ReadTrace目前不Support SQL Server 2012的Trace File要怎麼辦呢?
以下透過Power Shell來將SQL 2012的Trace File改成SQL 2008的Trace File。

ReadTrace目前使用SQL 2008的Client，所以如果要使用的話，需要裝Microsoft® SQL Server® 2008 R2 SP2 功能套件。

可參考:RML Utilities and SQL Server 2012。

當我裝了之後，又遇到另一個問題!

什麼!不Support SQL 2012的Trace File。訊息如下，

The major version number (11) in the trace file header is not a supported file version.
At this time only Microsoft SQL Server 2000, 2005 and 2008 trace files are supported. The current trace version (11) is not supported.
ERROR: Read of file header for file E:\GSS\TechInfo\SQL\4.Trace\5.ReadTrace\ReadTrace.trc failed with operating system error 0x8007000D (The data is invalid)
*** ERROR: Attempt to initialize trace file reader failed with operating system error 0x8007000D (The data is invalid)
Reads completed - Global Error Status 0xfffffffe
Shutting down the worker thread message queues.
Waiting for the worker threads to complete final actions.

後來找到網路上的高手，發現可以將SQL 2012的Trace File改成2008的格式(真是利害!)

請參考:More on converting Trace Files

Copy他提供的Power shell script，修改一下$fileName變數成我SQL 2012的Trace File Path，然後執行它，如下，
