我在SQL Server 2012 SP1 Reporting Services实例中设置订阅,该实例将34MB文件导出到Excel 2007-2013 XLSX OpenXML渲染扩展。订阅会引发以下错误:
System.IO.IsolatedStorage.IsolatedStorageException:无法确定域的身份。
我确认可以将报表管理器中的报表导出到Excel 2007-2013 XLSX OpenXML渲染扩展程序而不会出现问题。仅在通过订阅执行报表时才会出现此错误。我研究了这个并在网上找到了以下建议:
建议错开订阅,以便一次只运行一个订阅。这没有用,因为在发生错误时只有一个订阅正在运行。
建议使用Excel 2003呈现方法并将行分成单独的选项卡以避免65,536行限制。我确实证实了这一点,但从业务利益相关者的角度来看,这不是一个可接受的解决方案。
注释表示使用Excel 2007-2013渲染方法的任何报告,其大小超过10 MB,从内存生成切换到使用独立存储。没有解释为什么这很糟糕,我认为这是有充分理由的 - 也许是为了限制RAM消耗。
建议在ASP.NET应用程序的Isolated Storage文件夹中提升用户的权限。我无法找到Reporting Services文件夹所在的位置。
建议使用额外的代码包装ASP.NET的隔离存储代码,以绕过此问题。我找不到将此解决方案应用于Reporting Services的方法,因为这是Microsoft提供的产品。
建议修改报表管理器和报表服务器web.config文件,以在httpRuntime节点中包含maxRequestLength =“200000”。这并没有改变结果。
建议在RSReportServer.config中显式增加内存设置。这似乎不会有所帮助,因为错误与隔离存储有关,但我尝试了它的解压缩。这并没有改变结果。
建议将DatabaseQueryTimeout值从120更改为更大的值。这并没有改变结果。
建议更改订阅执行超时值。这并没有改变结果。

您可以在此处找到解决方案:http://rekiwi.blogspot.com/2008/12/unable-to-determine-identity-of-domain.html
在COM组件中,使用适当的证据创建一个新的AppDomain并执行该代码。
以下是为我解决问题的代码示例:
AppDomainSetup setup = new AppDomainSetup();
setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory.ToString();
//Then we need our evidence
System.Security.Policy.Evidence evidence = new System.Security.Policy.Evidence();
evidence.AddHost(new System.Security.Policy.Zone(System.Security.SecurityZone.MyComputer));
//Now we can fire up an AppDomain running with that evidence.
AppDomain domain = AppDomain.CreateDomain("YourDll.YourClass", evidence, setup);
YourDll.YourClass yourclass = (YourDll.YourClass)domain.CreateInstanceAndUnwrap(typeof(YourDll.YourClass).Assembly.FullName, typeof(YourDll.YourClass).FullName);
yourclass.CallYourMethod();
您希望通过AppDomains编组的任何类型都必须标记为[Serializable()],并且必须从MarshalByRefObject继承。 例如:
namespace YourDll
{
[Serializable()]
public class YourClass: MarshalByRefObject
{
...
