Cause

監控程序需要 NWUI 金鑰存放區的權限，才能填入儀表板資訊。可使用 "monitoringdbpasswordalias" 別名已從 NWUI 金鑰存放區 （NWUI.keystore） 檔案中移除，且監控程序無法驗證。失蹤的原因 "monitoringdbpasswordalias" 別名未知。

NWUI 金鑰存放區應顯示 "monitoringdbpasswordalias" 別名：

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

受影響的環境缺少 "monitoringdbpasswordalias" 別名：

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"

Resolution

可使用 "monitoringdbpasswordalias" 別名必須在 NWUI 金鑰存放區中重新建立。必須使用 NWUI 金鑰存放區密碼，才能驗證至 NWUI 金鑰存放區檔案。在此過程中，應使用 NWUI 金鑰存放區密碼來 <取代密碼>。
 

  1. 使用 「以系統管理員身分執行」 選項開啟命令提示字元視窗。
  2. 建立 pg_hba.conf 的複本：
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. 使用文字編輯器開啟 pg_hba.conf 檔案：
notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf"
  • 將檔案底部所有未註解使用者的方法從「md5」變更為「trust」
  • 將變更儲存至 pg_hba.conf
  1. 停止 「NetWorker WebUI 資料庫」 和 「NetWorker Web 管理 UI 伺服器」 services: net stop nwui
  2. 啟動 「NetWorker WebUI 資料庫」 和「NetWorker Web 管理 UI 伺服器」服務： net start nwui
  3. 連線至 NWUI 資料庫 psql：
"C:\Program Files\EMC NetWorker\nwui\monitoring\postgres\12\bin\psql" -U nwuiuser -d nwui -p 5435
  1. 將 「nwuiruser」 密碼變更為 NWUI 金鑰存放區密碼： ALTER USER nwuiuser WITH PASSWORD 'password';
  2. 結束psql 連線： quit
  3. 停止 「NetWorker WebUI 資料庫」 和 「NetWorker Web 管理 UI 伺服器」 服務： net stop nwui
  4. 建立新檔案 nwuidb.conf：
notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\nwuidb.conf"
  • 將 NWUI 金鑰存放區密碼 <密碼> 的 Base64 編碼輸入到新的 nwuidb.conf 檔案中： https://www.base64encode.org/
  • 將變更儲存至新的 nwuidb.conf 檔案。
  1. 還原 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. 啟動 「NetWorker WebUI 資料庫」和「NetWorker Web 管理 UI 伺服器」服務： net start nwui
  2. 確認 monitoringdbpasswordalias 已在 NWUI 金鑰存放區中建立：
"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.  驗證 NWUI 中不再發生症狀。
