在新UAT服務器上，需要將tempdb放置在SSD（固態硬盤）上。由于SSD（固態硬盤）特性，所以tempdb的文件只能放置在D盤下面，而不能是D盤下的某一個目錄下面。

ALTER DATABASE tempdb

MODIFYFILE(name='tempdev', filename='D:/tempdb.mdf') ;

GO

ALTER DATABASE tempdb

MODIFYFILE(name='templog', filename='D:/templog.ldf') ;

GO

修改了tempdb的目錄后，重啟數據庫服務，結果出現錯誤信息：“FCB::Open failed: Could not open file D:/tempdb.mdf for file number 1. OS error: 2(The system cannot find the file specified.)" ，具體錯誤信息如下所示：
