Cause

Standardinställningen monitoring-app.properties för HTTP-huvudets storlek är 8 kB. HTTP-standardhuvudet kanske inte räcker för att hantera alla rubriker med en stor Active Directory-användare eller gruppinställningar.

Resolution

Öka inställningen monitoring-app.properties HTTP-huvudstorlek på NetWorker-servern.

  • Stoppa "NetWorker Management Web UI Server" tjänst:
Linux: 
sudo systemctl stop nwui
Windows: 
net stop nwui
  • Öppna monitoring-app.properties Fil i en textredigerare:
Linux:  
sudo vi /nsr/nwui/monitoring/app/conf/monitoring-app.properties
Windows: 
notepad C:\Program Files\EMC NetWorker\nwui\monitoring\app\conf\monitoring-app.properties
  • Lägg till en ny rad för server.max-http-header-size alternativ med värdet 32 kB
server.max-http-header-size=32KB
  • Spara ändringarna i monitoring-app.properties fil.
  • Starta "NetWorker Management Web UI Server" tjänst:
Linux: 
sudo systemctl start nwui
Windows: 
net start nwui
