Overvågningsprocessen kræver tilladelser til NWUI-nøglelageret for at udfylde dashboardoplysningerne. Ikonet "monitoringdbpasswordalias" Aliasset er blevet fjernet fra NWUI keystore-filen (nwui.keystore), og overvågningsprocessen kan ikke godkendes. Årsagen til den manglende "monitoringdbpasswordalias" Alias kendes ikke.

NWUI-nøglelageret 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

Ikonet "monitoringdbpasswordalias" Aliasset skal oprettes igen i NWUI-nøglelageret. NWUI-adgangskoden til nøglelageret er påkrævet for at godkende i NWUI-nøglelagerfilen. I proceduren skal NWUI keystore-adgangskoden bruges i stedet for <adgangskoden>.
 

1. Åbn et kommandopromptvindue med indstillingen "Kør som administrator".
2. Opret en kopi af 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. Åbn filen pg_hba.conf med et tekstredigeringsprogram:

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

• Skift METODEN fra "md5" til "tillid" for alle de ukommenterede brugere nederst i filen
• Gem ændringerne på pg_hba.conf

4. Stop "NetWorker WebUI Database" og "NetWorker Web Management UI Server" services: net stop nwui
5. Start tjenesterne "NetWorker WebUI Database" og "NetWorker Web Management UI Server": net start nwui
6. Opret forbindelse til NWUI-databasen med psql:

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

1. Skift adgangskoden "nwuiruser" til adgangskoden til NWUI keystore: ALTER USER nwuiuser WITH PASSWORD 'password';
2. Afslutpsql-forbindelsen: quit
3. Stop servicerne "NetWorker WebUI Database" og "NetWorker Web Management UI Server": net stop nwui
4. Opret en ny fil nwuidb.conf:

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

• Indtast Base64-koden for adgangskoden til NWUI-adgangskoden <> til nøglelageret i den nye nwuidb.conf-fil: https://www.base64encode.org/
• Gem ændringen i den nye nwuidb.conf-fil.

9. Gendan 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 tjenesterne "NetWorker WebUI Database" og "NetWorker Web Management UI Server": net start nwui
11. Bekræft monitoringdbpasswordalias blev oprettet i NWUI keystore:

"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.  Bekræft, at symptomet ikke længere forekommer i NWUI.
