Alternatively you can set the properties in the management.properties file located in the installation directory of the
WebSphere application serverAppServerjavajrelibmagagement.

Step3: Restart the JVM

Step4: Monitor the Websphere process using Visual VM

Go to the Oracle JDK installation directory.
Change to the bin directory and execute jvisualvm.exe.

In VisualVM start a new connection by selecting File – Add JMX Connection.
Enter localhost:1099 in the input field and click OK. VisualVM will connect to WebSphere. In the navigation tree on the left a new node should appear.
Double-click this node to start profiling.
