Question

当我尝试使用服务帐户凭据启动nservicebus.host.exe时，我收到以下异常：

    Database was not configured through Database method.

如果我使用自己的帐户运行主机，一切正常，但如果我将主机作为具有域凭据的服务运行，或者使用RunAs命令使用相同的凭据，我会得到上述异常。我需要配置哪些权限才能使服务正常工作？

这是我的配置：

        var configure = NServiceBus.Configure.With()
            .Log4Net<Log4NetLoggerAdapter>(a => { })
            .UnityBuilder(container)
            .XmlSerializer()
            .RijndaelEncryptionService()
            .MsmqTransport()
                .IsTransactional(false)
                .PurgeOnStartup(false)
                .MsmqSubscriptionStorage();

        configure.Configurer.ConfigureComponent<MsmqSubscriptionStorage>(
                    ComponentCallModelEnum.None).ConfigureProperty(p => p.DontUseExternalTransaction
                    , true
                );

        IBus bus = configure.UnicastBus()
            .ImpersonateSender(true)
            .LoadMessageHandlers()
            .Sagas()
            .NHibernateSagaPersister()
        .CreateBus()
        .Start();

我有一个NServiceBus.Host.exe.config文件，其中包含以下内容：

＆lt;？xml version =“1.0”encoding =“utf-8”？＆gt; ＆LT;结构＆gt; ＆lt; startup useLegacyV2RuntimeActivationPolicy =“true”＆gt; ＆lt; supportedRuntime version =“v4.0”/＆gt; ＆LT; /启动＆GT; ＆LT; /结构＆gt;

当暂时给所有人和ANONYMOUS LOGON完全控制所指定的目录时会发生什么？如果这解决了异常，那肯定是一个安全问题。你在使用| DataDirectory |在你的连接字符串？您确定该过程实际上是在查看您认为正在查看的目录吗？

接下来，我会尝试在内存连接字符串设置中使用SQLite，看看它是否能够至少创建一个数据库并使用它：

":memory:;Version=3;New=True;Pooling=True;Max Pool Size=1;"

上面的字符串使用内存中的SQLite，但保持单个连接打开，以便表和数据继续存在，直到进程退出。

我将使用的另一个策略是将saga persister更改为另一种SQL风格，例如MS SQL，以查看是否能解决它。
