Cause

O processo de monitoramento precisa de permissões para o keystore do NWUI preencher as informações do painel de controle. A coluna "monitoringdbpasswordalias" O alias foi removido do arquivo de keystore do NWUI (nwui.keystore) e o processo de monitoramento não pode ser autenticado. A causa do desaparecimento "monitoringdbpasswordalias" O alias não é conhecido.

O keystore NWUI deve mostrar o "monitoringdbpasswordalias" cognome:

C:\>"C:\Program Files\NRE\java\jre1.8.0_321\bin\keytool.exe" -list -keystore  "C:\Program Files\EMC NetWorker\nwui\monitoring\app\conf\nwui.keystore"
Enter keystore password:
Keystore type: PKCS12
Keystore provider: SunJSSE

Your keystore contains 3 entries

emcauthctomcat, MONTH DD, YYYY, PrivateKeyEntry,
Certificate fingerprint (SHA-256): B2:D3:E1:8D:65:12:8D:51:3F:EA:CA:41:9C:A9:93:C2:21:8D:A7:A7:25:F8:CE:69:F9:21:90:55:37:43:6E:4E

monitoringdbpasswordalias, MONTH DD, YYYY SecretKeyEntry,

O ambiente afetado não tem o "monitoringdbpasswordalias" cognome:

C:\>"C:\Program Files\NRE\java\jre1.8.0_321\bin\keytool.exe" -list -keystore  "C:\Program Files\EMC NetWorker\nwui\monitoring\app\conf\nwui.keystore"
Enter keystore password:

Your keystore contains 2 entries

Resolution

A coluna "monitoringdbpasswordalias" O alias deve ser recriado no repositório de chaves do NWUI. A senha do keystore do NWUI é necessária para autenticar no arquivo do keystore do NWUI. No procedimento, a senha do keystore do NWUI deve ser usada no lugar da <senha>.
 

  1. Abra uma janela do prompt de comando com a opção "Executar como administrador".
  2. Crie uma cópia do pg_hba.conf:
copy "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf" "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf_original"

 

  1. Abra o arquivo pg_hba.conf com um editor de texto:
notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf"
  • Altere o MÉTODO de "md5" para "trust" para todos os usuários não comentados na parte inferior do arquivo
  • Salve as alterações em pg_hba.conf
  1. Interrompa o "NetWorker WebUI Database" e o "NetWorker Web Management UI Server" services: net stop nwui
  2. Inicie os serviços "NetWorker WebUI Database" e "NetWorker Web Management UI Server": net start nwui
  3. Conecte-se ao banco de dados do NWUI com psql:
"C:\Program Files\EMC NetWorker\nwui\monitoring\postgres\12\bin\psql" -U nwuiuser -d nwui -p 5435
  1. Altere a senha "nwuiruser" para a senha do keystore NWUI: ALTER USER nwuiuser WITH PASSWORD 'password';
  2. Saia da conexão psql: quit
  3. Interrompa os serviços "NetWorker WebUI Database" e "NetWorker Web Management UI Server" : net stop nwui
  4. Crie um novo arquivo nwuidb.conf:
notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\nwuidb.conf"
  • Digite a codificação Base64 da senha> do keystore <NWUI no novo arquivo nwuidb.conf: https://www.base64encode.org/
  • Salve a alteração no novo arquivo nwuidb.conf.
  1. Reverta o pg_hba.conf:
 copy "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf_original" "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf"
  1. Inicie os serviços "NetWorker WebUI Database" e "NetWorker Web Management UI Server": net start nwui
  2. Confirme o monitoringdbpasswordalias foi criado no repositório de chaves do NWUI:
"C:\Program Files\NRE\java\jre1.8.0_321\bin\keytool.exe" -list -keystore  "C:\Program Files\EMC NetWorker\nwui\monitoring\app\conf\nwui.keystore"

 

  1.  Confirme se o sintoma não é mais identificado na NWUI.
