How to connect to NetWorker Management Console after NetWorker Upgrade to 19.13 or later

Upgrading to NetWorker version 19.13 brings changes to the runtime environment, often preventing the NetWorker Management Console (NMC) from connecting. Newer NMC releases require Java Development Kit (JDK) 17 and utilize NetWorker Runtime Environment (NRE) 17.x. Older configurations relied on NRE 8.0.x, and the two versions cannot coexist on the same system. The traditional NMC Launcher shortcut is no longer available in the latest release. This tutorial provides clear, step-by-step instructions to resolve the connection problem by configuring OpenWebStart. Watch the full walkthrough to see exactly how to launch the settings file, adjust the JVM Manager, update the required configuration text file, and download the new console launcher to regain access to your environment. Configuration lines required for the javaws.vmoptions file: -XX:+IgnoreUnrecognizedVMOptions --add-modules=java.se.ee -Xms256m -Xmx2048m

When you try to open the NetWorker Management Console after upgrading to version 19.13 or later and cannot connect, here is how to fix this. The main cause of this issue is that the newer NMC versions uses NRE 17.x which requires Java Development Kit 17. You cannot have both NRE8.0.x and NRE 17.x installed.

There is no “NMC Launcher” shortcut in NRE 17.x. To resolve this issue, you need to install the new runtime environment and configure OpenWebStart. When upgrading, the new NetWorker Runtime Environment 17.0.x is installed too. Launch OpenWebStart using the .exe file from the NRE installation path and finish the initial setup.

Navigate to “C:\Program Files\OpenWebStart” and launch the OpenWebStart settings file named “itw-settings.exe”. Navigate to “JVM Manager” and click “Add Local” then navigate to the NRE Java Installation and click “Open”. In JVM Manager click “Settings”. Under the Update Strategy section, select “Do not download any version”, then click “OK”. In JVM Manager click “Apply”. Navigate to Updates and uncheck the “Check automatically for updates” checkbox to deactivate it.

Click “Apply” and “Ok” to Save and close the settings file. Navigate to the OpenWebStart installation folder and open the “javaws.vmoptions” file with a text editor. Add the necessary configuration lines exactly as shown, then save the file. You can find these also in the video description and the Knowledge Base Article 000334281. Now you need to download the new launcher.

Open a web browser and go to “https://” followed by your NMC server address and port 9000. Accept any security warnings related to the self-signed certificate to proceed. Click “Launch Console”. This downloads a file named “gconsole.jnlp”. Move this file to a location of your choice and use it to launch the NetWorker Management Console.

In the ObenWebStart console click “Yes” to trust the NMC Sever Certificate. Wait for the configuration to complete and click “Run”. Then login to the NMC. For detailed information please refer to the Dell Knowledge Base Article 000334281. Thank you for watching.
