and this utility can be used as JMX Console for Managing WebLogic Server, Where you can see the WebLogic Server configuration and invoke various MBean operations, it helps to view and edit the MBean configuration and invoke various JMX Operations on the serverRuntime, serverConnfig and domainRuntime

Here in this post we will see how to setup JConsole for WebLogic Server 10g.

As JConsole is free and distributed with JDK, there is no need of downloading it seperately

We will follow simple steps to setup the JConsole for WebLogic Server

JConsole works in two modes :

1. Local Process Mode -> Checks for Local Java Process to Manage them through console
2. Remote Mode ->We Can provide JMX URL to Manage the Remote Java Process

We Normally Use Remote mode as we need to connect the JConsole to MBean Server of WebLogic Application Server

Step 1. Start WebLogic Admin Server

Fig1. Admin Server ProdDomain Started

Step  2. Login to Admin Console and check the domain configuration

Fig 2. Check Domain's Advanced Configuration as The MBean Servers are enabled or not

Step 3. Check for the Parameters "Compatibility MBean Server Enabled" and "Management EJB Enabled" Status ( They Should be Enabled - By Default They are enabled)

Fig 3 : MBean Servers Enabled (Check box checked by default)

 Step 4. Check The Configuration at Admin Server Side in Ports Tab - > IIOP

Fig 4. IIOP Should be enabled in Admin Server IIOP Port Configuration

Fig 5. Provide some user name and password (preferable weblogic/weblogic), as Anonymous users are not allowed to connect to the JMX MBean Server (Advanced Options in IIOP)

Step 5. Save and Activate Changes - This Needs Restart of the Admin Server.

Fig 6. Change in the IIOP Credentials require restart of the Server Affected

Notice that the logs at the startWebLogic.cmd command window shows as below

The non-dynamic attribute DefaultIIOPPasswordEncrypted on weblogic.management.configuration.ServerMBeanImpl@453b029e([ProdDomain]/Servers[AdminServer]) has been changed. This may require redeploying or rebooting configured entities

change has been made which affects the server AdminServer. This server must berebooted in order to consume this change

Step 6. Restart the Admin Server

Fig 7. Stop the Admin Server (Ctrl+C)

Fig 8. Start the Admin Server (startWebLogic.cmd)

Step 7. Start JConsole - Execute following Steps and Verify the output

Your environment has been set.
C:\bea\wlserver_10.3\server\bin>


C:\bea\wlserver_10.3\server\bin>cd %JAVA_HOME%


Step 8. Execute the following command to invoke "jconsole remote"

jconsole -J-Djava.class.path=%JAVA_HOME%\lib\jconsole.jar;%WL_HOME%\server\lib\wljmxclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote

Step 9. We will get to see the console as below.

Step 10. Please provide Service JMX URL for Admin Server and Specify the MBean Tree to enter as below and their particular JConsole Space.


1. service:jmx:rmi:///jndi/iiop://localhost:7011/weblogic.management.mbeanservers.domainruntime


username/password = weblogic/weblogic

Fig 10. JConsole Domain Run Time Session

2. service:jmx:rmi:///jndi/iiop://localhost:7011/weblogic.management.mbeanservers.runtime
username/password = same as above

3. service:jmx:rmi:///jndi/iiop://localhost:7011/weblogic.management.mbeanservers.edit
username/password = same as above

This is it..!!
