Hi, I recommend that you perform the following checks before creating a JMX connection in Visual VM: * Virtual DataPort Server should be up and running on port 9999. * If your machine has several IP’s, be sure that you have set correctly the RMI host in the Denodo Platform Control Center. You can find that by navigating to Configure > JVM Options > RMI host. * Be sure that you are providing valid security credentials. * If you have Virtual DataPort Server running on another machine, then instead of using "localhost" you need to provide the IP address or machine name. * If you have proxy configured on your system and you are using Visual VM, then you need to define it by navigating to Tools>Options>Network.   If you continue to face the same error even after performing the above checks then you can probably try connecting to Virtual DataPort Server using jconsole. I was able to use this official documentation link and add a JMX connection in my Visual VM [Using JavaTM VisualVM](https://community.denodo.com/docs/html/browse/6.0/vdp/administration/monitoring_the_virtual_dataport_server/monitoring_with_a_java_management_extensions_jmx_agent/using_javatm_visualvm) I hope this helps you!

I followed all the steps you mentioned and gone through Using JavaTM VisualVM. I was able to give the JMX connection to Denodo on my local computer. But I am facing this issue when I am trying to install it on the upper environments (QA and UA)

I also tried to create a delimited file instead of using the Visual VM. Now I am getting the following error while trying to run "denodomonitor_startup.bat" "Communication error: Failed to retrieve RMIServer stub: javax.naming.Communicati onException [Root exception is java.rmi.ConnectIOException: non-JRMP server at r emote endpoint] Connection error: Failed to retrieve RMIServer stub: javax.naming.CommunicationE xception [Root exception is java.rmi.ConnectIOException: non-JRMP server at remo te endpoint] Connection error: Failed to retrieve RMIServer stub: javax.naming.CommunicationE xception [Root exception is java.rmi.ConnectIOException: non-JRMP server at remo te endpoint] Connection error: Failed to retrieve RMIServer stub: javax.naming.CommunicationE xception [Root exception is java.rmi.ConnectIOException: non-JRMP server at remo te endpoint] vdp resources monitor finished Connection error: Failed to retrieve RMIServer stub: javax.naming.CommunicationE xception [Root exception is java.rmi.ConnectIOException: non-JRMP server at remo te endpoint]" How can I overcome this error.

Hi, Before starting up the Denodo monitor you need to check the connection parameters to Virtual DataPort Server in the configuration file: <DENODO_MONITOR>/conf/ConfigurationParameters.properties If you have recently modified the IP address/host name of the machine, port number and authentication details you need to reflect the same in the properties "vdp.jmx.host","vdp.jmx.port","vdp.jmx.user" and "vdp.jmx.password". I have found more useful information in the [Denodo Monitor]( https://community.denodo.com/docs/html/browse/6.0/vdp/administration/monitoring_the_virtual_dataport_server/denodo_monitor/denodo_monitor) section of the documentation. If you are a user with support access and you continue having problems dealing with the Denodo Monitor, I would recommend you to raise a support case in the Denodo Support Site (http://support.denodo.com) by attaching the complete log file. Your issue would be analyzed in detail by the Denodo Support team and they will help you to find the solution. Hope this helps you!
