Cause

这不是 DPA 问题。
更改注册表项时,可能会导致此问题。
如果客户的安全团队启用的内部策略限制了注册表项,则可能会发生这种情况。

请注意上面的未知: getEnable8dot3(Unknown Source)

若要确认,请在命令提示符下运行以下命令:

C:\Windows\system32>reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\ /v NtfsDisable8dot3NameCreation

此命令导致应用程序服务器和数据存储区服务器上出现相同的消息:

ERROR: The system was unable to find the specified registry key or value

正确的输出如下所示:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
    NtfsDisable8dot3NameCreation    REG_DWORD    0x2

 

Resolution

客户的安全/作系统团队必须检查并禁用 DPA 应用程序和数据存储区服务器上的任何内部策略。

密钥 (NtfsDisable8dot3NameCreation) 必须在值为“REG_DWORD 0x2”的两台服务器的注册表上创建。

要按正确顺序停止和启动的服务器:

  1. 停止 DPA 应用程序服务:

    <install dir>\dpa\services\bin> dpa svc stop
  2. 停止 DPA 数据存储区服务:

    <install dir>\dpa\services\bin> dpa svc stop
  3. 启动 DPA 数据存储区服务:

    <install dir>\dpa\services\bin> dpa svc start
  4. 启动 DPA 应用程序服务:

    <install dir>\dpa\services\bin> dpa svc start

等待几分钟,然后再尝试访问 UI 并再次尝试升级。
