我在 SQL Server 2012 SP1 Reporting Services 实例中设置了订阅,该实例将 34MB 文件导出到 Excel 2007-2013 XLSX OpenXML 渲染扩展。订阅抛出以下错误:
System.IO.IsolatedStorage.IsolatedStorageException:无法确定域的身份。
我验证了可以毫无问题地将报表从报表管理器导出到 Excel 2007-2013 XLSX OpenXML 渲染扩展。仅当通过订阅执行报表时才会出现此错误。我对此进行了研究,并在网上找到了以下建议:
建议错开订阅,以便一次仅运行一个。这没有帮助,因为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。我确实验证了这一点,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。
注释指出任何使用 Excel 2007-2013 渲染方法且大小超过 10 MB 的报表都会从在内存中生成切换为使用独立存储。没有解释为什么这样做很糟糕,我认为这样做是有充分理由的——也许是为了限制 RAM 消耗。
关于提升 ASP.NET 应用程序的独立存储文件夹中的用户权限的建议。我找不到 Reporting Services 的独立存储文件夹所在的位置。
建议使用额外的代码包装 ASP.NET 的独立存储代码,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。这似乎没有帮助,因为错误与独立存储有关,但我出于绝望而尝试了它。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。
更改订阅执行超时值的建议。这并没有改变结果。

最佳答案
您可以在这里找到解决方案: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 并执行其中的代码。
这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();
您想要跨 AppDomain 编码的任何类型都必须标记为 [Serialized()],并且必须从 MarshalByRefObject 继承。 例如:
namespace YourDll
{
[Serializable()]
public class YourClass: MarshalByRefObject
{
...
