Cause

This issue was raised to NetWorker engineering under defect NETWORKER-108676.

The NMC runtime environment (for example, NetWorker Runtime Environment) is using a non-US locale.

Resolution

This issue is addressed in NetWorker 19.12.0.2, upgrade to this release or later for a fix.


Workaround:

Change the runtime environment locale to US on the host used to access the NMC.

  1. Open Windows File explorer window and browse to the NetWorker Runtime Environment (NRE) installation path:
C:\Program Files\NRE\java\jre#.#.#_###\bin

NOTE: The Java Runtime Environment (JRE) folder includes different numbers depending on the NetWorker Runtime Environment version installed. If you are using Oracle licensed Java instead of NRE, browse to the location of your JRE bin directory.
  1. Open javacpl.exe from the JRE bin directory.
  2. In the Java Control Panel, go to the Java tab.
  3. Click View to open the JRE Settings.
  4. Select the JRE that you want to configure and click the Runtime Parameters column.
  5. Add the following parameters to set the locale to English (United States):
-Duser.language=en -Duser.country=US
For Example:
Java runtime environment locale settings
  1. Click OK to save the changes.

  3. Close the Java Control Panel.
  4. If the NMC is already open, close the current session and relaunch the NMC.
