Cause

监视过程需要 NWUI 密钥库的权限才能填充控制面板信息。而 "monitoringdbpasswordalias" 别名已从 NWUI 密钥库 （nwui.keystore） 文件中删除，并且监视进程无法进行身份验证。失踪的原因 "monitoringdbpasswordalias" 别名未知。

NWUI 密钥库应显示 "monitoringdbpasswordalias" 别名：

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

受影响的环境缺少 "monitoringdbpasswordalias" 别名：

Resolution

而 "monitoringdbpasswordalias" 必须在 NWUI 密钥库中重新创建别名。需要 NWUI 密钥库密码才能向 NWUI 密钥库文件进行身份验证。在此过程中，应使用 <NWUI 密钥库密码代替密码>。
 

  1. 使用 “以管理员身份运行” 选项打开命令提示符窗口。
  2. 创建 pg_hba.conf 的副本：
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. 使用文本编辑器打开 pg_hba.conf 文件：
notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\pg_hba.conf"
  • 将文件底部所有未注释用户的 METHOD 从“md5”更改为“trust”
  • 保存对 pg_hba.conf 的更改
  1. 停止 “NetWorker WebUI 数据库” 和 “NetWorker Web Management UI 服务器” services: net stop nwui
  2. 启动 “NetWorker WebUI 数据库” 和“NetWorker Web Management UI 服务器”服务： net start nwui
  3. 使用 连接到 NWUI 数据库 psql：
"C:\Program Files\EMC NetWorker\nwui\monitoring\postgres\12\bin\psql" -U nwuiuser -d nwui -p 5435
  1. 将 “nwuiruser” 密码更改为 NWUI 密钥库密码： ALTER USER nwuiuser WITH PASSWORD 'password';
  2. 退出psql 连接： quit
  3. 停止 “NetWorker WebUI 数据库” 和 “NetWorker Web Management UI 服务器” 服务： net stop nwui
  4. 创建新文件 nwuidb.conf：
notepad "C:\Program Files\EMC NetWorker\nwui\monitoring\nwuidb\pgdata\nwuidb.conf"
  • 在新的 nwuidb.conf 文件中输入 NWUI 密钥库密码 <密码的> Base64 编码： https://www.base64encode.org/
  • 保存对新 nwuidb.conf文件的更改。
  1. 恢复 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. 启动 “NetWorker WebUI 数据库”和“NetWorker Web Management UI 服务器”服务： net start nwui
  2. 确认 monitoringdbpasswordalias 是在 NWUI 密钥库中创建的：
"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.  验证是否在 NWUI 中不再遇到症状。
