我创建的以“dotNetChat_”开头的表在重启MySQL后消失

Question

根据新信息，我创建了一个新问题here，可以更好地解释我打算解决的问题。

我正在尝试在MySQL中创建一组表，这些表都以prefrix dotNetChat_开头。最初我将这些表设置在另一台服务器上，尽管它们配置了相同的my.ini文件，但一切正常。每当我第一次创建这些表时，它们都会正常显示，但在重新启动MySQL后，它们会“消失”，并尝试使用MySQL Workbench加载表内容，从而产生以下错误：

  

错误代码：1146。表'thepwf_prgminteractions.dotnetchat_testtable'不存在

我检查了我的错误日志文件，这是我发现的：

在考虑检查我的日志文件之前，我认为服务器可能有问题，所以我卸载了服务器，删除了所有服务器数据文件，重新安装了它，放了我已经配置的my.ini配置文件已经做好了准备，并开始做好准备。这可能是什么问题？每当我尝试删除任何包含或包含此类表的模式时，我都会从MySQL Workbench中收到以下错误：

编辑：我已经继续玩了一段时间了，并且在使用IOBit确保所有MySQL文件在重新安装之前被删除之后，我在尝试时遇到错误导入表格。 MySQL Workbench的错误是无用的，但是错误日志中的内容可能会有所帮助。

我会说，由于某种原因，MySQL被拒绝访问InnoDB文件，然后无法加载，并且没有它们就继续。你能否验证你的进程没有运行两次，并且MySQL用户是在有权访问MySQL lib目录的帐户下运行的。

我的研究结果基于这个错误：

[ERROR] InnoDB: Failed to find tablespace for table "thepwf_prgminteractions"."dotnetchat_testtable" in the cache. Attempting to load the tablespace with space id 24.
2014-03-05 18:05:33 0x1f30  InnoDB: Operating system error number 32 in a file operation.
InnoDB: The error means that another program is using InnoDB's files.
InnoDB: This might be a backup or antivirus software or another instance

错误32，基于http://msdn.microsoft.com/en-us/library/windows/desktop/ms681382(v=vs.85).aspx表示：

ERROR_SHARING_VIOLATION
32 (0x20)
The process cannot access the file because it is being used by another process.

正如我所说，这意味着文件被另一个进程锁定。当你重新启动MySQL时会发生这种情况，因为当你创建MySQL时，MySQL会让它们打开，而另一个进程无法锁定它们。一旦MySQL服务停止（重启），另一个进程就会锁定文件，MySQL再次启动时无法打开它们。

要查看系统上的锁定文件以及锁定哪个进程，您可以使用http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx

您需要以管理员身份运行CMD Prompt，并键入以下内容：

handle.exe thepwf_

哪个应该显示哪个进程正在锁定文件。
