Issue/Introduction

OneClick thick client java console starts with fonts that are too small to read on high-resolution displays.​​

SYMPTOMS:

• OneClick console text and interface elements appear tiny.

• Standard application properties are difficult to access for quick fixes.

• Issue specifically affects the thick client, while the WebApp version displays correctly.

CONTEXT: This occurs when launching the OneClick console (oneclick.jnlp) on Windows systems with high DPI settings.

IMPACT: Users cannot effectively navigate or use the OneClick console interface due to readability issues.

The web based WebApp, which is identical in feature set, is not impacted by this problem.

Environment

Network Observability DX NetOps Spectrum OneClick java thick client

Cause

The Windows High DPI scaling does not automatically adjust the Java-based OneClick client interface, resulting in microscopic fonts on high-resolution monitors.

Resolution

PREREQUISITES:

• Administrative access to the local workstation.

• Knowledge of the Java installation path used by OneClick.

STEPS:

1. LOCATE THE JAVA EXECUTABLE: Find the javaw.exe file used to launch the OneClick JNLP file on the affected system.

   Path Example: C:\Program Files (x86)\Java\jre1.8.0_481\bin\javaw.exe

2. OPEN FILE PROPERTIES: Right-click on javaw.exe and select Properties.
   
   
   
   

3. CONFIGURE HIGH DPI SETTINGS: Navigate to the Compatibility tab.

   ACTION: Click the Change high DPI settings button.

4. OVERRIDE SCALING BEHAVIOR: Check the box for Override high DPI scaling behavior.

   ACTION: In the Scaling performed by dropdown menu, select System or System (Enhanced).

5. APPLY AND RESTART: Click OK, then Apply.

   ACTION: Relaunch the OneClick console to have it use the new settings.
   
   
   
   

VERIFY SUCCESS:

• OneClick console fonts appear at a standard, readable size.

• Interface scaling matches the Windows display settings.
