Question

想知道选择Redhat或Windows 2003 Server是否重要（可靠性）？假设两者都有相同的技能。感谢

如果您检查glassfish源，特别是./appserv-commons/src/java/com/sun/enterprise/util/io/FileUtils.java，您将看到Glassfish经历的所有扭曲，以便在Windows上删除/重命名文件和目录。

这是一个Windows问题，其限制是删除和重命名打开的文件。

其中有各种各样的技巧，包括多次从JVM请求GC以期关闭文件流，“伪”重命名，睡眠尝试循环。

一些例子：

/**
 *Attempts to delete files that could not be deleted earlier and were not overwritten.
 *<p>
 *On Windows, the method requests garbage collection which may unlock locked
 *files. (The JarFile finalizer closes the file.)

/*
     *On Windows, as long as not all leftover files have been cleaned and we have not
     *run the max. number of retries, try again to trigger gc and delete
     *each remaining leftover file.
     */

/**
 * Windows has BIG issues renaming a directory that is open somnewhere -- e.g. if
 * a DOS box is opened anywhere in that directory.
 * This method will try to do a "virtual renaming" if there are problems
 * I.e. it attempts to do a simple rename, if that fails it will copy everything under
 * the original directory to the renamed directory.  Then it will delete everything
 * under the original directory that the OS will allow it to.

实际上，这有时会转换为Windows上的borked部署或重新部署，因为某些文件无法删除或移动，最终会被遗忘。在我运行的50个左右的Glassfish实例中，我在Solaris 10上从未遇到过任何问题，并且在Windows上始终存在与此相关的问题。

简而言之，任何* NIX都会因为这个原因而更好，除了其他平台管理员考虑因素。

我认为你会发现大多数人会认为Redhat胜过Windows可靠性。 Glassfish本身也应该运行相同的。
