Configuration of JAVA MIssion Control (JMX) for multiple Managed Servers installed in the same Server

While configuring, the JMX for the developers,

I got the error like:
Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: ; 
nested exception is:
java.net.BindException: Address already in use: JVM_Bind

If we need to monitor the Java using JMC (Java Mission Control), you need 1.7.0 U40 or higher.

Install the latest Java SE Development Kit in your laptop.

Edit the startWeblogic.sh at $DOMAIN_HOME/bin

Hashout all the lines starting from

#START WEBLOGIC to

Before

stopAll

It will be like:

# START WEBLOGIC
echo "starting weblogic with Java version:"

${JAVA_HOME}/bin/java ${JAVA_VM} -version

if [ "${WLS_REDIRECT_LOG}" = "" ] ; then
        echo "Starting WLS with line:"

        echo "${JAVA_HOME}/bin/java ${JAVA_VM} ${MEM_ARGS} -Dweblogic.Name=${SERVER_NAME} -Djava.security.policy=${WL_HOME}/server/lib/weblogic.policy ${JAVA_OPTIONS} ${PROXY_SETTINGS} ${SERVER_CLASS}"


echo $JAVA_OPTIONS

After this, start the weblogic 

Check the port 7091 has been listening

[oracle@voim01ay bin]$ netstat -an |grep 7091

tcp        0      0 :::7091                     :::*                        LISTEN

Restart all the servers

 

From the Client (Desktop) start the Java Mission Control

 Click the Icon mentioned
