Overvåkingsprosessen trenger tillatelser til NWUI-nøkkellageret for å fylle ut instrumentbordinformasjonen. Informasjonen i "monitoringdbpasswordalias" Aliaset er fjernet fra NWUI-nøkkellagerfilen (nwui.keystore), og overvåkingsprosessen kan ikke godkjenne. Årsaken til de savnede "monitoringdbpasswordalias" Aliaset er ikke kjent.

NWUI-nøkkellageret skal vise "monitoringdbpasswordalias" Alias:

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

Informasjonen i "monitoringdbpasswordalias" aliaset må opprettes på nytt i NWUI-nøkkellageret. NWUI-nøkkellagerpassordet kreves for å autentisere i NWUI-nøkkellagerfilen. I prosedyren bør passordet for NWUI-nøkkellageret brukes i stedet for <passord>.
 

1. Åpne et ledetekstvindu med alternativet "Kjør som administrator".
2. Lag en kopi av 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"

3. Åpne pg_hba.conf-filen med et tekstredigeringsprogram:

notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf"

• Endre METHOD fra "md5" til "trust" for alle ikke-kommenterte brukere nederst i filen
• Lagre endringene til pg_hba.conf

4. Stopp «NetWorker WebUI Database» og «NetWorker Web Management UI Server» services: net stop nwui
5. Start tjenestene for NetWorker WebUI Database og NetWorker Web Management UI Server: net start nwui
6. Koble til NWUI-databasen med psql:

"C:\Program Files\EMC NetWorker\nwui\monitoring\postgres\12\bin\psql" -U nwuiuser -d nwui -p 5435

1. Endre "nwuiruser" passord til NWUI keystore passord: ALTER USER nwuiuser WITH PASSWORD 'password';
2. AvsluttPSQL-tilkoblingen: quit
3. Stopp tjenestene for NetWorker WebUI Database og NetWorker Web Management UI Server : net stop nwui
4. Opprett en ny fil nwuidb.conf:

notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\nwuidb.conf"

• Skriv inn Base64-koden til NWUI-nøkkellagerpassordpassordet <> i den nye nwuidb.conf-filen: https://www.base64encode.org/
• Lagre endringen i den nye nwuidb.conf-filen.

9. Tilbakestill 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"

10. Start tjenestene for NetWorker WebUI Database og NetWorker Web Management UI Server: net start nwui
11. Bekreft monitoringdbpasswordalias ble opprettet i NWUI-nøkkellageret:

"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"

12.  Valider at symptomet ikke lenger oppstår i NWUI.
