Windows 7\Windows 8\Windows 2008 配置DB2客户端 CCA3054N 问题解决办法

ERR messgae:
CCA3054N  The ODBC DSN could not be registered.

Explanation: 
The ODBC DSN registration attempt failed.
User response: 
Verify that ODBC is installed properly and is functional.




Cause

The error is caused by the Microsoft UAC (User Account Control) feature included in Windows Vista, 7, and 2008. In order to create a system DSN, local administrative privileges are required. Even if the logon user is a local administrator, the UAC feature causes the logon user to only include the standard user token. As a result,Configuration Assistant will not be able to detect the administrative authority and the process of trying to add the system DSN will fail.

Resolving the problem

To resolve the problem, the Configuration Assistant must be explicitly launched with administrative privileges. To do this, right-click on the Configuration Assistant icon in the start menu and select the option to "Run as Administrator". Once the Configuration Assistant is launched, retry the previous steps that caused the CCA3054N error and it should complete successfully and create a system DSN on the machine.
