完整的錯誤訊息:
Invocation of this Java Application has caused and InvocationTargetException. This application will now exit (LAX)
Details (詳細資料) 標籤會顯示 Java Lang 錯誤:
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
這不是 DPA 問題。
當註冊表項已更改時,可能導致此問題。
如果客戶安全團隊啟用的內部策略限制了註冊表項,則可能會發生這種情況。
請注意上述未知項目: getEnable8dot3(Unknown Source)
若要確認,請在命令提示符下執行以下命令:
C:\Windows\system32>reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\ /v NtfsDisable8dot3NameCreation
此命令導致應用程式和資料儲存伺服器上出現相同的訊息:
ERROR: The system was unable to find the specified registry key or value
正確的輸出如下所示:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem NtfsDisable8dot3NameCreation REG_DWORD 0x2
Resolution
客戶的安全性/作業系統團隊必須檢查並停用 DPA 應用程式和資料存放區伺服器上的任何內部原則。
必須在兩個伺服器的登錄檔中使用值「REG_DWORD 0x2」來建立金鑰 (NtfsDisable8dot3NameCreation)。
要停止和以正確順序啟動的伺服器:
-
停止 DPA 應用程式服務:
<install dir>\dpa\services\bin> dpa svc stop
-
停止 DPA 資料存放區服務:
<install dir>\dpa\services\bin> dpa svc stop
-
啟動 DPA 資料存放區服務:
<install dir>\dpa\services\bin> dpa svc start
-
啟動 DPA 應用程式服務:
<install dir>\dpa\services\bin> dpa svc start
請等待幾分鐘,然後再嘗試存取 UI 並嘗試再次升級。
