Symptoms
在 DPA 数据存储区上尝试升级后不久,将显示以下错误:
完整的错误消息:
Invocation of this Java Application has caused and InvocationTargetException. This application will now exit (LAX)
“Details”选项卡显示 Java Lang 错误:
java.lang.NullPointerException at com.zerog.ia.installer.LifeCycleManager.getEnable8dot3(Unknown Source) at com.zerog.ia.installer.LifeCycleManager.a6(Unknown Source) at com.zerog.ia.installer.LifeCycleManager.executeApplication(Unknown Source) at com.zerog.ia.installer.Main.main(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.zerog.lax.LAX.launch(Unknown Source) at com.zerog.lax.LAX.main(Unknown Source)
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:
-
停止 DPA 应用程序服务:
<install dir>\dpa\services\bin> dpa svc stop
-
停止 DPA 数据存储区服务:
<install dir>\dpa\services\bin> dpa svc stop
-
启动 DPA 数据存储区服务:
<install dir>\dpa\services\bin> dpa svc start
-
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。
