Cause

L'impostazione predefinita monitoring-app.properties per la dimensione dell'intestazione HTTP è 8 KB. L'intestazione HTTP predefinita potrebbe non essere sufficiente per contenere tutte le intestazioni con un utente o un gruppo di impostazioni Active Directory di grandi dimensioni.

Resolution

Aumentare l'impostazione delle dimensioni dell'intestazione HTTP monitoring-app.properties sul server NetWorker.

  • Arrestare il "NetWorker Management Web UI Server" servizio:
Linux: 
sudo systemctl stop nwui
Windows: 
net stop nwui
  • Aprire il file monitoring-app.properties file in un editor di testo:
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
  • Aggiungere una nuova riga per server.max-http-header-size opzione con valore di 32 KB
server.max-http-header-size=32KB
  • Salvare le modifiche apportate a monitoring-app.properties di NetWorker.
  • Avviare il "NetWorker Management Web UI Server" servizio:
Linux: 
sudo systemctl start nwui
Windows: 
net start nwui
